OVERVIEW
Ramuc
Type DS Acrylic is formulated to offer tremendous
advantages over traditional solvent-based paints.
Acrylic coatings can and should be applied to a damp
surface, can be applied to almost any painted surface,
will clean up with soap and water, and can allow the
pool to be filled within 3 days after the final application
of paint making them the paint of choice where short
down times are critical. Water-based acrylics are
extremely colorfast and UV resistant. Most acrylics
are a satin or flat finish and will stain easier than
solvent paints. Because of the nature of the acrylic
paint surface, the service life of acrylic water-based
paint will wear faster than chlorinated rubber or
epoxy type paints.
For compatibility purposes, the existing paint on
previously painted surfaces of a pool should be determined
before painting. If existing surface is unknown, a
sample should be submitted for testing to determine
the type of existing surface. Paint chips can be taken
to any Ramuc distributor/dealer to be forwarded to
the Ramuc laboratory for analysis.
Aged plaster should be checked for integrity. Check
for hollow or weak/crumbling plaster by using a ball-peen
hammer or any other comparable method. Perform repairs
to the plaster before painting.
SUPPLIES NEEDED:
The keys to a successful pool or deck paint job are
proper SURFACE PREPARATION AND CORRECT APPLICATION.
By following these simple 1-2-3 steps, you're ensuring
virtually maintenance-free paint service on your pool.
GENERAL SURFACE PREPARATION
Immediately after the pool is emptied, begin the
3-step process.
- STEP 1- Plaster, concrete, or gunite surfaces
should be tested for integrity and soundness. Pool
paint is not a Band-Aid for weak surfaces. Water
blast the surface to remove loose paint and dirt.
If painting over existing epoxy, the surface must
be sanded/abraded to achieve an #80 grit profile.
Then, scrub the entire pool with a soap/tri-sodium
phosphate (TSP) solution to remove all dirt, oils,
loose or peeling paint, and chalk. Should any minor
repairs need to be made, such as hydraulic cement
patch or crack joint filling, do them at this time.
Follow the manufacturer’s recommendations.
- STEP 2- All surfaces should then be acid etched
with a 15-20% solution of muriatic or sulfamic acid
to achieve a medium grade sandpaper finish on bare
concrete or plaster and to remove mineral deposits
on previously painted epoxy surfaces. Neutralize/rinse
with TSP and water.
MIXING THE PAINT - Type DS Acrylic is self-priming;
no other type of primer is recommended or should
be used. Mechanically mix the paint to achieve uniform
consistency and color. If you are using more than
one (1) gallon of paint at a time, remember to box
(intermix) several gallons together.
APPLICATION
- STEP 3- Use no more than a 3/8" nap mohair
metal, lambskin, phenolic core roller. Apply at
the recommended coverage rate. Ideal air temperatures
for application are between 50-90ºF. Surface
temperature should be at least 50ºF.
Do not paint when rain is imminent. Use dark
colors for accent painting only.
CURE RATES
Outdoor pool - 3 dry days
Indoor pool - 6 days
If rain occurs during the curing process, allow
an extra day of dry time for each day of rain.
Rain or moisture can cause blistering, color blushing,
and the finish could be altered. Dry time to touch
- 15 minutes
To recoat - 4 hours
Finish - flat
Primer - all Ramuc paints are self-priming
COVERAGE
175 - 200 sq.ft. on bare, sandblasted, or rough
surfaces.
350 - 400 sq. ft. on recoats
(actual coverage will vary and is dependent upon
the texture and profile of the surface)
Minimum dry film per coat - 1.2 mils dry (3.2
mils wet)
Maximum dry film per coat - 1.4 mils dry (3.7
mils wet)
Clean-up - Soap and water

SPECIAL SITUATIONS
I. BLUSHING - FADING - CHALKING
The cause:
* The "shock" of calcium hypochlorite
can cause a white, bleached look to the paint
film, leaving a whitish deposit
* A chalky substance can be created by over treating
the water with shock, bromine, ozone and ionization.
It is not the paint breaking down. We suggest
a natural polymer product or clarifier that can
reduce the chalking problem.
* Iron in the water from rust in the filter system
may leave deposits and stain the film.
* Painting a water-based acrylic on a too hot,
too dry surface will actually “cook”
the coating.
The solution:
* Scrub surface using a soft bristle brush and
a solution of soap and water. This will remove
surface dirt and deposits.
* Wet with a weak (2-3%) solution of muriatic
acid. Acid will remove iron stains without damaging
the paint film.
* Check your pool water chemistry daily or weekly
for:
o 1. Calcium hardness
o 2. Total alkalinity
o 3. pH
* Extremely corrosive water can ultimately cause
deterioration or breakdown of a paint film over
a period of years.
II. BLISTERING
The cause:
* Applying paint too thick
* Applying over chalk or dirt
* Applying to a too hot or too dry surface
The solution:
* Apply at recommended coverage rates. Thicker
is not better when applying to pool paint.
* Dampen or mist the surface prior to painting
* Clean/scrub/and abrade prior to painting
