Premium Tile Adhesive
Type 1 is a premium-grade, traditional, nonflammable, acrylic adhesive for setting glazed and unglazed ceramic and porcelain tiles on walls, floors and countertops. This adhesive is used for interior applications only.
Is there a limit for the tile size?
The maximum size of a tile for use with Type 1™ is 6" x 6" (15 x 15 cm) on floors and 12" x 12" (30 x 30 cm) on walls.
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. Polymer-modified, cement-based mortars, such as MAPEI's Large Tile & Stone Mortar, are generally recommended for installing tile over radiant-heat systems. Refer to the written instructions of the radiant-heat manufacturer for recommendations of cement-based mortars.
Can Type 1™ mastic be used outside?
MAPEI's Type 1 should not be used for exterior installations. Polymer-modified, cement-based mortars generally recommended for installing tile outside include MAPEI's Large Tile & Stone Mortar and MAPEI's Uncoupling Membrane Mortar mixed with MAPEI's Polymer Additive.
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. If the cement-board manufacturer recommends a polymer-modified mortar, MAPEI recommends Porcelain Tile Mortar. If the cement-board manufacturer recommends a non-modified mortar, MAPEI recommends Uncoupling Membrane Mortar.
