Special fast setting hydraulic binder for the preparation of normal setting and fast drying (4 days) screeds with controlled shrinkage.
Formation of floating and bonded screeds on existing and new slabs for the installation of wood, ceramic tiles, natural stone or any other flooring where fast drying is required for short installation times. Suitable for interior and exterior use.
Topcem, mixed with graded aggregates and water, hardens within 24 hours and is completely dry within 4 days.
Bonded screeds and patching (less than 35 mm thicknesses) first require the application of a Topcem and Planicrete anchoring slurry. For floating screeds (thicknesses above 35 mm) lay a polyethylene sheet beforehand.
Recommended mixture ratio: 200-250 kg of Topcem with 1 m3 aggregates (0 to 8 mm diameter) and with 120-140 kg of water for dry aggregates.
Open time of the mixture: 40-60 minutes.
Set to light foot traffic: after 12 hours.
Waiting time before installation: 24 hours for ceramic tiles and 2 days for natural stone.
Residual moisture after 4 days: less than 2%.
Storage: 12 months.
2-2.5 kg/m2 per cm of thickness.
20 kg bags.
