<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 a type of coating that is applied to the surface of a floor after it has been polished with a floor sander. It helps to protect the floor from damage and wear caused by foot traffic. The sealant can also provide an extra layer of protection against stains and dirt. Sanding sealers are available in both liquid and spray forms.
