DESCRIPTION: Special fast-setting hydraulic binder for the preparation of rapid setting and drying (24 hours) screeds with controlled shrinkage.
APPLICATIONS: Formation of floating and bonded screeds on both existing and new slabs for the installation of ceramic tiles, stone material, wood or any other flooring where rapid drying and immediate relaying is required. Mapecem must always be mixed with graded aggregates. Bonded screeds (less than 35 mm thickness) and patching first require the application of a Mapecem and Planicrete anchoring slurry. For floating screeds (at least 35 mm thick) lay a polyethylene sheet beforehand and use aggregates being graded from 0 to 8 mm in diameter.
TECHNICAL DATA: Recommended mixture ratio: 350-450 kg of Mapecem with 1 m3 aggregates (0 to 8 mm diameter) and with 80-160 kg of water depending on the aggregate moisture. Open time of the mixture: 20-30 minutes. Set to light foot traffic: after 2-3 hours. Waiting time before installation: 3 hours for ceramic tiles and natural stone. Residual moisture after 24 hours: less than 2%. Storage: 12 months.
