Containment area coatings
avoid catastrophic contamination from chemical hazards, secondary containment
areas and sumps are often deployed. The finishes on these containment areas and
sumps must be durable enough to hold spills until they can be recovered or
neutralized and disposed of. Concrete is used as the base structural material in
most cases but it is porous, and many chemicals will soften or dissolve concrete
with prolonged exposure. To maintain integrity, concrete and most other
construction materials need to be coated with chemically resistant finishes.
These finishes must also be able repel moisture, withstand abrasion, and inhibit
rust and corrosion. Thus, only specialized, high chemically resistant finishes
for secondary containment areas are appropriate. Coatings must be able to stand
up to acids such as sulfuric or strong bleaches like chlorine, caustics like
potassium chloride, and various petroleum products like fuel oil.
Secondary containment area coatings are chemically resistant resin systems
applied in multiple coats to create an impermeable and contiguous shield over
the containment area construction materials. Normal application achieves a
thickness from 10-15 mils per coat. These finishes provide a great economical
approach to meeting the requirements of protecting concrete, wood, plastic, and
even asphalt construction materials. For this system to be truly effective, it
should be applied to a surface that is free from holes and other irregularities.
Appropriate detailing can customize the coating systems for handling a working
environment with normal wear and tear. Secondary containment area coatings are
formulated with added components that provide physical features suitable to most
industrial applications. Material selection must take into consideration the
capabilities of the coating or lining system to withstand the range of chemicals
that it will be exposed to along with handling the physical environmental
demands. Spill containment berms and sumps of any size for oil, fuel, and
chemical spills can be made by coating them with these cost-effective epoxy
coatings suitable for protecting concrete, plastic, steel, wood, and even
Common berm and containment applications include wash-down, storage, and
secondary containment for aircraft, trucks, tankers, trailers, and other
equipment in a variety of berm sizes, as well as containment of oil, fuel,
chemicals, acids, generators, trucks, and other power equipment used in-plant or
at remote locations.
These epoxy coating systems are generally applied in two or more coats,
resulting in a thickness of 20 mils to 40 mils. There is often the need for
support materials to bridge cracks and fill holes as required.
Durall offers complete kits custom
sized to each project and finish requirement. The kits include what is needed to
achieve a sufficiently smooth surface that will bind the coating well,
establishing the necessary impermeable and contiguous, chemically resistant
