Customer Questions & Answers

Can i use this stuff to install my mosaic kitchen backsplash.

Asked by: Vinnie
as always, read instructions on label. And ask your Home Depot tile person if this product will work on the "mosaic" tile that you choose. Size ,color and shape can make a difference in the mortar you use.

Is it good to use this to tape cement board

Asked by: kb123
This is what I used for smoothing a previous (sloppy) job. For the taped section, I moistened it very slightly and it worked fine. I only wish I had a "before" pix. Dries well, little to no cracking on thick spots.

How long before you can walk on it?

I realize it typically takes 24-72 hrs to dry and prior to grouting, but does that time frame still hold true for light traffic or walking on it?
Asked by: Firewire
I've been using this stuff for about seven years now and I've never walked on it. I don't think I ever will. If I were you, I would abandon the idea of using it for a floor and use real cement-based thinset, the stuff that has to be mixed out of a bag. I realize this is an inconvenience but the nature of this product as a mastic means it will never fully dry behind impervious tile and never reach the compressive strength of real thinset. It's never been worth the risk for me to use this on a floor. Even as a DIYer, I would instead chose Custom's Versabond for most floor tile applications. But, I'm not in your shoes, and the deed may already be done. I think you should probably wait at least 24 hours before taking a step on it, even if you live in an extremely dry area. The reason is, once again, the nature of the product. Most of it simply won't be exposed to the air when installed, and the areas that have very limited access to air will cure very, very slowly. How slowly? I've closed up a 3.5 gallon bucket of this and used it again eighteen months later.

Can I use this product to install glass wall tile over ceramic tile around top off tub surround ?

Asked by: Steve
You can probably get away with it. But still, this is the sort of thing experienced tilesetters would always use real cement-based mortar for. This is a convenience product and it has its uses. Custom is a great company, and I use their products all the time, but I would be hesitant about testing this product's limits. You'll find that everybody who's done tile for a while has some spectacular stories about mastic products like this one failing hideously in less-than-optimal conditions.

Wow, after reading several of the reviews, I am definitely in the minority here. I found this thin-set to be absolutely perfect for tiling my backsplash. The mortar stuck easily to the drywall. It was very sticky and held the tiles securely to the wall. I was using the glass and ceramic interlocking tiles. They didn't slide down at all once adhered and I found the mortar dried pretty quickly. I was in a pinch for time so I did not follow the instructions to give the tile 24 - 72 hours to dry before grouting. I finished the tiling at 10pm on a Saturday and Sunday morning I started grouting at 9am and had absolutely no problems with the tiles shifting or moving around. They were rock solid and I was extremely pleased with the final results of the job.

I used this to set 12 inch sheets of stone mosaic tiles that are 2 x 2 inches on a floor section. To my surprise and dismay, the mortar never dried. It's been 6 weeks or more. Now I'll have to remove and redo the whole job. I would never use this again.

Rated 4 out of 5 by from Works fine for me I have been building a new tub surround with 6in subway tile and glass mosaic and so far this product has worked well. I don't have a lot of experience tiling, but I'm about 40% complete and have not had any problems. I am taking my time so it's weeks, not days, so drying time hasn't been an issue. I had to take a few tiles off that I wasn't happy with, and I had a hard time with a pry bar and hammer getting the tiles off, so I trust they will stay put. It is thick and I had to practice to get to where I understood the best way to apply it.

Rated 1 out of 5 by from Horrible product!! I've done dozens of tile jobs and have always mixed my own thin set. This particular job was a small bathroom floor. Simple enough. I bought 2 gallons of this pre-mixed. First gallon went down thick and hard to evenly trowel, the second went down fairly smooth, better consistency. I let the thin set dry for 48 hours and the mix is still pliable. Never will I buy this stuff again. I'll just mix it myself and save some money as well.

Rated 1 out of 5 by from Horrible. Don't waste your money. Not at all suitable for a backsplash. It is too dry and therefore does not stick to the wall. I ended up with more on the floor than on the wall. I eventually gave up and yanked the tiles I had set off the wall. I'm going to try some of that adhesive tape stuff and see if it's any better. Will for sure be less mess. That's a bunch of money, time, and materials down the drain.

I tried to lay a fireplace hearth and surround. The horizontal hearth tiles never dried and the wall tiles 'slipped' after I removed the spacers. None of it dried, even after 4 days. Had to remove all tiles and broke one in the process. Does Home Depot actually test any of this stuff? Never again!

Rated 1 out of 5 by from Don't buy this stuff Watch this video before you do. I just wasted a day and a lot of money messing with this stuff. Ended up having to pull all the tile off of a bathroom install. One of the tiles fell damaging the tub, now I have to fix that. Spent the better part of a day trying to lay 12x24" marble tiles. The ads and pictures give you the impression that you can work it with a trowel just like thin set that you mix. You cannot. It is like sticking wet sand to the wall. As soon as you try to drag a notched trowel through it 1/3 falls off the wall in to the tub. Then you try to replace that third and another third falls off. After laying down 3 courses I was so frustrated I quit and went to dinner. We decided to pull everything down and start over with real thin set. When we pulled the tiles down you could see that about 1/2 did not have any of this stuff stuck to anywhere but the corners. Fortunately it just scrapes right off so I should be able to use the tiles again. I would really like to have my money back.

Rated 1 out of 5 by from Still Wet After 11 days. I've remodeled a lot of bathrooms and typically use bag thinset for floors. While installing I kinda like this product for walls because it has an adhesive quality to it. I had two gallons of this in my shop from a recent job. I poured the new shower mortar bed with bag mortar which was firm by the next morning. Then I spread a thin layer of premix to set the 2" tile on Friday the 11th. The next Monday I was surprised the tiles would move if stepped on. Today's the 22nd, I used plywood to distribute my weight while I tiled the walls, but the floor tiles still aren't set & the job is nearing completion. I can't grout the tiles if they are still moving and I'm not sure how long to wait and not sure how long this will hold up the job... and my pay. I will never use this product on a floor again, and will probably avoid it on walls since it took several days for the last backsplash to dry well enough for the spacers to be removed. lesson learned, the bag type is much cheaper and sets up quickly, making it a better product, so it's worth the mess and time of mixing myself.
