Remediation of air pollution can be expensive and theoretically difficult. Many talk about and local pollution control firms have discovered that encapsulating contaminated concrete is the most economical and long lasting solution for existing contaminants. 100% stable epoxy can seal contaminants into the concrete with levels of 10 to 100 mils thick. In place, the encapsulation works like an insect stuck in amber. Solids, gasses, and liquids are all caught inside a sturdy hard capsule. Pollutants are thus able to be left set up, with no risk to crews that might have had to work near remove them.
It is advisable to choose a white, yellowish, or red color for the first layer, or “seal coat.” Succeeding topcoats are a contrasting color like grey or brown. In this manner, 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 heavy as needed, and will come 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 critical to consider the elevation of the covering as well as the length issues of normal roll-on applications. When normal water is poured on wine glass, it protrudes above the top at the edges. Pulling a finger although water, one perceives flattening at the access and exit items because of its surface stress. When leveling flooring surfaces, these same ramifications of the epoxy’s surface tension must be dealt with. In other words “self-levelling,” which is imperfect even for fluids like water, won’t produce a toned top level of epoxy.
100% epoxy coatings do not reduce and can harden at any level it is still left at after being catalyzed. But special procedures are needed in order to assure a flat surface while filling unequal anomalies in the substrate. Experience has decided that using a squeegee-like action with an extremely short nap roller (3/16″) creates a pool of epoxy that may be pulled in your direction to leak into low spots while keeping the surface flat. Care can be used to apply a straight coat at the surface, and too much moving can cause the surface to try to contour over the floor’s imperfections.
