- For optimal adhesion, create a roughened or “V” shape profile at the leak
- Porous substrates should be pre-soaked before applying

Due to the rapid curing of Sika Plug, mix only small amounts at a time:
- Quickly combine powder and water in a container
- Mix thoroughly and apply immediately with a gloved hand or trowel
Application Process
- Firmly press the mixed mortar into the leaking area
- Hold in place until it hardens
