Flex Seal Liquid – Waterproof Flexible Rubber Coating (16 oz)

Overview

Flex Seal Liquid is a liquid rubber coating you can apply by brush, roll, dip, or pour. It creates a flexible, seamless layer that moves with temperature and weather rather than cracking or peeling, helping you tackle leaks with less downtime.

When you need a durable, watertight seal, this coating lays down as a smooth shell that resists water, air, and moisture intrusion. It also offers UV resistance and general chemical resilience, helping surfaces stay protected through sun exposure and common environmental challenges.

What it does

• Watertight, flexible rubberized coating that stretches and contracts with the surface
• Goes on smoothly and covers quickly to reduce application time on irregular surfaces
• Seals out water, air, and moisture to help keep interiors dry
• UV resistant to minimize sun-related wear and color fading
• Rust and corrosion resistance on metal surfaces; chemical resistant for common exposures

Where to use

• Roofs, basements, EPDM rubber roofing, and masonry surfaces
• RVs, campers, trailers, and marine exterior areas
• Concrete, brick, and other exterior substrates needing a flexible seal

Application versatility is a key benefit: brush for precise edges, roll for larger areas, dip for shapes with openings, or pour to cover quickly. This 16 oz can is designed for convenient storage and handling, making it a practical option for DIY repairs.

For best results, prepare the surface by cleaning and drying it thoroughly, and follow the manufacturer’s guidelines. Drying and recoating times will vary with temperature and humidity, but the coating is designed to cure into a resilient, flexible barrier that can adapt to surface movement over time.
