How to repair Water Proof Masonry Wall Cracks easilyDIY Guides

Water or heavy rainstorm or snow can cause your Masonry wall to crack easily if it is not maintained properly. To identify water penetration, make sure that after heavy downpour there are no dark patches on the wall meaning that the water has soaked into the wall\’s surface. This is also known as leaching water that later on will become moisture which will slowly find its way through the masonry wall and produce cracks. Below are some of the steps required for repairing water proof Masonry wall cracks.

What you need:

Cement
Cold Chisel
Light Brush
Epoxy or Latex
Garden Hose
Pointing Trowel
Work Gloves
Hand Cleaner
Spray Nozzle
Star Drill
Wire Brush
Waterproofing Mix
Chipping Chisel
Hammer
Stiff Brush
Weep Pipe

Method:

First of all, you need to find the exact location of the water proofing cracks on the building or on the wall. For a hairline cracks, you can just fill in the cracks with a regular waterproofing mix, while a large crack like more than 1/8-inch need to be cleaned out and patched before applying any waterproof mix.
You can also use special epoxy and latex cement formulas for repairing large cracks or mixing your very own mortar for patching holes and cracks before applying any waterproofing coat. The mortar consists of one part cement and two parts fine sand and a little bit of water.
Besides that, a weep pipe can also be used through the wall for permitting outside water trapped against the wall to escape. Insert the weep pipe where the pressure is greatest. Use also an ordinary pointing towel. Completely fill the crack with mortar especially at the location where the weep pipe is installed.
When applying the waterproofing mix, the surface should be completely dry. Always remember that no epoxy or latex waterproof coatings can be applied to wet surfaces.
You can use a stiff brush and rub the waterproof mix onto the wall in a circular motion rub by using a stiff brush. In order to make the coating does not rub off easily, spray the area with water, soak it thoroughly and let it dry overnight.
After that, wet it thoroughly using garden hose and apply a second coat of waterproofing mixture while the wall is still wet. The same techniques for brushing need to be applied on using the second coat as you did for the first coat.
