Titebond WeatherMaster Ultimate MP Sealant 71092A 20oz Black Exterior

Description

Product Overview

The Titebond WeatherMaster Ultimate MP Sealant is a high‑performance, polymer‑based sealant designed specifically for exterior applications where durability and flexibility are paramount. Packaged in a convenient 20 oz black sausage tube, this sealant combines the strength of a polyurethane formulation with the elasticity of a hybrid polymer, delivering a permanent, crack‑resistant bond that can accommodate up to ±50% joint movement. Its advanced chemistry ensures excellent adhesion to a wide range of substrates, including PVC, wood, metal, concrete, masonry, stucco, glass, fiberglass, and many other common building materials. The sealant is UV‑stable, weather‑resistant, and maintains its flexibility over the life of the installation, making it an ideal choice for sealing windows, doors, shutters, exterior trim, metal and vinyl siding, gutters, vents, RVs, metal roofs, tractor trailers, and buses. With a proven track record of outperforming traditional silicone, tripolymer, and urethane sealants, WeatherMaster Ultimate MP provides reliable protection against water intrusion, air infiltration, and environmental wear.

Usage

Designed for professional contractors, maintenance crews, and DIY enthusiasts, this sealant excels in a variety of real‑world scenarios. Whether you are sealing the perimeter of a new window installation, reinforcing the joints of a metal roof, or repairing the seams on a trailer body, the 20 oz sausage pack offers precise control and easy application. The sealant can be applied directly from the tube using a standard caulking gun, allowing for smooth, continuous beads that fill gaps and joints of varying widths. Its fast‑set surface cure enables rapid handling, while the underlying polymer continues to cure, achieving full strength within 24 hours under typical conditions. For optimal performance, clean the substrate of dust, oil, and loose material, apply the sealant in a continuous bead, and tool the joint with a suitable tool or finger to ensure proper wetting and adhesion. The sealant’s black color provides a discreet appearance on dark substrates and blends well with most exterior finishes.
