polkat Posted July 31, 2008 Report Posted July 31, 2008 Can I use roofing or road tar dissolved in turps to tint Tru-oil? If so, what kind of mix? I've used it to tint other varnishes but don't know about tru-oil. Thanks!

Bill Yacey Posted July 31, 2008 Report Posted July 31, 2008 That works.Joe I've tried roofing tar, the semi-runny stuff in a can, and it works fine. I would like to try the thick, solid stuff that the roofers melt when re-roofing.

I actually dripped and stirred it right into my already-too-red varnish to take some of the flamboyance from the color, until it looked about right. As far as the brand, I don't know. My cousin had an old pail of it and the label was all tarred over. If it smells sort of like black licorice and dirty motor oil it's probably the same stuff. It had the consistency of thick liquid honey.
tarawa1943 Posted August 1, 2008 Report Posted August 1, 2008 I have been using Tru-Oil for quite some time and also wanted to use, tar, bitumin or asphalt for tinting. I have found (through another Maestronet member) that Trans-Tint, which comes in many shades does a much nicer transparent job and is totally soluble in Tru-Oil.

The only concern about something like Trans-Tint and similar products is the unknown long time fading / stability issue. Bitumin is tried and true.
polkat Posted August 2, 2008 Author Report Posted August 2, 2008 At the risk of sounding stupid, what is Trans-Tint, and where can it be found? And what is bitumin? Thanks!

Trans tint is a dye that can be mixed with water, alcohol or varnishes (such as tru-oil). It can be found a many woodworking supply places on the net. try www.veneersupplies.com bitumen- asphalt
Mike_Danielson Posted August 2, 2008 Report Posted August 2, 2008 Bitumin is the same as asphaltum. They are not reliable colorants in the oil painting world--go to Meyer's book for the details--some serious long term problems. There are modern replacements for them. Do not violate the rules learned by the oil painters (always learned the hard way). Mike D
