Product Description
Sikaflex 1A is a high-performance, moisture-cured, one-component polyurethane elastomeric sealant engineered for a wide range of construction joint applications. Its non-sag formula allows for easy application in both vertical and horizontal joints, including small joints, fillets, windows, door frames, roofing details, and submerged conditions such as canals and reservoirs. Sikaflex 1A bonds effectively to most construction materials without the need for a primer, simplifying the sealing process and saving time on the job site.
This sealant can be applied to green concrete as soon as 24 hours after pouring and to damp surfaces just one hour after exposure to moisture. It cures to a tough, flexible consistency with excellent cut and tear resistance, accommodating joint movement of approximately ±35%. Sikaflex 1A is resistant to aging, weathering, jet fuel, and is non-staining, ensuring long-lasting durability in a variety of climates and environments.
Certified to NSF/ANSI/CAN 61 for potable water applications, Sikaflex 1A is safe for use in sensitive environments. It features fast tack-free and final cure times, eliminating the need for mixing, pre-heating, or specialized equipment, which enhances efficiency on the job. Additionally, it is paintable with water-, oil-, and rubber-based paints, allowing for aesthetic customization.
Available in multiple packaging options, Sikaflex 1A provides a reliable, flexible, and durable sealing solution trusted by professionals for construction and repair projects requiring high-quality joint sealing performance.
