Contaminated concrete can be Modified by Encapsulating on Epoxy binder

Remediation of air pollution can be costly and theoretically difficult. Many condition and local air pollution control agencies have found that encapsulating contaminated concrete is the most inexpensive and long lasting solution for existing contamination. 100% stable epoxy can seal impurities into the cement with levels of 10 to 100 mils dense. In place, the encapsulation works as an insect captured in amber. Solids, gasses, and fluids are all captured inside a sturdy hard capsule. Impurities are thus able to be left in place, with no danger to crews that may have had to work in close proximity to remove them.
It is highly recommended to choose a white, yellowish, or red color for the first layer, or “seal layer.” Following topcoats are a contrasting color like grey or brown. In this manner, workers active the contaminated areas 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 go on as thick as needed, and will come in colors as well as clear. When applying floor seals that may be 20 to 500 mils dense as they repair and level imperfect floor areas, it is advisable to consider the level of the covering as well as the length and width issues of normal roll-on applications. When water is poured on glass, it protrudes above the surface at the edges. Pulling a finger though the water, one recognizes flattening at the entrance and exit details because of its surface pressure. When leveling 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, will not produce a chiseled top layer of epoxy.

100% epoxy coatings do not shrink and will harden at any level it is kept at after being catalyzed. But special steps are needed to be able to assure a set surface while filling uneven anomalies in the substrate. Experience has motivated that using a squeegee-like movement with an extremely short nap roller (3/16″) creates a pool of epoxy that can be pulled towards you to drip into low spots while keeping the top flat. Care can be used to apply an even coat at the top, and too much rolling can cause the top to try to contour over the floor’s imperfections.
