Default bubbles in polycrylic finish

i'm using the water based polycrylic satin finish on my painted gnomes and there are bubbles all over it. they form when i brush it on and i don't know how to get rid of them. i thought they might pop out before it dried, but now there are bubble marks everywhere. am i doing something wrong?

1. How good are your brushes? Some cheap/stiff bristle brushes hold air and leave bubble streaks.
2. Are you scrubbing the finish into the wood? That will make it foam for sure.

Other that those well learned upscrews done by yours truely, I have no idea.

i'm using Minwax water based polycrylic. i was putting it on with a cheap foam brush. that's what i was taught to use when staining wood projects, i guess that doesn't transfer to carvings.

Make sure to stir the finish slowly to avoid bubbles. NEVER shake the can. If you must brush, use a bristle brush and brush very slowly and carefully so as not to raise bubbles. Spraying is a better way to apply it to avoid bubbles.

Staining or finishing a flat wood surface is different than finishing a wood carving and different techniques must be used.

The best way to get rid of bubbles is to pop them with a hair dryer or heat gun as soon as possible.

I thought them foam brushes were invented by Martha Stewart <Grin>. Never had much use for them.

thanks guys. I was doing everything you're not supposed to do! Shook the can, used a foam brush, brushed it on quickly... I like learning the hard way.
