I am trying to paint and the old latex paint is peeling off what looks to be a plaster oil based paint.?

Any tips on what I should do to prepare to prime and paint?





Thanks a bumch!I am trying to paint and the old latex paint is peeling off what looks to be a plaster oil based paint.?
go to the paint store and buy ';Paso';. It'll cut the grease, grime, etc., that causes the latex not to adhere to the oil base. You can first get a 120 grit sand paper and sand first, just a swipe or two, then clean it with the paso on an old rag. Just pour some on a rag and wipe. Be sure and let that rag air out fully so you don't burn your house down by putting it in the trashcan. Believe it or not, it will self combust if not carefully disposed of. Be sure that if you have any pilot lights, to temporarily turn the gas off until you can air the fumes out of the house. It is kinda strong, but it works. Then you can re-light the pilot lights. Ask the people at the paint store, they'll be able to help. It'd be better if you go to a real paint store, and forego the heartache of the big home improvement store amatuers (store names withheld for legal recourse purposes).I am trying to paint and the old latex paint is peeling off what looks to be a plaster oil based paint.?
Typically you can not apply latex paint directly over oil based paint. The oil based paint is too slick for latex to adhere. Prime the oil based paint with KILZ, then apply the latex paint.
Welcome to my world.


First you need to peel the paint. I find that it is very relaxing especially after a bad day at work. Once you have all the peeling paint removed, You can lightly sand and prime with a really good primer.


If you have one in the area, go to a store that sells nothing but paint, they'll be able to recommend one.


Good luck
As a painter, been there done that. Unfortunately, there are no easy remedies to your situation. You first have to scrape all of the loose paint off. What starts as a small area will often end up covering a large area. the good news is that the paint generally scrapes off easily. Once you have an area where the entire edge is soundly adhered, you have to prep the oil based paint that is now exposed so that new primer will stick. first clean it, then either sand it, or use liquid sand paper/deglosser. Once prepped use a bonding primer on the exposed oil based paint. You can feather the edges of the newer paint, but I prefer to blend the edge with setting type drywall compound. This type of drywall compound is tough to sand, so make it as smooth as you can with your drywall knife. Sand it even smoother when dry, then prime the entire wall with a quality water based primer, and paint. FYI, I like to use the 90 minute setting compound.
Two words~strip %26amp; sand
hi, first scape any and ALL areas of loose paint.now use a product called ONE TIME.you can find this at most hardware stores.it dryes fast and sands easy.use it where ever there is a edge.using a 6in drywall knife ,spread the One Time ,following the paint edges as smooth as you can .this will feather out and take away blemishes.now with mesh type (fine) sand paper lightly sand all mudded areas.the One Time is low shrinking,but may need a 2nd coat.if so apply 2nd coat let dry and resand.yes,you can use the 90 min type setting that Kirk wrote about ,but the One Time don't have to be mixed.if you do use 90 get the e-z sand in the (blue and white)bag. now you need to use a special primer that will allow your color coat to adhere.i would use Zinnzar-Bulls Eye 123 or Kiltz.they both work well.the Kiltz is a little more smelly.this is important,because it's what will make your next coat stay on.you can see the blemishes better after this step,so if you need to ,you can touch up one more time. but if you do then you need to reprime those areas over again.now your ready to put on top coat. good luck.
