SandBossing uses common sand and eco-friendly binders to create sharp "embossed" prints that last several weeks and can be removed with a bit of effort.
Natural Media Experts has been developing this new natural media technique for several years as an alternative to reverse graffiti for countries where water is scarce. The recipe can be altered so that it is more or less durable depending on what is needed.
One of the biggest benefits of this technique is that it does not require heavy equipment. All you really need are a template, some sand mix and your two feet or a bike.
SandBoss prints are ideal for urban communication messages that are not too large. When prints are too large, the sand mix begins to dry and doesn't release as nicely from the template. Templates do need to be cleaned between each print.
Removing the prints can be done with a putty knife and a wire brush. Color pigments can be added to the mix as can liquid dyes.
