Coverage & How Much You Need
Coverage depends on bead size and joint geometry. For estimating, calculate linear feet from the joint width and depth, include waste for tooling, and confirm carton/order multiples if the job requires full-case ordering.
Compatibility / Fitment
Use on compatible clean, dry construction substrates according to the current MasterSeal NP1 technical data sheet. Verify primer requirements, joint backing, movement needs, paint/coating compatibility, cure time, and whether polyurethane chemistry is acceptable for the assembly before substituting for silicone or acrylic sealants.
