This is the ninth post in a series documenting my method of construction for an entire set of custom kitchen cabinets. This series is not intended to be a full how-to tutorial, but rather to show the sequence of steps using photos and commentary. You can find all the posts in the series here.

After the stain has dried outdoors for 24 hours I apply two coats of Pettit marine spar varnish.
This varnish goes on thick and dries to a very durable, high gloss finish. I am just using it here to build up the finish thickness in preparation for the satin topcoat. I brush on the finish using a 3” Jen foam brush. Jen is the only brand of foam brush I use – boxes of them are available on Amazon or other distributors.
The two coats can be applied about 8 hours apart. Below you can see that the grain is not completely filled. Were this a table or desktop I would continue to build the coats three at a time, sanding in between each set, until the grain is completely filled. Since this are the insides of cabinets, that is not necessary.
After the varnish has cured for a full 24 hours, I sand the panels with my random orbit sander at 320 grit to smooth the surface, creating a cloudy appearance in the process.
Thanks for reading. In the next post I will use the Festool LR32 system lay out and drill all holes for the hinge plates, shelf pins, drawer slides and other hardware.
