How to Spray Polycrylic

Polycrylic, a Minwax product, creates a clear shiny finish on finished or unfinished wood. Minwax advises against diluting Polycrylic; since diluting the product is a first step for applying it with an HVLP spray gun, the results may not be desirable. The good news is that Minwax offers Polycrylic in an aerosol can, so you can spray it on without compromising the finish. Look for aerosol Polycrilic at home and garden centers and paint retailers.

  1. Prepare the surface by removing the old finish and applying stain or paint, if applicable. Regardless of whether the surface is finished or unfinished, it must be clean and sanded smooth. Wipe off the dust with a slightly damp microfiber cloth.

  2. Spray the surface with an even layer of Polycrylic. Allow the surface to dry for two hours.

  3. Sand the first coat of Polycrylic with very fine grit sandpaper and wipe away any dust with a damp microfiber cloth.

  4. Apply a second coat of Polycrylic, and allow it to dry another two hours, followed by another sanding and a third coat.

  5. Allow the surface to dry for at least two hours before use.

Warning

  • Always use spray finishes in a well-ventilated area.
