Mapei Mapecem Premix Series 2060021 Screed Mortar, White, Powder, 50 lb, Bag

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 hr without shrinkage cracks. Thanks to Mapei's High-Hydrated Cement Technology (HCT), Mapecem Premix offers great 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 hr and installation of floor covering after 16 to 18 hr.
