I have a desk top that is 5' x 30" and I'm finishing with water based polyurethane. I used a brush on the cabinets and I have tiny bubbles in places that are ok on the cabinets but would not be on the top. How can I avoid the bubbles, I'm being as careful as possible when brushing but still end up with some bubbles. Even sanding still leave little bumps.
I don't have a spray gun so I need to go with a brush (which are top notch). What can I do to minimize or better still eliminate the bubbles.
Do I need a material other than polyurethane?
Thanks,
Jim
