Can I use Type 1™ mastic with a radiant-heat flooring system?
MAPEI's Type 1 should not be used with radiant-heat flooring systems.

Refer to the written instructions of the radiant-heat manufacturer for recommendations of cement-based mortars.
Can Type 1™ mastic be used outside?

Can Type 1™ mastic be used in a pool?
MAPEI's Type 1 should not be used in any exterior application, including submerged installations such as swimming pools. Use MAPEI's Adesilex™ P10 Mosaic & Glass Tile Mortar mixed with MAPEI's Polymer Additive.
Can Type 1™ mastic also be used as a grout?
MAPEI's Type 1 should not be used as grout. For convenience, MAPEI offers MAPEI Flexcolor® CQ, which is a ready-to-use (premixed) grout.
Can Type 1™ mastic be used under cement board?
MAPEI's Type 1 should not be used under cement board. Refer to the cement-board manufacturer's written installation instructions for cement-based mortar recommendations.
