Remediation of air pollution can be costly and technically difficult. Many express and local pollution control firms have found that encapsulating contaminated concrete is the most inexpensive and long lasting solution for existing contamination. 100% solid epoxy can seal contaminants into the concrete with levels of 10 to 100 mils thick. In place, the encapsulation works like an insect stuck in amber. Solids, gasses, and fluids are all captured inside a stable hard capsule. Pollutants are thus able to be left in place, with no hazard to crews that may have had to work near remove them.
It is advisable to choose a white, yellow, or red colorization for the first cover, or “seal coating.” Subsequent topcoats are a contrasting color like grey or brown. In this manner, 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 heavy as needed, and will come in colors as well as clear. When applying floor seals that may be 20 to 500 mils dense as they repair and level imperfect floor surfaces, it is critical to consider the elevation of the layer as well as the length and width issues of normal roll-on applications. When water is poured on wine glass, it protrudes above the top at the corners. Tugging a finger though the water, one perceives flattening at the entrance and exit points due to its surface tension. When leveling flooring, these same ramifications of the epoxy’s surface tension must be handled. Quite simply “self-levelling,” which is imperfect even for liquids like water, will not produce a flat top covering 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 set surface while filling unequal anomalies in the substrate. Experience has driven that utilizing a squeegee-like action with an extremely short nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to drip into low spots while keeping the surface flat. Care must be used to apply an even coat at the surface, and too much moving can cause the surface to try to contour over the floor’s imperfections.
