Flex Seal Liquid is designed to bond to a wide range of surfaces, but clean, dry surfaces are ideal for a successful application. If you're tackling a repair in early spring or after snowfall, it's important to understand how moisture affects Flex Seal Liquid's performance.

Why Moisture Matters

• Melting snow can interfere with adhesion and compromise the integrity of the seal.
• Damp surfaces prevent Flex Seal Liquid from properly bonding to porous materials.
• Moisture may create bubbles or uneven curing, especially in cooler temperatures.
• Water trapped beneath the coating could affect the product's long-term durability.

While Flex Seal Liquid is super-strong once cured, it needs the right conditions to form a powerful bond. Taking the time to let surfaces fully dry before application helps ensure long-lasting protection you can count on season after season.
