A water-based elastomeric, high-build acrylic coating for exterior stucco, masonry, concrete, and EIFS. Thorolastic repels wind-driven rain yet allows building interiors to breathe. It bridges crack movement up to 27 mils (at 73 ºF), and will retain its elastomeric properties over the years. Thorolastic comes in smooth, fine, and coarse textures. It is tintable to 48 "Elements" colors, and can be custom tinted. Thorolastic® is VOC compliant.
