ER Systems® Acrylic Metal Rust Primer is a modified acrylic waterborne primer serving multiple purposes.

Features:

• Great adhesion and corrosion resistance
• Air dry
• May be used as a primer and as a finish coat
• Superior re-coat ability and exterior durability

Uses:

Acrylic Metal Rust Primer may be applied over marginally prepared metal surfaces such as galvanized sheet metal, structural steel, steel decking, aluminum and over concrete. More is not better in the case of Acrylic Metal Rust Primer.

Application:

Recommended application on smooth surfaces is to spray apply in one wet full coat to a wet film thickness of 6 - 8 wet mils (1/3 - 1/2 gallon per square). A "tack" coat is not recommended. This should be followed by a spray applied full wet coat. On porous or very rough surfaces, it may be beneficial to backroll or brush a first coat to work the primer into the surface with mechanical action. Alternatively, rough or porous surfaces can be given two wet full coats by spray at 1/3 gallon per square each.
