Applying Latex Paint Over Oil Paint

RE: Applying Latex Paint Over Oil Paint Post By steve (Guest Post) (10/28/2008) This is crazy. Latex paint was developed for going over old linseed oil paint. Latex paint needs a sanded, clean, and dry surface to bond to old linseed oil surfaces which you probably didn't have. Alaid oil is the modern version, which was developed to go over latex. The surface you had was probably moist. I know this because 90% of all paint problems are due to this. The rest is not sanding glossy surfaces. I've been painting for 17 years. If it is truly peeling 60 grit 80 grit then 120 hook and loop 5 hole sanding disks with a good orbital sander "porter cabel"a shop vac with dust attachment and hepa filter on your face to prevent lead poisoning of course. This will cost several thousand dollars to hire it out so get a painters manual. Like the "painters hand book", this will teach you the right way. DON"T rely on the internet for any advice all these ideas are stupid and dangerous enough to land you in the hospital. Believe me I've been there. Good luck.

How much of a problem will this be and what is the best way to proceed . Can we add another coat or should we struggle to remove both coats?

I sanded to get rid of the "loose" crackle. Re-textured used spray can texture, sealed with an oil based primer and then painted my latex paint over it (an off white) colored paint. This process worked well. I have no more crackling paint spot, however I now have what looks like a water stain spot on my ceiling where, for some reason, the paint did not take the same as on the rest of the ceiling. help what can I do to fix this it looks unsightly and it really bothers me!

The best thing to dc is rough it up with a palm sander of some sort, not a rough grit, but just something that will nock off what is loose and get rid of it. It will take longer, but it is worth the trouble, other wise u will have to do it again. Then I would suggest using oil based primer or kilz to prime the wall or whatever u are painting . then u can use either oil base or latex paint to add color. Oil based paint will not adhere to latex paint, as latex wont to oil based. Just like water and oil won't mix. To the person that said they were planning on painting window seals and baseboards with latex, please don't. it will be a heap of trouble. If u use latex paint, it will come off eaiser and won't seep into the wood. It also chips away easier in high traffic areas. Cabinets, trim, and seals need oil based paint. Latex paint in mainly for walls. Furniture also needs oil base if at all possible. Hope this helps!!

I recommend you do the physical work and sand off everything that is capable of coming off. If you can find one, use an old Green Black and Decker sander. They are fast and plaster does not bother these old sanders. Then, I recommend you use ordinary plaster mixed with ordinary white latex paint and apply a coat smoothly over the rough spots on your wall. Use a large trowel and after the plaster is dry on the wall, sand, sand and sand again until smooth to the touch! The next step is to use a "sealer" or "primer" and paint the wall completely. If you want perfection, sand again and apply more of the plaster/latex mix over any small imperfect spots you discover. One more time, use the sealer but this time, not over the whole wall, but simply over the small plastered spots. Now you are ready for two coats of color paint. Use a professional medium fibre roller and avoid drips. Good luck!

My suggestion is to explain your problem with the store you bought the paint from or contacting the paint manufacturer.

They currently have oil paint on them. Do I need to just use primer or do I have to sand as well (or is there an easier method)? Bettina from Atlanta, GA Answers: RE: Applying Latex Paint Over Oil Paint Oil produces a tough SLICK coating that would need sanding, UNLESS Lowe's painting dept. could recommend a bondable liquid that might be something like "liquid Sander". In any case, I'd also consider adding a quart of OIL paint to each gallon of Acrylic Latex, which sounds CRAZY, but actually is being recommended by some painters now. A helper accidentally did this when trying to surprise me by painting the inside of my garage years ago. It worked JUST FINE. Also, a big group of volunteers arrived to help me paint my home one year. They took all the various kinds of paint I had and mixed them ALTOGETHER in a 5 gallon bucket, and that formula of both kinds of paint has held better than any other paint I've ever had. These are both inside and outside examples of it working. So, make certian the surface is truly clean of wax, dust, dirt, stains, hair, etc., and I'd use plain ALCOHOL to clean the surfaces well, because there would be no need to rinse. THEN, I'd use the "liquid Sander" solution a little at a time, just ahead of my painting, following directions carefully, checking to see if it can be used with both kinds of paint. If you have the energy, it would be wise to go over all surfaces also with a med. grit sand paper MITT or special SPONGE made for such projects as curved edges, to scratch the finish for better adherence. Test an inconspicuous old painted area with the liquid sander first to see if it has no terribly ill effect on the old paint, but rather truly prepares the surface for bonding to new paint. Watch the timing recommended for applying paint while liquid sander is still wet, or for whatever it says. IMPORTANT: Use a very fine paint brush, and I prefer the flat hand held smooth velour brush/pad, with refills available, normally used only for finishing edges, which I use on most all surfaces very successfully because It both saves paint, and gives a very smooth finish if done right and evenly. Use a metal pie pan to fill the flat velour brush pad with a small amount of paint. Otherwise, you should buy the very best and finest bristle brush you can afford to get the best finish. If I had the money this is what I'd do. Good luck to you, and God bless and help you. : ) (06/15/2007) By Lynda RE: Applying Latex Paint Over Oil Paint I used a product called NO-Sand it is very nice just wipe it on and wait 10 min or so and then paint. It was a little smelly but it beat sanding. (06/18/2007) By Mary Ann Report Spam or Abuse
