<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>: Sanding sealers are used to protect and finish wood surfaces after they have been sanded down. They can also be used as an adhesive between two different materials such as wood and tile or laminate flooring. The main purpose of sanding sealers is to fill in any gaps or cracks in the surface so that it will be smooth and even.
