We have just completed about 70 metres of graffiti on a store in Hayes - Middlesex.
Not just the odd tag - 3 x 4 metre tags - solid, with no wall showing underneath.
The wall was coated with anti graffiti coating and even that did not save the mortar from soaking up the paint.
Spoke to Roger Oakley, popped over to Tensid and got a couple of products - reading the data sheets - quite lethal products at that!! and still there is a very slight amount of ghosting that will not come off.
When the mortar mix is starting to come out around the brickwork, I have concluded that you can do no more!!!
99.9% removal is good enough for anyone!!!!
