<human>: I've heard that I should be using a sanding sealer on my floors, but I'm not sure what it is. Can you help?
<bot>: A sanding sealer is used to protect your floors from scratches and abrasions during the sanding process. It's typically applied after the sandpaper has been used to create a smooth finish. Sanding sealers are usually made of an oil-based or water-based material and can help prevent dust and debris from settling into the pores of the flooring surface.
