Hello
Getting ready to put some laminate on MDF for a router table top build.
Decided to read the contact cement can and at the very top in bold it shows not to use next to gas furnace or water heater or to turn off gas valves / extinguish flames.

Wouldn't you know it, my shop just so happens to be my garage, which houses both my gas furnace and gas water heater.

So question is, is there really concern for combustion if I do my 30"x24" router table?

I don't really have another area to do this besides in the garage. The wife sure won't appreciate if I turn off the heat or water for a few hours either.

Don't want to blow up my garage, but at the same time I know these warning labels can be a tad over cautious.

What are your thoughts?

Thanks
Michael
