Types of Stucco Finishes and Cleaners to Use
Cement plaster is used for stucco finishes. It’s commonly applied to siding, walls, and many exterior sides of any buildings. They form a nice texture and require less effort to clean besides being a durable finish. But, of course, they come in different types.
Consequently, you must know their types to clean them appropriately. For instance, you can’t apply your pressure washer on synthetic stucco finishes. It might probably damage the surface. So, here’s what you should know about the different types.
Namely, there’re two types:
- Traditional Stucco
- Synthetic Stucco
1. Synthetic Stucco
This kind of stucco utilizes acrylic that resists water damage. It dries uniformly, fast and it can be used over foam board instead of mesh. Furthermore, acrylic resin adds stucco movement, reducing the chances of breaking and cracking.
What Cleaners to Use for Synthetic Stucco Finish?
When it comes to cleaning synthetic stucco, you should never use the pressure washing approach. Instead, use a gentle brush to avoid breaking or damaging the surface. Moreover, the rinsing and washing process should be done gently as well.
Recommended synthetic stucco finish cleaner on our list: Wet and Forget Stucco Cleaner
2. Traditional Stucco
When you combine sand and lime with water, that’s what traditional stucco is. It’s durable because of the cement the portion mixed in it. And the lime portion keeps it flexible to shape. Some manufacturers might add glass fibers or acrylics just to make it stronger. And, that’s the way traditional stucco is reinforced.
So, it’s excellently a versatile option for those expecting a smoother and rough texture on the surface. Finally, if you can understand the right water mixture ratio and thus install it properly, it will last up to 5 decades without damaging the surface.
What Cleaners to Use for Traditional Stucco Finish?
Well, it’s all the same for both of the types of stucco. But, specifically, you can use a pressure washer on the traditional finish as it tends to be stronger and durable.

Stucco Cleaner Buying Guide: Things to Consider
Situations are not the same for everyone. It varies from person to person and based on that a certain product might not serve you the best if not chosen carefully. That’s why we’re giving you a few important things you should consider before finally purchasing one.
So, you don’t have to regret it later at all!
1. Ease of Use
While some cleaner requires a spray system, others don’t. So, if you’re a person without a sprayer, buying one that requires it, won’t be able to handle that comfortably. Consequently, if the cleaner itself doesn’t do a very good job, you shouldn’t really be able to see its magic!
Besides, some of them come ready to use, while others don’t. So, they require diluting with water to create a working solution.
2. Action Duration
For instance, 30 SECONDS’s products work very fast. While our top pick requires about 24 hours. Fast-acting products are good for those in rushes. But if you can wait and use a slow dissolving one, you will be surprised by its performance.
Because you know that it takes time to remove something tougher, right?
3. Safety
Saving the home surroundings is as important as cleaning your stucco exterior. So, you must pick one that doesn’t harm the living of the shrubs and grass around the landscape. Moreover, animal life’s matter!
Hopefully, you get all those cared already with one of them on our list!
4. Amount
Consider the purpose area of the application. Several products offer multiple package options for large surface area applications. Hence, making an informed decision about the right package would release the work agony and keep the process fast and simple.
