Fast-setting hydraulic cement mortar
SpecPlug is an amazing fast-setting hydraulic cement mortar. It's designed to quickly stop water flowing through holes and cracks in concrete and masonry. When it sets, it expands without shrinking or oxidizing, giving you a long - lasting repair.
- It's a single - component product. Just add water and it's easy to use.
- It expands to form a strong, watertight bond with the substrate.
- It sets in about 3 - 5 minutes, rapidly halting flowing water.
- It can be used for both vertical and underwater applications.
- It's certified to NSF/ANSI Standard 61, so it's safe to contact with potable water.
Application
SpecPlug is great 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 the best results, make the crack at least 3/4" wide and deep, and shape it square or undercut.
- Cleaning: Remove all grease, wax, oil, contaminants, curing compounds, and any weak or deteriorated concrete from the surface.
- Wetting Surface: Soak the repair area with water. SpecPlug can cure even with running water, perfect for active leaks.
Mixing and Application
- Mixing SpecPlug:
- Add a little clean water to SpecPlug to get a putty - like consistency. The water - to - product ratio by weight should be 20% - 21%.
- Only mix as much material as you can use within 2 minutes.
- Application Procedure:
- For vertical and moving - water applications, hold the mixed SpecPlug firmly in place until it sets, usually in about 3 minutes.
- Adjust the water temperature to control 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 help it cure. You'll get the best strength by wet - curing it for up to 2 days.
Using SpecPlug is straightforward. First, prepare the surface. Make sure to enlarge cracks to at least 3/4" in width and depth, clean off any grease, wax, oil, and weak concrete, and soak the repair area with water. When mixing, add a small amount of clean water to get a putty - like consistency with a 20% - 21% water - to - product ratio by weight. Only mix as much as you can use in 2 minutes. For vertical or moving - water applications, hold the mixed SpecPlug firmly until it sets in about 3 minutes. You can adjust the setting time by changing the water temperature. After application, keep it damp for at least 30 minutes, and for the best strength, wet - cure it for up to 2 days. Remember, SpecPlug is certified for safe contact with potable water and can be used in various places like basements, manholes, and swimming pools.
