covering material

• For substrates with an MVER exceeding 5 lbs. per 1,000 sq. ft. (2,27 kg

) per 24 hours, using a calcium chloride test (reference ASTM

F1869), install a suitable MAPEI moisture-reduction barrier.

• Make sure the substrate and ambient room temperatures are between

50°F and 95°F (10°C and 35°C) before application. Temperatures

For professional use only: Self-Leveler Plus may be extended with 1/4" to 3/8" (6 to 10 mm) of clean, saturated surface-dry (SSD) aggregate on the primed surface at no more than half of the total pour depth. Pour Self-Leveler Plus over placed aggregate and rake aggressively to ensure full contact and bond with the substrate. Immediately pour 1/4" (6 mm) of Self-Leveler Plus over the raked aggregate to provide a smooth, level surface.
