Mapecem Premix is a fast-setting, premixed cement-based mortar for concrete repairs and subfloor preparation work. Mixed exclusively with water, Mapecem Premix provides an easy-to-use, high-compressive-strength, fast-setting mortar that sets completely within 24 hours without shrinkage cracks. Thanks to MAPEI's High-Hydrated Cement Technology (HCT), Mapecem Premix offers superior drying-out characteristics for quick curing and does not contribute to efflorescence. When properly used, Mapecem Premix will allow installation of ceramic tile and natural-stone flooring after only 3 to 4 hours and installation of floor covering (such as vinyl, wood, rubber, linoleum and carpet) after 16 to 18 hours.

• Repairs concrete from 1/4" to 4" (6 mm to 10 cm) thick
• Allows tile setting in 3 to 4 hours
• Allows installation of floor covering in 16 to 18 hours
