Remediation of pollution can be expensive and technically difficult. Many state and local air pollution control companies have found that encapsulating contaminated concrete is the most economical and long lasting solution for existing contaminants. 100% stable epoxy can seal contaminants into the concrete with layers of 10 to 100 mils solid. In effect, the encapsulation works like an insect caught in amber. Solids, gasses, and liquids are all captured inside a sturdy hard capsule. Pollutants are thus able to be left set up, with no risk to crews that might have had to work in close proximity to remove them.
It is advisable to choose a white, yellow, or red colorization for the first coating, or “seal cover.” Succeeding topcoats are a contrasting color like gray or brown. In this manner, workers moving around the contaminated surfaces 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 heavy as needed, and will come in colors as well as clear. When making use of 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 covering as well as the length issues of normal roll-on applications. When normal water is poured on wine glass, it protrudes above the top at the edges. Pulling a finger though the water, one recognizes flattening at the access and exit factors due to its surface pressure. When leveling surfaces, these same ramifications of the epoxy’s surface stress must be handled. In other words “self-levelling,” which is imperfect even for liquids like water, won’t produce a chiseled top covering of epoxy.
100% epoxy coatings do not reduce and can harden at any elevation it is kept at after being catalyzed. But special steps are needed in order to assure a flat surface while filling unequal anomalies in the substrate. Experience has determined that using a squeegee-like action with an extremely short nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to drip into low spots while keeping the surface flat. Care can be used to apply a straight coat at the top, and too much moving can cause the surface to try to contour along the floor’s imperfections.
