It provides you with a durable, hard to stain surface and with some of the most beautiful textures and patterns available.


Slate flooring is often purchased as slate flooring tile.There is tremendous assortment accessible when hoping to source slate tiles; this changeable rock can be found in various hues and molded tiles which takes into account genuine singularity. Slate tiles offer an actually slip-resistance surface and can in this manner be the perfect ground surface for a kitchen or lavatory. The tile can be purchased in a variety of shapes to make any design or pattern that you want. High temperatures take very tiny particles of clay and silt and bond them closely. The resulting stone is impermeable so liquids don’t penetrate readily. This leaves you with very few stains and virtually no cracking (as long as it is laid correctly, that is.)

Installing And Caring For Slate Flooring


When it comes to installing slate flooring, you should consider calling in the professionals. If you are a capable do-it-yourselfer, you can do the work on your own, otherwise step aside for a professional. Some words of caution though. You need to ensure that you cut the slate properly or go with precut tile pieces. If it is cut improperly with the wrong tools, it will snap, reducing its value and usability. Also, it is important that you pay attention to the grouting process. Because of the natural texture of slate, you will have a more difficult time grouting. You can avoid this by grouting after you have sealed the flooring.For whatever length of time that the slate ground surface is introduced on an appropriate sub-floor, your slate deck ought to be exceedingly impervious to any sort of harm. On the off chance that you have any uncertainty about the suitability of the surface where you need to introduce your slate flooring, it is best to counsel an expert before you endeavor any establishment methods. A note about sealants: if you opt for a high shine sealer, the dirt and dust of every day use will show more than a low-sheen sealer.


As for how to clean slate flooring, you will use the same method that you would for the care of stone flooring of any type. A bucket of warm water without any powerful chemicals is the best method. Keep up on the maintenance of sealants, as well as keeping the grout chip free, to maintain the integrity and beauty of the slate.Slate is a natural stone and will require in-depth knowledge of the exact products that will achieve the best possible clean without damage. Industrial-strength rotary cleaning machines are then used to agitate the cleaning solution, which is then rinsed thoroughly and dried.


Slate flooring is beautiful and durable. Not only do the color choices make a statement, but the textures add interest not found in most other stone floorings. Slate is an excellent choice for your flooring needs. It’s an excellent choice for an entryway, kitchen, sun room, or even living and dining rooms.

  1. Hi, I have read so much information on laying slate tiles. I recently found at Home Depot slate tiles that are irregular, but are actually a type of pattern meshed together to form a shape. I already purchased thinset- but recently read I should maybe use a medium bed mortar. What is your opinion? Oh by the way, I am laying this slat found in the garden section on a front porch, which includes a step to the side walk and a step up to the house – any recommendations or thoughts would be welcomed!

  2. I could really use some more information about the slate you’re planning to install. I looked at Home Depot (online) in the garden section and didn’t see any listed for online or in store shopping.
    Some things to take into consideration are how thick the slate is, if it’s real slate vs. shale (real slate is much more durable/long lasting), is your porch covered or open and the weather in your part of the country.
    I do think your idea of a medium set would be a good choice, especially since the steps and at least some parts of the porch will get a good deal of foot traffic, and I’m guessing that you’ll probably have some patio furniture as well.
    Sealing your slate is also very important – so don’t forget that last important step! That subject is also covered at this site.

  3. I have a question about slate floors? We are remodeling our bathroom and we are using multicolor slate for the floors(12×12) and around the bath/shower(4×4). The salesperson at Home Depot told us we shouldn’t hang slate on the walls b/c it is too heavy? We kinda compared several different tiles with the slate and most of them seemed to be about the same wt. What do you think? Also I know you specialize in floors but, what color do you think is the best color for the walls with a slate floor?


  5. Hi Danielle!
    I don’t see why installing slate on the walls should be a problem as long as the walls are sturdy enough and so long as the manufacturer’s instructions are followed. You could also call the manufacturer to see if they think it’s ok as well. As far as what color would look best, I haven’t a clue! :~) I don’t know what colors you’ve decorated with. The colors are really up to you – YOU know what YOU like.

  6. Hi Patty! Have you tried using a microfiber mop? That might help. The floor has been sealed well hasn’t it? Is the slate rough around the edges or on top too? Are the slates a bit uneven? Slate is sharp and as you know, mop strings can get caught if your floor has any of these characteristics. Hope a microfiber mop works better for you!

  7. There is a white residue on our slate floors where the ridges are on each piece. Do you know whatis causing this and what might remove it?

  8. Hi Rose,
    Are you referring to the edges of the tiles? I’m sorry, I’m not exactly sure what you mean by ‘ridges’. Have you noticed this ever since it was installed or has it begun recently? How long since it was sealed/polished? What kind of a floor is this covering/what room/what level of the house. Sorry, lots of variables to try to narrow down what’s going on.
    If it’s along the edges, it could be that the grout wasn’t completely removed from the edges before it was sealed and/or polished.
    If the ridges that you refer to are throughout the tile surface then it could be a couple things:
    1. You have moisture coming up from beneath the tile, probably because there’s not a good moisture barrier underneath.
    2. The floor was inappropriately sealed/polished, possibly with products that were not created specifically for slate/stone flooring.
    3. It could just be time to strip and reseal.
    If you cold give me some more info it’d be much appreciated, then I could help you better.

  9. just layed grey slate floor in kitchen. it is a bit dull looking was wondering what we could do to give it a slight sheen rather than a bright shine.

  10. Hi Gerry,
    Basically, it’s matter of how high of a traffic area you have and when it looks like it’s time to reseal your flooring. I think you might be actually be talking about when to strip the finish, not the sealer. The sealer is still ok so long as water beads up. Just be sure that whatever you use is formulated to strip whatever is already on your floor and be sure that what you use to reseal or refinish your flooring is formulated for your specific flooring type. As far as how to do this, be sure to follow the instructions on the label, and check out the product(s) website(s) for more helpful hints, information etc. There will probably be a phone number on the website you can use to contact them if you feel the need to talk to a real live person. ;~)

  11. I just purchased slate from Homedepot. They are all assorted colors. How do you start to decide hw to lay. I have chosen the brick pattern but should I lay by color or just grab and lay. Totally overwhelmed

  12. What is the product line called or the SKU (upc) number? I’m looking at Home Depot and not finding any – I was wanting to see just what you bought so I could find out more info about it.
    What room are you installing this in? What kind of floor is already there where you’re going to lay this slate down?
    As far as what colors to lay where, it’s really up to you. I’d suggest getting some of the bricks out and setting them down both ways (by color and by just grabbing out of the box) and see what you think. It’s pretty hard for me to give an opinion on anything without knowing what the product is.
    Have you done any research to find out what you need to set the tiles? Are you going to need a vapor barrier? Have you decided what you’re going to use to seal & finish the tiles & grout with?

  13. ok thanks for being there! last year We laid a slate floor in our garage. It is a mess….all faded from a once black to faded grey, spotty and frustrating. I scrubbed the life out of it today, and now am faced with a problem. Do I reseal the floor. It is a year old. What product can I use. thank you sooo much winnie

  14. Hi Winnie,
    Do you remember if you put a polish on the slate after sealing it? If so, call the manufacturer and find out what they recommend to strip off the polish. You might luck out and not have to reseal if water still beads up on it afterwards. That means it’s still sealed and all you’ll have to do is apply at least a couple coats of polish.
    If you don’t remember what you’ve used, read through the articles, questions & answers here. You can also use the search function at the top of the page on the right-hand side.

  15. hello and thanks for replying. this moning the floor looks smoky and dreadful. As I already said, it was black slate and is now a smoky grey and black in spots Can you suggest a good polish remover. Then, what product should I finish it with, or is it a goner? I am so dissappointed with this floor. Does it have anything to do with the cars, it is grey even where the cars are not parked. you have to see it to believe it. thanks so much…winnie

  16. Hi Winnie,
    I cannot tell you for sure what’s going on, but I’m guessing there must be some sort of moisture issue since it sounds like it’s getting hazy (smokey). I obviously can’t know if it’s moisture from under the slate or on top of the slate. You might have to try a few different products to find one that’s going to work for stripping. I say this because we don’t know what was used on your floor.
    I hear good things about Aqua Mix products, so you might want to check into that. Just always be sure follow the directions, if you have questions you can always check out their website or call the phone number on the bottle.
    Hope that helps!

  17. I have tiled and grouted a floor with slate tiles and I have a question. On some of the lighter colored tiles there are what appear to be water marks around the edges. It looks like the tile absorbed moisture from the grout through the edges and there is a line where the water penetrated. Any way to get rid of this or at least make it uniform?

  18. Thanks for the reply but I have some follow up. This doesn’t really look like grout haze and I say this for a two reasons. First, it is darker around the edge of tile and I would have thought a haze would have been lighter. Second, the discoloration is a very uniform darkness around the outside edge of the tile about 1/2″ wide. It looks like a border. I would think that haze would occur anywhere the grout was and it certainly was in more place than that. Also, the same uniform discoloration is on several tiles.

  19. We moved into an old Farmhouse. The kitchen has a slate floor, which was probably nice at one time.The grout is coming out and it looks as if it was never sealed. It has a dull film on it.
    We would like to restore it, regrout, and re-seal it. My husband is very good when it comes to restoring our house. Can you give us any products that would be the best for what we need to do? Tahnks.

  20. Hi Barb!
    Sounds like a project! I know that AquaMix makes very good products for almost any flooring material. The link will take you to their product page that’s just for slate flooring.
    Just be sure that when re-grouting that you have already sealed the slate, or else the grouting can literally get into the slates pores – really difficult to fix if that happens.
    Best of luck – I’ll bet it turns out beautiful!

  21. Yes, you are absolutely right about hiring a professional to install slate.
    I had 900+ ft installed a few years ago by who I “thought” was a professional. The floor turned out a nightmare. Edges were higher than others, tiles were higher than others – you had to tiptoe otherwise risk foot injury.
    I would still not recommend this floor for the interior though. The variations in the stone surface make it hard on your feet.
    I finally had laminate installed and the slate removed. Just enduring the toxic dust from the removing was enough…..with the laminate I can now walk on a soft even smooth surface and my feet are happy again…..
    Think twice before installing slate inside your home – even with excellent installation – hope this saves even one person from the misery I went through of having “that beautiful slate floor inside my home”.

  22. After the installer sealed our slate floor,the slate appeared cloudy. AFter using mineral spirits on the floor, the slate has a more natural look but is quite dull. Should another sealer be applied since the mineral spirits was used?

  23. Hi Jan,
    Why did the installer choose mineral spirits? If I’m reading between the lines correctly, it sounds like he sealed the slate and then discovered it looked horrible and used mineral spirits to hopefully thin out the sealer in hopes of removing the grout haze too? That’s not how it works, the grouting haze is supposed to be removed before it’s sealed.
    If the installer charged you for sealing too, then he needs to come back and make this right if you’re not happy with it, presuming of course, that the sealant wasn’t supposed to leave the slate looking so dull…………. which, reading between the lines again, tells me it shouldn’t.

  24. I have slate flooring in the bathroom and lining the shower walls. I would like it to have some luster to it. The slate has been sealed several times while it was being laid. Is there a product that can give it some type of shine or luster, not necessarily a polished look like my granite.

  25. Hi denipolis,
    Yes, there are products for this. I think that what you want is a high sheen product – something to give it that wet look? There are also low sheen products and no sheen (which I know you don’t want). AquaMix has products for this and, so far, I haven’t heard anything but good about their products. A Lowe’s or Home Depot will probably have similar products as well. Whatever you use, just be sure that it is specifically formulated for slate, follow the direction and don’t be stingy when applying the product. ;~)

  26. Is it ok to toplace slate over existing concrete. This is the way a contractor wants to do my outside work. Can you tell me if I will have problems with this at a later time.Also, I like seams that are small can this be achieved with outside slate. What kind of product will I need to achieve a pattern with small seams.
    Thank you for your input

  27. Hi Laura,
    Yes, this is ok to do, so long as the concrete is sealed against moisture, helps to seal the stones before laying as well (extra moisture control + it makes it easier to clean up grout).
    I don’t know if small grout lines are possible since you did’t mention anything about the overall shape(s) of the slate or what your definition is of “small” seams. So long as the slate edges are straight, you should have no problem placing the stone rather close together.

  28. We recently installed slate and made two mistakes that we found out about after the fact — we didnt preseal the slate before grouting, and we didnt clean the excess grout off well enough before it dried (which was harder because we didnt preseal it). What is the best way to get the excess grout (patches in some places and just haze in others) off? And if/when we get that off, how/when would you recommend sealing it? Thanks.

  29. AquaMix has the products you need. I don’t know if their available in your area or not though. You can find locations that carry their products on their website too.
    After you get all the grout/haze removed, be sure to let your slate dry thoroughly before sealing – or you’ll be in for evem more issues and lots more work. As you have discovered, slate is porous. Give it a few days to dry out really, really well. You can speed up the process with a dehumidifier.

  30. We have recently taken an order of slate tiles, many of the tiles are covered in a white powder which is proving very hard to clean (soap and water). I don’t want to seal the slate with the powdery look. Any ideas on the best way to clean the slate before we seal it?

  31. HELP!
    I have 20-30 year old dark brown slate floors in my kitchen and breezeway with almost as many years worth of Mop ‘n Glow buildup on them. Is there any way of removing this?

  32. Hi Kim,
    I’m sorry to hear of your dilemma. Mop ‘n Glo is notoriously difficult to remove. Use the search box in the upper right hand corner of the page and you’ll see what I mean. You can try what has been suggested in other threads. You might also want to give BioShield a call and see if they know if they have a product to remove it. Heh…. and if so, please post back here! They have wonderful products, but I don’t know if they have a stripper that will remove this stuff.
    If you search at your favorite search engine (mine’s Google), you’ll see that you’re far from alone.
    Good luck!

  33. Researching the installation and maintenance of slate floor tiles – thank you one and all for your insight and tips (so sorry that I’m learning from others’ mistakes)!

  34. Thanks for the kind comment Molly. Yes, it’s a shame for those who made the mistakes, but at least others can learn from them so that hopefully somebody will be prevented from making the same mistakes. ;~)

  35. I have been warned about using limestone tile for flooring in the kitchen and entry areas (we active dogs and kids) and am considering quartzite tiles as an alternative. Now I have been told that some quartzite can be quite porous even though it has a high Moh value. Would you recommend using limestone or quartzite tiles for an active household, especially in the kitchen? Can you recommend a natural stone alternative for our consideration?

  36. Hi Mike,
    I think either option would be good – the biggest thing is to seal before laying and to seal with with a product after grouting that will protect it. Yes, they’re both porous, which is why it’s very important to seal well – so that dirt doesn’t get into those pores as well as other substances that can stain it.

  37. We had several problems installing our slate- first, slate can be difficult to stick down, if the adhesive side is not cleaned and mudded. We have had a lof of our tiles pop up, probably 1 out of 5 tiles has come loose. This is because the contractor simply screeded the floor with thinset and a notched trowel, and did not remove the thin haze of slate dust on the new tiles. This dust has to be removed, and EACH tile has to be coated with mud, and placed on the floor which has been pre-coated with mud and scraped clean. This method allows the slates to really bond with the substrate. Another method i used in my shop to lay the slate is to use a full bed of thinset, not a notched trowel. the slate coated with an oversized gob of thinset, and then pressed down so that thinset oozes from between the neighboring tiles. The thinset is then wiped clean and acts as grout. In my tests this was the best way to lay the slate because grouting was not necessary. It is more time consuming initially. We did not choose to seal the slate- does sealing slate prevent cracking and actual durability of the grout, the slate, and the bond to the substrate? we have tile in the entire first floor of the house except the bedrooms.

  38. Thank you for your advice. Can you elaborate on sealing before laying the tiles and after? Do you seal only the top-side, or should we apply sealer to both sides of the tile and the edges before it is put down? Lastly, we were advised to use an oil-based or solvent-based sealant (511 brand I believe) for best results, do you have preferences for sealers to use before and after grouting?

  39. Hi Nate,
    I found your post very interesting and thank you for posting your method of laying slate. As to your question, yes, you really need to seal slate. Remember, slate is porous and absorbs dirt and can stain if something colored is spilled onto it. Using a sealer will prevent this – just make sure that the sealer you use is formulated for slate or stone.

  40. Having just completed installing slate tile in our bathroom, hearth, fireplace surround and entrance I wish I would found this posting BEFORE doing all this work. I did not clean the under side of the tile and am now concerned the tile will be popping up over the next few months–especially the entrance since this will, obviously, receive the most traffic. What can I do at this point? Is this a common problem? Should I be concerned about this issue? Currently, the tile is sealed–five coats total; three coats before laying and two coats after grouting.

  41. what is the best underlayment for laying slate outside on a stoop? there is currently 50 yr old concrete which was under an old tile that i removed. can slate be set with a sand base and just grouted? can slate be installed with a mastic?

  42. Hi Rory,
    Hopefully you won’t experience any issues. If you do, the only remedy will be to lift up the stones that pop up, clean them well and reset them. You did well though in sealing them before you laid them – a lot of people don’t do that and then have problems getting the grout haze off of the stones or worse yet, seal after laying without getting all of the haze off, leaving them no choice but to strip and re-seal.

  43. Hi Stewart,
    I would not use a sand base as this will allow the slate to shift over time (and it might not be a very long time!) and you’ll have cracking grout all over the place. I would recommend that you make sure to use an adhesive that is recommended for stone that is outdoors. If the mastic you’re thinking about using is recommended for that type of application then you should be safe. If in doubt, call the manufacturer of the mastic product you think you want to use. On the stoop itself, a thinset should work nicely, medium set if the stones are really heavy.

  44. I have a problem. I had new slate steps installed outside about 9 months ago. This winter, I was afraid to use a shovel on them to get rid of ice. So, I used some salt. Now I have whitish stains on the steps. I have tried cleaning with soap and water – but nothing works. Any ideas? I hope they aren’t ruined.I am upset with myself for not thinking they would require special care and upset with my landscaper for not having warned me.

  45. I would try using a product to remove efflorescence, such products can be found at AquaMix. They have a few products that you can use. You didn’t mention if the slate had been sealed or not, if not, you need to do that afterwards – you may still need to even if it has been sealed as the salt may have eaten through it. Just make sure that you use a sealer that’s compatible with any other products used on it before, or to be safe, you can always strip and apply a few fresh coats of sealer.

  46. We recently put in a slate tile flooring in our master bath and some of the thinset was not cleaned off the tiles. I was able to wipe the dry thenset off with a sponge, but doing so created a haze on the tile. What is the best way to get rid of the haze before I grout?

  47. Hi 1st time,
    Actually, you’re supposed to clean off the haze before it dries completely. You’re also supposed to seal the stone before you lay it to make the thinset easier to clean off – it also prevents the chance of the thinset seeping into the stone.
    Anyhoo, go to and look up their product line for slate – they have a category of “problem solvers” – including a product that’ll help get that haze off.

  48. My husband and I just installed 12×12 slate tiles from a local quarry in our entry foyer. The foyer is a small area, only 4×6. While sealing the tiles with a high gloss sealer & finish I noticed that some tiles seemed to not be ‘absorbing’ the sealer as readily as others. Some tiles look a natural dark slate blue in color while the tiles that have been successfully sealed are the desired black color. I inspected a left over tile that had not been installed and what I discovered is…the tile seems to have a smooth side and very subtle textured side…which I believe is probably the face side of the tile. I was unaware that the tile had a face side since we asked the guy who sold us the tiles at the quarry and he said the tiles could be installed any which way. Long story short, the floor like a horrible mixed checkerboard of blue and black and I don’t know what to do now. Can you offer any suggestions?

  49. Hi Shelly,
    If the checkerboard effect is truly a result of which side is facing up, then there won’t be much you can do aside from starting over from scratch. One thing I can suggest is perhaps stripping the tiles (thankfully it’s a small area!) and using an ‘enhancer’ product on it first – basically a sealer. If you look at and go to their slate category, you’ll see what I’m talking about – the term enrich & seal comes to mind. I can’t guarantee that this will work though because of the different faces that are exposed. Ooh, just remembered, there’s an article link for it here: — Good luck!

  50. i`ve just purchased 36m of slate to tile a large kitchen and utility room/shower room.
    as slate can vary so differently in depth. and i dont want the kids stubbing their toes, the company i have used have machined milled all the tiles to an even depth of approx 12mm(plus/minus 2mm) they look absolutely beautiful and i cant wait to lay them. when i have checked some of the tiles, they seem to have a very thin layer of slate that crumbles and comes off very easy leaving a more solid slate underneath. can i just scrape this thin layer off with a scraper without doing any damage to the tiles ? and do you always have to use a wet cutter to cut them to size ?
    kind regards dave

  51. Hi Dave,
    It’s your choice it you want to take that thin layer off, but I wouldn’t. What I would suggest sealing the whole tile before laying. Why? It protects the slate, stabilizes it by encapsulating it (so to speak) and will make it much easier to clean up after grouting. If nothing else, please, please seal the surface before grouting. Slate is very porous and any mess from the grouting will work its way into the pores and be very difficult to clean if off thoroughly.
    Yes, you should use a wet cutter.
    Be sure to use sealers and products that are specifically made for slate. carries a good line, there are others of course.

  52. I installed a slate tile floor in my sunroom about 6 years ago. It is beautiful! As I recall, after installation, we treated the floor with Linseed oil, does that sound right? Since installation, I have done nothng but vacuum and/or sweep the floor.
    Now, I have ordered some new furniture and would like to thoroughly clean the room, prior to the arrival of the furniture.
    I own a Hoover cleaner for hard floors (the kind with the spinning brushes) and think this may be a good tool to use with a mild cleanser to clean the slate. Do you agree?
    Should I treat again with Linseed oil after the cleaning?

  53. Hi Wendy,
    I personally don’t know of anybody who has used linseed oil on their slate, but I suppose it is possible, I don’t think I’d use the Hoover on a slate floor, unless the slate is in exceptionally good condition. I’d be careful in choosing a cleaning product too. Some people will use dish soap thinking that it’d be ok – especially diluted. Dish soaps in general leave a tacky residue. Be sure to use a cleaner specifically formulated for use on stone flooring.

  54. Our lovely slate tile is being installed as I type, but we have one concern: One area that is being tiled is where we keep the upright piano. Will the piano be too heavy and crack the new slate tile, or is the tile pretty resilient? Thanks!

  55. We need to replace the tile under and behind a freestanding woodstove. It is for a home that is vacant and unheated during severe winters, so we need tile that will withstand exteme heat and freeze. We are thinking about slate. Do you have any suggestions for us?

  56. Hi Lanee,
    I don’t know if it will be too heavy or not, it will depend on the thickness of the tile, how good of a subfloor you have, and how heavy the piano is. I really don’t think you’ll have any problems though.

  57. I have a slate floor on an outside deck. I am having a lot of problems with the slate powdering and chipping. What can I do if anything to solve this problem? Thanks

  58. Hi Jeff,
    Sounds to me like this is a soft slate, one that’s not intended for outdoor use, at least in your climate. You can try sealing it with a heavier coat of whatever sealant you’ve selected before.

  59. an installer put my slate tiles on the wrong side. should I have him take them up and put some again on the right side? can you lay slate on the smooth down side and is it as durable?

  60. Hi,
    I purchased slate which came in a kit ranging in sizes..The color is called California Gold. It was actually laid out in the tile store’s floor. I liked it. The tile in the stores was finished with a color enhancer and brightener which darkened the floor and gave it a wet..but matte look..also the tile is textured too which I thought would be nice in my tudor victorian house..I’m going for the stone..iron pewter look with dark trim and vanilla wall…My tile arrived and I have it layed out ..not yet grouted..My tile guys have not put the finish on it yet. The tiles are predominantly gray with touches of browns, reds golds…I think it has too many colors ..and is distracting, a little like an water and gaseoline and oil slick effect. I know I want to use a sealer that darkens and brightens the slate, but I now would like to simply the the grays and blacken the rusts and golds and reds..neutralize it a bit ..I think what a need is more gray blue.. .Is there a stain or paint to achieve this before sealing…I see on your site that you suggest sealing before guys did not get that message..too late for that now.
    thanks for any advice…

  61. I have to choose a floor for a brand new porch/3-season room and I’d love slate. There’s a very thick concrete pad underneath. My concern is that it will heave and flake since we’re in upstate NY and the room is not heated. I also worry about sharp edges on dog feet and noxious sealing products. I fell in love with the India(n) slates but then started looking at the Daltile continental slate porcelain tile (not as nice). (Does the Daltile continental slate Brazilian green have as much variation as the pictures seem to suggest? The sample I saw didn’t seem to.) Do you have any thoughts for me? Thanks.

  62. Hi KMC, you do have legitimate concerns regarding the use of slate for your porch.

    Were you actually able to get a sample of the Daltile or are you just referring to a picture? I would recommend trying to see an actual sample of the Daltile to help you make your decision.

  63. TFL,
    I guess I won’t go with the slate. (I won’t plant palm and coconut trees in the yard either.) The picture of the Daltile Continental Slate in Brazilian Green showed a lot of variation. The sample I saw in the store did not. Actually, I assumed the picture was of a mixture of several colors but it was just the green. Here’s my question then: will larger or smaller tiles show the most variation? My space is 13 x 13 and I need to decide the size of the tiles and whether I want a pattern or straight grid. I want the best chance of looking like slate as possible. Thanks for your thoughts.

  64. Beverly – Maybe you can help me. I saw a picture of a fireplace done in a linear fashion with polished slate tiles about 12×24 and it was spectacular. Well now I’m looking for slate in that shape and can’t find anywhere. Can you lead me in the right direction? I am on Long Island.

  65. HELP! We run a painting company,and recently painted a kitchen with oil and water based paints. The customers weren’t supposed to have the floors down when we began, but they had them installed early. I papered and taped thoroughly, but something apparently got on the floors. Now the owner is saying that on a few of the tiles, the waterborne sealer isn’t being accepted. It could be paint thinner. What to do???!

  66. Liz,
    To give you my opinion on what I think of slate throughout your entire lower level brings up a few questions of my own. Is the lower level a basement? Are you installing yourself or having a professional install? Are you asking if I think it will “look” nice in your home?
    With that said, I personally think slate is beautiful and functional. Why not buy a sample of the slate you want to install and place it throughout your lower level to get a “feel” for how it will look.
    Slate can also be used in a bathroom just remember to properly seal the tile before installation, to protect the tiles from the high moisture content in a bathroom.

  67. I have a coarse textured slate floor which i put down and grouted a few weeks ago in my kitchen- it looks ok. Cleaned with mild alkali and water on numerous occasions but still doesn’t look particularly clean, from reading it seems it needs a sealant, any reccomendations.

  68. I have a slate floor which is sealed well. The small rug in front of the sink unfortunately left the rubber backing on the slate. Because the slate is uneven, I can’t really scrape it. Looking online, recommendation was to use mineral spirits to dissolve the rug backing, but I can’t imagine that won’t leave a grease like stain on the slate. Will the mineral oil remove the rug backing and also the sealer, meaning I will have to reseal that area? I used Professional’s Choice 511 Porous Plus Sealer.
