Technically, this is really Part 4 of our Wall-Hanging Tool Chest build, but because I focused so strongly on waterborne finishes and HVLP (High Volume Low Pressure spraying), it received its own stand-alone title.

When I made this project in the Guild, I asked our members what type of finish they would like to see me use. The votes came in and the majority of folks wanted to see a waterborne finish applied via HVLP. So my finish of choice was General Finishes High Performance. I used the Earlex HV6900 to do the spraying and I was thrilled with the results. Even after a couple of year of use in the shop, the finish is still holding up very nicely!

This video serves as a nice introduction to the chemistry behind waterborne finishes, HVLP techniques and spray gun maintenance.

Thanks for the demo. I enjoyed it. Finishing is the most important part of a project and the part I’m least skilled.

Very nice video as always Mark, In lieu of boiled linseed oil would recommend Seal A Cell from General finishes. It dries overnight and sands great. In the future, would like to see a project and your thoughts on a portable spray booth. Living here in Chandler AZ, it is very hard to spray outside in hot weather, Usually the first pass is dry after the third pass. Lets face it, this 100+ heat is very hard on spraying especially outside.
As always keep them coming Mark and the best of luck to you and yours.

I use dewaxed shellac (zinsser sealcoat) to give the wood a warmer tone before spraying waterbourne finishes rather than BLO. It dries in 45 minutes or less. For my waterbourne I like crystalac 2001. Dries in less than an hour and levels out perfectly. It’s a bit more durable then the GF.
I can get my entire project finished in one day.

Marc thanks for the tip on pre-raising the grain! you don’t waste finish that way for your first seal coat. We use a lot of Waterbourne on our projects. thanks.
