Acryl Pro is used to put Ceramic tile down, not vinyl tile. If you already have Ceramic tile on the floor, it has to be smooth before you can put down the vinyl tile. If you have any bumps or dips, it will show up after you walk on it for a while. If it is smooth, Henry's makes a vinyl tile prep that you put down on the floor to help hold the tile down better. You can find it at Lowe's. If you have bumps and dips, you will have to either pull up the old Ceramic and start over, or put down a new subfloor.Im putting down self adhesive vinyl floor tile.....????????
the first thing you should do is make sure your floor is smooth, by smooth i mean filling all the grout lines in the ceramic tile. the self stick tiles will sink into any places that there is an indentation. i would NOT recommend doing what you are. the only way i MIGHT do this would be to glue, using lots of liquid nails, new laun over the tile then apply the self-stick tile
as long as the surface is smooth yes. there is stuff that you can spread out to smooth the cracks or places where tile may be missing.
I think ACE is telling you to hedge your bets. The adhesive on the back of floor tile is sensitive to heat, cold, and moisture. Using an additional adhesive should resolve that problem by providing more stick um.
