Cultured Stone® products can be installed on any structurally sound, code-approved wall surface. However, surface preparation will vary slightly according to the nature of your project. As always, be sure that your installation is done in accordance with local building codes.
On clean, untreated masonry, concrete and stucco, no lath is needed, and Cultured Stone® is applied directly to the surface. Applications on a rigid back wall will require a ‘breather type’, weather resistant barrier, such as code-approved building paper and 2.5lb expanded galvanized self-furring metal lath, or other code-approved lath, or minimum 18ga galvanized self-furring woven wire mesh.
Open stud and metal clad construction require 3.4lb 3/8” ribbed paper back expanded galvanized metal lath.
