We recommend using the Elastameric
Variable Membrane (EVM) Copolymer Coatings (roll-on/spray-on
interior finishes) with our insulated pool wall system. Many
types of interior finishes can be used, such as: Composite Fiberglass
Finish (CFF), Epoxy Coatings, and Pre-fabricated Liners (only
available for purchase from other manufacturers), however we
only provide the EVM Coatings with our pool kits.
Each manufacturer warranties their interior
product anywhere from 5 to 25 years.
Elastomeric Variable Membrane (EVM) Copolymer
Coatings were developed to overcome one of the inherent deficiencies
in conventional surface coatings -- that is to provide film
continuity in the event of an existing or developing cracks
in a masonry surface. EVM coatings completely seal surface porosity
and cracks. That means leak proof!

Membrane (EVM) Pool Coating
Our 30 years
of experience indicates that EVM coatings can be applied by
spray-on or roll-on to virtually any dry, clean porous substrate
and clean, hard surfaces. This includes concrete, masonry,
stucco, plasters, sheetrock, stainless steel, steel, fiberglass
Proper application over the proper
primer insures an adhesion of 20 pounds per square inch and
this level assures protection from blistering or de-lamination
except in applications, which require vapor transmission through
In this application, a sealer/primer – Hydrostop
3000 – is rolled on the surface (pools, water tanks, etc.) to
seal pores and stop hydro static pressure and vapor transmission.
The EVM coating has a tensile strength of 1500 psi and elongates
in excess of two hundred percent at 70°F and remains flexible
at temperatures as low as -30°F. The ability to elongate
normally compensates for most structural movement and eliminates
the hairline cracks that develop with non-elastic coatings.
Pools and roofs have gone 10 years and more without discoloration.
We have the records. If desired, the coating may be rejuvenated
at anytime by repeating the cleaning and top coat application.
Our product has made pools and roofs watertight for over 30
years. It makes any pool structure even more effective
and durable. This product comes in white, but can be ordered
in any color when a color sample is provided and for $0.25 per
With this type of pool finish, you'll reduce
your pool maintenance, and there can be a noticeable reduction
in pool chemical requirements and energy usage, thus helping
The finish is easily cleaned with simple
detergents. EVM coatings will not allow mildew or mold
to grow and is unmarred by most acids, alkalis, solvents, oils
and even sea water. Our coatings have been health approved by
state department officials. This product has been used on new
pools and remodels by residential customers to commercial projects
including for the U.S. military.
