XS PRECAST

XS Precast™ is a dual component precast concrete bag mix that greatly reduces the materials and labor required to construct traditional precast concrete. No reinforcement steel is required, thinner precast pieces are routine, and quicker production times are accomplished. A stronger, denser and more flexible cementitious composite is created by combining cutting-edge technology with modern fiber advancements. With a wide range of coloring and texture selections along with the
addition of optional aggregate loading (up to 10 lbs per bag) design considerations are nearly limitless. XS-Precast produces concrete countertops, fireplace mantles and facades, shower surrounds, wall panels, furniture and many other architectural elements. XS Precast is the perfect medium for residential, commercial, and industrial applications.

XS PRECAST TEMPERATURE/DRY/CURE

Fabrication of XS-Precast should be inside a shop. Casting should take place when shop temperature and all materials are maintained between 50°F (10°C) and 90°F (32°C) throughout all fabrication and curing. Product will dry and cure slower at cool temperatures and conversely, faster at warm temperatures. Full cure is reached at approximately 30 days, like concrete. Although rare, at high altitudes and dry climates, some pieces may require covering with plastic to slow the cure and avoid curling.
