This is at the beginning of spray paint learning curve. My hands were shaking, arms stiff, but recording this anyways. Get to start somewhere.
The first step in to spray sanding sealer, 2 coats, 1/2 hour interval. The sealer is made of solid, hardener, and thinner. The D-1015 thinner is for humid weather. D-1010 will be used in dry weather. Before pouring out the solid, stir it well until texture is even, then pour into measurement cup. Shake hardener container to even it up a bit, add hardener to measurement cup, stir thoroughly to combine. The last is to add thinner. Stir all well together. Fill in spray gun container, Adjust fluid and air force, spray evenly.
When sealer dries, sand with 320 then 400 grid sand paper followed by scotch bright for a even surface.
The top coat here is acrylic, made out of solid, hardener, and thinner again. 2 coats, 2 hour interval between coats. This is after the first coat. No sanding between coats.
Instruction for the top coat. 20 oz of solid works just right.
Make sure no dust comes in spray booth between coats. Clean gun really well afterwards.
A couple hours after the second coat of acrylic, make sure finish is dry, untape the gluing edge, glue the soundboard in piano. Thanks to Ellie's help gluing the big board in. First time spray and glue the board on the same day. Gratitude to our boss and Ellie's support.
