You will need a putty knife, sandpaper, exterior wall patching compound, a paintbrush, and exterior paint. Depending on the size of the damage, you might also need a trowel or a caulking gun for larger holes.Assess the DamageTake a close look at the area that needs repair. If you find small cracks, you can easily fill them with caulk or patching compound. For larger holes, you may need to use a patch or mesh tape in addition to the compound. Remember, proper assessment is crucial to ensuring the right repair method.Clean the AreaOnce you've assessed the damage, clean the area thoroughly. Remove any loose debris, dirt, or old paint that could prevent the patching compound from adhering properly. A clean surface is essential for effective repairs.Apply the Patching CompoundUsing your putty knife or trowel, apply the patching compound over the damaged area. Smooth it out evenly and feather the edges to blend it with the surrounding wall. Allow it to dry as per the manufacturer's instructions, typically around 24 hours.Sand and PaintAfter the patching compound has dried, sand the area gently to create a smooth finish. Once satisfied with the texture, clean off any dust and apply exterior paint that matches your wall. This will help conceal the repair and protect it from the elements.What’s Your Next Project?Patching your exterior wall can feel rewarding, but it’s just one of many home improvement tasks.
