Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 is a two component, 100% solids epoxy resin system designed to bond new concrete to old and other materials to concrete. It has a convenient 2:1 mix ratio, by ASTM C-881-90, Types I, II, IV and V, Grade 2, Class "B" and "C" volume with a viscosity similar to heavyweight oil. Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 (adhesive) exceeds the requirements of ASTM C-881 Type II, Grade 2, Class "B" "C" "D" and E.
Epoxy.com Product #2007 is typically supplied and used in larger volume applications. As a practical matter, projects generally require a minimum of 30 gallons of material.
If your project is smaller than this, please contact Epoxy.com Technical Support for assistance in selecting a more appropriate product for your application.
Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 (adhesive) can be used for:
Bonding Agent
When Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 is used as an adhesive, bonding new concrete to existing surfaces, coat the existing area (concrete, steel, aluminum, wood) at a rate of 100 square feet per gallon (9 m2) on smooth surfaces, 60 square feet on rough (6 m2). Apply topping while Epoxy.com Product #2007 All Purpose Epoxy Bonding Agent (adhesive) is tacky; if dry, recoat.
Coating
When Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 is used as a protective coating, apply the material at a rate of 200 square feet per gallon per coat (8 mils) (19 m2/3.79 L -or- 5 m2/L).
Stir Component "B" thoroughly before combining with Component "A". Combine 2 parts volume of Component "A" with 1 part by volume of Component "B" for not less than (3) three minutes, using a slow-speed drill motor (300 to 600 rpm) and Epoxy.com Mixing Paddle for a uniform gray mixture. Scrape sides and bottom. Avoid entrapping air in mixture. Apply immediately after mixing to properly prepared surface.
Surface must be clean and sound. Remove rust, grease and curing compounds by best means available. Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 may be applied to dry or damp surfaces, but not in standing water. Apply by brush, roller or spray. Place fresh concrete while Epoxy Fresh Concrete to Hardened Concrete Adhesive #2007 (adhesive) is still tacky. If epoxy hardens simply apply another coat.
