Maston SpraySeal is an easy-to-use rubberized utility coating that stops and seals leaks instantly. It fills and seals leaks and cracks, providing a flexible water-tight seal that prevents moisture penetration, rust and corrosion. Its high-build and high viscosity formula is specifically developed to fill cracks, gaps, and holes while maintaining superior flexibility even with temperature changes, joints of different materials, and UV radiation. Maston SpraySeal contains almost triple solids compared to conventional products, allowing for quick sealing and a thick coating. It maintains its flexibility for use on metal, vinyl, plastic, PVC, concrete, and other surfaces year-round. It can be used on sunroofs, ventilations, drains, ductwork, gutters, and small foundation cracks. This versatile coating can be over-painted with any paint after drying.
