Ramuc premium Type A Chlorinated Rubber has been used in the industry for
decades restoring and protecting plaster, concrete, and gunite pool surfaces. It
is an excellent choice for recoating previously painted chlorinated rubber
surfaces and is formulated to provide excellent hiding and superior coverage
rates compared to other chlorinated rubber paints. Chlorinated rubber is not for
use on spas or whirlpools.
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 (optional)
Condensation test material:
Several two-foot square transparent pieces of plastic
Duct tape
Painting supplies:
No larger than 3/8" nap mohair metal, lambskin, phenolic core 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)
Ramuc Thinner 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. 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. Neutralize/rinse with TSP
and water.
CONDENSATION TEST- After all cleaning in completed, allow the pool surface to
dry.
Average dry times vary regionally and are dependent upon the porosity of the
surface. It is recommended to wait five dry days and then perform a condensation
test to determine surface dryness.
To determine dryness, perform this simple test - Duct tape 2' x 2' pieces of
transparent plastic to the deep end wall and floor, and on several other areas
of the pool. Wait three hours to determine if condensation has formed underneath
the plastic. If condensation has formed underneath the plastic then the surface
is not dry enough to paint. Remove the plastic and wait 24 hours to perform the
test again. Continue with the test until no condensation forms underneath the
plastic after the three-hour wait period. This ensures the surface is dry enough
to apply chlorinated rubber pool paint.
MIXING THE PAINT - Type A Chlorinated Rubber is self-priming; no other type of
primer is recommended or should be used. Ramuc Thinner can be used to thin paint
by 10%. 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 - 5-7 dry days
Indoor pool - 10-14 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 - 24 hours
Finish - high gloss
Primer - all Ramuc paints are self-priming
COVERAGE
200 - 300 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 - 1.0 mils dry (3.2 mils wet)
Maximum dry film per coat - 2.0 mils dry (6.2 mils wet)
Clean-up - Ramuc Thinner

SPECIAL SITUATIONS
I. BLUSHING - FADING - CHALKING
The cause:
The pool is filled too soon (see cure rates) before the paint is completely
cured, causing a blush over the surface which looks like fading or chalking.
Super-chlorinated water may cause a "bleached-out" look.
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.
The solution:
Scrub surface using 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.
Solvent wipe affected areas with Ramuc Thinner.
Check your pool water chemistry daily or weekly for calcium hardness, total
alkalinity, and balanced pH.
Extremely corrosive water can ultimately cause deterioration or breakdown of a
paint film over a period of years.
Be sure the newly painted pool surface dries at least five dry, sunny days
before filling.
II. BLISTERING
The cause:
Using a nap roller larger than 3/8", draws air into paint film
Applying paint too thick
Painting on a damp surface
Filling the pool before the paint is cured
Incompatible paints
The solution:
Apply at recommended coverage rates
All paintable surfaces must be dry prior to painting with chlorinated rubber
Chlorinated rubber paint must cure for 5 dry days(outdoor pool), and 10 dry
days(indoor pool)
If in doubt as to type of coating that is on the pool now, take a paint chip to
your local Ramuc dealer for analysis.
