There are reasons why most houses sport cement walls on the exterior. First off, it is sturdier than wood based walls. Secondly, it provides maximum insulation against the outside elements thus, protecting the occupants from it. Thirdly, it provides a fire-free insulated barrier. However, through natural wear and tear, this once sturdy cement wall of yours will soon falter due to many factors such as the pressure of the interior and exterior temperature, the shifting of the ground beneath it, and, of course, other natural factors such as earthquakes and typhoons. The damage on a cement wall will start in the form of small cracks. If these cracks are not repaired and tended to immediately, it will spread like a virus and soon enough, it will be the cause of the wall tumbling down one day in the future. Hence, it is important to repair any signs of cracking as soon as you see them. Here are some steps to keep your wall sturdy and resilient.
- Inspect your walls. This should be done from time to time as cracks can appear out of nowhere, sometimes in the most unexpected of places. However, most cracks start at the bottom so, make sure to pay attention to that area of the wall when inspecting it.
- Enact the repairs. In order to repair a wall with mild to severe cracks, you will need cement. This is the only way to fill in these gaps and allow both sides of the crack to bond. Mix the cement as instructed on the packaging. Make sure to keep it moist until you are ready to apply it.
- Before applying the cement filler, you will need to prep the wall, particularly the area of the crack. If the crack is too fine, you will need to widen it a bit so that you can insert the filling right at the center. This will involve some chisel work. Make sure to clean up the mess after and brush off any remaining debris.
- To apply the cement, use a putty knife and make sure to get the cement filler deep inside the crack, as deep as it can go. Use the knife to level the filler with the rest of the wall once the crack is filled and packed.
- You will need to dry out the cement in order for it to create the bond. You can temper and help the process by covering the newly patched crack with plastic cardboard. This will enable the filler to dry on the inside going out. However, remember that the longer the filler dries, the stronger the bond will be.
- Now, if the problems on the wall are minor gaps, those that won’t really affect the integrity but can affect the aesthetics of the wall, simply fill it in with either cement filler or some Spackle.
Whatever is the case, some sanding of the repair may be required to
match the filler with the rest of the wall. Once you are done with the
repairs, you can repaint the area of the wall to match the color of the
rest of the wall.
