Two Systems from Westcoat Specialty Coating Systems to Combat Moisture Issues

Dark and light areas of this concrete overlay give a geometric look to the space.Second-story decks are popular outdoor spaces in both residential and commercial buildings, but unless they are waterproofed in some fashion, the space underneath can essentially be useless or even get destroyed. In order to help combat moisture problems, Westcoat Specialty Coating Systems offers two popular and proven waterproofing coating systems: ALX and MACoat.

ALX is specially designed for application over plywood substrates. With that in mind, the coating includes a reinforced galvanized metal lath. The lath only weighs 2.5 pounds per square foot.

ALX can also be used for interior applications as a decorative topping designed to resurface a plain plywood subfloor into a decorative, water-resistant, concretelike finish. It can be used for living areas, lobbies, offices, restaurants and hotels or wherever a thin, decorative and durable floor finish is desired over plywood.

MACoat on the other hand, is designed to be applied over concrete surfaces. It uses a fiber lath for reinforcement and as a result is very lightweight.

Despite their obvious differences, the two coatings are pretty similar, according to their manufacturer. “From a performance standpoint, they do the same thing,” says Matt Ranzau, a sales representative for Westcoat who specializes in waterproof coatings.

Ranzau lists three main advantages they have compared to polyurethane coatings: they are environmentally friendly, fast-drying and offer a variety of decorative finishes. “Westcoat waterproof deck coatings can be made to look like tile, slate or flagstone, and in any color you can imagine,” he notes. “ALX and MACoat not only offer outstanding waterproofing capabilities but also enhance the look of balconies, walkways, decks and other high-traffic areas.”

The products can only be applied between 55 F and 95 F, and depending on temperature, each layer takes two to six hours to dry. The surface can also be opened up to pedestrian traffic for use between coats.

For contractors who are familiar with resurfacing methods, applying ALX or MACoat is a fairly standard job.

“Many of the components in our waterproof systems are what a lot of resurfacing contractors are already using,” Ranzau says. “The systems are going to have a familiarity that will result in an easier installation and potentially better profit margin.”
