Remediation of pollution can be costly and technically difficult. Many state and local pollution control firms have found that encapsulating contaminated cement is the most economical and long lasting solution for existing contaminants. 100% solid epoxy can seal impurities into the cement with layers of 10 to 100 mils heavy. In effect, the encapsulation works as an insect stuck in amber. Solids, gasses, and fluids are all stuck inside a sound hard capsule. Contaminants are thus able to be left set up, with no threat 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 coating, or “seal coat.” Following topcoats are a contrasting color like grey or brown. In this manner, workers moving around the contaminated surfaces are alerted when wear has made re-coating necessary. The contrasting colors thus give a “wear meter.”
100% epoxy has no odor, can go on as thick as needed, and comes 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 coating as well as the length and width issues of normal roll-on applications. When water is poured on cup, it protrudes above the top at the edges. Tugging a finger although water, one sees flattening at the accessibility and exit tips because of its surface tension. When leveling floors, these same effects of the epoxy’s surface stress must be handled. In other words “self-levelling,” which is imperfect even for fluids like water, won’t produce a flat top covering of epoxy.
100% epoxy coatings do not reduce and will harden at any height it is still left at after being catalyzed. But special methods are needed in order to assure a flat surface while filling uneven anomalies in the substrate. Experience has determined that utilizing a squeegee-like movement with an extremely 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 must be used to apply an even coat at the top, and too much rolling can cause the surface to attempt to contour across the floor’s imperfections.
