I am applying multiple coats of polyacrylic to a maple bowl, not because I want to, but because I have to keep sanding out little bubbles that form when I brush it on. I am using a reasonably good brush, and, as the label suggests, trying not to over brush it. i am pretty sure this is a technique problem, but I dont know what I am doing incorrectly. Any help?

Did you stir it vigorously or gently? Stirring vigorously or shaking the can will cause bubbles. If that’s not the issue try a foam brush.

Thanks. I don’t shake it, but I may be stirring it a little aggressively. I’ll back off a little on the next coat and see what happens. My experience with foam is that it makes the problem worse. It may, however,, all go back to stirring.

Why not wipe on the poly?

Take an old clean T-shirt and wipe on the poly

as Bill suggested and that’ll solve the problem.

Thin coats seem to work better than trying too
thick a coat.

I struggle with the Polyacrylic as I have tried it a number of times. I do much better with straight poly.

Have your say...
