How do you prepare metal for epoxy?
Before applying epoxy, sand smooth non-porous surfaces—thoroughly abrade the surface. 80-grit aluminum oxide paper will provide a good texture for the epoxy to “key” into. Be sure the surface to be bonded is solid. Remove any flaking, chalking, blistering, or old coating before sanding.
What do you put on bare metal before primer?
To properly prepare new metal surfaces, use mineral spirits to remove grease and apply a rust-inhibitive primer before painting. For painted surfaces that are in sound condition, remove dust with a clean, dry cloth, de-gloss the surface with light sanding, and wipe with mineral spirits to ensure good adhesion.
How do you clean bare metal before primer?
The first step in painting metal is to thoroughly clean it. The metal might look and feel clean, but any grease, oil, dirt, or rust left on there will prevent the paint from properly adhering to the surface. Avoid using water to clean metal; instead, use a solvent such as acetone.
Is epoxy primer good on bare metal?
Both Epoxy Primer and Self-Etch primer (Self-Etching primer ) can be used on bare metal. Both provide corrosion protection, and both can be top-coated with primer surfacer.
What is the strongest epoxy for metal?

Does epoxy work on metal?

What is the best primer to use on bare metal?

Self etching primer bonds well to bare metal surfaces and can be top coated in a short period of time. Epoxy primer can be applied in heavy coats which can be guide coated and block sanded to remove small imperfections in the body. Epoxy primer takes longer to dry (cure) before it can be sanded or top coated.
Do I need etch primer on bare metal?
Self etch primer (was) recommended for bare steel, aluminium or GRP, and it won’t flake off like a filler primer can. Paint tends to run when applied directly to bare metal (even more so when bare metal is mixed with a plentiful quantity of body filler – runs start at the interface between the filler and paint).
