Cracks in your stuccoed walls will mostly range from 1/16 to 1/8 inch wide. Don’t worry, these are pretty easy to repair; you can even do it yourself. You may also look for its cause to get rid of it. Here is a guide to help you.
For this project, you will need a caulking gun, caulk, bucket of water, and a sponge.
Open the tube of caulking by cutting its tip. Make sure that you make the hole as small as possible and at an angle, so the work is easier and cleaner. Then, load the gun and squeeze out some of the caulking to get an idea of how much is coming out.
Wet the crack and the area around it. Water will help with the application of the caulk and it will make it easier for you to clean up the excess. Then, you may apply a bead of the caulk evenly and generously. Follow the crack and use the angle on the tip to fill it. Be consistent and avoid gaps, so the fracture will seal completely.
Next, use your finger to spread the caulk into the crack. Make sure to go in different directions to fill it. To easily clean up, make sure you don’t spread it over to the wall.
Then, use your sponge and use water to clean up the area around the crack. Make sure that the caulking inside the crack will stay. Check if you miss any spots and that the crack is filled. Try to clean up as soon as possible to get a better result. There will still be a little amount of caulking around the crack. You have to get rid of it or you will see a slight difference in color.
Let the caulking dry. The drying time will depend on the weather, temperature, and the type of caulking that you are using, so be sure to check the instructions. It tends to shrink a little bit, but you will use it to your advantage.
The repair should match the texture of the stuccoed wall to look nicer. You may add the second bead of caulking at practice doing the texture on a scrap piece of wood or cardboard.
For smooth-textured walls, the method would be easy because you only need to keep reapplying the caulk until it blends naturally. For other textures, you might need to use a brush or sponge and do dabbing motions. Try to experiment which will best match your wall. You may even use a sandpaper for rougher ones.
You need to find a paint that matches your wall for the repair to blend in. Repainting the whole thing is also a choice, so it will look better. It is always up to you to decide.
Your stuccoed wall will relatively need low maintenance, but as it might be exposed to the weather outside, it is prone to damage. Make sure that you repair them at once to avoid larger problems.
