Once the enclosure is assembled it needs to be prepared for painting. All edges need to be flush with one another and all gaps need to be filled with wood filler.

First, sand any edges that stick up. A power sander makes this much easier but still takes lots of time so be patient. I used 60 grit sandpaper; for this part, the more coarse the better.

After all edges are flush with one another, fill in the gaps with wood filler. Use a putty knife to lay down the filler and let it dry. Do this for all the little holes that appear on the edges of the particle board too.

Sand the whole box again with a finer grit sandpaper. I used 220 grit for the second time around. If you find any more holes that need to be filled, repeat the last step.

Sand it again with even finer sandpaper such as 320 grit and finally 600 grit. The surface should feel completely smooth. Be sure to sand the corners a bit, rounding them to your liking.

The box is now ready to be painted.
