Sika 515310 Polyurethane Construction Sealant 10.1 Oz

Product Description

The SIKA 515310 is a commercial-grade, ready-to-use polyurethane construction sealant designed for sealing cracks, joints, and penetrations in a wide range of building assemblies. It comes in a 10.1 oz cartridge and cures to a permanently elastic, flexible consistency that resists cutting, tearing, aging, and weathering. The sealant will not harden or shrink over time. It is paintable, sandable, and stainable after full cure, making it suitable for finish-critical applications. The dark bronze color blends with common architectural finishes. Installation is typically performed by general contractors, glaziers, waterproofing specialists, and skilled trade professionals working on commercial or residential construction projects.

This sealant is used for sealing construction joints, doors, windows, siding, roofing, gutters, sills, thresholds, basements, vents, skylights, wall penetrations, and precast panels. It bonds to most common building materials including concrete, wood, brick, aluminum, steel, glass, tile, marble, stone, and etched PVC. The formulation also seals out radon gas, making it applicable in below-grade and foundation assemblies. One 10.1 oz cartridge yields approximately 24 linear feet of coverage at a 1/4 inch bead width.

Installation Notes

Apply using a standard caulking gun to clean, dry, and dust-free surfaces. Fresh uncured sealant should be cleaned up immediately with a cloth; cured material requires paint thinner or another approved solvent for removal. Follow all applicable building codes and manufacturer surface-preparation requirements before application. Do not apply to wet surfaces or in conditions outside the recommended temperature range stated on the product packaging.
