Customer Questions & Answers

we had 300 sq ft installed after sealing the stone looked so dark. we do not like it anymore what to do? Its lost the multi color look now all black.

Asked by: stoneloversandme1
You should be able to remove the sealer, just find out what type of sealer they applied. Your Home Depot flooring dept. can help find the correct solvent that will be safe for the stone. This stone is very durable, don't loose hope. At the very worst solution, the whole top later could be ground or chipped off to reveal fresh stone. That's pretty drastic however. If you like the look of the natural stone, you really only need to be concerned with sealing the grout. That sealer, applied over the entire 300 sf, should give you the look you want.

We want this flagstone for our small condo patio in Houston, Texas. Will be subjected to rain yet very little frost. Will this hold up?

It seems some people are using this around their pools and outdoor walkways. If this is used on our small patio will it hold up?
Asked by: Mike
Since it is natural stone, it will be fine. Just make sure you have a suitable foundation to apply it over. It will break apart if you apply it over sand. You must have an unmovable base. Seal the grout and you will love it. We bought half a pick-up load from someone that tried to use it on their walkway down to the lake, it did not work. Not because of the weather, but because of the instability of the foundation.

I'm interested in these tiles but the product description contradiction itself, one said it's great for outdoor use and another said it's recommended for indoor use only? I'm thinking to use them for outdoor patio. Please let me now. Thanks! Ms. Wang
Asked by: Anonymous
From what I have read on other sites, people are warned to be careful choosing slate for outdoor use and consider also what part of the country you live. If you live in a cold climate and you have freezing and thawing cycles--there could be issues with cracking and lose tiles. I live in South Texas, and we don't have extreme winters. It hardly freezes, and I did choose this type of product for my outdoor entrance walkway. I really like the look. This is not for everyone, I knew there would be some flaking and some rust that happens naturally. If you are the type of person that likes everything "perfect" even outdoors--don't get this. If you are willing to accept some of nature's imperfections, then you still have to consider other factors before making a final choice.

How many boxes do I need to buy for a room that is 20 feet long and 11 feet wide?

How many boxes do I need to buy for a room that is 20 feet long and 11 feet wide?
Asked by: Steven
Hello Steven, You would need approximately 18 cases of Natural Stone Collection for that room. However, we do recommend speaking to a flooring specialist at your local Home Depot for the exact amount needed for your project.

Rather difficult to work with, and some pieces of the tile (less than 5%) were shipped broken. The actual colors of the tile are not quite and vibrant as the picture, however we ended up very happy with the final result. Would buy again and would recommend.

The final product, our 230 square feet formerly concrete patio, is beautiful but the tiles were pretty hard to work with. There are 7 segments attached to a mesh and it’s almost impossible to lift the entire tile and place it on the adhesive without making a major mess. We decided to separate the segments from the mesh and worked the pattern with individual segments. It reminded me of working on a jigsaw puzzle. It was time consuming but we had better control of both the segments and the gaps between them and because of that we ultimately used 3 boxes less. On the flipside, we needed a lot of grout. 7 large bags of it and the cleanup was long and tedious. I should also mention that the tiles are packed 5 per box and a lot of the individual segments on the mesh were cracked or broken. Since we were separating the segments from the mesh, we just used the broken segments for edging but it was upsetting to see in some cases all 5 tiles having at least one segment broken. Out of 12 boxes that we used up there was not one box that did not have broken segments. Also, the tiles are not flat so you have to be creative how you lay them. The stone is fragile but hard to cut. I would not use this product indoors. You’d never be able to have a clean floor because the surface is uneven. I am giving it 4 stars because I like the final result but it was hard to install. Probably, not exactly a DYI material.

Rated 5 out of 5 by from Fireplace flagstone As advertized. It matches very well some slates flagstone I bought onsale last April. I need this to complete the amount necessary to built up a fireplace bottom to ceiling. Looks great!

Rated 5 out of 5 by from Looks beautiful... This product looks great if you are willing to forgive the stone's natural flaking and there will be some "rust" released once installed. I have read conflicting things on whether one should seal slate or not. So far, we have not sealed it. I love the way our entrance walkway looks now.

Rated 4 out of 5 by from Great-looking stone tile When I went to my local HD store to collect my order, I was quite surprised to see how many boxes were needed to contain the tiles. When I opened the boxes, I understood why. The tiles were surrounded by a great deal of packaging to prevent damage in transit. Even so, one tile was damaged. I don't see this as a big drawback—the package was supposed to contain 13.5 sq ft. of tiles, but to my eye (I didn't measure) it seemed quite a bit more. The tiles come in five groups of 7, with tiles in each group arranged as shown in HD's picture. A light plastic backing holds the tiles in a group together, for ease of laying them out and arranging them, and, I suppose, for ease in grouting between them if that's what you want. I'm using them for a garden path, so I opted to cut the plastic and place them in a more widely spaced pattern, but that was also straightforward. The tiles were mostly grey, but still quite attractive. Altogether, I'm quite pleased with them. I didn't want a pattern of square or rectangular tiles, and this is a great alternative.

Rated 5 out of 5 by from Gorgeous This tile looks beautiful and natural. It is a nice way to get a flagstone look without needing a mason. I am so happy with this tile.
Date published: 2012-02-28
Rated 2 out of 5 by from looks nice when it's done, but these stones were saw cut, not honed as the previous purchase. We needed one more set of stones to complete our project, but these stones were thicker than the previous ones, which causes a major difficulty attaining a uniform surface when some stones are already in place. Also, all previous stones were honed, these were simply cut. Fortunately we didn't need very many and therefore it didn't significantly affect the overall appearance. However, at the price we paid (same as honed), this was a disappointment. Since the stone were shipped in boxes of two sections each, why is it necessary to purchase 5 sections as a minimum???? Lastly, the coloration of the stone that we received was primarily gray, not as appealing as the previous stones. Please review the new supplier, if you have switched them; Home Depot is not receiving a "like product" but the retail remains the same. Not happy, but made due.
