Remediation of air pollution can be costly and technically difficult. Many state and local air pollution control agencies have discovered that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contamination. 100% solid epoxy can seal impurities into the concrete with layers of 10 to 100 mils thick. In place, the encapsulation works like an insect trapped in amber. Solids, gasses, and liquids are all trapped inside a solid hard capsule. Impurities are thus able to be left in place, with no hazard to crews that may experienced to work near remove them.
It is highly recommended to choose a white, yellow, or red colorization for the first cover, or “seal cover.” Following topcoats are a contrasting color like gray or brown. In this manner, workers moving around the contaminated areas are alerted when wear has made re-coating necessary. The contrasting colors thus provide a “wear meter.”
100% epoxy has no odor, can continue as thick as needed, and comes in colors as well as clear. When making use of floor seals that can be 20 to 500 mils solid as they repair and level imperfect floor floors, it is critical to consider the elevation of the coating in addition to the length issues of normal roll-on applications. When normal water is poured on a glass, it protrudes above the top at the corners. Pulling a finger although water, one recognizes flattening at the access and exit points due to its surface anxiety. When leveling flooring surfaces, these same ramifications of the epoxy’s surface pressure must be dealt with. In other words “self-levelling,” which is imperfect even for liquids like water, will not produce a smooth top coating of epoxy.
100% epoxy coatings do not shrink and will harden at any elevation it is remaining at after being catalyzed. But special strategies are needed to be able to assure a set surface while filling uneven anomalies in the substrate. Experience has established that by using a squeegee-like action with a very brief nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to leak into low areas while keeping the top flat. Care must be used to apply a straight coat at the top, and too much rolling can cause the top to attempt to contour along the floor’s imperfections.
