Remediation of pollution can be costly and theoretically difficult. Many express and local air pollution control organizations have found that encapsulating contaminated cement is the most economical and resilient solution for existing contaminants. 100% sturdy epoxy can seal impurities into the cement with tiers of 10 to 100 mils heavy. In effect, the encapsulation works like an insect captured in amber. Solids, gasses, and fluids are all trapped inside a solid hard capsule. Pollutants are thus able to be left set up, with no threat to crews that might have had to work near remove them.
It is a good idea to choose a white, yellow, or red colorization for the first layer, or “seal overcoat.” Subsequent topcoats are a contrasting color like gray 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 has no odor, can continue as dense as needed, and will come in colors as well as clear. When applying floor seals that may be 20 to 500 mils heavy as they repair and level imperfect floor areas, it is advisable to consider the elevation of the coating in addition to the length and width issues of normal roll-on applications. When drinking water is poured on cup, it protrudes above the surface at the edges. Tugging a finger though the water, one perceives flattening at the access and exit items due to its surface anxiety. When leveling floor surfaces, these same effects of the epoxy’s surface tension must be handled. Quite simply “self-levelling,” which is imperfect even for fluids like water, will not produce a level top level of epoxy.
100% epoxy coatings do not reduce and can harden at any elevation it is remaining at after being catalyzed. But special procedures are needed in order to assure a set surface while filling uneven anomalies in the substrate. Experience has determined that utilizing a squeegee-like movement with a very brief nap roller (3/16″) creates a pool of epoxy that can be pulled in your direction to leak into low areas while keeping the top flat. Care can be used to apply an even coat at the surface, and too much rolling can cause the top to attempt to contour along the floor’s imperfections.
