Cement Additives


Permacem is a special hydraulic binder, which in combination with graded aggregates and water is used for preparing shrinkage compensated, fast setting high strength screeds, to create a base for laying of floor tiles, whether ceramic, wooden, linoleum, PVC etc ; carpeting or laying any other flooring system.

 Cement Additives


Permacem needs only addition of graded aggregates and recommended amount of water for preparing strong quick drying dependable mortar which is easy to mix and use.

Permacem is shrinkage compensated and hence there are no chances of shrinkage cracks. It is quick drying. Tiling mortars or self-leveling screeds can be laid within 3 to 4 hours of laying of Permacem screed.


SURFACE PREPARATION : Surface to receive Permacem screed should be sound, clean and free from any deleterious matter. It should be primed with water or SBR-OPC bonding slurry depending on whether it is an un-bonded or bonded screed

MIXING AND LAYING : Mix Permacem with graded sand of size 0-8 mm in the proportion of 1 : 6 by weight and add water at a dosage of about 35% by weight of Permacem in a mixer and immediately lay the screed mortar on the prepared surface and spread, level and compact it. For laying bonded screeds, first apply boning slurry prepared by mixing PERMA BOND SBR and OPC in the proportion of 1:1 by volume on the surface immediately before laying Permacem screed.
