Description
Prep Coat Primer
is a unique multipurpose 2-in-1 primer and waterproofing additive designed to boost adhesion, durability, and water resistance across a wide range of building applications. Used as a primer for membranes, it delivers excellent adhesion over general surfaces and dries fast, providing economical coverage of up to 1 litre per 8 m². As a waterproofing admixture, it improves the performance of cement-based compounds including mortars, slurries, grouts, and cement-based adhesives.
Ideal for porous substrates such as concrete, brick, and block work, this water-based, non-toxic, solvent-free formulation forms a high-quality bond to cement-based substrates and enhances the strength of the finished system. It is compatible with membranes, tile adhesives, renders, and water-based acrylic paints, making it a versatile choice for use as a paint and tile primer.
Engineered for areas exposed to moisture, weather, and immersion, and suitable over non-porous surfaces,
Prep Coat Primer
upgrades water-resistant and waterproof properties while enhancing bond strength. It also helps improve crack, frost, and salt resistance, offering enhanced durability with reduced shrinkage.
