Why Waterproof? 3 Benefits for Long-Lasting Decking
Outdoor living spaces are increasingly a priority for consumers everywhere—and professionals can help improve these spaces with optimized waterproofing services and coating products.
Recent research shows that the global decking market is on a growth trajectory, driven by increased consumer interest in outdoor living spaces and home renovations.
It’s easy to understand why: Whether it’s wood, concrete, or other material, outdoor decking is an ideal way to enhance livability and functionality of any property, be it a residential home, an apartment complex, commercial application or beyond.
But decks are continuously exposed to the elements. Depending on the climate, decks must withstand wind, rain, hail, snow, and other forms of weatherization that can cause premature rotting or degradation unless the proper measures are taken. It’s what makes the application of a waterproof coating an important step in the total process.
Whether you're a building owner or facility manager seeking durable waterproofing with low maintenance, a homeowner enhancing the value of your outdoor living space, or a professional contractor looking to bolster your decking services, it’s important to know the benefits of high-performance waterproofing systems. Let’s explore a few of them:
#1: Waterproof Coatings Extend Durability and Longevity
First, it’s important to stress the importance of waterproofing when it comes to the longevity and durability of a deck. High-performance waterproof coatings provide an essential layer of protection for the deck substrate, be it wood, concrete, or other material. Successful application can contribute to better protection against even some of the harshest environmental conditions.
Consider: A concrete balcony or rooftop deck in a multifamily high-rise near the ocean will be continuously subjected to high winds, salt spray, and other intense conditions. A high-performance coating here is essential not only to their ability to hold up over the long term, but to the safety of the inhabitants as well.
Meanwhile, a family patio at a home in the Midwest won’t be contending with seaside conditions, but it may face snowstorms in the winter months, storms and showers in the spring, and intense heat in the summers. Over time, these conditions can wear down a deck surface that has not been treated with a high-performance coating, necessitating frequent or early repair or replacement.
Additionally, seasonal temperature swings have the potential to cause surface spalling, cracks, scaling, and structural damage, and water trapped in a concrete surface will inherently expand under freezing conditions. Waterproof coatings keep water out in the first place, reducing the potential for freeze-thaw damage.
#2: Waterproof Coatings Can Boost Aesthetic Appeal
A waterproof coating’s role can involve more than performance against the elements, and can in fact be another way to enhance the aesthetics of the outdoor space.
Many waterproof coatings are available in decorative finish options, including solid colors, quartz or flake systems, different textures, and more. Whether for individual homeowners or architects designing commercial spaces, these options enable personalization and visual appeal to a space that may have otherwise remained gray.
#3: Waterproof Coatings Enhance Surface Performance
Depending on the location of the deck, excessive foot traffic might be a consideration for the application of a waterproof coating. The right coating should provide protection against the elements, as well as a safe, walkable surface for pedestrians or inhabitants.
Many high-performance deck coatings can include textured or slip-resistant finishes, whichreduce slip hazards when the surface is wet, helping to improve overall safety around pools, patios, and balconies.
#4: Waterproof Coatings Help Prevent Microbial Growth
Water penetration in concrete, wood, or other surfaces not only can impact structural integrity but can also create opportunities for other safety hazards. Trapped moisture can contribute to mold and mildew growth, surface mineral deposits, and staining and discoloration.
Such issues can affect both the aesthetics and performance of the surface and, in some cases, compromise safety. Waterproof coatings can help prevent these issues, making for a cleaner and healthier surface over the long term.
How to Select a High-Performance Waterproofing System
With the benefits of a waterproof coating in mind, it’s important to pair the right system with the right application.
The effectiveness of a waterproofing system can be determined by identifying the substrate, anticipated foot traffic, weather conditions, and specific use. Many choices are available to professionals, including vinyl systems, polymer systems, epoxy systems, and cementitious systems. Some of these options may be suitable for certain applications, but not for others, making it important to properly vet your options.
Cementitious systems, for example, stand out for a few reasons. They provide broad coverage for many conditions and applications and are a practical and popular choice among waterproofing professionals. Applications include high-traffic areas such as pedestrian balconies, rooftop decks, and stairways, as well as areas designed to receive a concrete topper, pavers, or ceramic tiles such as plaza/podium decks, roof decks and pool decks—providing long-lasting protection and aesthetic appeal.
When in doubt, professionals can consult with relevant industry standards. For example, general compliance with the International Building Code (IBC), the International Residential Code (IRC), and others means you can be confident in the product’s overall durability and weatherability performance.For a project in hurricane-prone Florida, it’s important to look for a waterproof coating that meets the Florida Building Code’s elevated performance standards. By contrast, California—which in recent years has experienced numerous record-setting wildfire seasons—typically requires products that meet the California Residential Building Code, Class A fire ratings, BML listings for fire performance, and other important fire performance criteria.
