Remediation of air pollution can be costly and theoretically difficult. Many express and local pollution control companies have found that encapsulating contaminated cement is the most economical and long lasting solution for existing contamination. 100% solid epoxy can seal pollutants into the cement with layers of 10 to 100 mils thick. In effect, the encapsulation works like an insect stuck in amber. Solids, gasses, and liquids are all trapped inside a solid hard capsule. Impurities are thus able to be left set up, with no danger to crews that might have had to work in close proximity to remove them.
It is advisable to choose a white, yellow, or red color for the first jacket, or “seal cover.” Following topcoats are a contrasting color like gray or brown. In this manner, workers active 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 solid as needed, and will come 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 floors, it is advisable to consider the height of the finish as well as the length and width issues of normal roll-on applications. When drinking water is poured on a glass, it protrudes above the top at the ends. Tugging a finger though the water, one perceives flattening at the admittance and exit points because of its surface pressure. When leveling flooring surfaces, these same effects of the epoxy’s surface anxiety must be handled. Quite simply “self-levelling,” which is incomplete even for fluids like water, won’t produce a level top layer of epoxy.
100% epoxy coatings do not shrink and can harden at any level it is left at after being catalyzed. But special steps are needed to be able to assure a flat surface while filling up unequal anomalies in the substrate. Experience has established that using a squeegee-like action with a very brief nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to drip into low locations while keeping the top 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 across the floor’s imperfections.
