Remediation of air pollution can be costly and officially difficult. Many state and local air pollution control organizations have found that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contamination. 100% sound epoxy can seal contaminants into the cement with levels of 10 to 100 mils thick. In effect, the encapsulation works like an insect caught in amber. Solids, gasses, and fluids are all trapped inside a sturdy hard capsule. Impurities are thus able to be left in place, with no hazard to crews that may have had to work in close proximity to remove them.
It is a good idea to choose a white, yellowish, or red colorization for the first cover, or “seal cover.” Subsequent topcoats are a contrasting color like gray or brown. In this way, workers moving around the contaminated surfaces 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 continue as solid as needed, and comes in colors as well as clear. When applying floor seals that may be 20 to 500 mils solid as they repair and level imperfect floor floors, it is critical to consider the level of the covering in addition to the length and width issues of normal roll-on applications. When drinking water is poured on wine glass, it protrudes above the surface at the edges. Tugging a finger although water, one views flattening at the admittance and exit details due to its surface tension. When leveling surfaces, these same effects of the epoxy’s surface tension must be dealt with. Quite simply “self-levelling,” which is incomplete even for fluids like water, will not produce a flat top coating of epoxy.
100% epoxy coatings do not reduce and will harden at any height it is kept at after being catalyzed. But special methods are needed in order to assure a set surface while filling up unequal anomalies in the substrate. Experience has driven that using a squeegee-like action with a very short nap roller (3/16″) creates a pool of epoxy that may be pulled towards you to leak into low places while keeping the surface flat. Care can be used to apply an even coat at the surface, and too much moving can cause the top to try to contour along the floor’s imperfections.
