Can we talk about using a hairdryer to speed up polyurethane drying? I thought it was a terrible idea until I tried it on a small test piece.
I was finishing a maple dresser top last week and needed to get a second coat on before the end of the day. The can said 4-6 hours to recoat, and I was stuck. I remembered a guy at a supply house in Boise mentioned using a hairdryer on low heat from a foot away to gently push the solvents out. I always thought that would cause bubbles or cure issues. I cut a scrap piece of maple, put on a coat of oil-based poly, waited an hour, and then used my wife's old Conair on the cool setting, keeping it moving constantly about 12 inches away. Checked it after 30 minutes and it was dry to the touch, no dust stuck. I went for it on the dresser and it worked perfectly. Saved me a whole afternoon of waiting. Has anyone else tried this with water-based finishes, or is it strictly an oil-based trick?
