One of the critical decision points regarding the installation of natural stone veneers for interior or exterior walls pertains to how well these coatings will resist water intrusion. Considerable effort has been expended to identify the best strategies for resisting the effects of water exposure to retain a dry and mold-free environment throughout the building.

The problem lies not in the Stone material itself but with creating a system that will keep moisture from penetrating behind the Natural Stone Veneer. An accumulation of moisture beneath the outer surface jeopardizes the integrity of the entire wall covering and eventually weakens the subsurface. Over time, mold will develop that will require replacing all coverings and replacing all affected wall materials.

Following specific instructions during installation can eliminate the possibility of water damage and prevent the need for expensive repairs.

Strategies for Installing a High-Quality Stone Veneer Wall to Prevent Water Intrusion

Experts at ProCoat in Denver have determined that carefully addressing three areas during the installation will provide a healthy and beautiful stone surface without the fear of intruding water damage. The three steps to focus on are:

• Sealing window, door, and siding edges to close gaps
• Bigger flashing is need to protect the thicker stone veneers
• Create more weeps for any intruding moisture to escape

Careful attention to elements can reduce the likelihood of ever having a trapped moisture problem.

Minding the Gaps

The vertical spaces between door and window frames are primary culprits for allowing moisture into the inner parts of the structure. Knowing that the natural stone thickness is greater than with stucco or other sidings, using larger flashing to accommodate the cladding will prevent moisture intrusion. Bigger and longer flashing is far more acceptable for natural stone veneer coverings than flashing which is too small or too short.

Provide More Escape Routes

A sufficient number of “weeps” are necessary to ensure that any water that does intrude is allowed to escape quickly. This last line of defense is needed in any case, so make sure that there are an abundance of weep holes to carry out the mission of keeping your subsurface as dry as possible.
