DIY Stucco Ceiling Repair: Simple Steps to Get it Done Right

Repairing a cracked stucco ceiling requires a few simple tools and supplies. If the crack is thin, cement caulking may be used to patch the crack, however, if the crack is larger than one inch, a special stucco mix must be used. Taking the necessary safety precautions before you start, such as putting on goggles and gloves, and wearing a dust mask and clothes you don’t care about, should be your first step.

The first thing needed when repairing a cracked stucco ceiling is a set of hand tools. At minimum, you will need a chisel, an air hose, a trowel, a sponge and a brush. Depending on the size of the crack, you may need to use an old vacuum cleaner to suck out debris from the crack. Next, you need the necessary materials to make the repairs. For thin cracks, you will need a tube of cement caulking or a pre-mixed stucco mix for larger cracks. If you choose to use stucco mix, you will also need a bucket, water and some mixing tools.

The first step in repairing the stucco ceiling is to find the source of the crack. There can be several causes, such as a foundation shift, water damage or floor joists splitting. If the crack is very wide and runs the length of the ceiling from the center out, or from the corner in, you could have a serious additional problem, so you should consult a contractor or home inspector for an evaluation. If the crack is minor, or very thin, you can take care of it yourself.

Once the crack is found, carefully clean out the track. This can be done by using a chisel to dislodge any pieces of stucco and by using the air hose to blow out the crack to ensure no dirt or debris is left in the crack. Remove any weak parts of stucco as well. To start the repair process, spray the crack with water. If you are using a stucco mix, mix up enough to fill the crack and use the trowel to smooth it out and add texture. Smooth it out as best as you can.

If the crack is thin and short, then you can use a tube of cement caulking to patch it up. Use your finger or the brush to press it into the crack, making sure it enters throughout the entire length of the crack. Once the caulking is applied, wipe off any excess with the sponge. Allow it to dry.

After the crack is repaired, you can paint the ceiling with a matching color. You may have to repaint the entire ceiling as the newly patched stucco may have a different texture compared to the rest of the ceiling. By taking the time to fill a stucco ceiling crack, you will be able to protect your ceiling from further damage and extend the life of your stucco ceiling.
