Can I use a quality oil based dark grey undercoat as a finish for exterior use? I like the dry colour and the sheen finish from this paint. Cheers.
Best to use primer first then exterior paint never use primer for final finish recipe for disaster
If you use an exterior sealer on top - but it will require regular maintenance , as all external paintwork.
I personally wouldn't leave and exterior oil based undercoat exposed to the elements. Oil based paints provide several finishes, eggshell/satin/gloss
Absolutely! Yes you can. Just ensure that substrate is well prepped, especially no residual emulsion paint underneath, and apply two coats. You can thin the 1st coat 5% with white spirits
There is external undercoat on the market and at most diy stores I wouldn't advise using any internal paint outdoors.
Hi i would not use an oil base undercoat as a finish if you want the look i would suggest using a satin wood in the finish of the undercoat.
you can but make sure it's exterior paint
No it won't last ,there are eggshell type finishes available
