COPROX Cement Additive – 5KG is a high-performance waterproofing admixture designed to be added directly to cement mixtures to enhance water resistance, strength, and durability. It effectively waterproofs cement-based applications by reducing porosity and increasing density, forming an integral barrier against moisture penetration.
This additive is widely used in plaster, screeds, concrete, and mortar to improve bonding, workability, and resistance to dampness, efflorescence, and cracking. When mixed with cement, COPROX Cement Additive chemically reacts to seal capillaries and micro-cracks, providing long-lasting protection from both positive (external) and negative (internal) water pressure.
Key Features & Benefits:
-
Integral Waterproofing Protection: Permanently waterproofs cementitious materials from within by sealing pores and capillaries.
-
Improves Durability: Increases strength, flexibility, and resistance to cracking and surface degradation.
-
Enhances Workability: Provides a smoother, creamier texture for easier mixing and application.
-
Prevents Dampness & Efflorescence: Reduces water absorption and stops salt formation on finished surfaces.
-
Multi-Purpose Use: Suitable for concrete, plaster, mortar, screeds, and renders.
-
UV & Weather Resistant: Ensures long-term protection in both interior and exterior environments.
-
Eco-Friendly & Non-Toxic: Free from harmful chemicals, making it safe for use in residential, commercial, and water-retaining structures.
