As part of renovating my master bedroom, I’ve stripped and primed all the trim. However, after a month or two the previous finish is telegraphing through giving a yellowish tint.
Under the old paint there is a clear finish which I believe is causing the problem. The paint is no problem for the Citristrip, but the clear finish ends up quite sticky and takes days to dry even after a good wipe down with mineral spirits. I used Kilz oil based primer.
At this point, I’m afraid to continue with paint. Do I have to start over? What else can I do (or should I have done) to prevent this? Am I using the wrong products?
Signed,
Tired of stripping.

Just out of curiosity how old is the house?
1870-1880's...
learn to use a good sharp scraper and to keep it sharp. The citristrip does not need to take it off, just to soften it to make your work easier.
BTW, primer will yellow after two months anyways, no matter what is under it, but make absolutely sure the stripper is rinsed/removed from the wood surface.

Try using some denatured alcohol (along with #000 or #0000 steel wool) instead of the MS for the wipe down/removal of the soft underlying clear finish. Keep it wet for a couple minutes. It's probably shellac and MS won't be effective on that.
As already mentioned, today's "oil" primers (actually alkyd primer) will yellow after a while.
If you're waiting a month or two after priming before getting the topcoat on.... you've already lost the advantage that the primer offers for good topcoat bonding.
Yup, I'd bet the farm it is shellac. Take it all off and apply new shellac.If the OP doesn't want that, then I'd suggest priming with a coat of white pigmented shellac, first, then the regular primer and top coats.
Hi BryanSayer,
What's your reasoning for a coat of pigmented shellac and THEN primer?
g
Shellac is a good barrier coat and will prevent resins and such from bleeding through.
I agree, but shellac does not have that great of tooth, hence the second coat of primer.
It will be okay, just go over it with a fresh coat of kilz before painting. Also, a light going over with a fine grit sanding sponge will before the paint will give you a really smooth finish.
Are you using oil paint? I like to use a satin finish oil on trim, like Satin Impervo (Benjamin Moore).

I thought BM Impervo was only an interior formula.

The master bedroom is usually interior.
That's okay Piffin, we all miss the nail occasionally. ;)--------------------------------------------------------

Thanks, everyone...all good advise. Of course I always use a sharp scraper, but I am definitely going to try the denatured alcohol. I will probably use an oil (alkyd) paint.
