Remediation of pollution can be expensive and theoretically difficult. Many express and local pollution control organizations have found that encapsulating contaminated concrete is the most inexpensive and long lasting solution for existing contamination. 100% sound epoxy can seal pollutants into the concrete with layers of 10 to 100 mils dense. In effect, the encapsulation works like an insect captured in amber. Solids, gasses, and fluids are all captured inside a stable hard capsule. Impurities are thus in a position to be left in place, with no threat to crews that may have had to work near remove them.
It is advisable to choose a white, yellow, or red color for the first coating, or “seal overcoat.” Following topcoats are a contrasting color like gray or brown. In this manner, workers moving around the contaminated areas are alerted when wear has made re-coating necessary. The contrasting colors thus provide a “wear meter.”
100% epoxy has no odor, can continue as dense as needed, and will come in colors as well as clear. When applying floor seals that can be 20 to 500 mils heavy as they repair and level imperfect floor areas, it is critical to consider the elevation of the covering as well as the length and width issues of normal roll-on applications. When water is poured on goblet, it protrudes above the top at the corners. Pulling a finger though the water, one recognizes flattening at the access and exit details because of its surface stress. When leveling floors, these same effects of the epoxy’s surface anxiety must be handled. In other words “self-levelling,” which is imperfect even for liquids like water, won’t produce a smooth top covering of epoxy.
100% epoxy coatings do not shrink and can harden at any height it is kept at after being catalyzed. But special procedures are needed in order to assure a flat surface while filling up uneven anomalies in the substrate. Experience has established that by using a squeegee-like action with a very short nap roller (3/16″) creates a pool of epoxy that can be pulled towards you to drip into low areas while keeping the top flat. Care can be used to apply an even coat at the top, and too much moving can cause the top to attempt to contour over the floor’s imperfections.
