## Overview

Sika Sikaflex-291 LOT is a premium black polyurethane marine-grade adhesive and sealant designed for superior bonding on wood, fiberglass, and metal surfaces. It offers elastic, non-corrosive, and vibration-resistant seals that cure fully in 4 hours, are paintable, sandable, and resistant to fresh and seawater, acids, fuels, and oils. Ideal for professional marine and industrial applications, it ensures durable, clean, and efficient sealing with easy application via various piston guns.

## Description

If you need a marine-grade sealant that creates a strong, secure bond with a wide array of surfaces commonly found in marine applications, Sikaflex-291 LOT's black sealant is the ideal choice. It's specially designed for use where a long working time is needed, and cooler temperatures can extend the curing period. The typical skinning period is four hours, after which it can be painted for a more professional finish. Sikaflex-291 LOT is a self-leveling marine grade sealant, so you won't need to tool it down for an even surface. 10.1 fl. oz. cartridges fit conveniently on a variety of piston guns.

Review: As expected - Works good.
Review: Easy to apply, looks like a good seal - I used it to seal between the body and the bottom pan of a 1970s VW Beetle I'm rebuilding. It'll take me months to find if the seal provided by this product is durable. But for now, it looks encouraging. Also, it is rated for "below the waterline", and that should be more than sufficient overkill for a Volkswagen. As I had to apply the sealant from below the car, it dripped a little bit but not badly. The product flows into place readily and can be smoothed, like caulk, with a gloved (!!!) finger. Go without gloves and have a very messy clean-up coming. The product dries to a deep glossy black. As it is paintable, I plan to spray the bottom of the car with undercoating for protection. The seals cured overnight and look confidence-inspiring.

### ⭐⭐⭐⭐⭐ Oh yeah
*by G***T on October 5, 2025*

Grabbed some rubber to make a cover for the saildrive port on my sailboat; it keeps barnacles out. I wasn't expecting this to hold at all for months underwater and under sail. Still there six months later. I am amazed.
