Can I paint over bronze coloured aluminium windows and doors with white gloss? E Nolan
Yes, but you need a special primer to make the paint stick to the aluminium and the natural colour beading on same. I’d suggest something like ESP, which works very well on shiny surfaces to give paint a grip.
After you apply the ESP (as usual read instructions carefully) it would also be a good idea to use a high quality oil based undercoat and top coat. We always recommend that you do a test piece somewhere inconspicuous first to get the feel of it etc. (Not the front door!)
For the best possible result, add about 25% Owatrol oil, a paint conditioner into the first coat (undercoat) or even first coat of two coats of gloss, and about 10 to 15% (just enough to make it “flow nicely”) to your second coat for a superb finish. You should end up with a lovely brush mark-free, rich finish that will last for years. ESP & Owatrol are available on our website and the better paint outlets.
