If your pool
needs to be refinished or repaired or you
want to lessen the cost to operate your
pool, you can now do both by utilizing the
insulated wall panel system and
EVM Coating
(Elastameric Variable Membrane).
Suppose
that you have a concrete (Gunite) plastered pool
and that pool conducts 1.7 w/m-k... to
understand this in a more familiar term it is
represented as an R factor (insulation factor).
8" of concrete or Gunite would have an R factor
of R-0.68. Any metal wall, acrylic wall or
fiberglass pool would have a similar R factor,
less than 3/4 of 1% (single paned windows are
better). During the summer, the average ground
temperature across the United States is less
than 60 degrees, the farther north you are the
colder it is; for example: in Sacramento, CA,
the ground temperature is 56 degrees in the
summer. If you have an 18"x36" pool with
approximately 1,200 sq. ft. of pool surface in
contact with a ground temperature of 60 degrees
maximum and you want the pool water to be 85
degrees, you would need to produce 360,000 BTU
of heat per day to keep the water 85 degrees.
That's 3 times the surface loss of heat you
would lose to the air, which can be reduced or
almost eliminated with the installation of a
solar blanket pool cover. If you installed our
2" insulated wall panel system over the concrete
(Gunite) pool structure it would reduce the heat
loss from the ground to 50,000 BTU, which is 14%
of the original heat requirement of 360,000 BTU,
and would result in an 86% energy savings in
heating costs. If you used our 1" panel, your
savings would be half of the 2" insulation.
We offer an insulated pool panel system to
retrofit and renovate any type of pool structure
whether it's a Gunite/plastered pool, metal
wall, acrylic wall or fiberglass pool structure
(pools must have 3-1/2" concrete floor). This
product comes in two thicknesses, 1" with an R-5
factor or 2" with an R-10 factor. The panels are
attached to the entire interior wall surface of
the pool utilizing Ener-bonder adhesive by Dow
or lock-tight adhesive by Permatex or any other
styrofoam adhesive. Any voids, cracks or seams
should be filled with expanding polystyrene foam
after installing panels. This expanding
polystyrene foam comes in a spray can and can be
purchased from any building supply store. The
insulation foam panel then needs to be roughed
up (with a stiff wire brush) and coated with a
polymer or acrylic bonder such as Acryl 60 or
similar. A thin coat of structural plaster 1/4"
thick is then applied to the entire insulated
pool surface. When we ship the insulation
product to you, we also ship a polystyrene mesh,
which is troweled into the first coat of
structural plaster. A second coat of 1/4"
structural plaster is applied over the first
coat embedding the mesh between both coats; the
second coat is a finish coat and must be applied
as smooth as possible. The plaster should be
mist-sprayed for 3-5 days during the wet/dry
curing process.
The inlets coming into the pool need to be
extended out by the thickness of the foam that
you are installing over your existing pool
surface. The light niche does not have to be
extended nor does the skimmer. This is because
the EVM Coating will wrap around and end within
both of the light niche and skimmer. Any screw
holes in any of the above items need to be
marked by installing a toothpick in the screw
hole so it can be located after the coating has
been applied. When re-applying any screws, the
hole should be filled with silicone sealant and
silicone should be applied to the screw to
prevent any possibility of water leaks. If your
pool is equipped with a main drain, the main
drain will need to be extended and modified to
meet the new Federal Law, Virginia Graeme Baker
Act, which went into effect December 19, 2008.
This means all pool drains have to be updated
with an anti-entrapment type, approved VGB
cover.
At this point you are ready to install the EVM
Coating (Elastameric Variable Membrane) interior
pool finish. The EVM Coating comes in white, but
can be ordered in different colors for an
additional $0.25 cents per sq. ft. and by
submitting a color chip. You can use either an
adhesive tile or real pool tile with the EVM
Coating. We offer a Borderline vinyl adhesive
tile in two sizes and three different patterns
for each size; a 6" tile for $2.50 a Lineal Ft.
or a 9" for $3.75 a Lineal Ft. The Borderline
tile will last approximately 3 or 4 years and
can easily be replaced. You can use real pool
tile with silicone sealant and silicone grout.
If you are using real pool tile it will last
indefinitely, but it would adds 3/8" that would
make the total thickness of 1-7/8" at the top of
the wall under the coping. If you are using
Borderline tile, you are only adding 1-5/8"
total thickness at the top.
If you are going to insulate the pool with the
2" polystyrene foam insulation you will have to
extend the coping out a minimum of 2-1/2" unless
you are applying real tile then the coping would
need to be extended 2-7/8". The price for the 1"
R-5 insulating panel with the polystyrene mesh
and the EVM Coating (in white) including
delivery is $5.50 per sq. ft. The price for the
2" R-10 insulating panel with the polystyrene
mesh and the EVM Coating (in white) including
delivery is $7.50 per sq. ft.
Benefits you will
receive:
•Naturally
warmer pool, increase pool season approximately
2 months, depending on your location
•Heating costs will be dramatically reduced,
saving energy costs in gas or electric heating
will be cut even if you are using solar heating
because you won't have to run the solar system
as long
•A completely new looking pool with a fresh
interior coating that is warranted for 20 years
the longevity of your pool will be dramatically
increased
•Comes in any color
•Less chemical usage, easily cleaned with simple
detergents
•Will not support algae
•Consistently smooth, no scuffed feet or knees
•Elasticity of 200% stretch even though bonded
to the structure, tensile strength of 1,500 psi
•Remains flexible at temperatures as low as 30
degrees F
•Watertight, impervious membrane
•Resistant to many common chemicals
•EVM Coating has been approved by state health
department officials
The use of these products reduces total energy
use and fossil fuel emission and improves energy
efficiency nationwide. Additionally, this
technology focuses on low capital improvements
with immediate return.
You might also want to change your pool pump by
switching from a single speed pump to a
two-speed pump of similar size to conserve
energy as this will save two-thirds of your pump
energy cost.
In order to provide you with the appropriate
insulating panels, you will need to supply us
with a 1/4" scaled drawing showing us the entire
shape, depth and curvature of the pool bottom so
that we can calculate the proper amount of
material for your particular pool size, shape,
etc. Shipping time is 10-14 days.
EVM
Coating - Application Procedure
For Pools with Steel and
acrylic side walls and concrete bottoms
1. Use a width of our polystyrene mesh (2” or
3”) to cover the panel joint where the panel
meets the floor, use the Hydro-Stop Sealer 3000
to attach strips. Follow the rest of the steps
below. Each application can proceed as soon as
the previous application is dry to the touch.
For Concrete or Fiberglass Pools
2. Roll-on Hydro Stop 3000 over the plastered
walls and concrete bottom and let set 2 hours,
or until dry. Note: All square corners need to
have the coatings applied with a large paint
brush before the normal spray application. Watch
for white blush. Rinse with water to remove
blush.
3. Spray-on or roll-on Primer 2836 on walls.
4. Spray three double passes Finish Coat 2850 on
floor and walls. ↕ ↔ ↕
Note: If any imperfections are seen or
noticeable after the spray application, you
should go back over these areas again with a
roller.
You should get 30 to 40 sq. ft. per gallon from
the EVM Coating.
Remember
-- you can’t hurt it if you put on too much –
only if you don’t put enough on!
NOTE: Sometimes the EVM Middle-coat is like
Jell-O.
Mixing at high rate will reduce viscosity to a
cream consistency.
