Choose the Sealant by the Finish the Job Requires.
Exterior joints need weather resistance, adhesion, flexibility, and a finished appearance. Origin Pro gives contractors two clear paths: HP3 for 100% silicone sealing and HP4 for paintable hybrid-polymer sealing with color coordination.
Two Exterior Sealant Technologies. Two Clear Jobs to Do.
Start with the finish requirement. Choose HP3 when the job calls for 100% silicone waterproof sealing. Choose HP4 when the exterior joint needs a paintable hybrid sealant, professional tooling, and color confidence.
100% Silicone
Use HP3 when flexible waterproof silicone performance is the primary requirement and the joint will not be painted.
Recommended: HP3
Paintable Exterior Joints
Use HP4 for siding, trim, perimeter joints, and other exterior details where paintability and professional appearance matter.
Recommended: HP4
Color-Matched Finish
Use HP4 when the sealant needs to coordinate with siding, trim, windows, doors, and other finished exterior materials.
