So I have had to move from my basement to the garage to prepare/finish my stair treads for installation. For years i have been finishing in the basement but the smell of the polly is too much and the boss kicked me out, lol, she was concerned about the vapors being ignited by the furnace. I moved into the garage but during the winter months it can get pretty cold in MD and makes finishing impossible. I checked the MSDS sheets of the minwax polly and they listed the polly as a flammability rating of 2. Now that i am concerned, i call the manufacturer and ask how i could safely heat my garage (while finishing) and he said that any method should work. I know many of us work in our garages, how do you guys heat your garages and should i be concerned with open flame while finishing?? Thanks in advance!!
