Primer over Knotty Pine - Help

I posted this to the Paint forum as well...

Hi,

I'm trying to paint over our knotty pine paneling in the basement. The guy at the Mautz paint store told me if the paneling is shiny, I need to clean it with TSP (substitute) first, which I did. Didn't seem to do anything. I bought some Blox-It primer. I did a test to see if I needed to sand first (dh told me not to sand). The primer seemed the same in the sanded vs. non-sanded areas. So I primed the whole room without sanding. I let it sit for a few days.

Needless to say, a light scratch with a fingernail takes the primer right off. It doesn't take much to peel it off.

What do I do??? Help!!!! I feel so dumb about this.

Any advice will be greatly appreciated.

TSP (and substitutes) need a rinse after use.

Depending on what the finish was TSP substitute may not be strong enough to de-gloss sufficiently.

Sanding always works on glossy finishes but is a lot of work.

If the primer comes off easily any additional finish will not have a good base.

You may be able to scrub the existing primer off and start over.
