What to Know About Waterproofing Stucco

When it comes to protecting the exterior of a home from water damage, stucco should be given special attention. This popular building material is known for its durability and aesthetic appeal, but it’s also porous and vulnerable to water infiltration. This can cause significant problems. Thankfully, there are several different methods for waterproofing it.

The Importance of Waterproofing Stucco

Water damage can deteriorate stucco over time, compromising the integrity of the structure. As water seeps in, it can damage a house’s walls and insulation, ultimately leading to higher energy bills (and eventual costly repairs). Water intrusion can also create a breeding ground for mold and mildew which damages the appearance of a home and poses health risks for its residents.

How to Waterproof Stucco 

Exterior stucco can be waterproofed with the application of a specialized membrane or a liquid waterproofing product to serve as a barrier, creating a protective layer that will help stop water from being absorbed by the stucco. Another option is using a waterproof coating or sealant to repel moisture. Experts recommend using a rain screen system as it lets water drain away from a home’s walls.

A home’s interior stucco also should be waterproofed. This process involves installing a vapor barrier, such as plastic sheeting placed behind the stucco to prevent water damage. 

Professional Waterproofing vs. DIY Approach

While a DIY approach may save a homeowner money, hiring professionals for this offers several advantages. They have the expertise and experience to assess a home’s specific needs, and they’re equipped to recommend the most effective waterproofing solutions. 

With their training and access to industry-specialized tools and materials, professionals also ensure a high-quality and long-lasting result.

Structural Preservation

Ensuring stucco is properly waterproofed is crucial for maintaining the structural integrity of a home. By taking proactive measures, mold growth can be prevented, a home can be more energy efficient, and a homeowner can save money both by keeping their heating and cooling costs low and avoiding costly repairs. With properly waterproofed stucco, a home will remain strong and beautiful for years to come.
