Remediation of air pollution can be expensive and technically difficult. Many talk about and local air pollution control companies have discovered that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contamination. 100% solid epoxy can seal pollutants into the concrete with layers of 10 to 100 mils thick. In effect, the encapsulation works like an insect trapped in amber. Solids, gasses, and liquids are all caught inside a stable hard capsule. Impurities are thus able to be left in place, with no danger to crews that might have had to work in close proximity to remove them.
It is recommended to choose a white, yellow, or red color for the first coating, or “seal layer.” Succeeding topcoats are a contrasting color like gray or brown. In this manner, workers moving around the contaminated surfaces 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 heavy as needed, and comes in colors as well as clear. When making use of floor seals that may be 20 to 500 mils solid as they repair and level imperfect floor areas, it is advisable to consider the elevation of the coating in addition to the length and width issues of normal roll-on applications. When normal water is poured on cup, it protrudes above the top at the corners. Tugging a finger though the water, one sees flattening at the entry and exit details due to its surface pressure. When leveling surfaces, these same effects of the epoxy’s surface pressure must be handled. In other words “self-levelling,” which is imperfect even for liquids like water, will not produce a flat top covering of epoxy.
100% epoxy coatings do not reduce and can harden at any level it is remaining at after being catalyzed. But special methods are needed to be able to assure a set surface while filling unequal anomalies in the substrate. Experience has identified that using a squeegee-like motion with a very short nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to leak into low spots while keeping the surface flat. Care must be used to apply an even coat at the top, and too much rolling can cause the top to attempt to contour over the floor’s imperfections.
