Now that the circles are sanded and smooth we are ready to apply the 1st coat of gloss varnish. Before we do we must get the surface free from dust and oils (like the ones that can come from our filthy hands).
For this I’ll 1st give the circles a spray with compressed air to remove any obvious dust.
Then a wipe-down with mineral spirits on a lint free rag to remove any residual dirt / oil.
Here’s the varnish we are going to use for the 1st 3 coats. Minwax brush-on oil based Polyurethane in gloss. The brush is a Purdy natural bristle brush specific for oil finishes.
I’ll start by finishing the bottom, flipping the circle over onto the bed of nails, then coating the sides and top. The idea here is after the top is done the item won’t have to be handled again.
The coat should go on light with the brush always moving in one direction with the grain…
Here’s a video of the top of the top circle (the most important surface) being varnished.
Here’s the top circle all shiny with wet varnish. Look at that awesome grain!
Clean up on the brush is done with mineral spirits in an old coffee can.
