I applied a coat of Arm R Seal to some mahogany on Sunday of this week. The pieces have set in my unheated garage and the temperature outside has been between 65 and 35 F. I believe on Wednesday, I noticed a white splotch in an area of the finish. I sanded down the whole piece with 220 grit sandpaper that day (white powder is what came off while sanding) and applied a 2nd coat. Today, I noticed more white splotches, probably where I applied the varnish a little bit thicker. What’s going on? I thought 3 days to dry would be enough even in this colder weather. Do I need to heat my garage? Help, Please!
BTW, on Saturday, I stained the mahogany with GF water-based dye stain. Was a day not long enough for the dye to dry?
Edit 2: Maybe what I am seeing is called blushing? At 11pm tonight, weather underground says the humidity here is 75%. I also read I might be able to get rid of it with a hair dryer by evaporating the trapped moisture causing the blushing. Thoughts?
