Remediation of air pollution can be expensive and officially difficult. Many state and local air pollution control agencies have found that encapsulating contaminated cement is the most inexpensive and long lasting solution for existing contamination. 100% sturdy epoxy can seal impurities into the concrete with tiers of 10 to 100 mils thick. In effect, the encapsulation works like an insect caught in amber. Solids, gasses, and liquids are all stuck inside a sturdy hard capsule. Contaminants 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 a good idea to choose a white, yellow, or red color for the first overcoat, or “seal coat.” Subsequent topcoats are a contrasting color like gray or brown. In this way, workers moving around the contaminated floors 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 comes in colors as well as clear. When making use of floor seals that can be 20 to 500 mils heavy as they repair and level imperfect floor surfaces, 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 cup, it protrudes above the surface at the ends. Pulling a finger though the water, one perceives flattening at the entrance and exit details because of its surface stress. When leveling floor surfaces, these same effects of the epoxy’s surface anxiety must be handled. Quite simply “self-levelling,” which is imperfect even for fluids like water, won’t produce a toned top coating of epoxy.
100% epoxy coatings do not shrink and will harden at any elevation it is kept at after being catalyzed. But special methods are needed in order to assure a set surface while filling up uneven anomalies in the substrate. Experience has determined that by using a squeegee-like movement with a very short nap roller (3/16″) creates a pool of epoxy that may be pulled in your direction to leak into low areas while keeping the top flat. Care must be used to apply an even coat at the surface, and too much rolling can cause the surface to try to contour along the floor’s imperfections.
