Super SpecPlug
Fast-setting hydraulic-cement mortar
Super SpecPlug is a super fast-setting hydraulic-cement mortar that instantly stops flowing water through holes and cracks in concrete and masonry surfaces. This product does not shrink or oxidize, ensuring durable, watertight repairs.
- Single-component; simply add water.
- Expands as it sets, ensuring strong bonds and watertight repairs.
- Sets in about 90 seconds, rapidly stopping water flow.
- Certified to NSF/ANSI Standard 61 for potable water contact.
Application
Recommended Uses: Super SpecPlug is ideal 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″ width and depth, cut square or undercut; avoid “V” shape cuts.
- Clean the substrate thoroughly to remove grease, wax, oil, and other contaminants.
- Saturate the surface with water, ensuring no standing water remains.
Mixing:
- Mix Super SpecPlug with a small amount of clean water to achieve a putty consistency.
- Use approximately 20%-21% water by weight; about 9.5 pints of water per 50 lbs of product.
- Mix only what can be used within 2 minutes.
Application Techniques
- For vertical and moving-water applications, maintain firm pressure until final set (about 3 minutes).
- Adjust water temperature to manage setting times based on ambient temperatures.
Curing
- Super SpecPlug continues to gain strength as long as it remains damp.
- Optimal strength achieved when wet cured for up to 2 days.
Packaging
- Available in 50 lb (22.7 kg) pails.
Shelf Life
- 18 months when stored in unopened containers in a clean, dry area between 45°F and 90°F.
