david32knyte Posted July 18, 2014 Share Posted July 18, 2014 I need to find a way to dirty down interior and exterior walls that is only temporary.It needs to look like soot. I was thinking black powder paint but if it rains that will come off. Link to comment Share on other sites More sharing options...
top-cat Posted July 18, 2014 Share Posted July 18, 2014 Sadly there are not many "temporary" solutions for any such things which won't come off in the rain!! Link to comment Share on other sites More sharing options...
ddproduction Posted July 19, 2014 Share Posted July 19, 2014 Weather some gauze or scrim that can be hung to cover the walls? Link to comment Share on other sites More sharing options...
the kid Posted July 19, 2014 Share Posted July 19, 2014 Flints might have a good idea. They do that no damage wall paper. I can't imagine that black powderpaint is good really for any surface, you are bound to get smudges when it comes off. All depends on how much you like the space you are going to.

david32knyte Posted July 21, 2014 Author Share Posted July 21, 2014 Thanks to all who replied. I am familiar with 'Mask-it' and 'Peel' temp wallcovering products. Was hoping for a powder mix treatment. Prob doesn't exist or wouldn't work. Any further suggestions would be very welcome. Thanks David Link to comment Share on other sites More sharing options...
adam2 Posted July 27, 2014 Share Posted July 27, 2014 I doubt that you will find a product that is easy to remove but that will withstand rain. How does the product "know" the difference between the rain that you wish it to withstand, and the water from a wet cloth or mop, or a hose that you want to easily wash it off ? A possibility would be the old fashioned powdered paint pigments sold by Flints. These are intended to be dissolved in water with the addition of a fixative known as size. Try using ONLY the pigment dissolved in water without any fixative, this results in paint with very poor durability. It will still be somewhat vulnerable to rain though, and may need a determined attack with scrubbing brush or pressure washer for removal. I have used this to simulate smoke stains for filming purposes. Link to comment Share on other sites More sharing options...
