Repairing door jambs
« on: August 28, 2018, 09:08 AM »
Hello, we are replacing the doors in our house and our jambs need some work. They were painted white at some point, but also left with what looks like the original finish. The white will chip off as seen in the picture (sort of). We want the jambs white. Any tips on getting a nice white finish on the jambs?284524-0

You could send them down, use a nice primer, sand again, prime again, sand lightly, finish coat 1, sand lightly and then last coat of finish.  I would try to use a BM Satin Impervo (WB) (there are many reviews on other paints - Pro Classic, PPG, etc).

It looks to me like when the jambs were painted, the jambs weren't sanded or they weren't cleaned or both. A good sanding, some primer and 2 top coats should fix that.

It seems like you're asking two questions.  Correct me if I'm misunderstanding.
1.  How to deal with the chipped paint.  I don't see primer under that chipped paint.  I wonder if they painted right over the wood?  Anyway, scrap away anything remotely loose.  Sometimes you can't tell until you run a scraper over the paint and suddenly paint you thought was adhered just breaks off.  So scrap every inch of those jambs.  Sand, prime, light sand, paint x 2 (as mentioned above).

2.  The stained part of the jamb needs to be painted white.  Use a shellac based primer (stir well before use) to cover up the brown.  2 coats to be safe, sand, paint x 2.

I won't tell you which paint to use, but I will say I've not been happy using Sherwin's new Emerald Urethane trim paint.  It just doesn't level well (or at all it seems).  I suspect a pro painter would find a way to work with it, but I tried with and without Floetrol, good brushes, mohair rollers, foam rollers.  With Floetrol and a roller worked the best, but I won't be using this on trim because it's not leveling well.

scrape, use spackle or another filler to even the paint out sand smooth check to see if it needs more repeat , prime and paint.

Pry the door stops off, sand the frame and stops then reattach and paint.

That's some junk paint that's on there if it just flakes off indoors without any weather influences. Normaly you only see this outside where paint is exposed to heavy rain and the burning sun.

Find out if it's only this spot that's flaking or if the entire layer of paint is loose. Use a putty knife or chisel to see how easily you can scrape it away. If it's just this spot than there's not so much to worry about, but if the entire layer is so badly adhered you'll have to remove it entirely.

I picked away a little bit yesterday. The white stuff will probably come off pretty easy once I start. It’s just the corners where it meets the stops that will be tricky, I guess that anyone might take them off. I’ll see how it goes without that. Shellac primer will go on the non painted parts. Thanks.
