NP1 Urethane Caulking

Regular price $ 10.70

NP 1 is a one-component, high performance, nonpriming, gun-grade, elastomeric polyurethane sealant. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry.

MDI recommends NP1 because it has proven to be so tough after it has been applied. It is about the only product that will adhere to the airform fabric over time.

It is an excellent sealant/bonding agent.
