Bitumen paint for walls.
Everbuild do a D.P.M. which is bitumen with latex as I recall, costs a
bit more tho.

Does anyone else have an opinion on bitumen vs. "dpm paint"?

I haven't found anyone selling the Everbuild one but Wickes do a
rubber/bitumen paint specifically marketed as a dpm and the reviews on
its web site are good.

I read here that two coats of bitumen paint would work. Would I need
two coats of the dpm paint or can I save myself a coat if I buy the
special dpm paint?

TIA
