I have a wall facing a public right of way that needs protecting from the graffiti which appears very occasionally. Here is an old piccy from Google Streetview, though the wall is currently painted with white masonry paint.
I need something that will let be:
1 - Go over masonry paint after anything loose has been removed via wire brush.
2 - Is coloured to cover a bit of graffiti that has recently appeared. I think I am looking for white, brick red, or brown.
3 - Allows future graffiti to be washed off with a bucket and cloth or power washer. I may therefore need a 2 part system.
4 - Does not come off on people's clothes.
The area I have to cover is about 50sqm.
Any thoughts will be most welcome.
