APPLICATION
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.
COVERAGE RATES
5 litres of the concrete hardener will cover approximately 20m² or, in general, use 5 – 10 litres per 100kg of cement.
STORAGE
Store in a cool, dry place. Containers should be tightly closed. Protect from frost.
