RETARDÉ M & MX Paint-On Formwork Retarders


RETARDÉ M is a solvent-based, paint-like concrete retarder applied to formwork that reacts with fresh concrete to create exposed aggregate for construction joints, etc. Won’t run from formwork, resistant to light rain. Retards concrete for up to 72 hours after pouring.

RETARDÉ MX is a water-based, spray on concrete formwork retarder.

Both products are used to create a mechanical key on a concrete surface which is to have more concrete poured against it.
For example, 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. RETARDÉ M & MX can also be used to create an architectural exposed aggregate finish on columns, beams, panels, pavers and other formed concrete surfaces.
