    Default paint not adhering to trim

    Hi Everyone,

    I have been slowly replacing the trim in my dated 1900s home. I've been using pre-primed wood casing around the windows. Today, I painted some of it and where the angled cuts were made at the corners, the paint won't adhere. It looks similar to the way water looks on a freshly waxed car. Any idea why its doing this?

    thanks!

    Huberm,

    Did you use anything to fill the seams at the mitered joints? If so what?

    Yes, I used white caulk to fill the seams. It said on the caulk tube that it was paintable - do you think this is the issue?

    Bet you used silicon based caulk.........

    Just use "painters latex" caulk.

    Huberm,

    True silicon caulks are not paintable. There are "siliconized" caulks such as DAP's Alex Plus which are paintable.
    The fact that it is peeling only at the seams where you spread this caulk would indicated that in spite of what the label said, it was not. At this point, I would throughly sand the areas which are peeling and try re-priming and painting.
