Painting Over Other Antifoulants
Although Awlstar Gold Label will work over some existing antifoulings, Awlgrip cannot endorse this practice. We have no control over other antifouling manufacturers' quality control or formulation. Awlstar Gold Label will not perform over any of the tincopolymer/organotin antifoulings, soft conventional types or vinyls.
Awlstar Gold Label will perform adequately over hard conventional type antifoulings and tin-free ablative copolymer antifoulings that contain copper. The most common problem encountered with these applications is mudcracking. A test application should be made before recoating an entire hull unless all other antifoulant is removed.
Do not apply primers over old antifouling paints. If the test application indicates a compatible situation, sand the surface with 80 grit then apply 3 coats of Awlstar Gold Label.
Use antifouling paints safely. Always read the label and product information before use.
