Plug holes in walls—even walls with active leaks—and then paint over the patch

Leak Stopper is a very fast setting cement-based product that is designed to stop the flow of water through small holes or large cracks in concrete walls or masonry units.

Since leak stopper sets so quickly it is best to only mix small amounts by hand.

 

Application:

  • Add one part of water to the mixing container first, then add three parts leak stopper, mix using a small trough for about a minute.
  • The mix will be very fluid initially but will stiffen rapidly, then scoop up the mix in your gloved hands and work it back and forth from one hand to the other until it begins to stiffen.
  • In this application, Leak Stopper is being used to plug a hole with an active water leak. Once the mixture has begun to stiffen, force a larger amount of Leak Stopper into the hole, you want to overfill the hole and the surrounding area.
  • Allow the mix to harden for another minute or two and then using the trough, scrape off all excess material. By using a trough and then a wet rag you can remove all excess material, leaving the patch flush with the surface. When the wall dries, it can be painted. 

 

Tools needed:

  • Mixing container
  • Measuring container
  • Gloves
  • Finishing or margin trowel
