Customer Questions & Answers

Gray or White?

This mortar comes in gray or white. Can anyone explain to me why you would use one color over the other? Thank you,
Asked by: ImBlue
the gray is as its natural color, whereas the white is bleached (not like the table top bleach, just the process) which makes it cost a tad bit more. the white is recommend for your glass and light colored mosaics and tile. pretty much, If you are using any light colored tile OR grout, you want to use the white. if you use the gray, you are running the risk of the grey bleeding through the tile and grout

Is this good for use on 12"x24" ceramic tile on a shower wall over hardie board?

I am not sure if I should use adhesive or thinset on the shower walls.
Asked by: Sparky
DO NOT USE ADHESIVE!!!!! Only use Thinset on any tile unless you are doing a backsplash or something small. Mastic or Adhesive will fail, especially in a wet area. Your better option would be the Versabond LFT because your tile has a side longer than 15". The LFT will be stiffer thus supplying more grip and stick when you put it on the wall. Also please make sure you waterproof your shower. Just using hardie board is not the way to go. Check out the waterproofing systems and follow instructions to a T. It's worth the small investment and time vs having to rip it all out and start from scratch. Check out the JohnBridge dot com website as well. There is a ton of great info on everything related to tiling that you could ever need to know.

Will this work good to thinset my cement board to the subfloor?

Asked by: Brock
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.

Can it be apply directly over Durock cement board to cover an outdoor kitchen with veneer stone

Asked by: FamiliaD4
Yes and cement board is the best surface for adhesion to tile over

Make sure to only add enough water for a thick pancake batter consistency though, otherwise it runs into the grout lines and can be difficult to clean out later.

It seems to work with clay tile. I am replacing three rooms of tile due to lack of adhesion to porcelain tile ON RADIANT Heated floors. Expansion/movement due to floor heat, seems to break the bond. It did work well with clay tile. I have since found a Home depot product FOR porcelain tiles, which we will see what happens next heating season.

I would have returned the bag but my tile guy didn't tell me until the job was done and I was expectiing there to be at least a half bag left to do a small table project. Quality check.

I mixed about 1/3 at a time which gave me about 45 minutes to work with each batch. Consistency of product is uniform and high quality. A good experience using VersaBond. Now I need Bengay for the soreness of making a brick wall my age!

Rated 5 out of 5 by from Tile and thinset tips and tricks I’ve used this thinset for years on different projects and have had very good success with it. It is easy to mix and spreads well when applying it. I use this thinset for both tile work as well as a jointer for hardie backer. Long term, this thinset holds up quite well and provides an excellent bond. Your tiles will feel stable and secure and won’t break loose over time. I’ve learned a few tricks on the best way to work with this stuff and I hope this helps you on your next tile project. Get the mix right. What you want is a consistency similar to peanut butter. I use a 5 gallon bucket to mix this in. I’ll pour however much mix into the bucket as I think I’ll need for the work I’m doing over the next hour or so. This is usually about ½ a bucket of thinset mix or less. Use your garden hose to add some water to the mix. Be careful not to add too much. Typically, you want just under 1/3 as much water. Use a paddle mixer and drill to get things going. Don’t spin the drill too fast either, just keep it slow and steady until the water is all mixed in and the thinset mix is nice and smooth. The consistency needs to be such that you can spread it easily on a surface and the troweled ridges will continue to stand up on their own. It still needs to be pliable enough though to maneuver the tile in place. While setting tile, if the thinset mix starts to dry out, you can always add just a bit more water and re-mix it to get it back to the right consistency. Don’t apply too much thinset at once. Remember that this stuff will start to dry out once you spread it, so don’t apply more that you can work in about 20 minutes. Twist the tile just ever so slightly when setting it. This will help to get the bond right. I also use a rubber mallet to tap the edges of the tile to ensure I get a good bond. You may also need the mallet to work on getting the corner heights to match up. Remember that setting tile isn’t just the square and making sure the grout lines are straight. You also have to make sure the tile lays flat and the set height is even with the surrounding tiles. I tend to use tile spacers to line up my spacing. Have a large putty knife handy as well as the trowel. I use a 4” putty knife probably more than the notched trowel itself. This is handy for cleaning up tile edges, “buttering” the backs of tiles (when you get into those corners) and scraping up unused thinset off the floor. A hammer and cold chisel works well for getting up dried thinset off the floor. Sometimes at the end of a long day, you may forget to clean an area of thinset off the floor at the edge of a tile you just laid. This will dry and in the morning you’ll have to get it up before you can lay more tile there. Not to worry, just take a hammer and cold chisel to it and it will come right up.

Rated 5 out of 5 by from Easy to Use So, a couple of do-it-yourself tile books I have talk about thinset in almost mystical terms as how hard it is to mix, get the consistency right, and have good adhesion. I poked around the net, and found someone who measured out a 50# bag of versabond, cup by cup. The magic ratio is 11 cups thinset to 4 cups water. I used this ratio, and my very first batch was absolutely perfect. I was laying 16" tiles, so I could put down about 6 tiles (I was using a 1/4 x 3/8 notched trowel) before I had to mix more. The key was that the troweled peaks did not sag, nor were they gritty (too much water, too little, respectively). I checked adhesion and it was fantastic. If you follow the mix ratio above, you get slightly less than 1 gallon of thinset. I was able to easily mix this in a plastic pail with an 18V Dewalt. I have also used the pre-mix thinset, but wanted to try the Versabond because it is so much less expensive. I'm glad I did. The picture below is Montagna Cortina, carried by Home Depot, along with Hardiebacker. Over the past few years, I've completed two baths, a backsplash, and some decorative tiling with this combination.
