Remediation of pollution can be costly and officially difficult. Many state and local pollution control organizations have found that encapsulating contaminated concrete is the most cost-effective and long lasting solution for existing contamination. 100% sound epoxy can seal contaminants into the concrete with layers of 10 to 100 mils thick. In effect, the encapsulation works as an insect caught in amber. Solids, gasses, and liquids are all stuck inside a sound hard capsule. Impurities are thus able to be left in place, with no risk to crews that might experienced to work near remove them.
It is advisable to choose a white, yellow, or red color for the first overcoat, or “seal coating.” Following topcoats are a contrasting color like gray or brown. In this way, workers active the contaminated areas are alerted when wear has made re-coating necessary. The contrasting colors thus give a “wear meter.”
100% epoxy has no odor, can continue as solid 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 surfaces, it is critical to consider the height of the coating as well as the length issues of normal roll-on applications. When water is poured on wine glass, it protrudes above the top at the sides. Tugging a finger although water, one recognizes flattening at the entry and exit points because of its surface anxiety. When leveling flooring, 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 toned top part of epoxy.
100% epoxy coatings do not shrink and will harden at any height it is kept at after being catalyzed. But special techniques are needed to be able to assure a set surface while filling up uneven anomalies in the substrate. Experience has established that by using a squeegee-like movement with a very short nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to drip into low places while keeping the top flat. Care can be used to apply an even coat at the surface, and too much moving can cause the surface to attempt to contour along the floor’s imperfections.
