Rubber like Paint

[chas22]

I have a problem. We are removing the old wallpaper using DIF. The paper came off fine. After we removed all the paper we used the DIF to wash down the wall and remove any glue left. Then with an old washcloth and clean water we wiped the wall down. This has been 5 days ago. The wall now feels damp to the touch and the paint feels soft. In the places where the paint has peeled up it feels almost rubbery. Has anyone ran into this before and how do you fix it.

Any paste residual can make the wall feel damp ,relative humidity and temperature can have and effect on the drying process .Keep in mind that latex paint is porous and you have been dousing it with a liquid that is being absorbed through the paint into the paper face of the sheetrock or into the absorbent plaster.Check it for paste residual and remove with a minimal amount of warm water and a good clamshell synthetic sponge ,then dry with cotton terry cloth.Use fans and heaters to assist in drying with due diligence .Then scrape and or sand all loose paint using good pressure.I think this wall would be a prime canidate for Guardz or Draw-tite primer that will somewhat penetrate the latex paint and lock it down.After one coat of guardz patch the wall ,spot prime all patches with the guardz ,let that dry,then put another coat of the guardz or a pigmented wallpaper primer on the complete area allowing designated dry times between coats( a step that many rush)but important to adhere to if you want good results.Now you are ready to install.By the way it is not uncommon for latex paint to feel rubbery they are derived from similar substances.

Ditto on the suggestion of Zinnser's Guardz. It seals everything.:thumbup:

Hate to put the damper on such high aspirations about the DRC's, but it may be a tad unwise to build hope that Zinsser's Gardz (please note correct spellings) and Draw-Tite have a good chance of penetrating and locking down this paint. It's worth a test, but I would give it about a 25% chance of doing the trick.

Yes, Gardz and Draw-Tite will "seal" many things, but when the bond is poor to begin with, a coat of Gardz or Draw-Tite sitting on top won't improve the bond between the old paint and the wall.

BTW, to me, the old paint sounds like vinyl latex paint. I've know people who have wet it out thoroughly and scraped. A real pain, yes.

sorry for my view of reality.

But a good one, IMO.:thumbup:

I was, upon reflection, perhaps too confident in Guardz. Scraping that gooey mess off does sound like a lot of work but, may be the only way to deal with it. I have noticed, when doing removals, that, if the surface with residual paste is very wet and then rubbed hard or scoured with too much pressure, it will loosen the acrylic <primer or paint> on which the residual adhesive resides. Another option may be to put a fan on it and give it ample time to dry; then, scrape and sand or scrape, spackle, and sand to obtain a smooth surface. Then, apply the Guardz to encapsulte everything. I'd like to know what finally worked, please. Good luck!

The rubbery-feeling layer might be R-35.

Sounds like what you have is old PVA latex paint,with out a primer.and its lifting,back in the day that latex was garbage.the 100% acrilic is so much better.will stick to anything. i would sand with 180 and skim coat with durabond,then prime with drawtite or gardz.both very good products.
