Steps to repair cracks and holes in internal walls

What causes a wall crack?

Visible wall cracks are one of the most common concerns individuals have with their home’s structural integrity. Concerned that these wall cracks cause further breakdown of the wall or allow water to penetrate further, it’s important to under what causes a wall crack. Here are some of the main reasons why a wall develops a crack:-

1. Settling over time 

Just like our skin develops wrinkles and fine lines as we age, so does your home. As your home ages, it undergoes several changes, movement of the ground, and expected wear & tear. This may cause tiny wall cracks based on what changes the house undergoes.

2. Vacant home  

Leaving a home vacant can also cause wall cracks! The lack of climate control and other solutions like waterproofing and dampproofing can cause the development of wall cracks on interior and exterior walls.

3. Faulty drywall taping

As your home has drywall, it is essential that they are correctly taped or else it can cause wall cracks. Drywall panels are joined at the seam by drywall mud, and the seam is then covered with tape and finally painted. If this seam isn’t properly filled and sealed, the tape can start to disintegrate and leave thin cracks in your wall.

4. Water leak

One of the most common issues in households is water leakage and eventual damage. Water finds a way to get through and thus, waterproofing is essential. Moisture can also ruin drywalls by softening it and ultimately causing cracks.

Why is wall crack repair important?

How to Repair Your Wall Crack?

1. Clean and Prepare the Crack

Clear away furniture and other home decor items and put down a sheet below the wall with cracks. Using the right tools and equipment, gently open up the cracks to ensure that the wall crack filler or crack filler for concrete can be effortlessly applied and is the best solution for securing concrete cracks. Dust away fallout material and spray water to prepare for crack filling.

2. Apply Crack Filler or Patch Compound

Using the right tools or knife, apply the wall crack filler or patch compound into the holes and push it in. Spread it evenly & smooth off the edges in a feathering motion for a professional touch, this will help to cover all the cracks uniformly. 

3. Adding Layers for Larger Holes

If your walls have larger holes, they will need special care. Ease open the hole, dust out all loose material, and spray some water to prep. Apply the crack filler for walls inside the large gap, and spread it in a criss-cross pattern for better grip of the next layer. Push it in evenly and wait for it to dry before you add more layers to fill the large hole or deep crack. Once it’s filled to the edge, even off the last layer for a smooth finish! If the crack filler is not appropriately applied for large holes in your walls, it is best to seek professional assistance for the best crack filling service! 

4. Reinforce with Mesh Tape

For wider or deeper cracks, reinforcing the area with mesh tape can provide added strength and prevent future cracking. After applying the initial layer of crack filler or patch compound, place the self-adhesive mesh tape over the crack. This tape helps to bridge the gap and stabilizes the repair. Once the tape is securely in place, apply another layer of the patch compound over the tape, ensuring it's fully covered. Smooth the surface evenly, feathering the edges, and allow it to dry completely before sanding or applying additional coats if necessary for a seamless finish.

5. Smoothening Corners

For cracks and holes on corners, fix this using a straight batten or a long, flat piece of timber. Nail the batten or timber with one edge of the corner, fill the crack until it is sealed completely, and smoothen the surface with the batten.

6. Sand, Prime, and Paint

For a superior finish, lightly sand the areas where you applied the crack filler or crack seal for walls with fine sandpaper once the filling is completely dry. Apply a coat of wall paint or wallpaper for the finished look!
