Walls waterproofing

Although vapor barriers are meant to prevent moisture from entering your home, they can also retain water on their exterior layer. This will create a layer of moisture under the floor. The moisture can be penetrate through small holes and enter your home.

There are two main solutions for solving this problem: one is to install a different product to create a double protection, and one to install insulation.

Some of the tools and materials that you will need are:

  • Vapor Barrier Paint
  • General Paint
  • Paintbrush
  • Timber
  • Nails
  • Hammer
  • Vapor Barrier Sheets
  • Insulation


One solution for avoiding moisture in your home is to apply a layer of paint and not install plastic sheets. Paint is much more effective for stopping moisture than plastic sheets. You can use a brush  to apply the paint. Make sure you cover every inch. Avoid creating air bubbles.

Second coat

After applying the moisture resistant paint, you should apply a normal paint over it, to better protect it. Let both of the paint coats to dry.

Timber frame

If you have plastic sheets as a vapor barrier, and you still have infiltration problems, then you should think of lifting the sheets up off the floor. You can do this by using timber over the concrete floor. The barrier will be installed over the timber frame. Create box frame using the timber to create a special foundation for the plastic sheets.

Floor insulation

Another thing that you can do to stop moisture from infiltrating your home is use insulating foam. Cover the base of the walls using a waterproof material and then use the insulating foam to create a layer between this material and the dry wall.
