How should Mapeheat Membrane be installed into the subfloor assembly below the floor coverings?

Installation of Mapeheat Membrane below luxury vinyl flooring follows the same installation method as engineered and laminate floors: First, embed the floor-heating system within cementitious material, ensuring in 1/4" (6 mm) of coverage above the heating system. Either a mortar or self-leveling compound can be used, but achieving the desired flatness is easiest with a self-leveling underlayment. Proceed with installing the floor covering on top, following the manufacturer’s instructions.

I don’t like the color of my grout. How can I make it look like it’s supposed to, or do I need to replace it?

Replacing grout is certainly one way to fix the problem. Instead, use UltraCare Grout Refresh, a water-based color seal, available in 40 standard grout colors. It’s made for refreshing the look of old, discolored grout, or completely changing the color of the existing grout. Don’t replace it, Grout Refresh it!

Is UltraCare Grout MAXimizer the same as using a sealer?

UltraCare Grout MAXimizer is not a sealer. It is a polymer additive, formulated specifically for use in standard cement-based grout mixtures to fortify the grout and help resist staining caused by water borne contaminants. Some premium sealers repel both water and oil-based staining.
