Flex Seal Liquid Rubber Coating Sealant — Waterproof, Flexible, UV Resistant (Clear) | 1 Gallon

Overview

Flex Seal Liquid is a liquid rubber coating in a can that lets you brush, roll, dip, or pour a flexible sealant onto almost any surface. The result is a watertight, rubbery layer that moves with the material beneath it, helping you address leaks with relative ease.

Key advantages

• Goes on smooth and covers quickly, sealing out water, air, and moisture
• Flexible, breathable coating that expands and contracts with surfaces
• UV Resistant to help protect surfaces from sun exposure
• Chemical resistant with rust-inhibiting properties to guard metal and masonry

Real-world uses

From roof repairs to damp basements, and from RVs to boats, Flex Seal Liquid offers a versatile approach to protection. The clear version blends with most surfaces while delivering durable, flexible coverage, so you can choose visibility or discretion as needed.

Breathable yet protective, this coating helps shield substrates like metal, masonry, and EPDM without sacrificing surface appearance. It is designed to tolerate exposure to outdoor conditions while remaining flexible through temperature swings.

Performance and application

Practical benefits you may notice include faster drying times, a seamless barrier against moisture, and a coating that remains elastic as surfaces shift. Prep the surface, apply in thin coats, and allow each layer to cure before applying the next for thicker protection.

Usage notes

Always follow the product label for safety guidance and cure times. Results depend on surface condition and environmental factors. The clear option is ideal when preserving the appearance of substrates while delivering protection.
