Honeywell NP1SPBRZ12 Polyurethane Sealant 10.1 Oz

Product Description

The HONEYWELL NP1SPBRZ12 is a moisture-curing, single-component polyurethane sealant supplied in a 10.1 oz tube in Special Darker Bronze color. Previously marketed as Sonolastic NP 1, it delivers permanent elasticity and is formulated for high-performance sealing on active joints in both interior and exterior applications. Licensed contractors and trade professionals use it for expansion wall joints, floor and pavement joints, curtain walls, precast panel walls, window frames, structural connections, dams, spillways, and storm water drains. It bonds to concrete, masonry, aluminum, and wood without a primer and requires no mixing before application.

This sealant is suited for vertical and horizontal joints in residential, commercial, and civil construction settings. Typical applications include sealing precast concrete panel systems, masonry facades, and pavement control joints exposed to regular movement and moisture. The Special Darker Bronze color matches common bronze-tone window frames and architectural finishes. It handles joint movement capability of plus or minus 35 percent, making it appropriate for dynamic joints subject to thermal cycling or structural deflection.

Installation Notes

Application is typically performed by licensed contractors or experienced tradespersons familiar with sealant joint design and surface preparation standards. Substrate surfaces must be clean, dry, and free of dust, oil, and loose material before application. Follow applicable building codes and manufacturer surface-preparation guidelines for joint width-to-depth ratios to ensure proper adhesion and movement performance. Do not apply this product to surfaces that are continuously submerged or to joints where movement exceeds the rated plus or minus 35 percent capability.
