When it comes to protecting your outdoor deck, one of the best things you can do is to waterproof the surface. Waterproofing not only helps to maintain the integrity of the deck, it also helps to increase the lifespan and prevent any costly repairs down the line do to dry rot or mold. However, when it comes to waterproofing, not all waterproofing systems are the same. From AL systems to MC systems, here’s what you need to know about the waterproofing system that is right for you and your deck. The Life Deck AL System, also known as Acrylic Lath, is a deck system that is installed through three separate series of applications. The three applications are then bonded together through a specially formulated acrylic mix and then sealed with waterproof top coat. It is important to note that the AL System works specifically for plywood decks and is not recommended for decks made from oriented strand board. The pros of using an AL deck system is that offers unparalleled strength and durability. In fact, it is the go to system for apartments, hotels and office buildings. If you are looking for unmatched strength for a heavy traffic area, consider using the AL deck system. The MC System is a great option when looking for a flexible concrete waterproofing system. The MC system is a fiber reinforced system that uses three or four separate applications made from a water-based acrylic. This system works great over older concrete systems that may have various cracks or leaks. While the system was designed originally to be used on elevated concrete walking decks, it also makes it great for balconies and roof decks. Pros to this type of system is that is it flexible, durable, and also comes in a variety of colors and textures.
