A Step-by-Step Guide on How to Clean Stucco: Power Washing and Maintenance Tips

When it comes to maintaining the exterior of your stucco house, cleaning is a crucial step that can't be ignored. Failure to do so can lead to water damage, mold growth, and even structural issues. In this article, we'll provide you with a comprehensive guide on how to clean stucco, including power washing methods and essential maintenance tips.

Before You Begin: Inspect Your Stucco Walls

Before diving into the cleaning process, it's essential to inspect your stucco walls for any cracks or damage. If you notice any deep cracks, it's recommended to contact a professional to fill them before proceeding with cleaning. Ignoring cracks can allow water to seep inside and cause mold growth.

Pre-Cleaning Preparation

To ensure effective cleaning, remove any loose dirt, grime, or grease from the stucco surface using your hands or a wire brush. This will prevent the repair compound from adhering properly. Next, mix Stucco Patch with water in a bucket, tub, or container to create a workable paste.

Cleaning the Crack

Use a wire brush to remove any loose dirt or debris from the crack. Back-cut the crack to its base, making sure it's slightly broader than the top. Then, chisel the edges perpendicular to the wall using a cold chisel and hammer. Increase the crack's width to at least 1/4 inch to ensure proper filling.

Power Washing Methods

To power wash your stucco house, follow these steps:

1. Choose the right cleaner: Select a mild detergent specifically designed for cleaning stucco.

2. Use a low-pressure setting: Avoid using high-pressure settings, as they can damage the stucco surface.

3. Test a small area first: Before washing the entire house, test the cleaner on a small, inconspicuous area to ensure it doesn't cause discoloration or damage.

4. Use a wide fan tip: A wide fan tip is better suited for cleaning large areas like stucco walls.
