TRUBUILD PS PRIMESURE PRIMER is a single-component, ready-to-use, water-based acrylic primer specially developed to improve substrate preparation before applying waterproofing membranes and protective coatings. It is formulated with acrylic emulsion polymers, selected fillers, and performance additives that provide strong adhesion, pore sealing, and improved surface penetration. The primer creates a uniform base layer that enhances the bonding and long-term performance of subsequent waterproofing systems on both interior and exterior applications.

The product is designed to prepare porous construction surfaces by reducing surface absorption, sealing micro pores, and improving coating efficiency. It can be applied on plastered walls, brick masonry, concrete surfaces, false ceilings, asbestos sheets, and similar substrates prior to water-based waterproofing or finishing coats.
