Efflorescence is such a common building defect around Sydney and Australia. Did anyone else see Gardening Australia last night? Above: Check out the efflorescence coming up out of the grout joints from the tile bed on these balconies just next to Costa Georgiadis as he reported from an apartment complex in Redfern, Sydney. There was a fair bit of efflorescence seeping from render as well during the story.
Using Efflock is the very best prevention for efflorescence. So simple and very economical.
