Concrete Stucco

Patch a concrete wall with stucco?

We buy a house "as is" and there is a hole in the wall outside. When the new plumbers-plumbing the house, they demolished some of the walls to expose the pipes, but never repaired the hole. The pipes actually run through the cement blocks, to make new block is almost impossible. The hole is about. 2 feet wide at the widest part and 3 meters high at most. Does someone knows how to patch this kind of hole?

It would be almost impossible to repair with new block so as best you can do is fill the void. Remember to leave some room around the plumbing so that the wall can dilate and contract, moving ADND should there be an earthquake earth. The easiest way to repair would be to wrap the pipes as good as you can with a soft material that you can remove or leave in place. I propose a newspaper or wrapping paper in cellofane. Be the common 1 / 2 "-5 / 8" thick to allow it to move, you can also use a strip of bentonite waterproof who seal the joint. Call a roofer or contractor impervious to locate. Depending on the access easier to install 1 / 2 "plywood cons on the opening using a jigsaw to cut for pipes and soft matter. Make sure it is tight and secure, and you may want to tape the edges to contain the concrete. Plywood must be rigid so as not to bow out with concrete installed. Use reinforcements if necessary. Do the same thing on the side you Leave empty and a gap of about 3 "at the top of the hole to allow the concrete to be poured. Mix Concrete loan a coward, but not really wet consistency. (Batter) and pour it into the hole. Use a stick or a piece of dowel rebar Wrapping and consolidate the concrete after you pay. As you get near the top of the hole, mix in the mix more concrete to stiffen the lot and hand pach upper hole to ensure that compensation is full depth and height. Before the concrete is too hard (test with the party open) delete the form of plywood so that you can cut or scrape off the high points or mud that has passed while the form is still a little soft. (Check after 2 hours) to clean the area near the hole with a damp sponge and a stiff brush to remove stains and suspension. After that the material is hardened likley you need to fill small holes and cracks. You can do this with the same concrete mix if you use a sponge float or a stiff brush to work it in the patch. It will be a slurry and provide a uniform finish on the concrete surface. If the stucco is textured you will probably want to sift gravel and just use the sand to apply as a condition. You can too, but a bag of plaster and apply a top finish stucco with a trowel. Make sure wet the patch with water before placing the stucco or suspension to slow healing. Also be sure to maintain the expansion joint in the pipes. Caulk them when you're done with a good 100% silicone or polyurethane sealant to keep water out. Finally I suggest that you pack the center 4-5 "of wall with newspaper or cardboard in bulk for use as filler, then patch the concrete on both sides as requested above. Thus I approach the repair. Good luck with it. It should be realtively easy to do.
