Remediation of air pollution can be costly and theoretically difficult. Many status and local air pollution control organizations have found that encapsulating contaminated concrete is the most economical and long lasting solution for existing contamination. 100% stable epoxy can seal contaminants into the concrete with tiers of 10 to 100 mils dense. In effect, the encapsulation works as an insect trapped in amber. Solids, gasses, and fluids are all captured inside a solid hard capsule. Pollutants are thus able to be left set up, with no danger to crews that may experienced to work in close proximity to remove them.
It is highly recommended to choose a white, yellow, or red color for the first cover, or “seal cover.” Succeeding topcoats are a contrasting color like gray or brown. In this way, 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 go on as solid as needed, and comes in colors as well as clear. When applying floor seals that can be 20 to 500 mils thick as they repair and level imperfect floor floors, it is advisable to consider the height of the covering as well as the length and width issues of normal roll-on applications. When normal water is poured on glass, it protrudes above the surface at the edges. Tugging a finger though the water, one views flattening at the admittance and exit factors due to its surface tension. When leveling surfaces, these same effects of the epoxy’s surface tension must be dealt with. In other words “self-levelling,” which is imperfect even for fluids like water, won’t produce a chiseled top layer of epoxy.
100% epoxy coatings do not reduce and will harden at any height it is left at after being catalyzed. But special procedures are needed to be able to assure a flat surface while filling up uneven anomalies in the substrate. Experience has driven that utilizing a squeegee-like movement 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 can be used to apply a straight coat at the top, and too much moving can cause the surface to try to contour along the floor’s imperfections.
