I did some patch work on our bedroom walls prior to painting; then used Kilz interior acrylic (not oil based) to prime those spots. I didn’t read the fine print good enough….and I have now painted two coats of paint (with primer) on walls, and all the Kilz spots continue to show through. HELP!!! Will the spots ever cover??
It depends on what you are seeing. Are the spots smoother than the surrounding wall or is there a sheen difference? What is making the spots stand out?
When patching walls and ceilings you need to pay attention to the texture that is present. Even smooth walls have a texture left behind from rolling paint on the surface, roller cover stipple. If this is the case you can take a little drywall mud and mix it in with a little Kilz (acrylic only). This mixture can be rolled over the spots to give them some texture, roller stipple. This is best done with a mini-roller.
If the spots stand out from a sheen difference, shinier, then just give everything time to cure. This effect should diminish after a week or two.
