View Full Version : Sand between polyurethane coats

01-20-01, 12:22 AM
I'm in the process of refinishing an old bird's eye maple dining room table and have gotten to the point where I've applied the first coat of polyurethane. Do I sand again before applying another coat? If so, what grit sand paper do I use and exactly what else do I do, if anything?

Thanks,

Trish

Trish:

You need to sand everytime before applying another coat of polyurethane. I would suggest 240 grit wet/dry, lubricated with water for this sanding. After the next coat, if you intend to apply a a third, sand with 400 grit wet/dry.

After sanding, wipe the surface down thoroughly to remove all the debris, then allow the piece time to finish drying from the water you used in sanding.
