A friend of mine’s mom had sent me pics of her patio that is about 5 years old. On the front of it, the bricks have a white hazy substance on them. Inside of the structure is filled with rock and cement i was told. Do you think the pics show effloresance, or is something from inside seeping through the joints? She said it was fine for 2 years and then this showed up. I plan on going out there soon. I wanted to order some efflo remover first. Thanks for any thoughts and ill drop new info as I get it.
