Guys we could use your help. We have an old squash court in Pgh. PA and looking to rehab the front wall, which is brick exterior, then clay/terracotta blocks (don’t ask, we don’t know why they did this in the 1930s) then scratch coat/metal lath, then finish coat. We tried weld/bond and cementious finish coat last year but it failed. Questions are whether it cured enough before painting, etc. Now looking at Armourcoat maybe. A gypsum product perhaps? Does anyone know why it is so expensive and tough to source? (10x regular plaster). Is it worth it would you say for this application? If anyone knows a great plaster with whom we could consult on a fee basis in Pgh. that would be nice. Best regards

thanks!
Most failure of cement coats to existing brick, cement or stucco is that it just doesn't bond.
Most jobs just require you to just soak the wall before the cement material is trowel on. A wall in the hot summer sun doesn't help the situation either. I see more failures on south and west facing walls.
