STOP GUTTER JOINT LEAKS
Four reasons to seal
before the next storm.
Spray directly on joints
The trigger spray applies watertight sealer directly into narrow joints, even in hard-to-reach gutter corners.
Stop dripping joints
A seamless cured seal prevents costly water stains and protects your building walls from constant drips.
Long-lasting barrier
The durable cured protective layer resists water flow and weathering for long-term protection.
Engineered for outdoors
A flexible, weather-resistant sealant that adheres firmly to clean gutter surfaces season after season.
LEAKING GUTTERS DAMAGE WALLS
Water drips from unsealed corners.
A tiny gap in your gutter joint might not seem like a big deal. But every time it rains, water drips down the side of your building, soaking into the walls. Over time, this creates ugly water stains, cracks, and even structural damage. Instead of paying for expensive wall repairs, seal the joint at the source before the damage spreads.
SPRAY DIRECTLY ON JOINTS
A watertight seal in narrow gaps.
The convenient trigger spray lets you apply the sealant with precision, even into narrow gutter joints. Once cured, it creates a seamless, rubbery barrier that prevents water from seeping through. No more messy caulk tubes or complicated tools—just point, spray, and let it dry.
ENGINEERED FOR OUTDOOR SEALING
Built to face the elements.
This flexible, weather-resistant sealant adheres firmly to clean gutter surfaces. The standard-size container provides ample sealant for multiple joint repairs, making it ideal for patching up a whole season's worth of gutter maintenance in one go. It resists water flow and weathering, giving you peace of mind every time it rains.
THREE SIMPLE APPLICATION STEPS
Easy three-step process.
Hassle-free gutter joint sealing in minutes.
1. Clean
Clean the gutter joint thoroughly and ensure the surface is dry before application.
2. Spray
Aim the trigger spray directly into the joint and apply an even coat of sealant.
3. Cure
Allow the sealant to cure completely to form a watertight, weather-resistant barrier.
