Applications & Uses
- Applications
- Uses
MS Gunnite is ideal for use on:
- Rock stabilization projects
- Pool construction
- Parking decks
- Tunnels
- Dam repair
- Retaining walls
- Bridge structures
- Water treatment plants
- Piers and docks
- Application
Surface Preparation:
All surfaces in contact with MS Gunnite shall be free of dirt, oil, grease, laitance and other contaminants that may act as bondbreakers. All unsound concrete should be removed to ensure a good bond. ACI recommends the area to be patched should be saturated for 24 hours before placement. Remove any standing water. Surface should be saturated, surface dry (SSD). Always apply a test patch. Maintain contact areas between 40°F (4°C) and 90°F (32°C) prior to repair and during initial curing period.
Yield:
50 lbs (22.7 kg) will fill approximately 0.43 ft³ (0.012 m³) when 4.0 quarts mixing water is used.
Coverage:
One 50 lb (22.7 kg) bag will cover approximately 6 ft² at 1/2” thickness. Coverage may vary depending on porosity of surface.
MS Gunnite is designed to be used with dry-process equipment and should be mixed directly at the gun. Adjust water at the nozzle for required consistency.Placing:
MS Gunnite should be placed using established procedures according to ACI 506 “Recommended Practices for Shotcreting.” Be sure not to over water. Material is best applied at an angle of 90° from a distance of 2–6 ft from the area of application. MS Gunnite can be effectively applied at depths of 1/2–6” in one lift. If multiple lifts are necessary, score surface to a rough texture and apply second lift after first lift has hardened.
Mixing:
MS Gunnite is designed to be used with dry-process equipment and should be mixed directly at the gun. Adjust water at the nozzle for required consistency.
Finishing & Curing:
Follow standard ACI curing practices. Exposed surfaces should be cured with a membrance forming curing compound such as US SPEC Maxcure Resin Clear, US SPEC Hydrasheen or US SPEC Hydrasheen 30%.

Technical Details & Test Data
- Limitations
Do not apply when the surface or ambient temperature is below 40°F (4°C) or expected to fall below 40°F (4°C) within 48 hours. Do not apply over surfaces that are frozen or contain frost. Do not apply over any active faults or cracks in the substrate without addressing any movement that may occur. Allow concrete to fully cure for 28 days before use of this product. All repairs should have a minimum depth of 1/2”. Setting time will speed up in hot weather and slow in cold weather.
