Luthiers, Builder question on finishes
Instruments- discuss specific features, luthiers, instrument problems & questions
My buddy Lowell Hodel and I have built 2 mahogany body/Sitka spruce top dulcimers and used a variation on Dwain Wilder’s recipe ( https://www.bearmeadow.com/build/materials/finishes/html/shellac.html and https://www.bearmeadow.com/build/materials/finishes/html/varnish.html ) which we’re very happy with.
2-3 light coats of 50-50 Zinsser sealcote (dewaxed shellac) and a specific denatured alcohol that has no water or unknown impurities in it (KleanStrip).
6-9 light coats of semigloss Target Coatings emTech EM2000wvx Waterborne Alkyd Varnish. With this finish the dilution of the shellac is mandatory - at full strength the shellac beneath causes the varnish above to check; at half strength, it is a perfect sealer and causes no checking at all.
Topped by TreWax paste wax - clear for the spruce top and mahogany colored for the body.
