PRO CEMIX is a polymer-modified fast-setting, pre-blended, calcium aluminate cement-based mortar bed and screed mix designed for concrete repair and for building new screeds. When mixed exclusively with water, this mortar provides a high compressive strength, shrinkage-free screed with a residual moisture content of less than 2.5% after 24 hours. PRO CEMIX is also used to repair concrete holes and fill trenches up to 10 cm (4″) deep; slope shower pans from 10 mm (3/8″) up to 50 mm (2″) thick; and build new mortar beds up to 50 mm (2″) thick. PRO CEMIX allows foot traffic and ceramic tile installation after 3 hours and floor covering installation after 24 hours making it an ideal product for quick turn-around projects such as retail and commercial centers, hospitals, airports and manufacturing plants.
