How to get rid of weird round circles appearing under fresh paint?
+4
My husband and I recently refinished a buffet table; sanded it, cleaned it, added paint, and gave a distressed look to it. However, we are starting to notice these weird round stains appearing. We thought they were the knots in the wood at first, but there are not. What could they be and how do we get rid of them? We understand that we will most likely have to remove our paint job, we are okay with that, we just want them gone (or stop them from showing up)!! 2 shown in picture, but there is a lot more throughout buffet table. Please help!
It's looks like whatever was under is bleeding through. I would remove the paint and apply a primer first before painting to ensure your paint job comes out smoothly
Need to use shellac-base primer-sealer before painting to seal the knots and keep them from showing through. A good one is ZINSSER®
B-I-N® Shellac-Base Primer.
Yes, the primer will seal those and prevent bleed. I like using Kilz. It is stinky, but dries quickly and won't allow problems to resurface. It even works to prevent cat pee from coming up into the carpet if a damaged floor is sealed with it.
This could be from something residual that bled through or something referred to as knot stains. When re-painting, apply a stop-bleed product prior to painting the color.
They are tannins from the wood leeching through. Its very important to use primer, you will have to strip it and try it again
Its not the wood knots and we sanded A LOT before applying paint which has a primer mixed in it...any other suggestions? They were not there before we painted, only started appearing a few days after painting (not dirt either, we tried scrubbing).
try a coat of kilz stain blocking primer then recoat the blue.
