## Overview

SIKA Sikaflex-291 LOT is a black, one-component polyurethane marine adhesive and sealant designed for superior bonding on wood, fiberglass, and metal. It offers high elasticity, non-corrosive durability, and resistance to fresh and saltwater, acids, and oils. Its self-leveling formula cures with atmospheric moisture, allowing sanding and painting after 4 hours, making it ideal for professional marine and interior applications.

## 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.

## 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.
