This might be kind of a dumb question, but if I'm going to be using my garage for my welding area, will there be a problem with slag from stick welding ending up on, or sticking to, the concrete floor? How about any molten metal or sparks? How far does MIG or stick welding generally throw sparks? Plasma cutting?

I also work on my bikes in the garage, and would rather not have to clean up the entire garage every time I weld to prevent metal sparks and shavings from getting into my bike tires. I'm thinking about what I'd do with welding screens and/or curtains to partition off the space, but am I overthinking it? If the mess stays pretty localized, then I could just keep all the bikes on one side of the garage and keep all the metalworking to the other side, and run the shop-vac once in awhile.

Thanks for the input!
