Fixing a bad base application! (Flaking problem)

We recently made the mistake of using a chemical deglosser instead of sanding some older, fake-wood paneling before painting. At least I think that was the problem -- since we also used a paint type I wasn't familiar with (Matte Ceramic, WallHide).

Bottom line, the lightest plastic child's toy hitting the wall causes a problem. And by problem, I mean the paint flakes off to reveal the wall behind.

Obviously, we're going to have to repaint, but this is a HUGE room with a ton of angles, so removing the paint and sanding the walls properly isn't likely to happen.

My question: is there an impact-resistant type (or brand) of paint out there which will bond with ITSELF enough that scratching/flaking from mild contact will be less likely to occur? Or will anything decent that isn't "matte ceramic" do the trick?

Best guesses or other suggestions are welcome! Thanks!

 

How did you apply the liquid deglosser? It should be applied shortly before the primer and the rag must be turned or replaced as needed so you don't smear around any contaminants that might also be on the substrate.

What type of primer did you use? Paneling or wood finished with poly/varnish needs to be coated with a solvent based primer before it will accept paint. The primer will bond to the wood, latex paint usually doesn't

It would be best to vigorously sand the walls, reprime and then paint. You might try zinnser's peel stop primer - RustOleum.com

I'd suggest top coating the walls with a quality satin or eggshell latex enamel.

 

I think I applied according to the instructions, though I probably should have been more diligent about swapping out the rag. In fact I know I should have. The surface was visibly deglossing, so I guess I assumed it was going to be successful. I didn't use a solvent-based primer either. (This project...not my finest hour as a handyman.)

Since this room is large, problematic and serves as our kids' bed/play room (really our entire upper half-story), I'm afraid a mass sanding job is out. Thanks big-time for the Peel-Stop primer recommendation, tho! Sounds like a great idea at this point!

 

You have an adhesion problem between the paint and the walls - I'm dubious about anything fixing that without removing the paint first

 

Oy. I think I'd rather sell the house than tackle a project of that magnitude. :-/

 

Just to make sure I was clear, sanding off any loose or unbonded paint is best! Chemical removal would also be an option but not one I'd care for.

The peel stop primer isn't a miracle worker but it's about the only coating I know off that might help.
