Hi Folks
I've got an old west-facing large red-brick wall that no-one sees. I want to paint it bright white to reflect heat in Summer. What is the cheapest to use on this? I slapped some ultra cheap ceiling white (PVA I think) on an old red tile sloping lean-too just as a temporary sun shield thinking it would wash off in the first Winter rains. It is still the same six years later :)
