SURFIX SCA is a 1K acrylic rendering bonding agent that contains aggregates to improve mechanical adhesion on substrates especially on smooth surfaces. The fine aggregates are suspended in a special type of acrylic polymer and applied easily using brush or roller. SURFIX SCA reduces the porosity of the substrate and provides a mechanical key or adhesion from the fine aggregates suspended on the product. It is waterbased, non-toxic and ready to use.
