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 (Recommended)

 

Condensation test material:
Several two-foot square transparent pieces of plastic
Duct tape
 

Painting supplies:
No larger than 3/8" nap roller² made for solvent based paint
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 roller made for solvent based paint.  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 Painting over any silicone primers or selants including curing agents 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.
