Elakor-PU Siler-B — concrete curing compound without solvent odour
One-component polyurethane impregnation for curing fresh concrete and topping without solvent odour, works in frost down to −10 °C.

This epoxy pore-filling primer contains not more than 8 % solvent and is suitable for almost any building substrate: concrete from M150, sand concrete, cement self-levelling floors, wood and plastic. It is applied by roller, brush or trowel in 1–2 coats until the surface looks like wet concrete under epoxy and polyurethane coatings, and mixed with sand it is used for filling. The pot life of the mix is at least 40 minutes, application at +5…+25 °C; according to the technical data sheet, the primer is permitted at food and pharmaceutical plants.
