Reinforced quartz hardener

REFLOOR® CT-S500

Reinforced quartz hardener with a higher share of coarse mineral fraction, for intensive wheeled traffic and abrasion.

95 MPaCompressive strength

0.08 g/cm²Abrasion (LKI-3M)

25 kg/mm²Impact resistance

Where to use

Warehouses and logistics centres

Regular traffic of warehouse equipment.

Production areas

Intensive wheeled traffic, abrasive dirt.

High-traffic car parks

Driveways and ramps.

Not suitable

For old hardened concrete. A dry-shake hardener is applied only to freshly placed concrete.

System

A dry-shake hardener reaches its strength only with proper curing.

Apply REFLOOR® AC-S200 curing & sealing compound right after final troweling: it cuts moisture loss of fresh concrete by 90%, reduces dusting and improves oil resistance. Economy option — AC-S120.
