Flex Seal Liquid Clear 32 oz – Waterproof Rubber Coating Sealant

Overview

Flex Seal Liquid Clear 32 oz is liquid rubber in a can, designed to transform surfaces with a simple brush, roll, dip, or pour. When applied, it forms a flexible, weatherproof film that remains pliable as it cures, giving you a versatile coating for a range of needs without a heavy, time consuming process.

What it does

This clear coating acts as a watertight seal that blocks moisture while allowing the surface to breathe. It adheres to many materials and dries to a smooth finish that helps reduce drafts and air leakage. The product is UV resistant, which helps protect the coating from sun exposure, and it carries chemical resistance that can help fend off corrosion on treated surfaces.

• Goes on smoothly and covers quickly for a consistent finish
• Breathable coating that helps manage moisture behind the film
• UV resistant to limit sun damage and extend coating life
• Chemical resistant, helping to guard surfaces from common cleaners and solvents

Key benefits you may notice

Application tips

Flex Seal Liquid can be brushed, rolled, dipped, or poured onto clean, dry surfaces. For best results, apply in thin, even coats and allow sufficient drying time between layers. A single, well‑applied coat can deliver a durable, flexible seal that remains resistant to moisture and sun exposure over time. The product’s clear finish helps maintain the appearance of surfaces while still delivering protection.

Note: performance can vary by surface type, weather conditions, and preparation. Results are best when surfaces are clean and dry prior to application.
