How do you paint over white paneling that has urine stains ?

Wash the walls down with white vinegar,allow to dry,use two costs of a stain and odor block primer,allowing to dry in-between,,and paint

First you need to clean the stains to remove the scent crystals or every animal that is in the area will want to pee there.

I have found Nature’s Miricle to be amazing!

Next, prep your paneling by washing with a deglosser like NoSand or TSP.

Prime with a stain blocking primer like Zinnser

or Kilz

Then Paint

😊

Best to clean the urine off first. A sealing primer like Zinsser would be good to use before you paint.

I would clean the paneling with Murphy's oil soap, follow the directions on the bottle. You can change the color, as long as it covers the stains. Whatever you decide, use high gloss, you can wash it and it's hard to penetrate it.

I would wash it all with TSP rough it up with sand paper and paint., Good luck

Wash the paneling first to eliminate the urine spots and odor. then apply a good primer . I love Kilz primer then paint the paneling as usual...

I have used Killz on cat urine stained paneling before and it was wonderful.

Clean the urine first to ensure odor removal and paint adhesion. If its pet urine, use a pet enzyme cleaner first .

As someone who is renovating a house that had pets (my parents home) I would remove the panelling and put up drywall. That odor is hard to get rid of. We had subfloor that we had professionally treated and sealed for cat and dog urine and the odor came back. We had to replace all the sub floor in the entire home. (We rescue cats by the way). I recommend painting the walls with a paint that has odor absorbtion capabilities to be on the safe side. And I would do that after I use Kilz on walls and ceilings. Good luck!
