I have some gashes in my sub-floor that I'd like to fill/level before placing laminate flooring down. Upon checking at my local home depot, I found some floor leveling compound but quite frankly, I'm scared to use it. There are very large warnings on it confirming that the contents of it are a known carcinogen and shouldn't be inhaled, touched, etc.
Now obviously I'm going to be wearing all required safety equipment but I'd much rather use something a little less toxic. Is there anything else I can use to level-out small imperfections in my sub-floor?
