Product Details

In an industry where toxins are the norm, Vermont Natural Coatings has found a better way. Unlike most sealants that sit on the surface and wear away quickly, requiring reapplication every year or two, Dynaseal uses nanotechnology to penetrate deep into the substrate. This creates a breathable, flexible barrier that becomes part of the cellular structure, preventing water from seeping in while allowing moisture to escape. Dynaseal Multi-Surface Sealer is an innovative new product for a changing world, one that places renewed importance on our future. Vermont Natural Coatings: delivering coatings that are safe for people, pets and the planet.
