Exactly what surfaces can I spray your coatings on? Will it stick to wood and cement in addition to painted metal?
Since a polyurea, epoxy, polyurethane, or poly-hybrid can be applied to almost anything that can be otherwise painted, it’s easier to say what’s less advised (where it should not be applied). Those surfaces which are difficult to coat are chrome, galvanized metal, anti-stick plastics, or over any severe flaking corrosion or rust. Bare aluminum can sometimes be difficult as well (especially for polyurea coatings). For bare metal surfaces, scuffing plus suitable primer are recommended for best adhesion, and highly advised on some such as aluminum.
SL&C brand polyureas, poly hybrids, and epoxies may be applied to most other surface types with minimal surface preparation. For previously painted surfaces, generally just light scuffing will suffice. Concrete which is in a humid environment or below the surface can sometimes be difficult to coat with rapid curing polyurea such as our Rhino/Line-X Alternative Cartridge Products. For best adhesion, we recommend either our slower curing polyurea commercial product: Diamondback Linings DB-1081, or to first apply a coat of a quality 2 part epoxy primer first. Rapid curing polyureas can react to the moisture in some concrete structures and this can prevent good adhesion.
Wood is generally suitable to be coated with our products. The exceptions are usually if there are excessive areas of sap, undried wood which was recently treated, or large areas of wood fill which is not fully cured. New plywood or other wood structures may need to dry in the sun for a month or so before applying coatings of any type.
Always contact us first with any questions so we can properly advise to how to ensure the best results.
