MAINTENANCE MATTERS materials. Or, for a bolder design, there are metallic pigment coatings offering a deep, distinctive, attractive luster. NON-PUBLIC AREAS The areas used by airport staff and equipment are varied, ranging from loading docks to baggage handling to security. In these areas, aesthetics is of little concern, but safety and durability are paramount. Coatings need to first protect the people that work on them by helping prevent slip-and-fall accidents. In many cases, they need to protect the concrete surface from moisture, road salt, oil and chemical spills. Here, a two-step process is recommended, starting with a concrete sealer and primer. Depending on the location and use of the floor, this would either be a solvent-based urethane or a water-based epoxy. Finishing the floor might be as simple as adding a clear or pigmented coating. But in areas where traction and especially non-slip is important, a safety grip coating is recommended. Numerous grades of slip-resistant coatings are available, from modest to very aggressive, like those found on aircraft carrier decks. Some offer UV and chemical resistance. This may be extreme for a land-based airport, but it illustrates the choices available. When coatings need to be applied in areas that must remain occupied, there are low- or no-VOC formulas, so they can be applied without vacating the facility. The coating that's most appropriate depends upon the specific need of the environment. HANGARS They might not look it, but airport hangars are some of the most punishing environments for concrete floors. Jet aircraft hydraulic fluid is extremely corrosive, while fuel, oil and ultraviolet light also compromise the long-term durability of the floor's look and function. Add to that tire marks from hot aircraft tires and frequently dropped tools and you get the picture of challenges in making a well-done, durable hangar floor. Most airport facility professionals want hangar floors to be very high-gloss and easy to keep clean. Accomplishing that requires a specialized coating system, starting with a primer/sealer, as mentioned above. In these cases, consider a midcoat. For hangars primarily used for storage of light Despite being indoors, these floors are also subject to ultraviolet damage from sunlight streaming in through large windows. Flake broadcast finishes offer endless design possibilities, with different combinations of flake sizes and colors. Coatings need to first protect the people that work on them by helping prevent slip-and-fall accidents. For the topcoat, a specialized urethane retains the color and high-gloss finish, while providing additional protection from tire marks, chemicals and UV.
