Flexybo Concrete & GFRC Acrylic Polymer Curing Aid, Fortifier & Primer

  Flexybo Concrete & GFRC Acrylic Polymer Curing Aid, Fortifier & Primer Flexybo is 100% acrylic.  49% solids. Acrylic Polymer is a MUST for any GFRC mix. Without it, GFRC work must cure for 7 days in a climate controlled environment with over 95% humidity! Flexybo is also a must to use on any old concrete surface prior to applying a new overlay or microtopping.  It will seal the substrate, preventing water loss and any resulting shrinkage in the underlayment or overlayment.  It will greatly improve the bond and flexural strengths which will increase long-term durability. When used as a primer, 1 gallon provides up to 500 sq ft surface priming coverage! Adding Polymer to GFRC and Concrete mixes speeds up cure time, in some instances to just 24 hours, so you can demold your concrete piece very quickly. Add to concrete mixes to reduce shrinkage and increase bonding and strength. Polymer works by 'holding' the water in the cement, not allowing it to surface during curing. This sp
