Remediation of pollution can be costly and technically difficult. Many condition and local pollution control organizations have found that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contaminants. 100% sound epoxy can seal pollutants into the cement with layers of 10 to 100 mils heavy. In effect, the encapsulation works like an insect captured in amber. Solids, gasses, and liquids 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 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.” Subsequent topcoats are a contrasting color like grey or brown. In this way, 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 go on as solid as needed, and comes in colors as well as clear. When applying floor seals that can be 20 to 500 mils dense as they repair and level imperfect floor surfaces, it is advisable to consider the level of the covering as well as the length issues of normal roll-on applications. When water is poured on cup, it protrudes above the top at the corners. Tugging a finger though the water, one views flattening at the entrance and exit details due to its surface anxiety. When leveling surfaces, these same effects of the epoxy’s surface stress must be dealt with. Quite simply “self-levelling,” which is imperfect even for liquids like water, will not produce a flat top level of epoxy.
100% epoxy coatings do not reduce and will harden at any height it is still left at after being catalyzed. But special methods are needed to be able to assure a flat surface while filling up uneven anomalies in the substrate. Experience has driven that by using a squeegee-like action with an extremely brief nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to drip into low locations while keeping the surface flat. Care must be used to apply a straight coat at the surface, and too much rolling can cause the top to try to contour along the floor’s imperfections.
