ALDOSEAL 385 is a technologically advanced, high solids, single component moisture cure polyurethane elastomeric sealant. In addition, ALDOSEAL 385 is a brush grade sealant and an excellent all-purpose sealer to address roof leaks on most roofing substrates.
ALDOSEAL 385 is produced in an aluminum gray color that allows for faster cure times than white sealants, mil for mil. ALDOSEAL 385 provides greater protection against leaks and water penetration than most sealants due to its tenacious adhesive properties, higher tensile strength and low vapor permeability values. In summary, ALDOSEAL 385 offers a wider window of application than water based acrylic sealants.
ALDOSEAL 385 is specifically designed as a protective sealant during the detail phase of complete elastomeric roof coating restoration work. This product is formulated to seal fasteners and seams and penetrations on ametal roof systems, seams and penetrations on single plymembrane systems and fill cracks and voids on older BUR systems. In addition, ALDOSEAL 385 is an ideal all purpose sealant to quickly and permanently seal leak areas on virtually any roofing system.
