Frequently Asked Questions

What Are Cultured Stone Products?

Cultured Stone is the registered brand name for our extensive line of manufactured stone veneer products.

How Are Cultured Stone Products Made?

Cultured Stone products are cast in molds taken from carefully-selected natural stone, using a process that faithfully captures even the faintest detail. Each color and texture uses its own blend of Portland cement, lightweight natural aggregates and iron oxide pigments. Even on close examination, these manufactured stones look and feel just like the originals.

How Do Cultured Stone Products Compare in Cost With Natural Stone?

The installed cost of Cultured Stone products is usually much lower than the installed cost of natural stone. Cultured Stone products require no additional footings, foundations or wall ties, and installation time will be considerably less than when using natural stone.

How Are Cultured Stone Products Sold?

Flat pieces are sold by the square foot, corner pieces by the linear foot, hearth pieces and trim products are sold by the piece.

How Are Cultured Stone Products Packaged?

Cultured Stone products are available in various package types from big boxes for large jobs to handi-paks for smaller jobs. These packaging types vary by texture. Please contact your dealer or call 1-800-255-1727 for more information.

How Heavy Are Cultured Stone Products?

While building codes allow up to 15 lbs per square foot, the average uninstalled weight of Cultured Stone products is approximately 8-12 lbs. per square foot.

Will Cultured Stone Products Fade?

Just as natural stone, Cultured Stone products will experience normal weathering during the life of the installation, no different than any other cement based material. See actual printed warranty for details.

Does the Color Go All the Way Through?

Base color is blended throughout the entire product. Color overtones are applied and integrated into the product during the casting process.

Will the Same Stone Appear Repeatedly in a Typical Application?

Cultured Stone products are cast from thousands of individual molds essentially eliminating repetition. In addition, to further eliminate the possibility of repetition, no two stones are ever reproduced with the exact same coloring.

How Long Will Cultured Stone Products Last and Are They Warranted?

As Cultured Stone products are a lightweight concrete material, they typically last as long as any quality concrete or masonry material such as concrete block, brick etc. Cultured Stone products carry a 50 year limited warranty. See actual printed warranty for details.

Do They Meet Building Code Requirements?

Yes. Cultured Stone products comply with applicable building code requirements. Details of building code approvals, listings and releases are outlined in our Installation Instructions.

What Kind of Surface Is Necessary in Order to Use Cultured Stone® Products?

Cultured Stone products may be applied over most properly prepared, clean, untreated, structurally sound wall surfaces such as wood, wallboard, masonry or metal. See the Cultured Stone® Installation Instructions for details.

How Are Cultured Stone Products Adhered to Wall Surfaces?

Cultured Stone products are installed using Type N or S Portland cement mortar over a properly prepared substrate. Thinset should never be used with our products. See Cultured Stone Installation Instructions or call 1-800-255-1727 for complete details.

Yes. Details on application over various substrates are given in the Cultured Stone Installation Instructions available on our website.

Can Cultured Stone Products Be Used on Fireplace Facings or the Wall Behind a Free-Standing Stove?

Yes. Cultured Stone products have been tested by Underwriters Laboratories Inc. Test results prove a class A fire rating, zero flame spread and zero smoke development. Always refer to the fireplace or stove manufacturers’ installation instructions and local building codes.

Will Cultured Stone Products Stain if My Fireplace Smokes?

Possibly, just as natural stone or brick will stain. Sealing the Cultured Stone products around a fireplace with a silane based breathable masonry sealer will assist in the removal of smoke stains should they occur. Smoke stains can often be removed by following cleaning instructions given in the Cultured Stone Installation Instructions.

Can Cultured Stone Products Be Used on Walkways or Patios?

No. Cultured Stone products are not suitable for foot traffic.

Can Cultured Stone Products Be Used on Wall Areas Adjacent to Swimming Pools?

From a durability standpoint, Cultured Stone products will perform the same as any quality lightweight concrete material. However, it should be noted that, as with any concrete or natural material, continued exposure to chlorine and other chemicals may eventually affect coloration. When frequently exposed to water, we recommend protection with a silane based non-film forming breather-type masonry sealer.

Can Cultured Stone Products Be Cut?

Yes. Cultured Stone products are easily cut and trimmed using a hatchet or wide-mouth nippers or with a masonry blade used with a circular or masonry saw.
