Remediation of air pollution can be costly and technically difficult. Many state and local pollution control companies have discovered that encapsulating contaminated concrete is the most inexpensive and long lasting solution for existing contaminants. 100% sound epoxy can seal contaminants into the cement with levels of 10 to 100 mils heavy. In effect, the encapsulation works like an insect trapped in amber. Solids, gasses, and fluids are all trapped inside a stable hard capsule. Contaminants are thus in a position to be left in place, with no threat to crews that might have had to work near remove them.
It is a good idea to choose a white, yellow, or red color for the first cover, or “seal coat.” Subsequent topcoats are a contrasting color like gray or brown. In this way, workers active the contaminated surfaces 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 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 heavy as they repair and level imperfect floor floors, it is advisable to consider the level of the finish as well as the length issues of normal roll-on applications. When water is poured on cup, it protrudes above the top at the corners. Pulling a finger though the water, one views flattening at the accessibility and exit factors due to its surface pressure. When leveling flooring, these same effects of the epoxy’s surface pressure must be handled. In other words “self-levelling,” which is imperfect even for liquids like water, will not produce a level top layer of epoxy.
100% epoxy coatings do not shrink and can harden at any elevation it is kept at after being catalyzed. But special techniques are needed in order to assure a set surface while filling unequal anomalies in the substrate. Experience has decided that utilizing a squeegee-like motion with a very short nap roller (3/16″) creates a pool of epoxy that can be pulled towards you to drip into low places 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 try to contour across the floor’s imperfections.
