Resysta looks like natural wood but is comprised of 60% rice husk, 22% common salt, and 18% mineral oil. The resulting material is splinter-free, rot-free, and fade and skid resistant, even in extreme weather. Available in its natural form, Resysta can also be treated with water-based formulations for a custom stain. Ideal for decking, exterior cladding, rooftops, and balconies, Resysta planks and panels can be cut, drilled, sanded, and refinished just like regular wood.
