Store and apply between 40ºF (4ºC) and 100ºF (38ºC). Always test plastic materials for compatibility when using solvent base products. Make certain this product is completely dry and the area free from solvent odor if food is involved. Not suggested for sealing vapor barrier jackets. Allow to dry to a solvent-free condition before installing weld pins. Overhead applications may require mechanical fasteners.
Spray, brush or roller.
