Match the Look of Natural Stone

Thermocromex is able to duplicate the look, color, and texture of almost any natural stone, precast stone, and precast concrete with savings in excess of $25 - $150 per square foot. The image at left shows Thermocromex matched against a piece of Austin stone.

Match the Look of Precast Stone

With the permanent durability of natural stone and multi colored finishes, Thermocromex is a great alternative for budgets. Featuring color pigments that are alkali and UV-resistant blended right into the premix, it never needs recoloring. The image at left shows how Thermocromex is able to match the look of precast stone.

Custom Coloring

Some of the most popular patterns are multi-colored finishes which allow for natural color variation that is inherent in most stone. Unlike other products that utilize colored water or washes which easily fade over time, a micronized version of Thermocromex is used, utilizing only non-fading powdered pigments ensuring that the original appearance is unchanged 100 years later. With a wide range of standard colors available, custom coloring is always an option.

Custom Scoring

The image at left shows just a few of the scored joints that can be achieved and are commonly used for design aesthetics in creating block panels, chamfered stone, day joints, and brick patterns. The depth of the block joints can vary from 1/16 Inches up to 1.5 inches. The method used to create a block joint is achieved without the use of any power tools.
