A well lived in house will inevitable pick up a few scars here and there. Luckily, it is relatively easy to repair minor wall cracks. All it takes is a little stucco and some instruction. If you’re tired of hanging photographs or moving plants to hide cracks, here’s how you can fix them:
- Latex caulk
- Caulking gun
- Concrete bonding agent
- Whitewash brush (using scissors, cut bristles down to two inches)
- Small paintbrush
- Square trowel (margin trowel)
- Stucco patching compound
Once you have all of your supplies, it’s time to start the repair. If the crack is less than a quarter inch wide, fill it in with latex caulk using the trowel and cut off the excess caulk. While the caulk is still wet, apply some of the dry sand. The next day, brush off the excess sand. Ta-da! You have successfully repaired your wall.
If the crack is wider than a quarter inch, you’ll need to do a little more work, but the process is still simple enough for a careful beginner to do. In this case, you’ll need to prepare the cracks by brushing off the loose plaster with a trowel. Paint the crack with bonding agent so that the patching compound will adhere. Next, dampen the crack with water, and fill it in with fast setting stucco patching compound.
Make sure to mix the stucco patching compound fairly stiff. If you use too much water the compound will sag or even run down the wall. After the compound becomes dry to the touch, brush it with the whitewash brush until it blends with its surroundings. To cure the patch, you will need to lightly mist the patch with water. This will help with the curing process. If the area is deeper than an inch, you will need to use the same techniques, but only fill the area about half the depth, let it set for a day, then finish it just like the other repairs.
Sometimes the hardest part of patching a crack is to match the texture and color of the wall so that the patch job is not apparent. You can solve this issue by bringing paint chips from the wall to the paint department of the hardware store and buying a matching stucco paint color.
Not so bad right? Most small and minor cracks can be repaired by the homeowners. Larger areas of damage, however, may require the skills of a stucco repair expert. If you are unsure of how to continue, give my crew a call. We can send somebody out for a free repair assessment.
