Rovene 403 can be used as a polymer modifier for hydraulic cementitious mixtures for repair, basecoats for EIFS, decorative overlays and tile grouts or mortars requiring low odor during application. Addition of 5 - 15% (d/d Portland cement) improves flexibility, strength and water resistance.
Rovene 403 in portland cement mixtures results in increased adhesion to most substrates, improved water resistance, increased flexural strength and good resistance to UV light. Rovene 403 does not contain antifoam. The addition of an effective antifoam is generally required to avoid a high air content in the hydraulic cementitious mixture. Many antifoam products have been found effective at levels of 2.5% wet on wet by mass.
