PRODUCT OVEVIEW: The professional VapArrest S-135 system is designed to reduce water vapor transmission through concrete. When applied as recommended, the system will reduce water vapor transmissions up to 75% in areas with vapor transmissions as high as 12 lb./1000 sf/24 hrs. Using VOC free technology, this two-part epoxy system is easily applied with a medium nap paint roller in a 6 mil thickness and dries to full cure within 24 hours. A film thickness gauge is provided with each unit to assist in application at the proper spread rate. The design of VapArrest S-135 allows it to be applied after all floor preparation is complete including leveling, flattening and patching of the concrete.
