Remediation of air pollution can be costly and officially difficult. Many state and local air pollution control firms have discovered that encapsulating contaminated concrete is the most cost-effective and long lasting solution for existing contaminants. 100% stable epoxy can seal pollutants into the cement with layers of 10 to 100 mils heavy. In effect, the encapsulation works as an insect captured in amber. Solids, gasses, and liquids are all captured inside a solid hard capsule. Pollutants are thus able to be left in place, with no threat to crews that may have had to work in close proximity to remove them.
It is recommended to choose a white, yellow, or red colorization for the first coat, or “seal coating.” Succeeding topcoats are a contrasting color like grey or brown. In this manner, workers moving around the contaminated floors are alerted when wear has made re-coating necessary. The contrasting colors thus provide a “wear meter.”
100% epoxy does not have any odor, can continue as solid as needed, and comes in colors as well as clear. When applying floor seals that may be 20 to 500 mils heavy as they repair and level imperfect floor areas, it is critical to consider the elevation of the coating as well as the length issues of normal roll-on applications. When drinking water is poured on cup, it protrudes above the top at the edges. Tugging a finger though the water, one sees flattening at the entry and exit details because of its surface tension. When leveling flooring surfaces, these same ramifications of the epoxy’s surface tension must be handled. In other words “self-levelling,” which is imperfect even for fluids like water, will not produce a even top layer of epoxy.
100% epoxy coatings do not shrink and will harden at any level it is left at after being catalyzed. But special strategies are needed to be able to assure a set surface while filling up unequal anomalies in the substrate. Experience has decided that utilizing a squeegee-like motion with a very brief nap roller (3/16″) creates a pool of epoxy that may be pulled towards you to drip into low spots while keeping the top flat. Care can be used to apply an even coat at the surface, and too much moving can cause the surface to attempt to contour along the floor’s imperfections.
