How to keep bubbles from forming on polyerethane floor.

Apply the minwax polyurethane finish with even strokes to avoid creating foam. Use a good china bristle brush and flow the poly on the substrate.

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. Suggestions re bubbles in polyurethane. The foam will obviously cause bubbles to form and create a messy uneven result.

It came out great. Pour more material as needed. It isn t difficult to avoid making them in the first place it just. But large bubbles formed in the second coat about 10 minutes after i applied it.

Try thinning the first coat 5 to 25 percent to allow the poly to seal the pores 3. However to reduce the chance for bubbles to form you should use a natural bristle one. This type will not create foam or bubbles when used to apply the finish. 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.
