8 CONCRETE COVERED DECEMBER 2018 COATINGSPROMAG.COM Concrete Covered C oncrete is everywhere. From roadways and bridges to flooring, walls, and well beyond, the range of potential projects for contractors dealing with some sort of concrete substrate is almost limit- less. But while concrete's versatility provides opportunities, it also presents its own unique challenges. Even for new pours, concrete substrates inherently have high porosity, making moisture ingress a concern. And for older slabs, years of wear and tear and exposure to the elements can quickly complicate any application of a new coating system. "e way I usually put it is this: Concrete is alive," said Bob Stanley, director of industrial brands at coatings manufacturer Rust-Oleum. "It's a living, breathing thing for us. It takes in and gives out moisture. It's porous, so it moves with temperature changes. It also varies from batch to batch, depending on when they pour, so there can be a change in mixtures. ey move it around, especially on larger slabs, so the quality and compo- sition can vary. Different places that are on a slab can behave differently. I tend to think of it as each slab has its own person- ality. Sometimes the elongation or elasticity can move quite a bit in cold temperatures, other times it can be firmer. It's unique, and it's a unique behavior at each pour." Based on those varying personalities, coating a concrete substrate often goes well beyond just selecting the coating. Knowledge of numerous phases and their potential pitfalls is critical, including the importance of moisture measurement, localized repairs, surface preparation, and inspections. Also essential is the selection of proper application tools for each jobsite and maintaining a diligent approach to safety protocols and up-to-date industry standards. To help guide contractors through this lengthy process, CoatingsPro Magazine spoke with industry experts and special- ists across the numerous phases to get the latest intel on how to succeed with modern concrete application projects. Safety Standards e first part of any concrete job for a contractor is typically developing a jobsite safety plan. For safety concerns that cannot be engineered out of the project, the next step is typically using personal protective equipment (PPE). "Like any industry, it's important to assess what tools you are using and what hazards are associated with the job," said Toby Cummings, sales representative at TurtleSkin by Warwick Mills. "If there is loud machinery, make sure ear protection is used, and wear protective gloves or sleeves if handling rebar or sharp tools. And if special equipment, like a waterjet, is being used, make sure the operator is protected." "The way I usually put it is this: Concrete is alive," said Bob Stanley, director of industrial brands at Rust-Oleum. "It's a living, breathing thing for us. It takes in and gives out moisture." When working on concrete substrates, proper personal protective equipment (PPE) may include protective clothing, gloves, goggles, hard hats, ear protection, and respiratory protection, such as from 3M.
