We’re pretty sure you don’t fancy coming home to your newly refinished floors and then spending days on end cleaning up all the dust left behind. Because the dust made by the sanding machines is so fine, it gets on to and into everything. Absolutely everything. If not contained, you’ll be cleaning it out of your cupboards, closets, curtains and duct work for weeks to come.
Another concerning issue is the hazardous nature of the floor sanding dust. The first sanding pass removes the old coat of existing finish. Most, if not all, finishes are very toxic. If you have an older house, who knows what is in that coating applied decades ago. Without proper dust mitigation, you, your family and your pets will be breathing in those dangerous substances.
The final reason dust is an issue for your project is to do with the quality of your coatings. If your home is full of dust after the sanding process, some of it WILL end up in the finish. That’s ok for the first few coats, but you don’t want that happening on the final coat. Nothing is more annoying than paying thousands of dollars to restore your floors and then seeing and feeling lumps, bumps and debris on it.
