Now, take your sponge, rag or green float and saturate it in the water.

Ring it out a footling bit, but keep most of the h2o inside, information technology is better to take more water than not plenty.

Utilise the rag or sponge to clean up the area around the crack, while keeping the caulking inside of the crack itself.

Do non worry if you are shy on material hither considering we will terminate up applying a 2d coat that is textured and will fill in the rest of the material you need.

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 aforementioned way we did previously merely add a niggling texture this time around, to friction match the existing texture.

The second glaze of caulking is optional and is normally not carried out by most people, as it takes more time, energy and resources. Sometimes i application of caulking is enough to fix the crack.

Texturing The Second Bead Of Caulking (Optional):

After nosotros use the 2nd dewdrop of caulking and wipe off the excess, we volition want to add a scrap of texture to make the repair blend in a trivial better.

Earlier you try to texture to the wall, play with it on a piece of paper-thin to try and simulate the texture and detect out what methods (dabbing with a brush, using a sponge, etc.) will match the existing texture the best.

If you take a smooth texture, and so this volition be easier to do and will only require (in most cases) to proceed reapplying caulking until it is flush with the finish and make sure at that place are no "hard lines" in the caulking, everything should alloy in naturally.
For moderately heavy to heavier textures, a brush used in a dabbing motion would friction match the existing texture better.
Experiment start, similar I mentioned earlier to see what method works the best for your texture. A sanded caulk would piece of work better for rougher stucco textures and be easier to attain a more than seamless repair.

Step half dozen: Apply Color To The Repair (Optional):

For the repair to be consummate, you will demand to employ a matching colour glaze on top of the area you fixed and possibly the entire wall, so it blends in better.

Virtually folks just pigment the wall and is probably the easiest method and well-nigh cost constructive i.

If you want to avert painting, then look into a fog glaze (traditional cement based stop) or an acrylic terminate that was used on your home (custom color matched) that has the aggregate taken out of information technology.

Y'all can achieve this by running the cloth through a mesh paint screen, which will proceed the color in tact but remove the aggregate to make a custom acrylic paint.

Helpful Tip: Information technology is hard to friction match the color of stucco exactly.

Information technology is porous and the color matching programs that are used these days volition pick up on the "shadowing effects" that the uneven surface of the finish has.

Keep this in heed if you are planning on painting and need to have your stucco color matched.
