Collection: Exterior Sealants
Legacy Pro exterior sealants are engineered for the demanding conditions of real jobsites — delivering weatherproof protection, UV stability, flexibility, and long-term adhesion on today’s most common siding, window, and trim materials.
Our exterior lineup includes HP3 100% Silicone for glazing and high-exposure joints, and HP4 Hybrid Polymer for multi-substrate siding and trim installations. Both formulations withstand harsh weather, accommodate building movement, and deliver the durable, long-lasting performance professionals rely on.
