To use this Thermal-Grip® prong washer, first pre - spot the prongs into the rigid insulation. Then, use Grip - Deck screws or fasteners to attach the insulation to the surface. Make sure the washer flattens well on the insulation surface. When using, keep in mind that it's been tested for specific insulation materials like DuPont Thermax, Rmax ECOMAXci, etc., so use it only as recommended. During construction, since it has UV - resistant additives, it can withstand some exposure, but try not to leave it under the sun for an extremely long time. For maintenance, there's not much needed. Just keep it in a dry place when not in use. If the washer gets dirty, you can clean it with a mild soap and water solution. This product is made in the USA and approved by major insulation manufacturers, so you can trust its quality.
