duoMatrix™ NEO can be used to make lightweight pieces that are very strong and water-resistant. NEO has received a flame rating of UL-94V-O and meets the ASTM E-84, Class A (or 1) flame rating for building materials, which means this product meets the highest standards for both flame and smoke.

Applications include making architectural elements, reproducing sculpture and creating theme effects. Coloring material is possible by adding concrete iron oxide powder pigments. Metal powders (bronze, pewter, brass, etc.) can be added to give the look of real metal castings at a fraction of the cost. You can duplicate the look of marble or ceramic by adding inexpensive fillers. Crushed stone can be added to simulate the effect of carved stone (sandblasting or abrading required).

PRODUCT MAY FREEZE IN TRANSIT – order may be delayed due to freezing temperatures.
