How do I stop the wood dust from entering the vents while I'm sanding the hardwood floor? I am thinking that stuffing with newspapers will do the trick, but this may have two flaws:
- It will not completely seal the vents. Some dust will make its way. (Does it matter?)
- The newspapers may be a fire hazard during the brief time the sander will be over the vents. (Can paper ignite from friction this easily?)
How does a professional solve this problem? The rectangular holes seem to be of standard dimensions. Is there a special device that will fit just right?
