Old angel stone is falling off lower section of the side of my house. Upper portion siding. Also stipulation to waterproof the wall.
Answers: I'm not sure about how to repair the stone but I can make a contribution you some good advice for waterproofing the wall. You should use a thorough water-repellant (water-based solutions are easier to use than solvent-based ones). You usually apply these products with a wet-on-wet application; you apply two coats, with the second coat self applied immediately after the first. Many people dream up you need to let the first coat dry until that time you apply the second coat; however, the second coat will then be repelled since water is the holder!
It's important to use a penetrating product as dead set against a product which "seals" the surface for two reasons: 1) freeze-thaw protection. When the substrate freezes, it will expand. If a product is sitting on the surface, it will cause the product to crack and outer layer. You want something that will be a part of the stone. 2) Vapor permeance. You want trapped water vapor to know how to escape so it will not break down the stone from the inside. Something that seals the surface will not allow water vapor to escape.
