Sikaflex®-219 LM is a one-component, low-modulus polyurethane sealant. It adheres well to a wide variety of substrates and cures on exposure to atmospheric moisture. Sikaflex®-219 LM exhibits very good recovery and is ideal for sealing applications requiring high joint movement capability.

Sikaflex®-219 LM is suitable for joints subject to movement. Typical applications are sealing between logs in log homes, installation and perimeter sealing of windows and doors, and Exterior Insulation Finish Systems (EIFS). Sikaflex®-219 LM adheres well with the most common substrates in these applications such as metals, metal primers and paint coatings (2-component systems), and wood. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-219 LM on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
