Remediation of air pollution can be costly and technically difficult. Many condition and local pollution control firms have found that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contamination. 100% sturdy epoxy can seal contaminants into the cement with levels of 10 to 100 mils thick. In place, the encapsulation works as an insect trapped in amber. Solids, gasses, and liquids are all trapped inside a stable hard capsule. Pollutants are thus in a position to be left in place, with no danger to crews that might experienced to work near remove them.
It is a good idea to choose a white, yellow, or red colorization for the first cover, or “seal layer.” Succeeding 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 provide a “wear meter.”
100% epoxy does not have any odor, can go on as dense as needed, and comes in colors as well as clear. When making use of floor seals that can be 20 to 500 mils thick as they repair and level imperfect floor areas, it is advisable to consider the height of the layer in addition to the length issues of normal roll-on applications. When water is poured on glass, it protrudes above the surface at the sides. Pulling a finger although water, one considers flattening at the entry and exit details due to its surface stress. When leveling surfaces, these same effects of the epoxy’s surface pressure must be handled. In other words “self-levelling,” which is incomplete even for liquids like water, will not produce a level top coating of epoxy.
100% epoxy coatings do not shrink and will harden at any elevation it is remaining at after being catalyzed. But special strategies are needed in order to assure a flat surface while filling up unequal anomalies in the substrate. Experience has identified that by using a squeegee-like movement with an extremely short nap roller (3/16″) creates a pool of epoxy that may 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 top, and too much moving can cause the top to attempt to contour along the floor’s imperfections.
