Installation Guidelines

INSTALLATION GUIDELINES

Eldorado Stone endorses and supports the Masonry Veneer Manufacturers Association (MVMA) Installation Guidelines. The mission of the MVMA organization is “To advance the growth of the manufactured masonry veneer products industry through proactive technical, advocacy, and awareness efforts.” One of the most important projects completed by the MVMA Technical Committee was the development of a highly detailed and carefully researched installation guide. The latest version of that guide can be downloaded at www.eldoradostone.com/resources. These guidelines are intended to share over 45 years of knowledge, experience and understanding regarding the proper installation of manufactured stone veneer products. For any specific or unique installation questions or challenges, including: • Traditional masonry installation methods • Installation over cement board using polymer modified mortar • Installation over thick foam; fastener selection • Installation of large format profiles Please contact Eldorado Stone’s Technical Support Service directly at 800.925.1491.

Note: It is important to recognize that Eldorado Stone and Brick veneer products are an adhered veneer or façade which are attached directly to a cementitious substrate for purposes of providing ornamentation and a first layer of weatherization protection. Adhered Concrete Masonry Veneers are not intended as a structural product or a waterprooﬁng element. Most importantly, the real subject matter expert is your local building department and the local building code. Your local building code will supersede all other written or verbal installation guides provided by Eldorado Stone or the MVMA. Go to ncma.org/manufactured-stone-veneer for more information about the MVMA.
