Remediation of air pollution can be costly and theoretically difficult. Many state and local air pollution control businesses have discovered that encapsulating contaminated concrete is the most inexpensive and resilient solution for existing contamination. 100% sturdy epoxy can seal impurities into the concrete with tiers of 10 to 100 mils heavy. In effect, the encapsulation works like an insect trapped in amber. Solids, gasses, and fluids are all stuck inside a stable hard capsule. Impurities are thus in a position to be left set up, with no threat 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 coat, or “seal jacket.” Subsequent topcoats are a contrasting color like grey or brown. In this manner, workers active the contaminated floors are alerted when wear has made re-coating necessary. The contrasting colors thus give a “wear meter.”
100% epoxy does not have any odor, can go on as thick as needed, and will come in colors as well as clear. When applying floor seals that may be 20 to 500 mils thick as they repair and level imperfect floor areas, it is critical to consider the elevation of the coating as well as the length and width issues of normal roll-on applications. When water is poured on goblet, it protrudes above the top at the corners. Tugging a finger though the water, one sees flattening at the access and exit items due to its surface pressure. When leveling floor surfaces, these same effects of the epoxy’s surface tension must be dealt with. In other words “self-levelling,” which is incomplete even for liquids like water, will not produce a smooth top coating of epoxy.
100% epoxy coatings do not reduce and can harden at any height it is still left at after being catalyzed. But special strategies are needed in order to assure a flat surface while filling uneven anomalies in the substrate. Experience has decided that using a squeegee-like action with a very brief nap roller (3/16″) creates a pool of epoxy that may be pulled towards you to leak 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 top to attempt to contour over the floor’s imperfections.
