Buying Guide: Sealants and Adhesives

About the MasterSeal NP 1 Sealant
MasterSeal NP 1 is a one-component elastomeric polyurethane sealant that requires no mixing. It is gun grade and non-priming, and it typically bonds to many materials, including concrete and masonry, without a primer. Available colors include aluminum gray, black, limestone, medium bronze, stone, tan and white.

Choosing a Color or Adhesive
Pick the color that matches your surface or the color of your old sealant. Choose the MasterSeal NP 125 clear thermoplastic rubber adhesive when you need a clear bond rather than a sealant. Check the product name and the number on the package before you order.
