Reply With QuoteI believe if it is acrylic and you wipe it with metho then some of the color will come of on the rag, enamel wont.

How to identify oil paint? I am repainting all my architraves and need to know of the previous paint is oil based.
If it is oil based paint then I need to sand and prime. If it is water based, then I only need to lightly sand to take off the gloss.
The exsiting paint is glossy, but I don't know how to tell whether it is oil based or not.
So, how do I tell if something has been painted using oil based paint?
I'm no expert, but know enough to be dangerous...

Dear Gooner,
Droog's method of detecting Acrylic is the probably the only thing you can do, because I've never heard of a way of detecting Enamel (as in Oil-Based...).
Two things worth adding though:
1) If she happens to be peeling anywhere (like a thick brittle peel), you can be fairly sure it's Enamel.
2) Use a dark-coloured cloth when you're rubbing the Metho on for the Acrylic-test.
Good Luck,
Batpig.
Thanks for the suggestion. I grabbed a pair of the Mrs old black underwear and tried it out. Small white stain after rubbing it with metho on the architraves so I assume acrylic.
(hmmm.. white stains on the Mrs underwear.. I'm sure there's a joke in that somewhere.)

Was the white stain paint or the black colouring of the material bleaching out?
