Many homes that have stucco as an exterior coating have cracking issues, but most of them can be repaired quite easily. There are different kinds of cracks that appear and knowing how to go about fixing them is half the battle.
Cracks can be 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 be effectively repaired temporarily using caulking and paint ( this method lasts about 5 years ). Cracks larger than 1/8″ should be professionally repaired by a qualified stucco contractor to prevent future cracks or to extend the life of the stucco system.
What You Will Need:
- Caulking Gun
- Caulk (latex with silicone base is recommended, 40 year) or a sanded caulk, for rougher stucco textures
- There are also tubes that do not require a caulking gun but have much less material in them than a standard tube of caulking
- Bucket of water
- Sponge or Rag
Cut Tip Of Caulking Tube, Like This:
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.
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.
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.
Wet The Wall Down Before You Do Anything…
First, you will want to wet down the wall where the crack is and around the area of the crack. Water will help move the caulk around, make it squeeze into the crack and will allow you to wipe off the excess a lot easier.
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…
After you apply the caulking, it will look something like this (above photo). This is where cutting the tip of the caulking tube carefully comes in handy, the smaller the crack, the smaller the opening on the tip of the caulking tube should be. This will keep things neat and make the job come out a lot better in the end.
Spread The Caulking Into The Crack Using Your Finger:
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
