Apply Multiple Coats of Matte Polyurethane

What happens here

Wearing a respirator and ensuring good ventilation (a temporary spray booth can be helpful), begin spraying the first coat of matte polyurethane onto the tabletop. Hold the HVLP sprayer at a consistent distance and move it smoothly across the surface, overlapping each pass slightly to ensure even coverage. Apply thin coats to avoid drips and runs. Allow the first coat to dry completely according to the manufacturer's instructions (often 2-4 hours). Lightly scuff sand the dried first coat with 220-grit or finer sandpaper to promote adhesion for subsequent coats and smooth any dust nibs. Wipe away all sanding dust. Repeat the spraying, drying, and light sanding process for a minimum of 3-4 coats, or more, depending on desired durability. The final coat typically does not require sanding. Allow the table to cure fully for several days before heavy use.

Goal: Spray several thin, even coats of the matte polyurethane over the stained tabletop, allowing proper drying and light sanding between coats for a durable finish.
