How do I get a very smooth uniform paint surface?

Reader Question: How do I get a very smooth uniform paint surface? I am painting on smooth composition board. Also should I treat the composition board surface before painting?

To make a very smooth paint surface on composition board, here are the steps you can follow to prepare the board:

  • Using a flat brush, apply a coat of gesso to the composition board.
  • After the gesso dries, lightly sand the composition board using a fine-grit sandpaper. This will remove any bumps or imperfections in the surface.
  • Blow off any loose particles, then apply another coat of gesso.
  • After the gesso dries, sand it again using fine-grit sandpaper to remove any imperfections.
  • Repeat this process of applying gesso and sanding until you achieve a smooth, uniform paint surface.

I've used this technique several times to prepare hardboard panels for painting, so it should work for you, too!

Happy painting!
