BDC Concrete retarder is a light green mixture of chemical solutions which react with cement on the surface and retards the set surface layer to a depth of between 3mm and 12mm while the underlying concrete sets. This enables the concrete surface to be removed easily, often by brushing or water blasting, and exposes the aggregate to give the depth of the etch to the concrete. 20mpa +
BDC concrete retarder is ready to use product, do not dilute. Always wash tools and equipment with warm water after use. 4-6 sqm per litre.
