There’s the rub….I'm not going to be drilling into the cinder block foundation of my chimney for that anytime soon. I’d have to use adhesive, or hang it from the ceiling, or build a standing frame for it/them.
You ever work with drylock concrete sealer “paint”?(I use that term in quotes tongue in cheek)
You have to prep the surface, liberally with muriatic acid, and a wire brush.( fun stuff)
Then it’s like painting with rubberized, lead infused plaster. Goes right on…like ice cold peanut butter.
Becomes part of any porous surface it clings to
It works great. Cleans up like a dream, once it’s cured.
Sucks to put on.
I needed 30 gallons to do the 3 walls, and chimney foundation here.
That was almost 25 years ago….I was almost 25 years younger then.

I’m still picking it out of what’s left of my hair.
