Waterproof Render
If we notice in our house that the plaster is brittle when we touch it, it means that it as been amaged by moisture and requires repair.
In the case of large areas of moisture damage, we may then hear a hollow sound when knocking and checking the hardness. In this case, it means that the plaster has been stripped off “that is, an empty zone was created between the plaster and the wall in which moisture collects”
If you observe the above-mentioned damage in your home, a water-resistant plaster with a properly matched mixture of sand and cement and appropriate hardening liquid is required.
We recommend to do new render for cover DPC from the external side of the wall,it is required when the bricks do not have render because they are damaged bymoisture.
