Can I spray varathane sanding sealer?
Just so, can you spray sanding sealer?
This lacquer sanding sealer is formulated to work best as a first coat, it is easy to sand, and speeds up finishing because it dries fast. One coat will seal hard wood, soft wood, plywood, particleboard and mdf. It is non-toxic when dry. Available in convenient 12-ounce aerosol spray with an adjustable spray valve.
Regarding this, do I need to use sanding sealer before polyurethane?
Polyurethane bonds especially poorly to sanding sealers, so most manufacturers of polyurethane discourage their use. Furthermore, polyurethane sands easily, so there isn't any need for a sanding sealer.
A sanding sealer can be used on bare, unstained floors, doors, furniture and cabinets prior to applying either an oil-based or a water-based clear finish. It is designed as a base coat that will dry quickly, seal the pores, and sand easily with fine sandpaper to create an ultra-smooth foundation.
