Remediation of pollution can be costly and officially difficult. Many status and local pollution control businesses have found that encapsulating contaminated concrete is the most economical and long lasting solution for existing contaminants. 100% sound epoxy can seal contaminants into the concrete with tiers of 10 to 100 mils solid. In effect, the encapsulation works as an insect caught in amber. Solids, gasses, and fluids are all trapped inside a solid hard capsule. Pollutants are thus able to be left set up, with no danger to crews that might 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 layer, or “seal overcoat.” Subsequent topcoats are a contrasting color like grey or brown. In this manner, workers moving around the contaminated floors 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 will come in colors as well as clear. When making use of floor seals that can be 20 to 500 mils solid as they repair and level imperfect floor surfaces, it is critical to consider the level of the finish in addition to the length issues of normal roll-on applications. When drinking water is poured on a glass, it protrudes above the top at the sides. Pulling a finger though the water, one considers flattening at the entrance and exit tips due to its surface tension. When leveling flooring surfaces, these same effects 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 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 decided that by using a squeegee-like movement 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 must be used to apply a straight coat at the top, and too much moving can cause the surface to try to contour across the floor’s imperfections.
