Remediation of pollution can be costly and technically difficult. Many talk about and local air pollution control agencies have found that encapsulating contaminated concrete is the most cost-effective and long lasting solution for existing contamination. 100% solid epoxy can seal contaminants into the concrete with tiers of 10 to 100 mils dense. In effect, the encapsulation works like an insect caught in amber. Solids, gasses, and liquids are all caught inside a sturdy hard capsule. Impurities are thus able to be left set up, with no danger to crews that may have had to work in close proximity to remove them.
It is highly recommended to choose a white, yellowish, or red color for the first overcoat, or “seal overcoat.” Following topcoats are a contrasting color like grey or brown. In this manner, workers moving around 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 heavy as needed, and will come in colors as well as clear. When making use of floor seals that may be 20 to 500 mils heavy as they repair and level imperfect floor floors, it is advisable to consider the level of the finish in addition to the length and width issues of normal roll-on applications. When normal water is poured on goblet, it protrudes above the surface at the corners. Pulling a finger although water, one sees flattening at the access and exit details because of its surface tension. When leveling floors, these same ramifications of the epoxy’s surface stress must be dealt with. In other words “self-levelling,” which is imperfect even for fluids like water, will not produce a smooth top layer of epoxy.
100% epoxy coatings do not reduce and can harden at any level it is still left at after being catalyzed. But special techniques are needed to be able to assure a flat surface while filling uneven anomalies in the substrate. Experience has driven 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 leak into low places while keeping the surface flat. Care can be used to apply an even coat at the surface, and too much rolling can cause the surface to try to contour over the floor’s imperfections.
