How to apply a water leak sealant

  1. Locate leak

    First find out where the water is making its water into the material that is causing it to leak.

  2. Clean surface

    To get a good quality seal, clean the area thoroughly before applying the sealant.

  3. Apply sealant

    Apply the sealant at the leak location. Filling in the gap or hole as much as possible will provide a better seal than just covering it over the top.

    If there is any excess sealant, remove it before it cures.

Please note that Adiseal sealant is not suitable where the leak on pipe is pressurised, like in mains water pressure.
