How to Repair Cracked Walls

Wall cracks are a common sight in most homes, and they don’t necessarily mean there is any structural problems. But they can be a nuisance, especially if the cracks appear near doors or windows. Most of the time, small hairline cracks in plaster and drywall walls are caused by natural settling and can be easily repaired with simple tools from your home improvement store. However, large gaping cracks can indicate serious foundation or structural problems and will require professional cracked wall repairs intervention.

Small hairline cracks can be cosmetically patched with filler and paint. This is because most of these types of cracks are simply a result of the contraction and expansion of the wall due to changes in humidity levels and temperature. Small gaps can also be caused by a number of issues, including water leaking into the wall’s framing, which can cause it to soften and deteriorate over time, resulting in a noticeable crack. It is important to address these issues as soon as you notice them to avoid further damage to the wall.

If you notice a crack in your wall, it is important to first clean the area and remove any debris that may have fallen into the crack. It is also important to ensure that the crack is completely dry before attempting any repairs, as damp walls will not allow joint compound to set properly. If the crack is caused by a water leak, you will need to find and repair the source of the leak as well.

For drywall cracks, it is best to apply two or three layers of joint compound, allowing each layer to dry completely between applications. After the last application, sand the area with medium-grit sandpaper to smooth it out and prepare it for painting. It is a good idea to wear a dust mask during this step to prevent inhaling the sand particles.

Plaster cracks can be repaired much in the same way, using a drywall patching product such as Selleys No More Gaps Coloured Caulk or Durabond. It is important to use the correct size of caulk, as larger or smaller patches will not hold up as well. To ensure that the patching product adheres to the surface of the wall, it is also a good idea to prime the wall before applying the product.

Cracks in brick walls can be more difficult to repair, and will probably require extensive masonry work. However, there is a method of repair called crack stitching, which involves embedding stainless steel helical bars into the mortar bed joints of the wall to prevent further movement and protect the integrity of the structure.
