New Paver brick patio ...bricks have white marks.
All the bricks have these white marks...calcium deposits? Something like that? The contractor said it was from them all being together and that the sand will draw it out and it will go away after it rains a few times.
Is this right? It's such an amazing beautiful patio, but the white marks almost look like scratches and I'm being impatient. Is there something I can do to speed the process? I want it too look clean and nice.
