What transparent spray-on material darkens it's background?
Im looking for a way to evenly darken an area of a wall, while keeping the 'background' visible. The effect Im aiming at is that of a shadow cast on the wall, sharply distinguished from the lighter surroundings but still showing the texture and perhaps images underneath. I am specifically looking for a material that can be sprayed, for example with a air pump spray
but a spray can would perhaps even be better. I bought a transparent lacquer in a spray can, but it turned out to be too transparent. Another option could perhaps be to dilute black paint?
A few conderations:
- I prefer to spray it (fast and evenly)
- Background to 'paint' on will be brick and wood
- Preferably non drip (or not too much at least)
- I want to cover a small area several times and will use a stencil template.
How would you go about doing this? Do you know of ready made materials in spray cans that do the trick? If you know of a specific liquid, where could I buy it?
Many thanks in advance!
