    Either would work - be sure to use a good primer first like Kilz.

  • I've used latex after glazing windows with no problems.

    You will have better adhesion and durability with oil. Make sure you clean them good first and let them fully dry before priming. I prefer Kilz.

    thank you everyone. I would like to clarify that Kilz primer an oil primer you can latex over, per the Kilz rep.

    thanks again!

    Glazing means glass. So are you painting the glass or the wood framing? I have to correct Frances, you can put latex over oil but not oil over latex. I would always prefer to use oil esp outside but since I don't know if you are painting the glass or the wood, kind of confused since either of those paints while working on glass would not last long outside.

    im using the term glazing for the stuff you place over the points that hold the glass in place. It’s put on at an angle and barely covers any of the window glass. You’ll notice it on all older windows. My house 1923.

      Nice work on stripping off the old paint on your windows. I am restoring a 1926 home and I used an exterior primer by Zinsser and it is latex so easier clean up. Then I used Behr exterior semi gloss for the top coat which was two thin coats so I didn't obscure any of the crisp detail that I just took forever to uncover. Good luck. Oh by the way I think you have to wait a month to paint over the glazing. I painted everything and then glazed and then just painted the glazing the next spring using a small flat artist brush that was 1 inch wide. The brush allowed me to apply the paint but also keep a sharp paint line so there was no scraping off of excess paint after the paint died. I don't know which task is more tedious.....applying the glazing compound or painting the glazing. Good luck with your windows.

    I’ve got a 1952 built house, when re doing the glazing, you want the glazing at a 45 degree angle between wood and glass. The 45 angle lets the water ie rain shed off, if the wood is really dry, mineral oil let it soak in then glaze the widows. A 5 in one painters blade is the only tool you will need, besides your fingers, and a ladder.
