For centuries man has built structures of all shapes and sizes using Mother Nature’s gifts. Natural stone has been the universal building block. Many attempts have been made to replicate Mother Nature’s creation, but aesthetically fall short of the real thing. Here in Texas, we are one of the largest home building markets that incorporate natural stone into our designs. The diversity that natural stone provides allows us to capture many different looks whether it be a rustic traditional or modern/contemporary and everything in between.
In recent times, a new demand and use for stone has forced technology to revolutionize stone as we know it. Homeowners wanted to utilize stone in areas not structurally built for the traditional full thickness veneer stone, which led to the creation of the Natural Stone Thin Veneers. In accordance with building code, any stone that exceeds 15lbs p/sqft cannot be classified as a “true” natural thin veneer and structural modifications, such as lentils, brick ledges, etc. will have to be incorporated.
These thin veneers can be installed utilizing a few different methods. One method is to use metal lathe over an existing drywall or hardy-board surface. First step would be to install a moisture barrier and then the metal lathe over the moisture barrier. Important, but common oversight is to ensure that when installing the lathe the ridges are facing upwards to aide the scratch coat adhering to the lathe. Secondly, apply a coat over the metal to give the “thin set” or mortar a surface to adhere to. Third step, apply the stone using a mortar/thin set to the scratch coat. Most “natural thin veneer” companies will give specifications on the mortar mixture for the stone installation.
For installation of stone on existing surfaces such as brick or concrete masonry unit (CMU), ensure the surface is clear of paint, debris, and soil. A mason can apply the mortar/thin set directly on these surfaces without utilizing the metal lathe. It is important that all paint be removed from the surface of an existing wall to ensure the mortar/thin set adheres to the wall. Cement board can be used as well for as an installation surface.
A few tips to remember when installing thin veneer stone. A mason should start with your corner pieces and work your way to the other corner. Layout your stone in an arrangement desired by the client rather than “grabbing the first available” out of a crate.
Technology has allowed man to appreciate Mother Nature’s beauty within the home by creating the natural thin veneer stone. On your next project, new construction or remodel, consider natural thin veneer stone to increase the value and create the warmth of Mother Nature.
