Water damage is one of the biggest threats facing homes with stucco siding. If water gets behind the stucco, it can seep in and slowly degrade the structural integrity of your walls from the inside out. Maybe you’ve noticed tiny hairline cracks starting to form in your stucco over the years or seen brownish stains appearing where moisture has infiltrated. Or perhaps a heavy rainstorm managed to leave dark spots where water penetrated the stucco’s surface.
Whatever signs of water damage you may be seeing, it’s crucial to act fast to waterproof your stucco before the problems worsen. In this blog post, I’ll share several simple and inexpensive methods on how to waterproof stucco and prevent further moisture intrusion, from applying waterproof paint or sealant to making small repairs around windows, doors, and rooflines. By following the steps outlined below, you can keep your stucco safely dry and avoid potential damage that could become costly to repair down the road.
9 Best Methods on How to Waterproof Stucco
1. Use Waterproof Paint:
One of the easiest and most effective ways to waterproof stucco is by applying a coat of high-quality, waterproof paint. Look for paints specifically designed for stucco or masonry surfaces that have excellent water-resistant properties. It’s essential to clean your stucco thoroughly before painting it. You can use a power washer or scrub with a stiff brush and detergent to remove any dirt, mildew, or old paint that could affect the adhesion of the new coat. Once clean and dry, apply two coats of waterproof paint using a roller or brush for optimal coverage.
2. Apply Waterproof Sealant:
A sealant is another straightforward and effective way to waterproof stucco. Much like paint, there are specially formulated sealants designed for stucco surfaces that provide a durable waterproof barrier. Before applying the sealant, make sure to clean and dry your stucco thoroughly. Apply the sealant using a paintbrush or roller, covering all areas evenly.
3. Repair Cracks and Holes:
Hairline cracks and small holes in the stucco are common entry points for moisture. It’s essential to repair these imperfections before waterproofing your stucco properly. You can use a stucco patching compound and a putty knife to fill in any cracks or holes. Once the compound dries, sand it down for a smooth finish.
4. Address Window and Door Flashings:
The areas around windows and doors are particularly vulnerable to water intrusion. Check the flashings, which are thin metal pieces that direct water away from these openings, and make sure they are securely attached and free of any damage or corrosion. If needed, replace them with new ones. This will help to prevent water from seeping in and potentially compromising your stucco.
5. Inspect and Clean Gutters:
Clogged gutters can cause water to back up, overflow, and soak into your stucco. It’s essential to regularly inspect and clean your gutters and downspouts to ensure proper drainage away from your home’s exterior walls. This will help to prevent water from pooling near your stucco and potentially causing damage.
6. Fix Roof Leaks:
A leaky roof is another common cause of water intrusion in homes with stucco siding. Regularly inspect your roof for any signs of damage or deterioration, such as missing shingles or cracked flashing. If you notice any issues, have them repaired by a professional roofer to prevent water from seeping into your stucco. Fixing roof leaks will also help to maintain the overall integrity of your home’s structure.
7. Improve Landscaping:
Believe it or not, the landscaping around your home can impact how much water seeps into your stucco. If you have plants or trees too close to your exterior walls, they can trap moisture and create a damp environment that can lead to water damage. Make sure to maintain a distance of at least 2 feet between your plants and stucco to allow for proper air circulation and prevent moisture buildup.
8. Install Weatherproofing Membrane:
A weatherproofing membrane is a thin, waterproof material that can be applied directly onto your stucco walls before adding new siding or paint. This additional layer provides an extra barrier against moisture and can significantly improve the waterproofing of your stucco. It’s best to have a professional install the membrane for optimal results.
9. Consider Repair or Replacement:
If you notice severe water damage caused by prolonged exposure or neglect, it might be time to consider repairing or replacing your stucco entirely. While this may seem like a significant investment, it’s crucial to address any structural issues to prevent further damage and maintain the safety and value of your home. Consult with a professional contractor for expert advice on the best solution for your specific situation.
By following these nine methods on how to waterproof stucco, you can protect your home from water damage and keep it structurally sound for years to come. Remember to regularly inspect and maintain your stucco to catch any potential issues early on and address them promptly.
With proper care, you can ensure that your stucco remains a beautiful and durable exterior finish for your home. So don’t delay, take the necessary steps to waterproof your stucco today! Your future self will thank you. Happy waterproofing!
Additional Tips and Tricks to Waterproof Stucco
- If you’re planning on painting your stucco, choose a paint specifically designed for masonry or stucco. These paints are more flexible and breathable, allowing moisture to escape without compromising the waterproofing.
- Make sure to properly clean and prep your stucco before applying any waterproofing products. This includes removing any dirt, debris, or algae growth from the surface.
- When applying waterproofing sealant, make sure to work in small sections and apply it evenly with a brush or roller. This will ensure that the product is evenly distributed and provides maximum protection.
- If you notice any cracks or damage in your stucco, repair them before applying waterproofing products. These areas are vulnerable to water seepage and can compromise the effectiveness of the waterproofing.
- Consider using a breathable waterproofing membrane instead of an acrylic sealant. These membranes allow moisture to escape while still providing a barrier against water intrusion.

- Regularly inspect your stucco for any signs of water damage, such as discoloration or mold growth. If you notice any issues, address them immediately to prevent further damage.
- In areas with heavy rain or high humidity, consider using a vapor barrier behind the stucco to prevent moisture from seeping through the walls.
- Consider using a combination of waterproofing methods, such as both an acrylic sealant and a breathable membrane, for maximum protection against water intrusion.
- Remember to follow the manufacturer’s instructions when applying any waterproofing products, and always wear proper protective gear during application.
By following these additional tips and tricks, you can ensure that your stucco is properly waterproofed and protected from any potential water damage. So, it is always a good idea to take extra steps and precautions for maximum protection. Happy waterproofing!
