Coverage & How Much You Need

Coverage depends on bead size, joint width, joint depth, backer rod, and waste from tooling. Ace Hardware lists this item at about 26 linear ft coverage, but field yield can vary. For larger jobs, calculate linear feet from the joint dimensions and add waste for tooling and startup cuts.

Compatibility / Fitment

Use on compatible clean, dry construction substrates according to the current MasterSeal NP1 technical data sheet. Verify primer requirements, backer-rod depth, joint movement, paint or coating compatibility, cure time, and whether polyurethane chemistry is acceptable before substituting for silicone or acrylic sealants.

FAQs

Is this priced as one tube or a case?

This offer is priced per 10.1 oz white tube. Some suppliers use carton-order multiples for procurement, but the sell unit here is one tube.

Does model NP1WHT12 match this single 10.1 oz tube?

Yes. Public retail references list NP1WHT12 with UPC 080492301441 for the BASF MasterSeal NP1 white 10.1 oz tube. Some listings note ordering in multiples of 12, but the model is still tied to the 10.1 oz tube item.

Is NP1 a silicone sealant?

No. MasterSeal NP1 is a one-component polyurethane sealant. Do not substitute it for silicone where the system specification requires silicone chemistry.

Where is this sealant commonly used?

It is commonly used for compatible concrete, masonry, window and door perimeters, flashing details, penetrations, roof-adjacent details, and construction joints where an elastomeric polyurethane sealant is specified.

What should I verify before ordering?

Confirm color, tube size, model NP1WHT12, substrate compatibility, primer requirements, joint depth, backing material, cure time, and the quantity needed for your bead size and linear footage.

Sealants must be installed on properly prepared substrates and within the manufacturer’s joint-design limits. Follow the current MasterSeal NP1 technical data sheet, safety data sheet, and job specifications.

Product Expert Notes

Choose this product when the job calls for a white 10.1 oz one-component polyurethane sealant with MasterSeal NP1 performance. The model/UPC evidence matches the single-tube item; use carton or order multiples only as procurement planning, not as the customer-facing sell unit.
