SpecPlug Fast-Setting Hydraulic-Cement Mortar

• Single-component, easy to use by just adding water.
• Expands to form a strong, watertight bond to the substrate.
• Sets in approximately 3-5 minutes, rapidly stopping flowing water.
• Suitable for both vertical and underwater applications.
• Certified to NSF/ANSI Standard 61 for safe contact with potable water.

Application

SpecPlug is suitable for:

• Basement and masonry cracks
• Floor and wall joints
• Manholes and sewer pipes
• Tunnels and swimming pools
• Below-grade foundations

Surface Preparation

• Enlarging Cracks: For best results, enlarge the crack to at least 3/4″ in width and depth, ensuring a square or undercut shape.
• Cleaning: Remove all grease, wax, oil, contaminants, curing compounds, and any weak, contaminated, or deteriorated concrete from the substrate.
• Wetting Surface: Saturate the repair area with water. SpecPlug can cure in the presence of running water, making it ideal for active leaks.

Mixing and Application

• Mixing SpecPlug:
  • Create a putty-like consistency by adding a small amount of clean water to SpecPlug. Aim for a 20%-21% water-to-product ratio by weight.
  • Mix only enough material that can be placed within 2 minutes.
• Application Procedure:
  • For vertical and moving-water applications, hold the mixed SpecPlug firmly in place until it sets, typically within about 3 minutes.
  • Adjust water temperature to manage the setting time: use hot water and warm material in cold conditions, and cold water in hot conditions.

Curing

• Curing: Keep SpecPlug damp for at least 30 minutes to support curing. Optimal strength is achieved through wet curing for up to 2 days.
