Sealer - Barricade 50 Acrylic Sealer - 5 Gal -  A concentrated sealer for The Concrete Protector EXTERIOR cementitious texture systems. UV resistant gloss finish. This is a versatile 50% solids concentrated pure acrylic sealer that must be diluted first with solvent depending on state VOC laws: DMC (Dimethyl Carbonate) or Xylene. Typically diluted 1:1 with solvent to reduce the concentrate down to a 25% solids pure acrylic sealer. You may also dilute 2 parts solvent to 1 part concentrate (16.5% solids) and install 3 thin layers (depositing 50% solids on the surface).
