Hi,
I'd like to waterproof my chimney with a vapor permeable waterproofing solution. I understand that chimney sweeps and repair people will do this for around $200, but I'd like to do it myself if possible. If it just involves brushing or spraying it onto the exterior brick, why not? But I'm having trouble finding the waterproofing chemical. Would anyone have information on where to get this?
Thanks.
