Remediation of air pollution can be expensive and theoretically difficult. Many condition and local air pollution control firms have discovered that encapsulating contaminated cement is the most inexpensive and resilient solution for existing contamination. 100% stable epoxy can seal contaminants into the cement with layers of 10 to 100 mils thick. In place, the encapsulation works like an insect captured in amber. Solids, gasses, and fluids are all captured inside a stable hard capsule. Impurities 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 color for the first layer, or “seal overcoat.” Following 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 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 critical to consider the height of the covering in addition to the length issues of normal roll-on applications. When water is poured on a glass, it protrudes above the top at the ends. Tugging a finger although water, one considers flattening at the entrance and exit points due to its surface tension. When leveling surfaces, these same ramifications of the epoxy’s surface tension must be dealt with. Quite simply “self-levelling,” which is imperfect even for liquids like water, won’t produce a flat top covering of epoxy.
100% epoxy coatings do not reduce and can harden at any height it is kept at after being catalyzed. But special techniques are needed to be able to assure a set surface while filling up unequal anomalies in the substrate. Experience has motivated that using a squeegee-like movement with an extremely brief 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 a straight coat at the surface, and too much moving can cause the top to try to contour across the floor’s imperfections.
