Products / IB Rust Primer

IB Rust Primer is a water-based, modified acrylic rust-inhibiting primer applied over metal roof substrates to slow corrosion and improve the bond of the IB acrylic or silicone finish coat. It is light gray and sold in 5-gallon pails and 55-gallon drums. The TDS gives a coverage rate of 0.5 to 0.75 gallons per 100 square feet (8 to 12 wet mils) per pass, a minimum dry film thickness of 4 mils, a VOC content of 66 g/L and a recoat time of 1 to 2 hours at 70 F and 45 percent relative humidity. For new galvanized or Galvalume steel and non-ferrous metals the TDS directs IB Uni-Prime instead.
