Remediation of pollution can be expensive and theoretically difficult. Many state and local pollution control agencies have found that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contamination. 100% stable epoxy can seal contaminants into the cement with levels of 10 to 100 mils dense. In place, the encapsulation works like an insect caught in amber. Solids, gasses, and fluids are all caught inside a stable hard capsule. Contaminants are thus in a position 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 color for the first overcoat, or “seal cover.” Following topcoats are a contrasting color like grey 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 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 heavy as they repair and level imperfect floor floors, it is advisable to consider the height of the finish in addition to the length and width issues of normal roll-on applications. When normal water is poured on wine glass, it protrudes above the surface at the corners. Tugging a finger although water, one considers flattening at the access and exit things due to its surface tension. When leveling flooring, these same ramifications of the epoxy’s surface anxiety must be dealt with. Quite simply “self-levelling,” which is imperfect even for liquids like water, will not produce a smooth top level of epoxy.
100% epoxy coatings do not shrink and will harden at any height it is left at after being catalyzed. But special techniques are needed to be able to assure a flat surface while filling unequal anomalies in the substrate. Experience has identified that using a squeegee-like action with an extremely short nap roller (3/16″) creates a pool of epoxy that may be pulled in your direction to leak into low locations while keeping the top flat. Care must be used to apply a straight coat at the top, and too much rolling can cause the top to try to contour over the floor’s imperfections.
