Remediation of air pollution can be expensive and technically difficult. Many condition and local air pollution control firms have discovered that encapsulating contaminated concrete is the most economical and resilient solution for existing contamination. 100% stable epoxy can seal impurities into the concrete with levels of 10 to 100 mils solid. In effect, the encapsulation works as an insect trapped in amber. Solids, gasses, and fluids are all trapped inside a solid hard capsule. Pollutants are thus in a position to be left in place, with no hazard to crews that may have had to work in close proximity to remove them.
It is a good idea to choose a white, yellowish, or red color for the first cover, or “seal coat.” 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 give a “wear meter.”
100% epoxy does not have any odor, can continue as dense as needed, and will come in colors as well as clear. When making use of floor seals that can be 20 to 500 mils dense as they repair and level imperfect floor floors, it is critical to consider the level of the covering in addition to the length and width issues of normal roll-on applications. When normal water is poured on goblet, it protrudes above the surface at the ends. Pulling a finger though the water, one sees flattening at the entrance and exit tips due to its surface pressure. When leveling surfaces, these same ramifications of the epoxy’s surface stress must be handled. In other words “self-levelling,” which is incomplete even for liquids like water, won’t produce a chiseled top coating of epoxy.
100% epoxy coatings do not shrink and can harden at any level it is left at after being catalyzed. But special types of procedures are needed to be able to assure a flat surface while filling unequal anomalies in the substrate. Experience has decided that by using a squeegee-like movement with a very brief nap roller (3/16″) creates a pool of epoxy that may be pulled in your direction to drip into low areas while keeping the top flat. Care must be used to apply an even coat at the top, and too much rolling can cause the top to try to contour along the floor’s imperfections.
