How to Remove Moss From Stucco

1. Safety Precautions:

- Put on protective clothing, gloves, and eye protection.

- Ensure good ventilation, especially if using chemical cleaners.

2. Preparation:

- Sweep or vacuum the stucco surface to remove loose dirt and debris.

- Rinse the stucco surface with a garden hose to remove surface dirt and mold spores.

3. Natural Stain Removal:

- For small areas of moss, try scrubbing with a mixture of warm water and dish soap using a soft brush.

- Rinse thoroughly with water.

4. Chemical Cleaning (for heavier moss):

- Use a commercial moss cleaner or a mixture of 1 part bleach and 4 parts water.

- Test a small area to check if the stucco material is compatible with the cleaner.

- Spray or apply the cleaner to the stucco surface and leave it for the recommended duration (usually 10-15 minutes).

- Rinse the surface thoroughly with water to remove the cleaner and loosened moss.

5. Rinse and Inspect:

- Use a garden hose to rinse the stucco surface until the moss and cleaner residue is removed.

- Inspect the area to ensure all the moss has been removed.

6. Protect the Stucco:

- Allow the stucco to dry completely.

- Consider applying a sealant or waterproofer specifically designed for stucco surfaces to help prevent future moss growth.

Remember that removing moss may temporarily alter the appearance of the stucco, but it's essential for maintaining the health and longevity of your exterior walls. If the damage caused by moss is extensive, it may be best to consult with a professional contractor.
