Painting Aluminium panels before signwriting

As Khriss says.....

It's the same as Landrover Panels...etch primer chemically bonds to the aluminium so that paint can then bond to the primer. If you don't regular paint just peels off.

As Bob_z_l and others have said, you need etch primer. The surface of aluminium quickly oxidises to produce a surface to which paint won't adhere. In olden-times they wire brushed the surface to remove oxides and then painted it quickly before more could form.

You must use an air-fed mask, especially when spraying 2-pack etch primer. If it contains iso-cyanate, the clue is in the last part of the name! Etch primer contains an acid which (naturally enough!) etches into the surface of the aluminium, allowing paint to 'stick'.

You can buy brush-paintable etch primer but you surely wouldn't have a surface that was smooth enough for sign-writing, would you?

>>>ALSO I want to hire a firewood processor and operator within reach of woodland at WR6 6JG. Any suggestions? I may consider buying a processor at the right price.

Many thanks, Lindsay Porter

Cheers, it looks like you have had sign writing printed onto boards still. I was hoping to sign write directly onto the sides...
