Flex Seal 14 oz White Spray — 2-Pack Waterproof Rubber Sealant for Gutters, Roofs, RVs & More

Overview

Flex Seal comes in a convenient 2-pack of 14 oz white spray cans, designed to help you tackle leaks quickly across a range of surfaces. The formula seeps into cracks and gaps, then dries to a flexible rubberized coating that stays pliable over time. Once cured, the surface can be painted to match your project, offering a seamless finish without bulky replacements.

Why this sealant works

The coating penetrates into crevices and holes to form a durable barrier against moisture. Its flexible nature allows it to move with temperature changes, reducing the risk of future cracks or peeling. Engineered to resist sagging in hot weather and cracking in cold, it aims to provide year‑round protection on exterior surfaces.

• Seals leaks with a watertight, flexible rubber coating
• Paintable after drying to blend with any color scheme
• Works on wet or dry surfaces for versatile repairs
• Resists sagging in heat and cracking in cold for long‑lasting use
• Suitable for gutters, wood, RVs, campers, roofs, skylights, windows, and more

Real‑world uses

From gutter seams to roof patches, this sealant provides a quick barrier against moisture. It adheres to common outdoor materials and creates a protective layer that can be repainted to suit your aesthetic goals, making it a flexible option for ongoing maintenance.
