CEKOL Quartz Sand Wall Primer (5KG)

CEKOL GS-83 CONTACT is a high-performance quartz sand primer designed to strengthen surfaces and enhance the adhesion of plasters, putties, and mortars. This non-toxic, non-flammable product is perfect for both interior and exterior applications, providing a rough, durable surface that improves the uniformity, setting, and adhesion of subsequent coatings. After drying, it forms a resilient layer that resists water and alkaline agents while allowing water vapor and gases to pass through, ensuring the surface remains breathable.
