Remediation of air pollution can be costly and officially difficult. Many condition and local pollution control companies have found that encapsulating contaminated cement is the most cost-effective and long lasting solution for existing contamination. 100% sound epoxy can seal impurities into the cement with layers of 10 to 100 mils thick. In effect, the encapsulation works as an insect trapped in amber. Solids, gasses, and fluids are all trapped inside a stable hard capsule. Contaminants are thus in a position to be left in place, with no hazard to crews that might experienced to work in close proximity to remove them.
It is highly recommended to choose a white, yellow, or red colorization 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 heavy 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 surfaces, it is advisable to consider the elevation of the layer as well as the length and width issues of normal roll-on applications. When water is poured on cup, it protrudes above the top at the corners. Pulling a finger though the water, one views flattening at the access and exit things due to its surface anxiety. When leveling surfaces, these same effects of the epoxy’s surface tension must be dealt with. In other words “self-levelling,” which is imperfect even for liquids like water, won’t produce a flat top covering of epoxy.
100% epoxy coatings do not reduce and will harden at any level it is still left at after being catalyzed. But special techniques are needed in order to assure a flat surface while filling uneven anomalies in the substrate. Experience has identified that using a squeegee-like movement with an extremely short nap roller (3/16″) creates a pool of epoxy that may be pulled towards you to leak into low spots while keeping the top flat. Care must be used to apply an even coat at the top, and too much moving can cause the surface to try to contour along the floor’s imperfections.
