Not sure if this is for plastering or the building section.
I have built a shed single block thick and one side of it which backs onto the boundary hasn't been rendered so the blocks soak in water.
Apart from rendering which can't be done on this side because a fence hides half of the wall, whats the best sealnt to stop water penetration.
Something like Thompsons water seal or another brand, or could I use Everbuild blackjack (bitumen)
