Admix CM491
Emulsion Resin Based Concrete Curing Membrane
ADMIX CM491 is based on emulsion resins which form a non-soluble film after drying. Selected resins in the formulation have excellent intermolecular bonds as well as good adhesion to dry and wet concrete surfaces. The product retains sufficient moisture in the concrete to ensure full hydration of the cement. This product contains no hazardous solvent or dangerous materials, so it is ideal to be used in closed areas such as tunnels.
Application Method
ADMIX CM491 should be sprayed on fresh concrete before drying. The ideal time of application is when the concrete surface does not shine anymore (Max. 20 minutes after placing process). The application can be done by spraying a thin layer on surfaces exposed to atmospheric conditions. In case of very drying concrete surfaces, wet it with water thoroughly before applying curing membrane.
