How-To Repair Exterior Cinderblock Walls with Stucco

Since the early 19th century Stucco has been used to encompass less appealing structure materials such as physical, metal and cinder block.  Designed for exterior utilise, it wasn't until tardily 19th century that builders started to utilise it on interior applications likewise.

Old decaying walls tin actually be an eye sore. By and large they become the focal point of your yard, even if you take the nicest property in your neighborhood. It is similar driving by an accident on the highway, yous know you lot don't want to stare, just nosotros always do!

Recently I had a client who had some serious issues with some patio walls in their backyard. They love to entertain but shied away from barbeques and parties due to a couple ugly cinderblock walls. With their son's birthday coming upwards they decided to stucco over the walls to make them more appealing.

Step 1 – Prep

The first pace in stuccoing walls is to prep them correctly. Y'all need to brand certain y'all remove whatever aging blocks and loose debris. Chip abroad and piece that may stick out farther so others to ensure y'all take a nice flat service. Clean off the walls with a brush removing all the grit and dirt. In cases like mine the walls had some pieces of block that were completely missing due to poor drainage. Fill them in with some mortar and let it dry out. You desire to make sure you are as close to level / apartment every bit possible before you commencement applying the Stucco.

When applying new stucco to an existing concrete you need to apply a bonding agent. In our example we used Quikrete Bonding Agent that we picked upwards at the local Home Depot. Instead of roughing up the pre-existing concrete, you lot simply ringlet or brush on the agent. The directions indicated to employ new stucco within three hours of applying.

Step 2 – Mixing Stucco

Now that your walls are prepped and bonding amanuensis is drying, you need to get-go mixing your stucco. Stucco is fabricated of four major components: Portland Cement, sand, lime and water. The mixing ratio may vary depending on who you ask. For our walls we used 3 parts sand, one role lime and one part Portland cement. We add water until it is the consistency of brick mortar.

You lot want to be intendance when mixing mortar as it can dry out quickly. My rule of thumb is merely mix virtually 90 minutes worth. Annihilation more than than that dries out also quickly and yous are constantly adding more than materials to it to become it back to workable consistency. Another thing to consider is the temperature. Hot and humid days will speed up the drying process and typically slows down your work speed. On hot humid days, I typically will simply mix minor a corporeality at a time.

Step 3 – Applying the Stucco

First Glaze

Typically I similar to apply ii coats of stucco on the walls I am covering. Starting time coat is my filler or skim coat and the second coat is my finished coat. Work your stucco over the large cracks and gaps start filling them in before you first applying the stucco to the whole wall. If you just start applying information technology and ignoring the large gaps or cracks yous are going to have an issue when you trowel over them. The stucco will not stick well. Then I recommend hitting those showtime.

Once you lot take your offset coat applied, have a Stucco Float and knock down the rough edges. Information technology doesn't have to be perfect. Salvage that for your finished coat. Be certain to make clean up your work area one time your first coat is complete. Stuccoing is a messy chore, exist certain to clean up while the stucco is nonetheless moisture, information technology volition avert a lot of scraping later.

Finished Coat

Afterward the stucco is dry, y'all are ready to apply your finishing coat. With this coat, you desire to pay attending to making it as smooth as possible. I observe working from the bottom upward works best for me.

Once I get the stucco applied, I allow it to fix just a bit earlier I utilize my sponge float to smooth it out. With the sponge float, utilise plenty of water, smoothen out the stucco making sure you pay close attention to your seems if yous accept any. The seems are going to prove if you do non plumage them properly. Just like mud and tape on drywall, your seams are critical and usually the first place that fails.

DIY or Not?

Is Stucco easy enough for the DIY'er to tackle? Absolutely! In that location is little you demand to know when stuccoing. Make sure you take the correct materials and the correct tools and you should be all set. Also, can you make the wall any uglier than information technology already is, correct?!?!

Stucco tin be washed in a weekend, or if you are actually good, you lot tin can nail it in a day. Take your time, make certain your mix is perfect, your seams are smoothen and your expanse is kept clean and you will be a Stucco pro earlier you lot know information technology!
