PRODUCT APPLICATION
PRODUCT APPLICATION
Read all installation instructions thoroughly before installation. -Apply Mapesonic RM when substrate and ambient temperatures are between 40°F and 95°F (4°C and 35°C).
ADHESIVE
Apply Mapesonic RM when substrate and ambient temperatures are between 40°F and 95°F (4°C and 35°C).
MOTAR
Lay the pre-cut Mapesonic RM into the mortar or adhesive.
FOR CERAMIC/PORCELAIN TILE INSTALLATIONS
Apply Ultrabond ECO ® 420 to the substrate and allow it to become tacky. Use a 3/32" x 3/32" x 3/32" (2.5 x 2.5 x 2.5 mm) V-notch trowel. Or, alternately, apply a MAPEI mortar meeting the ANSI A118.15 industry standard, such as Ultraflex ® LFT™, Ultraflex LFT Rapid or MAPEI Ultralite ® Mortar, using a 1/4" x 3/8" x 1/4" (6 x 10 x 6 mm) square-notch trowel.
FOR WOOD-FLOORING INSTALLATIONS
Apply any MAPEI urethane wood-flooring adhesive to the substrate with a 1/8" x 1/8" x 1/8" (3 x 3 x 3 mm) U-notch trowel and use the wet-lay method.
FOR VINYL OR CARPET TILE INSTALLATIONS
See chart below for suitable adhesives. Apply the selected adhesive per the adhesive’s Technical Data Sheet (TDS) method for bonding to a nonporous substrate. Use a 1/16" x 1/16" x 1/16" (1.5 x 1.5 x 1.5 mm) square-notch trowel. Allow the adhesive to flash off and become tacky. Use the wet-lay method if using MAPEI’s Ultrabond ® G15, Ultrabond G19 or Ultrabond G21 adhesive.
