Anvil #1750 High Performance Water Borne Grip-Tite Bonding Primer applied directly to clean porous concrete overcomes the problem of improperly prepared surfaces prior to painting or staining. Grip-Tite penetrates into the concrete and improves the adhesion of the topcoat. Grip-Tite forms a surface that improves the workability and durability of the topcoat. #1750 Grip-Tite is a specially formulated bonding primer that can be used to improve the bonding whenever a masonry type coating, such as Anvil # 1700 High Performance Epoxy Show Coat Concrete & Garage Floor Paint, Anvil #1500 Water Reducible Acrylic Solid Color Concrete Stain or Anvil #2300 Semi-Transparent Concrete Stain is to be applied. Anvil #1750 High Performance Water Borne Grip-Tite Bonding Primer can be used interior/exterior, painted or unpainted, vertical/horizontal concrete, masonry, stucco, CMU block and porous brick surfaces. Also great for use as a touch up primer where other surface coatings have failed. Do not use on wood, metal, epoxy/urethane or silicone treated surfaces.
