Rated 4.7 out of 5 by 83 reviewers.
Rated 5.0 out of 5.0 by 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. January 15, 2015
Rated 5.0 out of 5.0 by Easy install of a beautiful new bathroom Easy to mix and held tile in place very well on floor and on walls. We are not professional tile setters - just a working couple taking on a bathroom renovation by ourselves. The end result is beautiful and, most importantly, we're still talking to each other!

Rated 5.0 out of 5.0 by Great product! This thin-set worked great for our tile project. We used the orange plastic product for underlayment and everything was beautiful! March 12, 2015
Rated 5.0 out of 5.0 by Love Versabond. Pretty much every tile I install I can use this product I install a lot of tile and use Versabond for most of my applications. I like the ease of use and long working time. I would recommend this product. February 17, 2015
Rated 5.0 out of 5.0 by Shower renovation This thinset help me create this gorgeous shower. All work was done by me with Home Depot products, which helped me turn a closet into what you see here February 4, 2014
Rated 5.0 out of 5.0 by Good Purchase Purchased 26 bags to install tile in my home. Great product! May 19, 2015
Rated 4.0 out of 5.0 by Does the Job I used this product in conjunction with DITRA Mat. It was a very successful installation. If you're not used to mixing mortar, I'd recommend starting with half the recommended water and working your way up from there to reach your desired consistency. I'd also recommend an electric mixer be used, unless you have a strong and tireless person nearby. April 29, 2014
