Coating a swimming pool
with Dura-Bond is a three-step process:

A) Prepare the
swimming pool's surface
B) Prepare Dura-Bond for use
C) Application of Dura-Bond coating
A) Preparing
the swimming pool's surface:
The importance of properly
preparing the surface to be coated cannot be overemphasized. It is the
critical first step necessary to insure a beautiful, long-lasting finish.
- For pools previously painted
with either an epoxy or rubber base paint, it is first necessary to
pressure wash the surface at a minimum pressure of 3500 psi. A thorough
pressure wash should remove all loose or peeling material from the pool's
surface.
- Irregular surface areas
should be sanded to blend them into the surrounding area.
- If any bare spots are uncovered
during steps 1 and 2 above, they should be acid-etched with a solution
of at least I part acid to 3 parts water. When mixing this solution,
always add the acid to the water, never add the water to the acid. Be
sure to use a clean plastic bucket and never use a galvanized or other
metal container. When working with acid always use the proper safety
equipment including rubber gloves, slip- resistant boots and safety
goggles. A respirator is necessary unless adequate ventilation can be
provided. Avoid contact of the acid solution with the skin and eyes.
In the event of accidental skin or eye contact flush the exposed area
with water and, especially for eye contact, seek prompt medical attention.
- For plaster pools, the entire
surface must be acid- etched as in step 3 before proceeding. Brush the
acid solution on the plaster until the surface feels gritty and rough,
if after the first acid wash the surface is still smooth, repeat until
you have a rough surface.
- Following acid-etching,
the pool should be completely rinsed with water and any remaining acid
solution should be disposed of and/or neutralized according to local
regulations or environmental requirements.
- Next, the pool's surface
must be thoroughly cleaned. Scrub the walls and floor with either a
solution of water and tri-sodium phosphate (TSP) or a common household
cleanser such as Ajax. Rinse the surfaces completely with water removing
all traces of the cleaning agent.
- For previously painted or
older well-etched plaster pools no primer coat is required; proceed
to part B, Preparing Dura-Bond For Use. For relatively new or very smooth
plaster a primer coat is recommended to better penetrate the plaster.
- The most common failure
of painted pools is blistering or more commonly called, bubbles. This
is caused by moisture or water penetrating through the granite and plaster
from the exterior of the pool and getting behind the paint, causing
the paint to lift, creating blisters/bubbles. Delta Coatings has developed
a concrete sealer to stop the water from penetrating from the exterior.
DURA-SEAL is definitely recommended for first time painted pools. (See
Page 8)
- The second most common failure
is peeling, this is caused by the pool surface being too smooth and
not allowing the paint to get a good bond to the surface. In this situation,
we recommend the use of DURA-BOND PRIMER to better penetrate the smooth
plaster. In most cases the first coat of DURA-BOND can be applied the
same day as DURA-BOND PRIMER.
- To prep a FIBERGLASS pool,
sand the surface by hand or use a vibrator sander, always going in a
straight up and down direction. After sanding" wash pool with tri-sodium
or Ajax to clean or remove surface of all oils. Rinse good. No primer
is needed.
- For new or unpainted METAL
pools, wash with vinegar, this will remove any oils that may be in or
on the metal. No primer is needed. If pool previously painted, sand
and remove all loose paint, then wash as above.
B) Preparing
Dura-Bond for Use
-
Dura-Bond part A and Dura-Bond
part B must each be thoroughly mixed in their own factory one gallon
cans prior to use. Use separate wooden mixing sticks for this purpose,
) labeled " A " and "B " so that they are not interchanged. If a power
mixer is used, it should be only used on a slow setting. As with wooden
sticks, use separate paddles for part A and for part B. It is important
that no A and B are mixed together at this point.
- While not required, for
optimum results and to achieve the most consistent finish, DURA-BOND
should be "batched." This step can be especially important on the final
coat. Determine how much Dura-Bond will be required for each coat. Expect
an average coverage of about 300 ft. gal; less coverage for the first
coat and greater coverage for the second. Remember that coverage can
vary significantly depending on surface conditions; be sure there is
enough Dura-Bond on hand to do the entire job. Mix all of the Dura-Bond
part A you will need for the final coat in a large plastic bucket. Do
the same with Part B, being careful not to combine any A and B at this
point.
C) Application of Dura-Bond
Dura-Bond parts A and B should be mixed together in equal quantities five
minutes prior to use.
Once mixed, working time will
be approximately 30 to 45 minutes, depending on temperature. Higher temperatures
shorten the working time and lower temperatures lengthen it. Do not apply
Dura-Bond at temperatures below 50° F. For temperatures above 90°
F, place the A & B mixture on ice to lengthen the working time. Never
mix more Dura-Bond A & B together than can be applied in 30 to 45
minutes. Dura-Bond is an extremely bright finish; be sure to have good
quality sunglasses available to avoid the possibility of "snow blindness".
- Using a clean plastic bucket,
carefully mix equal parts of Dura-Bond part A and part B. Using a fresh
wooden stick labeled "mix", thoroughly combine A and B. If a power mixer
is used be careful to use a fresh paddle and a slow mixing speed. Remember
not to mix more Dura-Bond than can be applied in 30 to 45 minutes.
- Apply Dura-Bond to the pool's
previously prepared surface with a lamb's wool roller. For best results
use a roller with a phenolic core and a nap of no more than 318". Begin
coating the walls in the deep end, then the deep end floor, and work
up to the shallow end. Cover the surface completely but avoid rolling
on too thick of a coat. Best results are obtained with thin coats rather
than thick ones. Thick coats can cause blistering and bubbling. First
roll up and down, then cross ways.
- Allow the first coat of
Dura-Bond to dry overnight. 4) Repeat the procedure in sections B and
C above to
apply the second coat of Dura-Bond. 5) Since Dura-Bond cures to a smooth,
ceramic-Iike finish it is important to apply non-skid material to areas
where people will be walking, such as steps, loveseats, and other shallow
areas. Immediately following the application of the final coat to these
areas, and while the Dura-Bond is still tacky, sparingly broadcast a
nonskid material over any area where a non skid surface is desired.
Marble dust or white sand usually works well for this purpose.
Allow the final coat of Dura-Bond to cure for 48 hours prior to filling
the swimming pool with water. In colder temperatures wait until Dura-Bond
is dry to the touch.
Dura-Seal (A product of Delta
Coatings, Inc.)
Dura-Seal and it's benefits for the Paint Trade Concrete is a man-made
product consisting of cement, sand, gravel and water. The cement element
of concrete contains lime. As these components cure, water is expelled
leaving pores in the concrete. These pores allow for water and many other
pollutants to not only penetrate into the concrete from the top, but also
creates a capillary action allowing water and minerals to wick up from
the ground behind the pool. As the water passes through the concrete from
the soil, it picks up free lime and alkali in the concrete. The alkali
reacts with any surface coatings such as polyurethane, epoxy, adhesives,
etc... and causes a reaction known as "saponification" (forms a thin layer
of soap). When the alkaline water comes in con- tact with surface coating,
it begins deteriorating causing alkali bubbles and blisters. The coating
cracks and peels requiring replacement of the coating. Therefore, it has
been determined that there needs to be a "sealant . under the coating
and that is where Dura-Seal comes into the picture.
Dura-Seal to the rescue!
Dura-Seal is a high performance concrete/plaster sealer designed to eliminate
ground water penetration. It is designed for use prior to the application
of Dura-Bond epoxy coating. Dura-Seal penetrates the concrete and reacts
with the alkali forming small crystals in the tiny void spaces creating
a productive outcome rather than a destructive one. It turns into a I
gel and spreads throughout (not only on top). The concrete filling the
1 pores and hairline cracks, thus preventing the leaking of water through
the l concrete and to the surface. By filling the voids, it also increases
the density of the concrete. This gel becomes hard like the surrounding
concrete.
Benefits of Dura-Seal
Penetrates into the concrete leaving no surface film. When properly applied,
will not interfere with the applications of Dura-Bond. Stops alkali problems
and retards capillary seepage. May be applied to wet or dry, new or old,
rough or smooth surfaces. Creates a waterproof but breathable concrete
surface. Water based -easy clean up. For complete details on Dura-Seal,
