Underwater & Wet Surface Epoxy Leak Repair Coating
Industrial-grade two-part epoxy designed to stop leaks in cooling towers, water tanks, troughs, and any water-holding structure. Applies directly to wet or submerged surfaces — no shutdown required.
Applies Underwater • No Primer Needed • Concrete & SteelStop Leaks Without Shutting Down
This coating is a huge time and money saver for owners of large cooling towers, swamp coolers, troughs, and water tanks. While originally designed to stop leaks in the basins of cooling towers, it can be used wherever there is a water leak below the water surface of any type of apparatus or structure.
Adheres to concrete or steel surfaces with no primer necessary. Can be applied to surfaces that are wet or underwater, and works on both horizontal and vertical surfaces. Eliminates the need to shut down mission-critical equipment and costly replacement of cooling tower basins and structural parts.
Patch compound option: Mix with Silica Flour/Sand for a pastier consistency when repairing larger cracks or holes. Coverage will be reduced when used as a patch compound.
Coverage & Specifications
Available colors: Light Gray, Medium Gray, Dark Gray, and White.
Coverage varies by application: Horizontal surfaces: 80–200 sq ft/gal depending on application. Vertical surfaces: 250 sq ft/gal. Two coats required for both. Less coverage when used with Silica Flour/Sand as a patch compound.

Application Instructions
Mixing
Mix Part A & Part B in a 3:1 ratio with a Jiffy Mixer on low speed or with a large paint stirring stick for 2.5 minutes.
Do not mix more than you can apply in 20 minutes. This is a fast-setting epoxy β work in manageable batches.
Surface Preparation
Surface to be coated should be free of any mold, mildew, algae, or loose flaking rust. This coating will adhere to concrete and steel with tight rust, wet or dry. Can be applied to basins that are still full of water.
Application
Apply with a good quality stiff brush, lint-free roller, or putty knife.
Underwater cure: Will cure underwater in 6 hours at 75Β°F. Colder temperatures will require longer cure times.
Patching Large Cracks & Holes
Mix with Silica Flour for extra thick patching and apply with putty knife. If sealing drain pans or water basins with wide cracks that are open underneath, provide a backstop to prevent material from sagging for best results.
Small repairs: Coating is very thick and will bridge small holes and cracks without the need for backstopping.
Second Coat
Allow first coat to cure to a rock hard finish, then apply the second coat.
Do NOT let more than 24 hours pass before applying the second coat.
Ideal Applications
Ideal for pilings: Coating can be applied at low tide and will cure underwater during high tide. No need to wait for dry conditions.
