ProKa

Liquid Additive for Renders

KÖSTER ProKa is a liquid, ready to use additive for render, mortar and screed to increase workability. Traditional mortars for rendering include lime to ensure good adhesion to the substrate and increased workability. But the presence of lime also reduces the strength and the water resistance of the mortar. KÖSTER Proka solves this issue by ensuring good adhesion together with improved workability of the mortar, without the addition of lime.

• It is used in cement based mortars instead of lime,
• Interior and exterior renders and mortars,
• For masonry and brick laying mortars,
• Can be used in floor leveling screeds.
