3. Breathability

While keeping water out is essential, it’s equally important to allow the structure to breathe. Water vapor should be able to escape from the building materials to prevent issues like mold and mildew. A quality water repellent should strike a balance between repelling water and allowing the release of trapped moisture.

4. UV Resistance

Chicago experiences a wide range of weather conditions, including intense sunlight. UV resistance is essential to prevent the degradation of the water repellent over time. Ensure that the product you choose can withstand prolonged sun exposure without losing its effectiveness.

5. Environmental Impact

Consider the environmental impact of the water repellent you choose. Environmentally-friendly options are available, and selecting these products can contribute to your building’s sustainability and reduce your ecological footprint.

6. Longevity

Investing in a water repellent that provides long-term protection is cost-effective in the long run. Assess the expected lifespan of the product and whether it requires frequent reapplication.



Q: How often should a water repellent be reapplied?

A: The frequency of reapplication depends on the specific product you choose. Some water repellents provide long-term protection and may only need reapplication every few years, while others may require more frequent maintenance. It’s essential to follow the manufacturer’s recommendations for reapplication.

Q: Can I apply a water repellent myself, or should I hire a professional?

A: While some water-repellent products are designed for DIY application, it’s often best to hire a professional, especially for larger commercial or industrial buildings. Professionals have the expertise and equipment to ensure proper and even application.

A: Regulations regarding the use of water repellents may vary by location. It’s essential to check with local authorities and building codes to ensure compliance with any relevant regulations.

A: Breathability in water repellents allows trapped moisture within building materials to escape. This prevents issues like mold and mildew and helps maintain the structural integrity of the building.

Q: How do I know if my building needs a water repellent?

A: If your building experiences moisture-related issues, such as water infiltration, mold growth, or deteriorating building materials, it may be a sign that it needs a water repellent. Consult with a professional to assess your specific situation and determine if a water repellent is necessary.
