Minor Crack Repair In Stucco

Many homes that have stucco as an exterior coating have cracking issues, but most of them can be repaired quite easily. There are different kind of cracks that appear and knowing how to go about fixing them is half the battle.

There are different kinds of cracks, distinguished mainly by their size and pattern on the wall itself. One can determine the cause of the crack by looking at the wall’s design, the size of the crack and the pattern.

These cracks are anywhere from 1/16 of an inch to 1/8 of an inch wide (typically) and are easily and effectively repaired using caulking and paint.

Materials Needed:

  • Caulking Gun

  • Caulk (latex with silicone base is recommended, 35 year)

  • Bucket of water

  • A sponge or rag

Step 1: Cut Tip Of Caulking:

The first step is to cut the tip of the tube of caulking as small as possible, at an angle, if possible. I included this as a step because it is oftentimes overlooked and can make a huge difference in the amount of time it takes to complete the project, how much cleanup there will be, the finished product,etc.

Helpful Tip: The smaller the tip, the easier and cleaner it will be to apply the caulking, the less cleanup you will have to do and the better the repair will look.

Then load the caulking gun with the tube and squeeze out some of the caulking, so your ready to go and have an idea of how much material is going to come out.

Step 2: Apply Caulk Spread Into The Crack

Next, you will want to apply a bead of caulk along the crack in an even and generous manner. Use the angle on the tip to your advantage, it will be easier to fill the crack this way.

Be sure to have a consistent bead without any gaps, you will want the entire crack to be covered in a bead so it is sealed entirely.

After the caulk is applied, take your finger and rub the caulk into the crack. Try to go all directions, in order to fill the crack entirely. Try to avoid spreading the caulk all over the wall, if you can do so, it will make the next step much easier.

Step 3: Wipe Off Excess Caulking

Now, take your sponge or rag and saturate it in the water. Ring it out a little bit, butkeep most of the water inside, it is better to have more water than not enough. Use the rag or sponge to clean up the area around the crack, while keeping the caulking inside of the crack itself.

Do not worry if you are shy on material here because we will end up applying a second coat that is textured and will fill in the rest of the material you need. Just make sure that the entire crack is filled and you didn’t miss any spots, this is critical in this step!

Helpful Tip: The final product should just have the caulking inside the crack and nowhere else. Try to clean around the edges as good as you can for a better end result.

Step 4: Let The Caulking Dry

Let it dry for a day, or a few hours, depending on the instructions , weather, temperature, etc. Caulking has a tendency to shrink up a bit, which will work to our advantage, in this case. We will apply another coat of caulking the same way we did in steps 1 through 3 but add a little texture this time around, to match the existing texture.

Step 5: Texturing The Second Bead Of Caulking:

After we apply the second bead of caulking and wipe
