Another motivation
for removing paint is that the common use of inappropriate
paints in the past can
prevent masonry walls from breathing. This can lead to
"blowing" of the stone-work, allowing damp
and frost to cause damage.
The process involves
applying solvent onto the painted surface and then, after
a short wait, washing the
solvent and the paint away with the hot water pressure
washer The paint comes away in layers and the process
is repeated until the wall is clean.
The technique can be carried
out on any masonry surface. Below we see the results of
removing years'
of layers of paint from 50 metres of limestone pub signage.
