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?

If the gashes you describe are not large, say more than 1/4 inch deep or more than say 6inX6in in size, don't worry about them. go right over them. If you really feel that they need to be filled, use the floor leveler. it does contains silicates which is only harmful in a dry dust state, and then only if you live in the stuff for a long long time. Once it is wetted/mixed and on the floor , there is no danger if you don't go crazy sanding it. You can also use regular drywall compound or quick set if you have the patience to wait for it to dry before starting your floor.
