windows stick when i paint with laytex
i am a homeowner, not a professional anything.
in the past when we have painted windows with latex, the surfaces have stuck where 2 latex finishes touched– even after several weeks of drying before the windows were re-installed.
what am i doing wrong?
thanks

I usually top coat with satin polyurethane to prevent this. For me this has been a long time issue.
The new latex paints never dry to a hard surface like alkyds. For this and other reasons, in exterior applications, they also "attract" dirt and dust that can't be completely washed away, even with scrubbing. Latex paints have some advantages, but these are a couple of the disadvantages.
I wouldn't coat them with polyurethane as Condoman suggests. You're likely to have all sorts of problems. Do a Google search. "latex over polyurethane".
I'm just throwing out here for you to research.... What about shellac. It is a sealer that is compatible with every finish and is used extensively in woodworking. It dries quickly by solvent (alcohol) evaporation although most pre-mixed shellacs contain methyl alcohol that has been slightly diluted with water to make it less expensive. A little 0000 steel wool will give it a satin finish.
There are some paints (typically the pricier options) that our more resistant to staying tacky. A good paint supplier can advise. Also, never paint the tracks, seals etc on windows. Those are meant to be dry and do not work properly when painted. With old weight style windows I never paint the jamb where the window sash needs to slide unless requested. The paint usually rubs off in those areas anyways. I always advise customers of the likelihood that windows will stick if jambs are painted, some demand it anyways. If you need to paint the jambs, use a color match in flat paint. Coat the jamb in paraffin or a dry silicone for less friction.
I'm wondering if some sort of wax could be used to coat the edges that come into contact with each other?
thanks for your suggestions.
what about using alkyds on the windows with latex where 2 surfaces do not touch?
thanks again.
Google is your friend.
i talk to google more times a day than my other friends.
Insert a doubled layer of wax paper in the joint when you close the window.
oops. i just noticed that i misspelled latex. my bad.
