Introducing the Capitol Tan Polyurethane Construction Sealant, a 10.1 oz cartridge designed for demanding building projects. This high‑performance sealant cures when it encounters moisture, forming a flexible, durable bond that resists sagging on vertical and overhead joints. Its neutral‑tan hue blends seamlessly with most exterior finishes, making it ideal for window frames, door surrounds, wall seams, floor edges, and balcony connections.
Benefits: The formulation delivers long‑lasting elasticity, protecting structures from cracking and water intrusion while allowing post‑application painting, staining, or sanding. Because it meets potable‑water standards, it can be safely used in wet environments and remains watertight even after permanent submersion.
Key Features & Benefits:
- Moisture‑Activated Cure: Reacts with ambient humidity to develop a resilient, rubber‑like seal that adheres to a wide range of building materials.
- Non‑Sag Vertical Performance: Engineered to stay in place on walls, ceilings, and overhead joints, eliminating run‑off and ensuring a clean, uniform bead.
- Paintable & Sandable Surface: Once cured, the sealant accepts topcoats, stains, and sanding, allowing seamless integration with surrounding finishes.
- Waterproof & Submersible: Certified for potable‑water applications and capable of withstanding permanent immersion without loss of integrity.
- Extensive Coverage: One tube delivers approximately 12.2 linear feet of 1/2″ × 1/4″ bead, reducing material waste and project time.
Why Choose This Sealant? Engineered to meet federal specification TT‑S 00230C, Type II, and ASTM C‑920 standards, this sealant offers industry‑tested reliability for commercial and residential construction. Its versatile performance, combined with a neutral tan color and easy‑apply cartridge, makes it a go‑to solution for architects, contractors, and DIY enthusiasts seeking a trustworthy, waterproof seal for every joint.
