The Russians introduced ourselves to the ‘’bitume de judée’’. The first time I saw it was on the French forum. Alex talked about his receipe containing the following ingredients.
Beeswax: Slows drying time, soften the color and more transparent. Mixing it with the
bitumen allows beewax molecules to bind and make the asphalt more neutral
paraffin: help beewax or could be white wax candle
asphalt: Was used by the egyptians for embalming Oil soluble
pine resin: Gives plastic properties and can form a varnish if mixed with alchool
natural soap: probably for the oils in the soap
turpentine: Fluidity and solubility of the mix
siccative: shorter drying time, max 10% of total mix.
An easier version can effectively be done by mixing tung oil and bitumen. Depending of the bitumen solubility, an agent can be added to help to incorporate with tung oil. As long as bitumen is not applied in a too thick coat, there will be no problem to dry.
On the picture, concentrating on the first 3 tops ones, bare wood, tung oil, bitumen. Another way to apply it is with beewax + turpentine odorless to give it some flexibility and ease in application and add bitumen and then some polishing is needed (but this method is better suited for wood cabinet). Wax is easy to apply on large surface. but when too many corners, it is a less interesting option.
