After i stripped sanded and stained my solid oak kitchen table i brushed three coats of polyurethane on the underside.
How to keep bubbles from forming on polyerethane floor.
You may be over brushing.
I didn t shake the can and the brush didn t leave any bubbles behind.
The first coat on the top looked good too.
Suggestions re bubbles in polyurethane.
It isn t difficult to avoid making them in the first place it just.
Go with thin coats.
It came out great.
However to reduce the chance for bubbles to form you should use a natural bristle one.
The foam will obviously cause bubbles to form and create a messy uneven result.
Even though it is an extra step in the process it will make the application of the polyurethane much easier quicker and likely bubble free.
Apply the minwax polyurethane finish with even strokes to avoid creating foam.
This type will not create foam or bubbles when used to apply the finish.
Try thinning the first coat 5 to 25 percent to allow the poly to seal the pores 3.
Use a good china bristle brush and flow the poly on the substrate.
Keep it on the floor at all times even when you turn and hold it at an angle so material trails off one end.
Painters and furniture finishers hardly ever apply polyurethane with a roller because of its propensity for forming bubbles.
It lengthens the process but once the wood is sealed you ll be applying the poly onto a smoother surface reducing the surface aberrations and reducing the likelihood of creating bubble pockets as you go.
Dragging the finish in a continuous motion across the entire floor greatly reduces the likelihood of bubbles forming.
They can form even when you use a high quality paintbrush however and if you don t catch them while they re fresh they become part of the finish.
