Tasha… using asphalt emulation AE- (Henry's 107 and other roof tar, basement waterproofing, road asphalt mixes) have been used extensively in many ways. an inventor/house builder in the 1930s used it to mix with ground cardboard and cement/clay ( sound familiar?) to create Rub-R-Slate…and you just add some to a DRAINED PC mix…use in dry weather, and as the clay-AE -water mix evaporates it seals up to make a strong water resistant, even water proof covering. it is NON toxic..this is asphalt, not asbestos, which people mix up… standard black roofing paper is paper coated with AE used in house wrap, it's a long term use material.
I have used it straight right over old punk wood siding that I could not replace yet, then painted over it, it still is lasting 8 years later, it seals off the pours ness of any material it is on, which is a good thing.
it looks like pudding or wetter in the can, is cheap,and dries a dark drown. if you mix it, like I do, with clay, paper, lime, sand, ratios as a plaster it dries lighter in color.
adobe makers use it too in sun dried adobe bricks..so do try it,
there is always some question about smell..read the pail,it is safer than some paints, it is not ' offgassing' anything nasty.it has a road tar type smell, like most things do which ,goes away when dry, like house paint does.
you don't need much, and don't try to use it in wet weather, it needs to evaporate the water out of the mix, and the fine fine clay in the mix gives a 'body' to it so it adheres to paper or cinder block very well.
