Flowcrete Isocrete PHS

Flowcrete PHS (Penetrating Hardening System) is an ultra-low viscosity, solvent-free liquid designed to refurbish and re-strengthen failed cement and sand screeds. Rather than removing and replacing a defective screed — a costly and disruptive process — PHS penetrates deep into the substrate, filling voids and bonding material together to restore the screed to a very high strength finish. With an overnight cure time and a dust-free installation process, it is the ideal solution for refurbishment programmes where time, budget and minimal disruption to occupants are all critical factors. Installed by approved applicators only, PHS is guaranteed to meet BRE Test Category A requirements for 15 years.

Benefits

• Penetrates and re-strengthens failed sand:cement screeds without the need for removal
• Ultra-low viscosity for deep penetration into voids and defective substrate
• Overnight cure — dramatically reduces overall programme time
• Dust-free installation with no disruption or damage to surrounding finishes
• Impermeable to water once cured
• Significantly exceeds BS8204 BRE Test Category A requirements for floor screeds
• Guaranteed to BRE Test Category A requirement for 15 years
• Solvent-free and low odour — safer for occupied or sensitive environments
