No. Not all white, milky polymers are created equal. There are many different chemistries resulting in many different properties of the polymer. For GFRC, it is recommended to use an acrylic-based polymer, with all-acrylic providing the best performance. Many concrete polymers and bonding agents on the market should be avoided in GFRC. SBR’s are not UV stabile and will yellow over time. PVA’s will hydrolyze when wet, becoming water soluble. Only Forton® VF-774, an all acrylic co-polymer, was developed specifically for GFRC.
