Concrete:
Surface must be carefully examined to make sure it is suitable and structurally sound base. Remove curing compound – form oil, salts laitance and other contaminants. Wash with multi-etch solution and thoroughly rinse with water. Concrete should be clean and dry before coating. Pinholes should be patched with H.D. Grout and Mortar or Epoxy non-shrink putty #69.
Steel:
Surface should be sand blasted to a commercial grade. When the surfaces are to be subjected to severe conditions, blasting to a near white grade as per S.S 2½ is recommended.
Mixing and Application:
Mix both components as per specified ratio until a homogenous mixture is obtained. It is very essential that component A and B are thoroughly mixed and that no traces of the components remain unmixed. Let stand for 5 – 10 min. induction time to allow bubbles to burst prior to application. EPOXY COAL TAR #300 may be applied by brush, roller and airless spray. Rate of application using airless is faster. It is important to apply in several coats instead of one thick coat prevent entrapment of bubbles.
