The variables of scratch coats, bond coats, and the exact surface preparation of exterior wall surfaces to accept manufactured stone veneer is highly dependent upon the construction style and materials of the wall. But no matter what the wall construction may be, there are a few general principles for installing manufactured stone veneer in Denver which you should observe so as to not let our harsh environment wreak havoc on your installation.

• The use of a silane based, penetrating and breathable type sealant is MANDATORY in areas of cascading water from leaking gutters, downspouts, balcony scuppers or drains, and any areas of high snow accumulation. Running water will attack the veneer, water marking it, spalling it, or worse, causing separation/disintegration of the mortar layer. Sealants should also be employed where smoke may discolor the product.

• Wall caps and post caps of adequate size must be employed to cover the majority of the manufactured stone veneer product. Water follows the path of least resistance. You don’t want that path to be between the installation and the wall anchoring it. Running caps where needed on the installation will keep rain and melt water from getting behind the stone and freezing. Water expands to as much as twice its volume as ice when it freezes. The freeze/thaw cycles Colorado, Utah, Wyoming and the like can pop improperly installed veneer from the mortar backing in an alarmingly short time.

• Instruct your client to not subject any manufactured stone veneer product to prolonged  contact with de-icing materials, salts, and other harsh chemicals. Exposure to even mild solvents such as these may discolor the cultured stone veneer, which is a cement-based product after all, or result in surface damage, and likely void the manufacturer’s warranty.
