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.

Technical Specifications

Standard: ASTM C 309 type 1
Appearance: Marble liquid
Density: 1.05 to 1.10 g/cm³ at 25°C
Working temperature: Up to 70°C

1 litre of ADMIX CM491 covers 3-4 m², which forms a thin coat on concrete surfaces (10-15 microns). It acts as a primer for many subsequent surface finishes, unless those coatings and repair materials that rely on penetration for substrate bonding.

How to use
ADMIX CM491 is supplied as ready to use product. The ideal device for spraying uniform membrane is hand or electric power sprayers.

ADMIX CM491 is supplied in 20 L containers and 200 L drums.

This product should be stored in original containers under cover, out of direct sunlight and protect from extremes of temperature. Shelf life is 12 months.
