Use of manufactured stone on overhead horizontal surfaces.
Horizontal overhead applications are not supported by current evaluation reports or building codes. Please verify your installation with your building official and consult with an engineer for specific design issues on your project. There are grout and mortar manufacturers that will support their product’s use in these installations. Eldorado’s 50 year warranty would still cover our veneer products for manufacturing defects.

What is the installed weight?
The installed weight will vary depending on mortar used, grout method, and profile chosen. The stone will range 10-12 lb/ft2. In a standard application, there is also a 1⁄2” scratch coat, 1⁄2” mortar setting bed, and 2.5 lb/yd2 expanded metal lath to account for coat. If a specific weight is needed for a project, we recommend having an engineer evaluate the system.

How do you clean the stone?
To clean dirt or other particles from the stone, first try a simple soft bristle brush. If necessary, use a granulated mild type detergent mixed with water or a solution of no more than 1 part white vinegar to 5 parts water. Rinse well with clean water to remove any cleaning solution that might remain on the stone. Never use power washers, bleach, paint remover, or any other type of concrete cleaner.

How do you clean efflorescence?
When efflorescence occurs, as it does with many masonry products, it is the usually the result of moisture migration through the masonry substrate. Once the moisture is on the masonry surface, it evaporates, depositing dissolved salts in the form of efflorescence. Efflorescence will disappear naturally over time as long as the source of the moisture is controlled or eliminated.

If you wish to clean off efflorescence: Efflorescence may be removed with a solution of 1 part white vinegar to 5 parts water. Scrub using a soft bristle brush and vinegar/water solution. Rinse well with clean water.
