What is cultured Material (Marble, Onyx, Granatex)?
In layman's terms, cultured product is a mixture of resin and crushed limestone. A more technical description is as follows a cultured product belongs to the family of cast polymers. Cast polymers are a mixture of an unsaturated polyester resin, highly filled with inorganic particulates and pigments. Fillers used are engineered calcium carbonates (for cultured marble), aluminum tri-hydrate (for cultured onyx) and aluminum tri-hydrate with a suspension of specialty formulated color chips (for cultured granite) .
 
All three cast polymer products offer a polish finish that maintains similar features and benefits. The initial ingredients used to create these cast polymer products are what gives them their distinct appearance. The cultured Material is easy to install and maintain.
 
What is the difference between all three materials?
Cultured Marble starts with a blend of crushed limestone and is combined with high-strength polyester resins, simulating a natural marble finish.

Cultured Onyx has an aesthetically pleasing translucent finish which adds depth in the surface.
Cultured Granite is a similar blend but, freckling simulates pigmentation of natural granite.
 
What are the advantages of cultured products?
Cultured marble products are generally coated in the mold with a clear or colored gel coat. This outer layer provides the ultimate strength to the bonded martrix. It also makes the final product water proof, durable and resistant to chipping. Depending on the finishing process used, the gel coat also provides the shiny surface that adds luster to the final product.

Because the final objects are cast in mold, the installed product has minimal seams and when installed properly, using mildew resistant 100% silicone, it becomes virtually leak proof. Tubs are cast with the deck attached to the tub bowl in one solid piece. In residential construction, vanity tops typically have the bowl cast as an integral part of the vanity deck, avoiding potentially unsightly seams between bowl and vanity deck. Cultured marble shower panels are typically only seamed where panels meet in the corners.

How do I maintain a Cultured Product?
Because of the hard gel-coat surface and non-porous surfaces, it resists staining.

Care is very simple; Routine cleaning with a soft sponge or cloth or non-abrasive aerosol foam cleaner is all that is normally needed to give many years of trouble-free service. Harsh abrasive cleaners are neither required nor recommended, and never unse a scouring pad. Also don’t forget to use a squeegee on shower walls after each shower keeps the walls spotless! If you'd like, try some of the newest products on the market, such as Clorox Bathroom Cleaner with Teflon® or Tilex Fresh Shower Daily Shower Cleaner®. (Powdered cleaners should not be used).  Be sure you read and follow the manufacturer application directions carefully before using.
