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:
Cleaning products:
Tri-sodium phosphate (TSP)1
Muriatic or sulfamic acid1 solution
High-pressure power washer (Recommended)
Abrasion material used to create a medium grade sandpaper profile for previously
painted epoxy surfaces only:
Sandpaper #80 grit, power sander, or wire brush
Painting supplies:
No larger than 3/8" nap roller2
Paint brush for detailing2
5 gallon bucket for boxing (intermixing) paint
Mechanical mixer (this simply can be a paddle attachment2 to a power drill)
Soap and water for cleaning-up tools and spills
Joint or crack filler:
Hydraulic cement1 or Durathane polyurethane sealant or any other submersible
polyurethane sealant. Do not use silicone-based products, as paint adhesion will
be adversely affected.

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 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:
1. Calcium hardness
2. Total alkalinity
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
Painting over any silicone additive primers or selants including curing agents
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
