Remediation of air pollution can be expensive and technically difficult. Many state and local pollution control agencies have discovered that encapsulating contaminated concrete is the most cost-effective and resilient solution for existing contaminants. 100% solid epoxy can seal impurities into the cement with levels of 10 to 100 mils heavy. In place, the encapsulation works as an insect stuck in amber. Solids, gasses, and liquids are all captured inside a stable hard capsule. Pollutants are thus in a position to be left in place, with no threat to crews that may experienced to work in close proximity to remove them.
It is recommended to choose a white, yellowish, or red colorization for the first layer, or “seal coat.” Subsequent topcoats are a contrasting color like grey or brown. In this way, workers active 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 comes 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 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 a glass, it protrudes above the top at the edges. Pulling a finger although water, one recognizes flattening at the admittance and exit details due to its surface tension. When leveling floor surfaces, these same ramifications 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 level top coating of epoxy.
100% epoxy coatings do not reduce and will harden at any elevation it is still left at after being catalyzed. But special types of procedures are needed to be able to assure a flat surface while filling uneven anomalies in the substrate. Experience has identified that by using a squeegee-like action 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 surface 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.
