## Overview

SIKA Sikaflex-291 LOT is a black, one-component polyurethane marine adhesive and sealant designed for wood, fiberglass, and metal surfaces. It offers high elasticity, water resistance (fresh and saltwater), and vibration resistance, curing fully in 24 hours. Ideal for above and below waterline applications, it can be painted and sanded post-application, making it a versatile, durable choice for professional marine and interior sealing needs.

## 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.

## Features

- IDEAL FOR MARINE APPLICATIONS — Sika 291 adheres to material commonly used in marine construction, such as wood, fiberglass, metal, and metal primers and paint coatings. Use above or below water line
- VERSATILE AND DURABLE — It is non-corrosive and highly elastic making vibration-resistant joint seals on decking and can be used in an array of interior contexts
- FORMULATED FOR PERFORMANCE — This one-component polyurethane marine-grade sealant cures upon exposure to atmospheric moisture. The black sealant can be overpainted and sanded without loss of stability
- RESISTANT TO BOTH FRESH AND SEAWATER — Will also resist diluted acids and caustic solutions. Provides temporary resistance to fuels, mineral oils, and vegetable and animal fats
- EASY APPLICATION — Use a manual, pneumatic, or electric-driven piston gun to apply this one-component polyurethane paste. Surface should be clean and dry prior to application for optimal performance

## Questions & Answers

**Q: Will this work to repair cracks in my pool skimmer? Is it elastic or hard like epoxy when cured?**
A: It is elastomeric and should work well for that I would think.  I used it to seal the roof seams on a 2015 GMC pickup and it worked great.  Keep in mind it is self leveling so it spreads out a bit on its own.

**Q: Would this work for adhering rubber matting to a wooden and aluminum boat deck?**
A: yes, it would work. A permanent solution would be 3M 5200 sealant. Try a small piece first!

**Q: can i use this to attach solar panels to camper roof? pnls weigh 24pnds.**
A: I used mine for water proofing sealant while glueing down a metal flang which weighed very little. Not sure about the solar panels

**Q: Would this work in a swimming pool.  I have a concrete pool that has plexiglass windows in the sides below the water level.**
A: I believe so, we use it on the seams of our water slide that's underwater at all times.
