Thum-Gum is a non-curing, water-resistant com pound formulated to prevent the entry of moisture, dust, and air into the joint, seam, or other opening that is being sealed. This material is applied by hand and is very pliable to allow for easy manipulation into tough openings. This durable material adheres to and seals most clean substrates such as wood, metal, plastic, and glass without cracking, drying, or shrinking.
