Exterior Insulation Finishing System (EIFS), also known as External Thermal Insulation Composite Systems (ETICS), is a multi-layered cladding system that provides insulation and waterproof surface for exterior walls to improve the insulation effect of buildings. EIFS is composed of a heat insulation board as the primary material made of expanded polystyrene or mineral wool. It also contains an adhesive for bonding the insulating board to the substrate. It is then covered with a cement base coat with woven glass fiber reinforcement and a textured colored finish coat.

Viscelo products can effectively improve the water retention,open time,sag resistance,workability of the ETIS/ETICS mortars.
