I have a concrete slab floor with vinyl tiles on it. I want to use FLEXBOND to install ceramic tiles over the vinyl tiles on the floor. Is this a good choice or is something else better. Has anyone out there done what i want to do.
Asked by: Randy
I had black tar glued vinyl tiles on my basement concrete floor. I needed to level it in places and I used non modified thin set and self leveling cement. Nothing stuck to that black tar, so I decided to grind it off. I used 7" Makita grinder with dust cover and 7inch Dewalt diamond cup wheel. The grinder was attached to my large Ridgid shop vac. I successfully remover the tar and some imperfections but it took me long time. I had to cool down the wheel and the grinder for each 10 sq ft and dust off the filter for each 30-50 sqft. After the grinding any type of mortar or self leveling cement stuck to the concrete without any problems. I did not put concrete primer, I just poured water on concrete and spread it with a roller. My wheel is about 30% worn and I ground 500 sqft. Good luck. It is doable.

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 ...

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
