Answer: 
Since ceramic is opaque, we use gray and for porcelain we use white because some porcelains are translucent enough that the gray can show through enough to darken it slightly.

Answer: 
As I understand it, the only time you'd normally use the white thinset (which costs a little bit more) is if you are using a translucent tile or mosaic, or if you are planning to use a white or very light colored grout.

Answer: 
Depends on what you are using it for, we use it to install dry stack granite tile, so there is no grout, we use gray for most installations, but for lighter stones we use the white so if some does show through it isn't as visible

Answer: 
Ususally installers use white mortar when setting light color tile or stone or when grouting with light color grouts. Darker tile use gray mortar, lighter tile use white mortar. On grouting sometimes when you miss a spot when cleaning the edge of the tile, the white thinset won't be as noticeable at gray mortar will.

Answer: 
Yes, if your tile is larger than 12 x 12 I recommend a large format mortar on top of the backer board. This mortar is fine for under the backer board. Use a 1/4 x 1/4 trowel and set backer board on wet mortar.

Wow! That's a really interesting question. While I'll say right up front that I don't know for sure what the manufacturer's answer would be (and in such cases I always recommend that you contact them), I do have some thoughts on the issue that I'm willing to share with you.
My first involves the presumption that you are not putting your tile down over a concrete subfloor; rather, your subfloor is either wood of some sort (plywood, particle board, planks, or even hardwood) or some type of vinyl or other such floor covering. In such cases you normally screw your cement underlayment directly to the subfloor placing the screws where indicated on the underlayment itself. Since the underlayment is fastened securely to the subfloor and the tile rests on thinset that rests on the underlayment, the presumption is that all of the materials, subfloor, existing floor, underlayment, thinset, and tile will form a relatively stable mass, resistant to shifting and cracking. This thinset, used in this manner, should be more than adequate for that purpose.
However, if your subfloor itself is uneven or unstable, screwing the underlayment directly to it might not give satisfactory results and you might be tempted to use the thinset as a self-leveling cement on which you would lay your underlayment, employing the mastic properties of the thinset instead of screws to hold the underlayment in place, then using the thinset to cement the tiles in place. If this is what you envision, it seems your underlaynent could work much the same as an anti-fracture mat, maybe even better!
The one problem I see with this approach is that this thinset, however versatile and great for its intended uses it may be, is not really intended to substitute for self-leveling cement which has much greater compressive strength and can be successfully used in thinner layers without the cracking and eventual disintegration that might be experienced with the use of the thinset for this purpose.
So, if this comes close to describing your situation, while I do like the idea of employing the underlayment as a type of antifracture mat--especially where the subfloor is so dissimilar to the material of the flooring on top of it--I'd be hesitant to recommend using the thinset itself to remove any unevenness in the floor. In any event, touch base with the manufacturer before you commit to any such course of action. Read Less

i would not
the adhesive quality of the versabound is for cement to tile
the tile would be to smooth to make good adhesion
i like the versa bound as it makes good adhesion to correct substrates
one of the good qualties is clean up of frot of tiles is easy
but this would work against adhesion to smoth non pose tile
i have made the test chambers for mabe to test just this thing

Rated 4.0 out of 5.0 by Rust-o-leum Concrete Sealer & waterproofing We build a waterfall /pond and we thought of applying the Rust-o-leum waterproofer. The product is easy to apply, worked well in sealing fine lines and reduced water evaporation. It has been almost a year and still worked great. I highly recommend the product. June 14, 2016

Rated 4.0 out of 5.0 by Good thin-set mortar. This thin-set mortar is a quality mortar and fairly easy to use. However, it does have a fairly short set time so you need to install your tile quickly. Also, I highly recommend that you remove all excess mortar from between your tile prior to it completely drying as it is much harder to remove once it has fully set. I use a painters knife to remove the excess mortar and quickly wipe the tile edges with a paper towel. This leaves a clean groove for installing your grout once the mortar has completely cured.

Rated 5.0 out of 5.0 by Worth the extra money I'm using this to lay backer board and tile in a couple bathrooms. I also tried the, much cheaper, non-modified thinset and found that this stuff is worth the extra cost. The non-modified didn't go on as smooth and dried way to fast for my liking. I am not a seasoned tile installer, so I'm a bit slow, but I like having the extra time to position tiles correctly. I used the gray (which really dries a tan color) because is more closely matches my grout color. If you're using white grout, get the white version of this thinset. That way any particles of thinset that make their way into your grout wont' be as noticible. June 28, 2016
