Remediation of air pollution can be costly and technically difficult. Many status and local air pollution control businesses have discovered that encapsulating contaminated concrete is the most inexpensive and resilient solution for existing contamination. 100% sturdy epoxy can seal contaminants into the concrete with tiers of 10 to 100 mils heavy. In effect, the encapsulation works as an insect captured in amber. Solids, gasses, and liquids are all stuck inside a sturdy hard capsule. Pollutants are thus able to be left in place, with no danger to crews that might have had to work near remove them.
It is a good idea to choose a white, yellow, or red color for the first cover, or “seal overcoat.” Subsequent 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 heavy as needed, and comes in colors as well as clear. When applying floor seals that may be 20 to 500 mils dense as they repair and level imperfect floor areas, it is critical to consider the elevation of the finish in addition to the length issues of normal roll-on applications. When water is poured on a glass, it protrudes above the surface at the sides. Pulling a finger although water, one sees flattening at the entrance and exit points because of its surface pressure. When leveling flooring surfaces, these same ramifications of the epoxy’s surface stress must be dealt with. Quite simply “self-levelling,” which is incomplete even for fluids like water, won’t produce a flat top coating of epoxy.
100% epoxy coatings do not shrink and will harden at any level it is kept at after being catalyzed. But special steps are needed in order to assure a set surface while filling up uneven anomalies in the substrate. Experience has identified that by using a squeegee-like motion with an extremely short nap roller (3/16″) creates a pool of epoxy that can be pulled towards you to leak into low locations while keeping the surface flat. Care can be used to apply an even coat at the surface, and too much moving can cause the top to try to contour across the floor’s imperfections.
