i have several walls susceptible to mould growth, black spots. having
eliminated the majority of the cause of the damp, i now want to strip
off the paint on all the internal walls, back to the plaster, then
repaint with an anti mould paint.

wickes do one for 9.99 per 2.5l, own make, home base do a branded one
in a red tin for 24.99 which seems a lot.

can anyone recommend me a product for the job? also does this anti-
mould paint have to be the only paint on the wall or can you paint
over it?
