Uses

• Stopping active water leakage through concrete and masonry surfaces.
• Preventing water seepage through cracks, seams and floor-to-wall intersections.
• Stopping leaks in basements, foundations, sewer pipes and manholes.
• Emergency repair of ruptured water pipes, damaged boat hulls and similar surfaces.
• Water-stopping repairs in swimming pools, cisterns, troughs and silos.
• Repairs in sewers, tunnels, elevator pits and electrical vaults.
• Sealing wet surfaces and areas exposed to continuous water pressure.
• Anchoring steel bolts and other metal fixtures where immediate use is required.

Advantages

• Rapid-setting hydraulic cement-based mortar.
• Stops running water and active leakage.
• Excellent bond strength after prolonged contact with water.
• High early compressive and flexural strength.
• Suitable for horizontal, vertical and overhead applications.
• Can be applied across a wide range of thicknesses.
• Non-shrink and highly durable.
• Can be mixed with water or used as a dry powder in specific applications.
• Suitable for underwater use.
• Easy to handle and does not require special application tools.
• Single-component, ready-mixed product.

Substrate Preparation

All surfaces must be sound, clean and free from dust, cement laitance, loose particles, grease, oil and any contaminants that may reduce adhesion.

Wire brushing, sandblasting, water blasting or grinding may be used to clean and prepare the substrate.

Where moss, algae or similar biological growth is present, treat the area with a suitable proprietary biocide after grit blasting.

Open cracks and fissures sufficiently to provide an appropriate recess for receiving PLUG. For good mechanical anchorage, form a square or preferably dovetail-shaped groove. Avoid forming a shallow V-shaped groove.

Mixing

1. Mix only a small quantity that can be applied immediately.
2. Use approximately 0.30 kg of clean water for every 1 kg of PLUG powder at 23°C.
3. Place the measured clean water in a suitable container.
4. Add the powder rapidly to the water while mixing.
5. Mix for approximately 15 seconds until a uniform, workable consistency is obtained.
6. Use the material immediately because it sets in approximately 90 seconds at 23°C.
7. Use lukewarm water in cold weather.
8. Use cold water at elevated temperatures.
9. Do not remix or add water after the material begins to set.

Application: Stopping Active Water Leakage

1. After mixing, form the material into a plug using rubber-gloved hands.
2. Hold the material until a slight increase in temperature is felt.
3. Press the plug firmly into the crack, hole or joint.
4. Do not twist or excessively work the material during placement.
5. Maintain firm pressure until the material has set.
6. Remove excess material using a suitable trowel.

Dry-Powder Application

In suitable circumstances, PLUG may be applied as a dry powder. Place and hold the powder directly over the active leak for approximately 40–50 seconds.

Floor-to-Wall Joints

1. Open a groove approximately 30 × 30 mm along the internal corner.
2. Prepare and apply PLUG inside the groove.
3. Form the material into a continuous cove at the wall-to-floor intersection.
4. Keep the repair damp for at least 15 minutes after setting.

Anchoring Bolts and Metal Fixtures

1. Drill the hole to the depth specified by the project designer.
2. Provide a gap of at least 10 mm around all sides of the bolt.
3. Clean the hole and remove dust and loose particles.
4. Position the bolt centrally inside the hole.
5. Press PLUG firmly around the bolt without leaving voids.
6. Keep the applied material moist for at least 15 minutes.
7. Do not apply loads or pressure before the material has cured sufficiently.

Cleaning

Remove PLUG from tools and equipment immediately after use and before initial setting using clean water. Hardened material must be removed mechanically.

Storage and Shelf Life

PLUG has a shelf life of 12 months when stored in its original sealed packaging in a dry, shaded place under suitable warehouse conditions at a temperature below 35°C.

Packaging

• 4 kg containers.
• 25 kg containers.

Health and Safety

• Wear suitable protective gloves and safety goggles during mixing and application.
• Avoid unnecessary contact with the skin and eyes.
• In case of skin contact, wash immediately with soap and clean water.
• In case of eye contact, rinse immediately with plenty of clean, cold water.
• Seek medical advice if irritation continues.
• The product is non-flammable and is not classified as hazardous under current legislation.
• Do not dispose of the material in water or soil. Follow applicable local regulations.
