Air Bubbles In Wood Floor Finish

So our guy came to rebuff and put a 3rd coat of poly on.

Air bubbles in wood floor finish.

Bathtubs champagne ocean foam to name a few. We are having our pine and oak floors refinished professionally. Repairing bubbles within the finish of a hardwood floor requires removal of the old finish with floor screening pads and applying a new polyurethane finish. Generally as each application of finish is applied it tends to dry faster.

Step 1 remove everything within the room where you will be working on the floors. One place you should never find bubbles is in your hardwood floors. This happens to floor finishers who drag the finish applicator aggressively and then must stay off the floor until the finish dries. Right away we see the same air.

If you missed the bubbles while the varnish was fresh you may find the finish mottled with tiny craters or hardened bubbles. In my opinion the air bubbles that have appeared after the last coat of finish i call them fish eye bubbles are not necessary and not likely the fault of the person applying the 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. They are more common with a water based polyurethane product than a solvent based one because the water based product tends to foam and dry more quickly.

Bubbles belong in plenty of places. That causes the finish to become pockmarked with little craters called fish eyes that are easily mistaken for bubbles. The dust from the floor buffer can land and attach onto surfaces such as fabric furniture. Air flow will aid the finish to cure.

Next brush on a couple of coats of dewaxed shellac such as zinsser s sealcoat. To keep your floors looking their best follow these diy tips from altrufir.
