Alpha Chem Concrete Hardener & Dustproofer hardens and seals the surface of concrete floors and provides a dust proof dressing that gives increased floor life.
Do not apply to non concrete surfaces. Surfaces should be free of loose particles and dust. Allow the new floor to cure before application for 28 days. Saturate surface and allow to dry for 24 hours. Avoid ponding of surfaces. After 1 – 2 hours, apply a second coat and wash excess material away to avoid a white deposit forming.
5 litres of the concrete hardener will cover approximately 20m² or, in general, use 5 – 10 litres per 100kg of cement.
Store in a cool, dry place. Containers should be tightly closed. Protect from frost.
