Cultured Stone® Frequently Asked Questions
Q. What are Cultured Stone® products ?
A. Cultured Stone® is the registered brand name for our extensive line of manufactured stone veneer products.
Q. How are Cultured Stone® products made?
A. 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.
Q. How can I get cost information and who quotes installed prices for Cultured Stone® products?
A. Contact your local dealer for prices and/or names of installation contractors who can provide quotes on your project. Call 1-800-255-1727 or visit our Where to Buy Section or via the “Send us a message” button on the main stone products page of the website
Q. How do Cultured Stone® products compare in cost with natural stone?
A. 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.
Q. How are Cultured Stone® products sold?
A. Flat pieces are sold by the square foot, corner pieces by the linear foot, hearth pieces and trim products are sold by the piece.
Q. How are Cultured Stone® products packaged?

Q. 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.
Q. Does the color go all the way through?
A. Base color is blended throughout the entire product. Color overtones are applied and integrated into the product during the casting process.
Q. Will the same stone appear repeatedly in a typical application?
A. 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.
Q. How long will Cultured Stone® products last and are they warranted?
A. 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.
Q. Do they meet Building Code requirements?
A. Yes. Cultured Stone® products comply with applicable building code requirements. Details of building code approvals, listings and releases are outlined in our Installation Instructions.
Q. What kind of surface is necessary in order to use Cultured Stone® products?
A. 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.
Q. How are Cultured Stone® products adhered to wall surfaces?

Q. Will Cultured Stone® products stain if my fireplace smokes?
A. 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.
Q. Can Cultured Stone® products be used on walkways or patios?
A. No. Cultured Stone® products are not suitable for foot traffic.

A. 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.
Q. Should I color the mortar?
A. Cultured Stone® product applications are enhanced when mortar is tinted to complement or match the stone color using iron oxide mortar colors available from Cultured Stone® dealers.

A. 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.
