- 1 Lb. tree sap/pitch -- I used mostly Douglas Fir
Boil gently on a hot plate to remove natural turpentine, otherwise it takes too long to dry
strain through screen into jar while still warm
cover with denatured alcohol
wait 24 hrs for everything to dissolve, then filter through cheesecloth.
Works similar to shellack, but my mix ended up a little thicker -- drys fast, covers well and has a glossy clear finish. I added 10% mineral spirits to one jar to slow down the drying and that worked ok. Finishes up real well with some furniture wax. My test coatings look fine after 7 months, no deterioration.
