Tile over Painted Lightweight Cement
The Lowes contracted installer put an item on the estimate called "Red Guard" and listed it as an anti crack product.
In the estimate, they also stated that they would be removing the existing paint/sealant from the Gypcrete surface. So my questions are:
A. Is Red Guard as good a solution as the Noble CIS for this application? Is it something that is simply painted onto the surface?
B. Is he right or wrong in thinking to remove the sealant/paint from the Gypcrete first before the Red Guard is applied, or does it go over what's already there?
C. How will this product impact the future of the floor, in case something else wants to be done with it by possible future owners?
D. Will removing the sealant paint for any reason reduce the life of the floor (even with the Red Guard over it? When I read about the Noble CIS it seemed like it would go down on top of the sealant layer that's already there)
Thanks again people, I really appreciate the info,
