Available in white, black, and grey, it is low-odour and low-VOC, making it safe for indoor use and overpaintable for a flawless finish.

## Description

Product Description Looking for an easy-to-apply, low-odour marine sealant? Sikaflex 291i Multifunctional Adhesive Sealant, with its non-sag 1-component polyurethane formula, is ideally suited for boat applications. With Wheelmark approval for safety at sea and a solvent-free, low VOC and low-irritation formula, it's the multipurpose adhesive and sealant you need for your marine repairs. Apply using a cartridge gun, and it will form a skin in 60 minutes before curing completely in ambient moisture to a seawater-resistant finish in 24-48 hours. It bonds well to most marine materials, including wood, metal, ceramics, plastics and more. Plus, you can overpaint it once dry. Also available in Grey and Black.
