Rust-Oleum Leak Seal seals around wood windows and doors

Cracks around wooden window and door frames are common enough and these need to be attended to as soon as possible if you want to prevent further problems.


I have a long, thin crack that runs along the bottom edge of my sliding door. When you consider that the sliding door is wood, expansion and contraction occurs regularly ant it's almost impossible to prevent cracks here.

To repair this area I'm going to use
Rust-Oleum Leak Seal, which is a rubberised spray that seals cracks and fill small holes with a flexible finish.





The reason I'm using Rust-Oleum Leak Seal on this area is so that the cracks is filled/covered with a flexible material that will allow some expansion and contraction of the wood frame.

To prevent any overspray I placed masking tape above and below the area to be sprayed. Shake the can well and then shake again to be sure. Hold the can at least 30cm away from the surface and apply a light even stroke from one side to the other. Let each coat dry before applying the next coat until the area is filled or covered nicely.

You can repair and prevent leaks on a wide range of surfaces with this rubberized coating:

Great for gutters, roofs, flashing, ductwork, PVC, masonry, concrete and more

  • Seals leaks and cracks water-tight
  • Paintable finish

Rust-Oleum Leak Seal provides firm-but-flexible protection against moisture and rust on surfaces that need it most. Find the wide range of Rust-Oleum products at your local Builders Warehouse.
