Remediation of air pollution can be expensive and theoretically difficult. Many state and local air pollution control agencies have found that encapsulating contaminated concrete is the most inexpensive and long lasting solution for existing contamination. 100% sturdy epoxy can seal pollutants into the concrete with layers of 10 to 100 mils solid. In effect, the encapsulation works like an insect captured in amber. Solids, gasses, and liquids are all trapped inside a sturdy hard capsule. Pollutants are thus in a position to be left in place, with no hazard to crews that may have had to work near remove them.
It is recommended to choose a white, yellowish, or red color for the first cover, or “seal layer.” Following topcoats are a contrasting color like gray or brown. In this manner, workers active 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 continue as heavy as needed, and comes 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 finish as well as the length and width issues of normal roll-on applications. When drinking water is poured on goblet, it protrudes above the surface at the edges. Pulling a finger although water, one considers flattening at the accessibility and exit items due to its surface stress. When leveling surfaces, these same ramifications of the epoxy’s surface anxiety must be dealt with. In other words “self-levelling,” which is imperfect even for fluids like water, will not produce a level top coating of epoxy.
100% epoxy coatings do not reduce and can harden at any height it is remaining at after being catalyzed. But special methods are needed in order to assure a set surface while filling unequal anomalies in the substrate. Experience has driven 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 drip into low spots while keeping the top flat. Care can be used to apply a straight coat at the top, and too much rolling can cause the surface to attempt to contour across the floor’s imperfections.
