The trend of people choosing to go with Stucco for their homes is steadily rising and it’s easy to see why. Stucco is a blend of Portland cement, lime, sand and water and provides a number of benefits such as being durable, low maintenance, and having a classic look. On the other hand, stucco can also be difficult to clean and getting this wrong could mean permanent damage. That’s why it’s important to learn exactly how to clean stucco and ensure that you’re doing it correctly.



How to correctly clean stucco?

This guide should help you understand exactly what you need to do to clean your stucco surfaces.

Inspect the Surface for cracks or anything that could cause damage inside the wall

The first thing to do is take a look at the surface to check for any cracks or anything else that could cause damage if water were to get inside. If there isn’t any damage or cracks then you can move on to the third step. However, if there is damage then it’s imperative to fix it first.

Repair Surface and Seal Cracks

Once you’ve inspected the surface and repaired any cracks, the next step is to seal any cracks you find and ensure that the surface is fit for washing. An exterior acrylic caulk will do the job for most minor cracks and damage but for bigger jobs it’s best to hire a professional painting company. 

Spray Stucco

Once you are sure there isn’t any damage, you can begin the cleaning process. You can rinse it down manually or by using a pressure washer on a low pressure setting. You want to avoid using a high pressure setting as this could cause damage.

Apply Cleaners

The cleaner you use will vary depending on how dirty the stucco is. For general cleaning, you can use a solution of water and mild detergent will be fine. However, if there’s mildew, you may want to use bleach and possibly a concentrated stucco cleaner.

Once the cleaner is applied, you should let it sit for 5-10 minutes but don’t allow it to dry or else you’ll struggle to get it off later.

Scrub or pressure wash

Next you can scrub the surface clean with either a soft bristle brush or a gentle setting of a power washer. When using a power washer, it’s important to be very careful not to damage the stucco by either using too much pressure or improper technique. If you’re unsure about this, then stick with a brush or hire a professional team to do the pressure washing.

Final Rinse

Finally, you’ll want to give the stucco a final rinse with clean water to remove any soap residue and ensure that it’s completely clean. And there you have it, a simple guide on how to clean stucco without damaging it.

How often to clean your stucco?

We typically recommend that you clean your stucco once a year. However, this is a general rule and you may want to do spot cleaning more frequently if necessary.

Tips to Keep Stucco Clean Longer

If you’re looking to keep your stucco cleaner for longer, then a great trick is just to use your hose. Every now and then, it’s a good idea to hose your stucco down and this will help to remove any dirt or debris that’s sitting on the surface. You’ll be amazed to see how much longer it will keep your stucco clean.

Best Stucco Cleaner to use

As we mentioned before, different cleaners are best for different stucco house washing situations. For general cleaning, we recommend using a solution of water and mild detergent or perhaps even a mixture of chlorine and a good surfactant with water. However, if there’s mildew then you may want to use bleach and possibly a concentrated stucco cleaner that you can pick up at the store.

If you’re unsure about the best solutions to use, a professional cleaning team can help you out.
