Please would you recommend a marine two-pack epoxy anticorrosive primer to applied by airless spray onto black steel (I don’t think they can get pre-primed shot blasted steel), for a new canal boat. The boat will not usually be in salt water. Preferably Jotun. Many thanks Nick
Black steel normally means this is still covered in millscale which is very brittle and full of impurities.
We would not recommend painting over this as the coatting will fail.
Jotun Jotamastic 87 in black applied at 200 to 300 microns would be recommended for blasted steel.
