Can this product be used to install the large tile directly to the basement floor? My home is about 70 years old, and the basement floor is fairly level, and I don't believe there are any cracks. Would this product work?

Answer: 
It should have a smooth yet thick consistency. It should not be runny. Extra moisture in your mix means you will have longer cure times and greater shrinkage. Thick like creamy peanut butter is best. Don't mix more than you can use in an hour. It is always better to mix more as needed than try to revive a set up batch.

Answer: 
There's a lot of talk about proper mortar consistency in the tiling industry because it's hard to describe. The two most common ways of describing the correct texture is to say it's like peanut butter or stale frosting. Neither are particularly accurate, because I've never seen either peanut butter or frosting that weighs as much as mortar or that has sand in it.

There's a lot of talk about proper mortar consistency in the tiling industry because it's hard to describe. The two most common ways of describing the correct texture is to say it's like peanut butter or stale frosting. Neither are particularly accurate, because I've never seen either peanut butter or frosting that weighs as much as mortar or that has sand in it.
The best advice I can give you to is follow the directions exactly when it comes to the proportions and time spent mixing. For many years, many mortar mixtures responded to dramatically to changes in relative humidity and temperature. People mixing thinset prided themselves on not needing to follow proportions or measurements printed on the bag, because achieving the correct consistency always meant deviating from them.
Over time, advances in the profession have led to better polymer-modified mortars that are much more humidity-stable and temperature-stable. With the introduction of medium-bed mortars like this one, the importance of mixing according to the given proportions and times and not "winging it" has become even more important, as technical papers notes that many mixers-by-eye tend to thin out these mortar mixes too much when they make up a batch.
Since you are probably going to be storing and using this mortar indoors, with the heat or A/C on, follow the proportions and mixing times written on the bag. If you are mixing any sort of significant amount, use a machine mixer attached to a drill. Run the drill at a painfully slow speed and keep the head submerged in the mix.
The given proportion on the bag is 6 quarts of water per 50 pounds of dry mix. Six quarts of water weigh 12.52 pounds. 50/12.52 = 3.993... So, if you weigh your water and your mix, you're looking at an almost exact ratio of 1:4 by weight for any amount of this stuff.
Set up your measured water in the bucket and put your respirator on. Dump the dry mortar in slowly. Put your drill with mixer attachment in and begin mixing. If you're used to baking, the consistency will seem horribly off for a batter, far too dry. Mortar isn't flour. Keep mixing. After three minutes or so, you'll get a smooth consistency and again, if you're used to baking, you will see stiff peaks form in the mix. Patiently mix until that happens, and then mix a bit more, and then stop. Set up a kitchen or microwave timer for 5 minutes. When the time goes off, mix again for a minute. Clean your tools.
If you follow the same procedure methodically every time, you'll follow it even when you're tired, and that will go a long way to helping you mix up consistent mortar batches during a demanding day's work.
Good luck! Nothing beats this stuff for getting the job done with natural stone in difficult situations. Read Less

Rated 4.6 out of 5 by 49 reviewers.
Rated 5.0 out of 5.0 by Lovin' It ! I'm building a new home and needed mortar for the slate that we needed to lay under the fireplace and by the front door. This product was so easy to use and the tile looks fabulous. Home Depot has been so easy to work with as I am navigating this project, from help and suggestions to dealing with my returns - thanks guys! September 13, 2016
Rated 5.0 out of 5.0 by First time laying tile with mortar for natural stone First time laying tile with natural stone. Mortar works great, easy to use for a beginner. July 20, 2016
Rated 4.0 out of 5.0 by Tile Mortar I bought this as recommended by Home Depot for my product. The first batch mixed very thick and was hard to work with. I was working with a light colored tile and could not see easily any mortar on the top of the tiles until it dried and hardened. Clean up was difficult. I found that the cheaper grey mortar that was not recommended was listed as suitable for the tiles I used. The grey mixed well and applied well. Clean up against the light colored tiles were easier. So far, the grey is bonded just as good as the white. September 16, 2016
Rated 5.0 out of 5.0 by Worked very well I used to install 2x4" travetine back splash with spots of 8 1x1 accent tiles. Worked well. Used 1/8" wedge spacers along bottom and between tile mats to keep from sliding down wall and maintain 1/16" tile spacing. Note this setting compound is for large tiles and any size stone tiles. Since had only about 20sf made 1/4 bag and did bottom mats 12" high. Let set for at least an hour and made second batch and layed therest. This was only my second tile project. Recommed watching utube videos on laying tile if novice like me. September 20, 2016
Rated 5.0 out of 5.0 by Good product My experience is similar to Builder's. If you're not working quickly, the mortar will begin to skin over, at which point newly laid tile won't stick. If you find this happening, simply scrape up the skinned-over mortar, put it back in the mortar bucket, and mix it around some more. I did all my tile cuts before mixing any mortar. This significantly reduced the amount of time for actual tile installation. I was able to complete a 27 square foot bathroom space in about 3 hours with large format tiles. This being my first tile job ever, I'm happy with the results. July 29, 2016

Rated 4.0 out of 5.0 by good for large tile, holds profile if mixed properly will skin over if not quick to lay tile, so don't doddle. June 7, 2016
