Investments are essential to us, and one of the most major ones is probably your house. Naturally, you want to keep it presentable. One of the choices you may do is applying stucco finish to your exterior walls. That is a great option because of the numerous advantages you may get. It is fireproof, durable, and low maintenance. However, you will still need to repair it if ever it gets damaged.
One of the common damages your stucco may have are holes. If you do not take care of them at once, you may find yourself having a larger problem. These holes may be easily taken advantage of by moisture or fungi that can make it blister or have efflorescence. Make sure to take care of problems right away to prevent bigger ones.
The process for repairing holes is quite simple, especially if they are small ones. However, it will get more complicated if the damage is larger. You will need more materials and tools to do it.
You will need metal snips, protective equipment, new metal lath, stucco mix, trowel, float, and double D building paper.
First, you should prepare yourself and wear proper protective equipment and work clothes. You may also prepare the area around you by masking them off with painters tape and cloth to avoid getting cement all over the place. Make sure that your materials and tools are ready and handy.
Get your wire brush and get rid of dirt, debris, peeling paint, and loose stucco from the damage. Make sure that you are gentle and careful, so you won’t damage the ones that are still attached to the wall. Cut out the metal lath from the damaged area using your metal snips.
Cover the exposed area with two layers of double D building paper. Cut a suitable size that will fit in it and staple the first layer before adding the second one. Doing that is essential to create a moisture barrier and protect the wood behind.
Cut a piece of metal lath to replace the old one that you just removed. Place it in a way that it will overlap with the other metal lath. Secure it with roofing nails and make sure it will penetrate the wood by at least an inch.
Prepare your stucco mix. You may get one that is already pre-made. You can get them in local hardware stores in your area. You may also make your own, but make sure you correctly get the proportions for sand, cement, and lime. Add enough water, so it is workable, but not saggy. Keep it somewhere shaded. It will have a working time of 45 hours, so make sure you only mix what you need at a time.
Wet the area with some water and trowel the first layer of stucco. Make sure that it adheres to the old stucco properly. Scratch the surface and let it cure properly.
Then, apply the brown coat like how you did the first one. Make sure that it is uniform in thickness.
Apply the final coat and let it cure properly.
Maintain your stucco even if it may not need too much effort. That way, it will keep your house pretty for months to come.
