Can I use Mapelastic AquaDefense membrane to bridge the gaps between cement boards?
It is important for cement board (and fiber cement board) to be installed in strict accordance with the written instructions of the board manufacturer. This typically includes taping the corners and seams with mesh tape and covering the tape with a polymer-modified, cement-based tile mortar. MAPEI's Mapelastic AquaDefense should not be used to replace this critical step or bridge the gaps between cement board.
