AquaLuster™
Application Guide Acrylic Pool Coating
Overview AquaLuster is formulated to offer tremendous advantages while
complying with strict environmental and state VOC regulations. This
acrylic coating can topcoat virtually all types of coatings and damp
surfaces that traditional solvent based paints like chlorinated and
synthetic rubbers do not. In addition, AquaLuster cures to a high gloss
finish, similar to Ramuc Type A.
For proper recommendation and compatibility purposes, the existing paint
type should be determined prior to recoating. If unknown, a core sample
with the paint attached should be submitted to the Ramuc lab for a
complete analysis. A Ramuc dealer or distributor can assist with this
free 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.
DO NOT USE ON FIBERGLASS SURFACES, HOT TUBS OR SPAS, OR WOOD.
Supplies
Needed
Cleaning products:
Tri-sodium phosphate (TSP)*
Muriatic or sulfamic acid* solution
OR “Clean and Prep Solution” by Ramuc, an environmentally safe product
that cleans, etches and neutralizes
High-pressure (3000 p.s.i. minimum) power washer with a turbo tip
attachment
Sandpaper, #80 grit, power sander, block sander or wire brush to create
a medium grade sandpaper profile for previously painted epoxy surfaces
Painting supplies:
No thicker than 3/8” nap roller
Paint brush for detailing**
5 gallon bucket for boxing (intermixing) paint
Mechanical mixer (this simply can be a paddle attachment** to a power
drill)
Soap and water for cleaning-up tools and spills
Joint or crack filler:
Hydraulic cement or Durathane® polyurethane sealant or any other
submersible polyurethane sealant. Do not use silicone-based products, as
paint adhesion will be adversely affected. Durathane must be topcoated
before submersing with chemically treated water.

General
Surface
Preparation
ALL surfaces must be free of dirt, chalk, oil, loose paint or foreign
material that may prevent adhesion. Previously epoxy-painted surfaces
must be gloss free by abrading with a wire brush or sanding with
80-100-grit sandpaper to achieve a rough surface prior to cleaning.
Power wash using minimum of 3000 p.s.i. with a turbo tip nozzle to avoid
gouging. Scrub all surfaces with a solution of TSP, especially around
the water line and steps with a stiff bristle brush. Following the
manufacturer’s instructions, wash/etch with a 30-40% solution of
muriatic or sulfamic acid to dissolve any mineral salts or chalky
material. Neutralize the acid treated surfaces with a solution of TSP,
flushing well with clean water; surfaces should be constantly wet while
cleaning. Bare surfaces should have the feel of 120-grit sandpaper after
being etched.
The above process can also be achieved using “Clean and Prep Solution”
by Ramuc, the economical cleaning product recommended for all surfaces.
Follow all instructions thoroughly.
Application
Mixing AquaLuster: Mechanically mix with a paddle attachment on a drill,
along with intermixing (boxing) the material being used for color
uniformity.
AquaLuster can be applied with a brush or roller. Use no thicker than a
3/8” nap roller. Outdoor application is recommended in early morning or
evening when the surface is cool. Do not paint in direct sunlight. Apply
2 coats of AquaLuster waiting a minimum of 6 hours between coats. In
areas of low humidity (less than 20% and higher temperatures, over
90°F), dampen the surface with a light mist of clean water for best
adhesion. Once application is complete, wait a minimum of 5 accumulative
dry days before filling outdoor pools, and 7 days for indoor pools.
NON-SKID SURFACES: Mix one pound of Skid-Tex per gallon of AquaLuster
and apply as the final coat to any walking areas such as the steps and
shallow end floor.
Do not paint when rain is imminent. Use dark colors for accent painting
only.

Cure Rates
Outdoor pool: 5 dry days
Indoor pool: 7 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 or
discoloration. Dry time to touch: 15 minutes
To recoat: 6 hours
To touch: One hour at 70 degrees minimum
Finish: High Gloss
Primer: No primer required. All Ramuc paints are self-priming
Fill outdoor pools after at least 5 dry accumulative days, indoor at
least 7 days with proper ventilation.
Coverage
Rates
200-250 sq. ft. on bare, sandblasted, or rough surfaces
400-450 sq. ft. on recoats
(Actual coverage will vary and is dependent upon the porosity and
profile of the surface)
Minimum dry film per coat: 1.5 mils dry (3.4 mils wet)
Maximum dry film per coat: 2.0 mils dry (4.2 mils wet)
Clean-up: Soap and water

Special Situations
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. 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.
• Extremely corrosive water can ultimately cause deterioration or
breakdown of a paint film over a period of years.
The solution:
• Scrub surface using a soft bristle brush and a solution of soap and
water.
• Standard pool water chemistry balance levels should be maintained as
follows: pH 7.2-7.6; Alkalinity 120-150, chlorine 1.0-3.0; calcium
hardness 200-300 ppm.
AquaLuster
Blistering
The cause:
• Applying paint too thickly.
• Applying over chalk, algae or dirt.
• Applying to a too hot or too dry
surface.
The solution:
• Pressure wash affected areas or scrub off blisters.
• Scrub with “Clean and Prep Solution.”
• Dampen or mist the surface prior to painting.
