Painting prepainted wainscoting panels

I purchased this wainscoting from lowes

Here's my issue. After painting two panels, I'm noticing that virtually anything hard that hits it causes paint to dent, which easily peels off. The paint is a primer and paint in one, but do I still need to primer the panels or is it the kind of paint that's the issue? It's labeled an "Acrylic paint" on the can but I've only heard of this for craft paints. I'm guessing maybe it's actually a latex based paint and I need an oil based paint to prevent this from happening?

 

I would have given it a light sanding to give the paint something to attach to, cleaned it off and used an enamel paint.
Should be no need to prime it.

 

I agree, a light sanding along with an enamel paint. Wall paint or cheap latex enamel won't preform well. Oil base, waterborne or a decent quality latex enamel should all do a decent job. Any sheen of enamel will work. My preference would be a waterborne enamel.

 

Well that's what I get for trusting the paint clerk. Can I sand this acrylic paint and put an enamel paint over it or are these panels ruined? Thanks guys.

 

A lot depends on how well your paint is adhered to the panel. As long as the paint is adhered well you can paint over it with enamel.

 

FWIW, one will generally find better products and advice in a paint store than a paint department.

 

The paint adherence is what I'm concerned about, I can gouge it with a fingernail then peel it off, I guess I'll either have to get the paint off or toss these two I painted.

 

How long has the paint had to cure? Latex paints don't fully cure for a week or so.

 

It's been a little over a week now.

The paint surface I painted over was very smooth and hard, considering all I did was clean it I suppose I shouldn't be surprised it peels off so easily.
