GAF Metal Primer is effective in providing corrosion protection, flash rust resistance, and enhanced adhesion over steel, aluminum, and galvanized metal surfaces.
GAF Metal Primer can be used over new or unpainted wood, where it is effective at blocking tannin bleed-through. It is also effective at locking down residual chalkiness on previously painted exterior surfaces. Over concrete and masonry substrates, it provides alkali resistance.
