PlasterMax for applications over EPS foam to replace Gypsum board with a fire rated abuse resistant barrier

PlasterMax replacing Gypsum Board

GigaCrete building products are NON COMBUSTIBLE

While the PlasterMax interior veneer plaster system provides the ultimate in finishing of ICF construction, its application over EPS insulation sheets, energineered panesl such as cement or fiberboard, monolithic concrete and unit masonry, offers unique advantages to these conventional all systems as well. Important product performance features include: superior fire resistance, 0 flame spread and 0 smoke developed, no VOC emissions, extreme abrasion and improved indent resistance superior to abuse resistant gypsum board and high resistance to mold and mildew.

The new concrete matrix does not use Portland cement, sand or gravel but instead a proprietarty nontoxic polymer binder. Additional fillers include waste paper, cardboard, plastics, Styrofoam packaging, recycled glass, sludge from paper mills and agricultural waste fibers. The recycled materials are mixed with GigaCrete's own mineral cement formulation, which requires less water and yields less carbon dioxide in production than cement. Most of these materials would end up in a landfill instead they make a great alternative Green Building Product. It is mixed like concrete with dry ingredients but with very little water. Normal concrete requires up to 28 days for adequate curing but GigaCrete products sets solid in 4 hours and is usable in 8 hours. It is less expensive building solution due to the speed of construction and therefore labor savings.
