RETARDE M is a solvent based paint-like liquid which when applied to formwork or moulds, prevents concrete poured against it from setting for up to 72 hours. This allows the retarded concrete to be removed by hose after the formwork has been stripped, resulting in an exposed aggregate finish.

USES

RETARDE M is used to create a mechanical key on a concrete surface which is to have more concrete poured against it. An example of this is where RETARDÉ M is painted on stop ends which confine individual pours of a floor slab. When the stop ends are removed and the retarded concrete is washed off, the resultant exposed aggregate finish makes an excellent key for the next pour.
RETARDE M can also be used to create an architectural exposed aggregate finish on columns, beams, panels, pavers and any other formed concrete surface.
