Can Mapeguard 2 be used as a waterproofer, as well as for sound control and for uncoupling?

Yes, it can be used for sound reduction, crack isolation, waterproofing and vapor management. However, when using Mapeguard 2 for vapor management, do not use MAPEI SM Primer or MAPEI SM Primer Fast; instead, use MAPEI HM Primer. If there are seams, the use of Mapetape BB tape is also necessary for waterproofing and vapor management.

Can I use Mapeguard 2 over oriented strand board (OSB)?

Yes, with these limitations: Tile must be installed per installation standards published in the most current TCNA Handbook, ANSI 108 specification. If the OSB is weather-beaten or delaminated, it must be properly overlaid with a cement backer unit or an additional layer of subfloor.

Can I use Ultracolor Plus FA with glass tile?

Yes, but keep in mind Ultracolor Plus FA has fine sand in it, so you may want to perform a mockup first to make sure it doesn’t scratch the tile.
