Remediation of air pollution can be costly and theoretically difficult. Many state and local air pollution control firms have found that encapsulating contaminated concrete is the most cost-effective and long lasting solution for existing contamination. 100% stable epoxy can seal impurities into the concrete with levels of 10 to 100 mils dense. In effect, the encapsulation works as an insect caught in amber. Solids, gasses, and fluids are all caught inside a sound hard capsule. Impurities are thus able to be left in place, with no risk to crews that might experienced to work near remove them.
It is a good idea to choose a white, yellow, or red colorization for the first cover, or “seal overcoat.” 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 give a “wear meter.”
100% epoxy has no odor, can continue as heavy as needed, and will come in colors as well as clear. When applying floor seals that can be 20 to 500 mils heavy as they repair and level imperfect floor surfaces, it is critical to consider the height of the finish as well as the length issues of normal roll-on applications. When normal water is poured on wine glass, it protrudes above the top at the edges. Tugging a finger though the water, one considers flattening at the entrance and exit things because of its surface tension. When leveling floor surfaces, these same effects of the epoxy’s surface pressure must be handled. In other words “self-levelling,” which is imperfect even for fluids like water, will not produce a toned top coating of epoxy.
100% epoxy coatings do not shrink and will harden at any elevation it is kept at after being catalyzed. But special steps are needed to be able to assure a set surface while filling up uneven anomalies in the substrate. Experience has established that using a squeegee-like motion with a very short nap roller (3/16″) creates a pool of epoxy that may 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 surface, and too much rolling can cause the surface to try to contour across the floor’s imperfections.
