SpecPlug
Fast-setting hydraulic-cement mortar
SpecPlug is a fast-setting hydraulic cement mortar designed to instantly stop water flow through holes and cracks in concrete and masonry. It expands as it sets without shrinking or oxidizing, ensuring a durable repair.
- 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
Recommended Uses: 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:
- Enlarge cracks to at least 3/4 inch width and depth, cut square or undercut, avoiding a “V” shape.
- Remove all grease, wax, oil, and contaminants, including curing compounds.
- Saturate the surface with water but ensure no standing water remains.
Mixing:
- Combine a small amount of water with SpecPlug to achieve a putty-like consistency, using about 20%-21% water by weight.
- Mix only what can be used within 2 minutes, about 9.5 pints of water per 50 lbs of product.
Application Techniques
- For vertical and underwater applications, firmly hold the product in place until it sets, typically within 3 minutes.
- Adjust mixing water temperature to control the setting time based on ambient conditions.
Curing
- SpecPlug continues to gain strength if kept moist, with optimal strength achieved when wet cured for up to 2 days.
Packaging
- Available in 10 lb pails and 50 lb pails.
Shelf Life
- 18 months when stored properly in unopened containers in a clean, dry area between 45°F and 90°F.
