Just take your brush and run it lightly over the bubbles, going with the grain of the wood, to make them disappear. You may be able to do this even if the finish has hardened somewhat and is tacky. Once the finish has fully hardened, however, the only way to fix bubbles is to strip the finish and recoat the wood.

How do you keep wood from bubbling when staining?
One of the best ways I know to prevent bubbles is to wipe the finish on with a rag instead of using a brush. You will need to dilute the finish about 50% with mineral spirits or naptha, and as a result, you’ll have to apply more coats. But its well worth it for the smooth finish you’ll get in return.
What causes stain to blister?
A: Blisters form when the top layer of paint lifts from the underlying surface. There are many possible causes. The surface might have been dirty or the weather too hot or cold, or moisture could be moving through the wall and pushing the paint off.
How do you get rid of bumps on polyurethane?
“The only way to correct this issue is to strip the finish down to bare wood, wipe it thoroughly with denatured alcohol, and restain. Next, brush on a couple of coats of dewaxed shellac, such as Zinsser’s SealCoat.
How do you fix polyurethane mistakes?
Many can be corrected by sanding and recoating.
- Pop bubbles that appear when painting or spraying polyurethane with the tip of a paintbrush.
- Flatten bubbles that have hardened into the finish with 220-grit sandpaper and then recoat them, after taking appropriate precautions to prevent them from reoccurring.
Can you use a torch to get bubbles out of polyurethane?
Blow Torch Method Many woodworkers use a small, handheld propane torch to get rid of unsightly bubbles in water-based polyurethane layers. The flame is passed over the bubbles until they melt. When finished, the polyurethane should have a glassy finish that is completely free of bubbles.
How do you fix bubbles in paint on wood?

Will bubbles in paint go away?

Can you sand down water damaged wood?
Sand the furniture in the direction of the grain. Sand the water-damaged areas first. Remove wood dust with a clean paintbrush, and continue sanding the remainder of the furniture to even out the finish. Again remove wood dust with the paintbrush.
How do you get moisture out of wood?
Place a dehumidifier in the center of the room once all of the standing water is removed. Set it to the highest extraction setting possible. Turn it on and leave it running for at least 24 hours to pull moisture from the boards. Place fans blowing across the surface to further aid in drying the wood out.
Why is my clear coat bubbling?
If the clear coat is applied too fast, tiny pinholes will come to the surface. These pinhole size bubbles are the result of the paint needing to escape but the top skimming or clear coat was applied faster than the paint could escape or breathe. These tiny pinhole sized bubbles can be easily fixed.
