Product Information
Pyrahard Colloidal Densifier – High-Performance, Budget-Friendly Concrete Densifier
Pyrahard Colloidal Densifier is a professional-grade concrete densifier designed for contractors and operators who want reliable performance at a competitive price point. Made in Australia, Pyrahard uses the latest colloidal silica technology to penetrate deeper, cure faster, and deliver a harder, more durable concrete surface.
Formulated with ultra-small particle sizes and advanced additives, Pyrahard achieves superior penetration into the pores of concrete, creating strong CSH (calcium silicate hydrate) hydrogel structures that increase surface hardness and density. This makes it a versatile solution for:
- Concrete polishing | Ideal for both early grinding stages (after 80–100 grit) and later stages (after 400 grit polishing pad).
- Anti-dusting and curing | Retains moisture in freshly poured concrete for a stronger cure and a dust-free finish.
- Primer/moisture barrier | Reduces water evaporation and supports faster installation of coatings or floor coverings.
With its low, non-caustic pH and zero VOC formulation, Pyrahard is safe to use indoors or outdoors and won’t break down under UV exposure. It’s the perfect balance of performance and value for those who want a dependable, easy-to-use colloidal densifier without stretching the budget.
Key Benefits:
- Advanced colloidal silica formula for deeper penetration and long-lasting durability
- Smaller particle size than standard silicates – improved bonding and harder finish
- Safer application – low pH, water-based, and environmentally friendly
- Versatile use – ideal for polishing, curing, and as a moisture barrier
-
Made in Australia – quality you can trust at a competitive price
