Topcem Premix is a ready-to-use mortar suitable for interior and exterior
applications, bonded as well as unbonded. It has an accelerated set, allowing
for installation of ceramic flooring in 1 day after placement, and nonbreathable
flooring systems in 3 days. Topcem Premix can easily be screeded or sloped,
and has the workability and working time of conventional screed mortars with a
much faster setting time. It is ideal for interior or exterior repairs such as filling
trenches, re-sloping balconies, and forming screeds that may or may not receive
subsequent flooring installations
