I didn t shake the can and the brush didn t leave any bubbles behind.
How to keep bubbles from forming on polyerethane floor.
Suggestions re bubbles in polyurethane.
Painters and furniture finishers hardly ever apply polyurethane with a roller because of its propensity for forming bubbles.
Try thinning the first coat 5 to 25 percent to allow the poly to seal the pores 3.
After i stripped sanded and stained my solid oak kitchen table i brushed three coats of polyurethane on the underside.
Use a good china bristle brush and flow the poly on the substrate.
It came out great.
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.
However to reduce the chance for bubbles to form you should use a natural bristle one.
You may be over brushing.
Pour more material as needed.
Go with thin coats.
This type will not create foam or bubbles when used to apply the finish.
It isn t difficult to avoid making them in the first place it just.
Do not over brush.
Keep it on the floor at all times even when you turn and hold it at an angle so material trails off one end.
But large bubbles formed in the second coat about 10 minutes after i applied it.
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.
Dragging the finish in a continuous motion across the entire floor greatly reduces the likelihood of bubbles forming.
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.
