Questions & Answers

whatis the mixture ratio, water to flex bond thin set, 50 lb. bag for proper mixture for application

cannot find this anywhere
Asked by: Bob
I never mix a full 50 lb bag at once so I carefully weigh out smaller amounts from 10 - 20 lbs. Instructions work out to 3.2 oz per lb . I start at a rate of 3.5 oz /lb to get it less stiff, (or almost 10% more), and its still plenty firm. I'll splash in a little more, but at this point you must be careful to not overdo it ( hopefully you have extra powder if you do)

Can this be used to set 12" x 12" porcelain tile on 5/8" gypsum board to be used directly behind wood burning stove as a heat shield separated from the wall by 1" spacers? The temperature has gotten as high as 180 degrees back there
Asked by: Chica
The paper layer on gypsum will not stand the moister needed to apply the tile and most drywall is not a suitable backer for tile sorry

FlexBond White 50 lb. Crack Prevention Mortar is rated 4.6 out of 5 by 130.

It is a great product that adheres well to tile and to substrate. The problem you will have, if you live in a warm climate, the stuff will set up WAY too fast. I had started a project with Laticrete CJ Multi. I mixed up a 50 pound bag and it went fine. I was about 1/2 the way through so I figured I'd use the Flexbond. After about 30 minutes the stuff was getting very hard to use. I had to add a little extra water and remix. This happened two more times over the next 20 minutes. I couldn't add any more water so I had to throw away at least half a bags worth of mixed thinset. If you are going to use this stuff, make sure you use ice cold water to mix it. Even then I would recommend not trying to use the mixed thinset in temperatures above 75 degrees Fahrenheit. Unless you are a crazy fast tiler and you have all your tiles pre-cut, don't mix up the entire 50 pounds at once. You'll end up throwing a lot away along with your money. Consider this a cross between a quick set thinset and a normal thinset. For me, it was crap.

For the past 10 years, I have used this product exclusively for setting tile. The additives for crack protection are outstanding. The product itself is relatively expensive, but I have received ZERO callbacks for loose tiles since using this product. That has value beyond just financially. Do it right and forget it; this product does just that.

The associate who kindly helped me with the return, Sheila, could feel the lumps through the packaging. From my many experiences at Home Depot, I know that this was an anomaly.
