Hi, We are masons that sometimes install stone veneer at the front of houses. The way we have been doing it is by stapling tar paper (the same paper as roofing) to the playwood or sheetrock for waterproofing. Then we nail a wire mesh and we put a coat of concrete for the stone to stick to. After that, we come back next day and we start installing the stone against the wall. My question is: What is better for waterproofing in this case? - Tar Paper. - Black Paint (the one used for foundations). - Other? Since we nail through it, I am undecided. And since we are no carpenters, we do not know what is best to keep the water out... Please, let me know. Thanks.
