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.
Repairing Hairline Cracks:
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)
- There are also tubes that do not require a caulking gun (shown below)
- Bucket of water
- Sponge or Rag
1) The first step is to cut the tip of the tube of caulking as small as possible, at an angle, if possible. The smaller the tip, the easier and cleaner it will be to apply the caulking. Then load the caulking gun with the tube.
2) 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.
3) 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.
4) Now, take your sponge or rag and saturate it in the water. Ring it out a little bit, but keep 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.
5) Let it dry for a day, or a few hours, depending on the instructions , weather, temperature, etc. Reapply a second coat if needed.
6) Then paint the crack with a fine tip brush. It is better to paint the entire wall or house for a better color match.
