Deck waterproofing may seem like just an optional add-on, but it’s more important than many might realize. While a deck or balcony can last several years without waterproofing, its lifespan and safety will become severely limited once wind, rain, and weather start taking their toll. As a result, deck waterproofing isn’t just an add-on—it’s an essential!

Thankfully, balcony deck waterproofing is not only quick and affordable but also comes with many benefits beyond just protecting your investment. Read on to learn more about the benefits of our deck waterproofing process.

What Is Balcony Deck Waterproofing?

Balcony deck waterproofing is a durable surface treatment that seals your deck or balcony’s surface from water and wear. Most deck waterproofing solutions are a multi-layer waterproofing system that takes care of your deck for up to 25-30 years when properly maintained.

During that time, your decking material will remain sealed and protected from harmful water damage and day-to-day wear and tear.

There’s more to balcony deck waterproofing than just protecting your deck, however. Find out more in the next section as we explore some of the hidden benefits of protecting your deck or balcony!

5 Benefits of Balcony Deck Waterproofing

Keeping your deck dry does more than prevent water damage. From avoiding expensive repairs to keeping your favorite plants and flowers, deck waterproofing comes with many benefits.

1. Protects Against Water Damage

While it may seem a bit obvious, protecting against water damage is the biggest benefit of deck waterproofing. In fact, most other benefits of deck waterproofing stem from this benefit alone. Protecting your deck against water does more than just protect the deck itself; it can also prevent water damage from infiltrating your home and surrounding structures, increase safety for foot traffic, and even prevent costly (and dangerous) rot and mold.

Needless to say, avoiding water damage is very important and, in the case of waterproof coatings, a great investment, but the benefits aren’t limited to keeping out water!

2. Prevents Wear and Tear

Foot traffic, furniture, and other heavy loads can cause wear and tear to your deck over time. A durable waterproof coating is one way to protect your deck against this kind of damage while also sealing your deck from moisture. Like with water damage, wear and tear can gradually degrade your deck over time. While perhaps not as extreme as rot or mold, worn surfaces have a poor appearance and, depending on the deck material, can even pose a safety hazard through splinters and cracks.

3. Improves Safety

Waterproofing improves safety in many ways. In addition to keeping your deck free of slippery surfaces caused by standing water, waterproof coatings also create a high-traction surface for regular foot traffic. Further, by preventing rot and decay caused by water damage, waterproofing also preserves the structural integrity—and, therefore, overall safety—of your deck or balcony.

4. Saves Money and Expensive Repairs

Despite a small upfront cost, waterproofing can save thousands of dollars in costly repairs and replacements over the years. By effectively sealing your deck from damage caused by water, wear, and other elements, waterproofing can increase the lifespan of your deck by many years. Untreated decks and balconies often require expensive and time-consuming repairs after only a few years of outside exposure.

As we’ve mentioned once already, waterproofing can also help prevent water infiltration and damage to surrounding homes and structures. This benefit only leads to further savings as your waterproof surface protects your entire property.

5. Better for Plants and Other Uses

Plants, fountains, and other water-based outdoor features aren’t always practical for untreated surfaces. With a waterproof coating, however, you can keep all of your favorite plants, flowers, and deck decor without having to worry about damage caused by water runoff. Keeping plants can also double the protection by absorbing some of the water that would otherwise reach your deck’s surface.

The Balcony Deck Waterproofing Process

Though waterproofing is relatively straightforward, some of the prep work can be a bit complicated. Make sure you understand what goes into balcony deck waterproofing before you attempt to DIY!

1. Cleaning and Prep Work

Waterproof coatings require a clean, unfinished surface in order to adhere and coat properly. Before waterproofing, our professionals thoroughly clean and treat the existing surface. In some cases, existing or worn finishes also need to be stripped and removed before waterproofing can continue.

2. Corner and Edge Treatments

The prep work isn’t done yet! After cleaning and stripping the surface, the corners of your deck and balcony will require a preliminary waterproofing. This step is important for multiple reasons:

  • ● First, falling water tends to collect towards corners and edges, making these areas especially prone to water damage and infiltration.
  • ● Second, corners and edges present many nooks and crannies for water to enter, making it crucial to give these areas extra attention.

While some waterproofing companies might perform this step by applying a first coat of waterproofing to these areas, our professionals use heavy-duty mesh strips to reinforce corners, edges, and drains.

3. Applying Waterproofing

Finally, it’s time for waterproofing. With the surfaces cleaned, stripped, and reinforced, waterproofing is applied in one or two coats. As you might imagine, prep work takes up most of the waterproofing process. Once it’s time to apply the coating, the process moves along very quickly; apart from setting time, most decks and balconies are usable within a day after waterproofing!

5 step system:

  1. 1. Plywood – make sure that the plywood is the proper thickness and quality and free from dry rot or damage
  2. 2. Metal Lathe – For rigidity
  3. 3. Waterproof silica cement – Fills the lathe and provides the first waterproof layer
  4. 4. Fiberglass and resin – Provides the second waterproof layer and prevents cracking
  5. 5. Waterproof silica cement – 2nd coat of cement for another waterproof layer
  6. 6. Texture and Sealer – Different finishing choices are available and finish with a colored deck sealer.

4. Long-Term Maintenance

Though waterproof coatings are relatively low-maintenance, they still wear down over time. As a result, you’ll likely need to reseal the waterproofing every 5 years with cement deck sealer. With prep work done right the first time, however, reapplications are easy, quick, and inexpensive. In the meantime, you can extend the life of both your coating and outdoor surface by keeping it clean, shaded, and free of water whenever possible.
