Previous owner painted a 3 ft. by 4 ft. rectangle with magnet paint on kitchen wall. He/she used very heavy strokes. Paint is thick, has ugly, thick lines and bubbles all over.
I've been unsuccessfully trying to remove this thing so I can repaint the kitchen. First, I tried scraping with a paint scraper... it didn't do anything. Then tried sanding with coarse sandpaper... applied heavy pressure for about one hour until my arms got tired and nothing. All it did was smooth out the thick brush lines and bubbles a bit.
If I could sand it down to a smooth look, I could apply primer then paint, but even after one hour of vigorous sanding, I cannot remove or smooth the magnet paint enough.
