How not to have weatherstrip stick to painted doors?

by Joe Gemmill

After carefully prepping, sanding, and applying two coats of pricey semi-gloss latex with a smooth surface roller, I have a beautiful front door, almost looking like it was sprayed on. Having removed the old aluminum and grey rubber weather strip, I let it dry for a WEEK at mid-sixties temps, with NO weatherstrip. I install the NEW weatherstrip, (aluminium with a soft grey synthetic rubber bulb seal on the exterior of the door jamb). Two days later, I open the door and paint has stuck to to the weatherstrip. (Gack!) I am thinking WD-40 or spray silicone dry lube on the weather strip might prevent that. Any clues from my fellow DIY'ers? Thanks!

    Joe, that is easy: Apply invisible tape or painters tape onto the door underneath where you want to put the insulation tape. By that, you are not applying the insulation tape directly to the door but instead applying the insulation tape to something removable but firm.

    You can also tape cloth strips to the door too, as something to apply to.

    Did you prime the door before painting? Sounds like a lack of primer issue

    talcum/baby powder/corn starch on both pieces, should last awhile, then repeat,take a few times til it stops; it's got something to do with the plastics(PVA and PMMA) the latex paint is made with. Anyway it worked on mine,along with the everyday dust in the desert where I live.

    First clean the rubber with Goo Gone then coat it with WD40.

      I tried your suggestion, knowing WD-40 has silicone in it and hit the rubber gasket with a quick spray of silicone, too. Film at 11. Ha! Thanks!
