Remediation of pollution can be costly and officially difficult. Many status and local pollution control companies have found that encapsulating contaminated concrete is the most inexpensive and long lasting solution for existing contamination. 100% sturdy epoxy can seal contaminants into the concrete with levels of 10 to 100 mils thick. In place, the encapsulation works as an insect stuck in amber. Solids, gasses, and liquids are all trapped inside a sound hard capsule. Pollutants are thus able to be left set up, with no risk to crews that may have had to work in close proximity to remove them.
It is recommended to choose a white, yellowish, or red color for the first coating, or “seal layer.” Subsequent topcoats are a contrasting color like grey or brown. In this manner, workers moving around the contaminated areas are alerted when wear has made re-coating necessary. The contrasting colors thus provide a “wear meter.”
100% epoxy has no odor, can go on as heavy as needed, and will come in colors as well as clear. When making use of floor seals that can be 20 to 500 mils dense as they repair and level imperfect floor surfaces, it is advisable to consider the elevation of the layer in addition to the length and width issues of normal roll-on applications. When water is poured on cup, it protrudes above the surface at the sides. Pulling a finger though the water, one recognizes flattening at the access and exit points because of its surface stress. When leveling floor surfaces, these same effects of the epoxy’s surface tension must be dealt with. In other words “self-levelling,” which is imperfect even for liquids like water, won’t produce a even top layer of epoxy.
100% epoxy coatings do not shrink and will harden at any height it is remaining at after being catalyzed. But special types of procedures are needed in order to assure a set surface while filling uneven anomalies in the substrate. Experience has decided that using 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 locations while keeping the top flat. Care must be used to apply an even coat at the surface, and too much rolling can cause the top to attempt to contour across the floor’s imperfections.
