How to Waterproof Deck Surfaces with Liquid Rubber & Why It's Superior

As you enjoy the great outdoors from the comfort of your deck, the last thing you want to worry about is damage from water and harsh weather conditions. Luckily, there's a dependable solution to help you safeguard your favorite outdoor space: Liquid Rubber. This modern-day option is not only affordable and easy to use, but also VOC-free and non-toxic, making it an ideal choice for DIY enthusiasts. Let's delve into the process of how to waterproof deck surfaces using Liquid Rubber.

 

 

Understanding Liquid Rubber

Liquid Rubber, as the term suggests, is a liquid-based coating that, when applied, hardens to form a robust waterproof membrane. This innovative product has its roots in bitumen, a naturally occurring, waterproof substance used over centuries in combination with materials like straw and rag felt to create durable roofing.

The commercial production of liquid roof coating started about a century ago. It was only from the 1960s that substances like emulsions, acrylics, and unsaturated polyesters began to be widely used, marking a significant improvement in product quality. By the 1980s, polyurethane coating, the chemical basis of Liquid Rubber, was developed, opening a new chapter in waterproofing technology.

Liquid Rubber: A Versatile, Effective Compound

Liquid Rubber has versatility as a compound. It's primarily used as a protective barrier against corrosion, a seal against air, and a waterproofing solution for various surfaces. From stone and concrete to wood and PVC, Liquid Rubber can adhere to almost any surface that isn't oil-based. This means you can apply it on your deck, roof, driveway, pathways, and even your garage.

Once applied, Liquid Rubber cures into a waterproof membrane that is flexible and that won’t crack or peel over time. Unlike traditional waterproofing methods, there are no joins where water seepage can occur. Its seamless nature also makes it suitable for unconventional places like the sides of buildings or underneath a bridge.

Preparation for Application

Applying Liquid Rubber Deck Coatings require some initial preparation to ensure optimal results. The surface should be clean, dry, and free of dirt, silicone, loose paint, rust, oil, grease, coal tar, or other contaminants. For concrete surfaces, etching, power washing, and complete drying are necessary.

• Wood surfaces should be cleared of mildew and organic growth using Liquid Rubber Deck and Patio Cleaner.
• Secure raised nail heads, deck screws, and loose boards and fill imperfections such as screw holes, knots, and splits in the wood with a high-quality wood filler. Replace damaged and rotting boards and remove loose splinters.
• For fiberglass or vinyl, remove all shine by scuffing the surface, clean with mild soap and water, and wipe with a white rag dampened with acetone to condition the surface.

Application Process of Liquid Rubber

While it might sound complicated, using Liquid Rubber isn't challenging if you follow the right process. The first step is surface preparation, which involves cleaning the area to remove oil, dirt, dust, or any other contaminants. A clean, dry surface ensures optimal adherence of the product.

• You can apply Liquid Rubber just like any other water-based paint using tools such as a brush, broom or a roller.
• It even works over old coats of Liquid Rubber. But it’s not ideal or suited for surfaces that are silicone, glossy or smooth, and it won’t adhere well to oil-based paints or varnishes, either. 
• For best results, apply a minimum final thickness of one gallon for every 50 square feet in three to four thick coats.
• High traffic or porous areas may require a gallon for every 30 square feet.
• Once applied, the product takes approximately 8 hours to dry under conditions of 20 degrees Celsius.

Safety & Durability of Liquid Rubber

Despite its robustness, Liquid Rubber is surprisingly safe to use. Its water-based formulation means there's no need for protective clothing, although wearing old clothes and gloves is advisable due to the difficulty of removing liquid rubber from fabrics. If it comes into contact with your skin, simply use a little bit of baby oil and then thoroughly wash any contact surface. 

While the fumes aren't harmful, wearing a mask in unventilated areas is recommended. In terms of durability, you can expect to reapply Liquid Rubber once every decade, depending on factors like exposure to UV rays and corrosive substances.

Comparing Liquid Rubber with Other Decking Finishes

Liquid Rubber stands out as a cost-effective, practical solution for homeowners looking to waterproof their decks. Unlike many other types of deck coating options, Liquid Rubber is effortless to repair and clean.

Liquid decks are also seamless, providing a higher level of waterproofing. However, keep in mind that it requires specific conditions for application, including the absence of excess moisture, direct sunlight, and cold temperatures.

The Benefits of Liquid Rubber Deck Coating

Liquid Rubber deck coating is a high-performance product that provides a visually pleasing, economical, and walkable surface for various low-traffic areas. You can use it on your deck, patios, steps, walkways, pool areas, and even basement floors.
