I could use a little advice if anyone has experience with this. I've been doing murals for about 2 years, but the few that I've done (though very large) have been on standard interior walls. My latest job is on smooth interior concrete wall, and I am trying to find some information on how to prep and install the mural.
The client wants to keep the wall as is - with imperfections. The design is a map grid over top of the concrete with the concrete showing through. They want the paint to be translucent/thin in places, like the wall was painted a long time ago. Obviously no primer and the paint should soak in, no brush strokes. The concrete wall is very smooth. I'm concerned the paint will peel off and I'm also concerned if I do a wash of muriatic acid that it could damage the new flooring. I've tried to test on other samples, but all concrete I've found is rough and more akin to the kind you would find on the floor or on the sidewalk. So I havent been able to test yet on something with similar characteristics.
Does anyone have any experience with these materials? Any advice? Thank you!
If you can't do it naturally with paint, why not do it digitally as a vinyl application? You could make it as life like as possible and people won't know it. Plus if the client doesn't want it in future they can just peel it off, and the wall will remain the same condition.
Hi Dan! Thanks for the reply! I tried to go that direction, mostly because it was way easier. But they didn't bite. They want the grid to fade into the concrete at the edges almost like a wash. I'm just wondering how porous smooth concrete like this is, but I can't find anything similar. I was even trying to scout out parking garages, but security guards have gotten in the way.
I think a lot depends on your design and the surface really as there are many ways to skin a cat.
When we do them we tend to use spray paints (Montana Water Based) and stencils as you can build some really nice, soft effects and use a splatter cap and stuff.
If you have a painted, colour base you can also use that to go over it and knock it back but I guess not if it's bare concrete.
It sounds like the style of painting that you're wanting is "ghost sign" which is that faded out, old look so if you do a search for that then you'll probably have more luck finding some info but here are a couple of links to what I turned up.
