I have asphaltum liquid and have only used it twice ( both times experimenting with it).
I have mixed it with clear,and apply and have also just reduced it on its own ,air brushed it wet on wet with amazing results.
Basically i have been using it as an aging element on signs.
I was just wondering how others use it, or other uses you have found for it?

Works great for filling in the low spots in cast or engraved metal to bring out the design. Did that on a few belt buckles. Brush it on, let it dry, remove excess with a rag & acetone. Dries very hard.

Hi Robert. There was a very good and interesting article in SignCraft by Mike Jackson, involving the use of Asphaltum for glue chipping. I can't think of the exact back issue that it's in, but if you do a quick search of their index of past articles, I'm sure that you'll find it quite easily.That'll give you another use for it.
Hope this helps.

It's used alot for shading gold leaf scroll work.It makes flat designs look three dimensional by brushing a light glaze coat over the gold creating shadow effects. or you can use it over a multi-colored rendering to create shaodows that go over several adjacent colors. Shade-shifter vinyl mimics the transparency of an asphatum glaze.

I've tried using it to shade gold like Jeff mentioned. Loaded half the brush with asphaltum the other with One Shot clear, blending it on a palette. I found it got extremely sticky after the first pass or two. Is there a way to avoid this? Something to reduce it with maybe?

You reduce asphaltum with spirits or paint reducer. I use it as a coating on glass that will be glue-chipped.

Hi Terry. I'd try using a different clear. The 1-Shot Clear is a very fast dryer, and that's what's most contributing to the "stickiness". A spar varnish would be slower drying, and be more compatable with the asphaltum....especially if you're attempting to blend it on the pallette.

Terry...
You need to thin a small quantity of asphaltum with a quick drying varnish...just enough to be dark, but not so dark it gets streaky when brushed. Then brush on where you want to have shade, then let it dry. Then put on second coat, let dry, then a third coat. On each pass, the next coat can be a little in from the edge of the one under it. That makes the shading look gradual. Anyhow, that's how I do it over gold leaf............actually, it could be done with automotive clear I reckon.......
