Sea-L is a small 70 mL tube of Sika's multi-purpose marine polyurethane sealant, Sikaflex®-291i: a non-sag, 1-component sealant that cures on exposure to atmospheric moisture to form a durable elastomer. It makes elastic, vibration-resistant joint seals and bonds well to the materials commonly used in boat building, such as wood, metal, metal primers, 2-component paint coatings, ceramics and GRP. The handy tube size suits small repairs and bedding jobs.

Do not use on plastics prone to stress cracking, such as acrylic (PMMA) or polycarbonate (PC). Suitable for experienced professional users. Test on the actual substrates and conditions to confirm adhesion and material compatibility.
