Now Encapsulate Contaminated Materials to Remedy Pollution
Problems.
Remediation of pollution can be expensive and technically
difficult. Now many state and local pollution control agencies
have found that encapsulating contaminated concrete is the most
economical and long lasting solution for existing contamination.
100% solid epoxy can seal contaminants into the concrete with
layers of 10 to 100 mils thick. In effect, the encapsulation
works like an insect trapped in amber. Solids, gasses, and
liquids are all trapped inside a solid hard capsule.
Contaminants can thus be left in place, with no danger 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 coat, or "seal coat." Subsequent topcoats are a
contrasting color like gray or brown. In this way, workers
moving around the contaminated surfaces 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 thick as needed, and comes
in colors as well as clear. When applying floor seals that can
be 20 to 500 mils thick as they repair and level imperfect floor
surfaces, it is critical to consider the height of the coating
in addition to 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
sees flattening at the entry and exit points due to its surface
tension. When leveling floors, these same effects of the epoxy's
surface tension must be dealt with. In other words
"self-leveling," which is incomplete even for liquids like
water, will not produce a flat top layer of epoxy.
100% epoxy coatings do not shrink and will harden at any height
it is left at after being catalyzed. But special procedures are
needed in order to assure a flat surface while filling uneven
anomalies in the substrate. Experience has determined that using
a squeegee-like motion with a very short nap roller (3/16")
creates a pool of epoxy that can be pulled towards you to leak
into low spots while keeping the surface flat. Care must be used
to apply an even coat at the surface, and too much rolling can
cause the surface to try to contour along the floor's
imperfections.
