Looking for the best way to apply polyurethane?
I have found the best way is to use a sponge brush, if you are using an oil based poly.:thumbsup:
I don't ever use a water based poly.:no:
Procedure: Apply 1st coat and try not to get it too thick, 'cause it will run. Wait 24 hours (more if the humidity is high). Sand with #0000 or #000 steel wool. Blow off.
Apply 2nd coat, this will go on easier, so watch for runs. Let it dry for 24 hours.
If you want a 3rd coat remember to sand with the steel wool lightly.
As a matter of fact I just put my second coat on 10 cedar boxes today. They sure look good now.:yes:
