Interior blistering painting help needed.......

[basswipe]

Once the paper came off and the glue was removed alot of times you still have to "neutralize" the walls.1:3 vinegar/water.Then really let it dry I mean for a couple of days.

Before you do anything else prime it with an oil base primer like Kilz or CoverStain.Then do your mudding and sanding then give it a full prime again.Then hit it with your finish.

Older plaster like horsehair and calcimine can cause blistering too if the surface isn't prepared properly.

Unfortunately you're now in a position where you've done a lot of work to it that its now going to be that much harder to fix it.Using the vinegar/water mix may not work to well now.You may have to look into specialized primers that are alkali resistant.BennyMoore makes one as does Pittsburg.

If you get the walls back to the point more or less to right after you stripped the paper and glue I would try the dousch mixture first and procede as I first outlined.
