Stucco refers to the hard-wearing siding material that resembles cement. It may be durable and probably last a century. However, repairing stucco may be necessary for possible cracking and holes. Large fissures and blisters will lessen the cladding material’s endurance. This results in rapid decay. The repair work is not that hard. Yet, proceed cautiously to ensure the stucco lasts longer that you expect.
It seems logical to let the mason work on major fixes. Nonetheless, you can take care of minor repairs with a bit of DIY experience. The task entails dealing with tiny cavities and gaps. The job depends on the hole’s size as well as extent of damage. You may use acrylic latex painter’s caulk or seal for thin crevices. The caulk’s color must look like the stucco tint.
For bigger cracks (one-fourth inch and more), fill in the fissure using pre-mixed stucco patch and small putty knife. Let the siding set according to the manufacturer’s recommended time. You may apply several layers to seal the crack adequately. Make the blotch flush by enclosing the surface. For small gaps, touch up the sealed area with matching paint.
Fixing the Big Holes
As mentioned earlier, plugging the huge hollows can be left to skilled craftsmen. However, smart homeowners with fundamental knowledge in household repairs can handle this chore efficiently. Here’s the problem. It becomes harder to make a patch that balances well with your walls. Your only option is repainting. In this case, you’re better off employing a capable siding contractor.
For the Do-it-Yourself Homeowner
In case you still prefer the DIY approach, follow these steps:
Break the stucco lose. Use the chisel with a cutting-edge blade and hammer (ballpeen type) in removing the siding from the surface. Make sure you don’t damage the main floorboard support. Use googles as eye protection from flying fragments.
Continue with the process until you reach the stucco firmly connected to its lath. Take away and cut the metal mesh using heavy-duty shears. Staple new wire lattice over the damaged wire. Spray with cold water.
Apply the initial stucco coat within ¼ inch of the exterior. Use the putty tool or trowel. See to it stucco seeps from the back of the mesh. Scratch using any pointed metal object (preferably a nail) once it is firm. Allow to cure for at least two days.
Cover the wood that serves as foundation for the wall. Use your utility knife to clip the piece of builder’s paper after chipping the stucco. This paper is necessary in painting and construction as protection for flooring. Building paper prevents water from leaking to the substrate or layer as well as structural support elements.
Fasten the paper to the lath. Use roofing nails. Then, fix the second layer of paper on top. It must fit securely along the edge where the stucco touches the wooden foundation.
Spread the second coating over the moist first coat. It should be within one-eight inch near the surface. Flatten the cladding and allow curing for 48 hours.
Apply the last coat. Again, see to it the second coat is damp. Use the trowel or metal float. Flush the surface smoothly or until you achieve the desired texture. Allot four days for curing.
Paint the surface if needed.
For deep chasms, increase the patch using consecutive layers. Let each one dry thoroughly before putting on the next. Match the grain by touching up with a small brush.
Fixing Smaller Holes
In repairing stucco, the smaller hole measures less than six inches in width.
Start by cleaning the hole using a stiff brush. Use an awl or small piercing tool for scraping tiny holes. The nail set (hammer) is another option. Blow away the dust.
Smear a new blotch of the patching compound. Place it tightly inside the hole. Fill up near the surface. Allow the patch to become solid.
Apply the top coating of patch. Use your putty tool in blending the surface until it matches the walls. Let the coat dry totally.
Repair Stucco Ruptures
Stucco flaws have turned up as a common issue for most homeowners. The siding starts to break over time or due earthquakes and strong winds. A correct method of repairing stucco is subject to the size.
For very thin cracks, apply a coat of acrylic latex paint. The color must match the siding. Opt for the caulking compound if the gap becomes too broad for paint to pack the openings. Allow enough time for drying before painting the top with acrylic paint.
For broader crannies, spread the all-purpose filling substance like the pre-mixed patch designed for stucco fixes.
Dealing with Stained Stucco
Even if the stucco surface is resilient, it can look worn-out sooner or later. You cannot use the standard house paint compared to other cladding materials. Keep in mind the walls need to take in air. If not, the inner moisture tends to accumulate beneath the paint which causes peeling or blistering.
Ask a stucco contractor to dash off the walls. A simple but not permanent remedy would be whitewashing your walls. However, the walls must have been painted with white color. Mix cement and water. This process must be performed by a professional service provider.
The Final Coating
How should your final coat of stucco look like? The last layer is fine colored cement (stucco) that refers to the final texture and shade. To apply this finishing layer, use the trowel for ½ inch or smaller in terms of thickness. See to it the stucco settles firmly in the tracks. You can create designs while the last coating is still wet.
Allow the patch to cure for seven days before painting everything. The patch will look invisible under an overlay of acrylic elastomer. It refers to synthetic rubber with heat and oil-resistant properties. At this point, you have just completed your stucco repair project.
