Faux Finishing - Textured Old Mission wall style photos or color chips

I am trying to locate either photos or chips that would show the color and texture of an old mission wall like one that might be found in Calf. It would look like it was over 100 years old and aged with discoloration and dust, soot and severe aging. I can't seem to get a designer to visualize what it might look like.

Thanks

I think you mean Mission like Spanish Mission not (art imitates art) Craftsman Mission?

Like that?

Thanks for your quick reply. Yes I do mean Spanish Mission but I am thinking of interior walls which show deterioration, yellowing and age from candle smoke, soot and other stains from being "lived in" for a long time.
Thanks again.

Plaster then. You'll want to prep for this, such that parts crumble off when you whap them. I would smear largish areas with oil - as a "release agent". Let it set up and then attack it like a drunken mover. Then wash, paint, and repeat the bad plaster. This is going to be a thickly built up wall.

The key is in willfully working against manufacturer's instructions. We want the applications to fail. If they say don't let it dry too quickly, then hit it with a heat gun.

I know plaster can be made to crack... like eggshell cracks... but the artist I interrogated wouldn't share her secret. It did involve a dilute stain to darken cracks.

I find the most authentic antiquing comes of natural/thoughtless processes, not a deliberate & artful touch. For example, if I want to antique a piece of hardware, I might bury it in wet soil for a week, then carelessly polish. In the case of your walls, you might try dragging past them with an ungainly bundle of dirty (I mean garden soil dirty) tarpaulins. Scrub some dirt off halfheartedly and then seal. You can simulate ages of settled dust by - you guessed it - generating dust, then sealing it. And so forth. Let nature do the work.

Have fun. :)
