Ultra PearlBrite™ is a state-of-the-art, pre-blended pool plaster designed to provide an exceptionally smooth, radiantly white, and long-lasting finish. A unique formulation of the whitest marble aggregates, premium white cement, and performance-enhancing admixtures, Ultra PearlBrite is resistant to common pool plasters problems like spot etching, staining, pop-offs, and discoloration. High tech admixtures reduce permeability and improve chemical resistance.
Examine pool surfaces to identify conditions that might interfere with the proper bonding of coating. Look for algae, mold, mildew, dirt, paint, mortar droppings, efflorescence, patching compounds, loose tile, cracked plaster, et cetera. Clean pool surfaces of all material that might interfere with the proper bonding of coatings. Clean with high-pressure water or by sandblasting. Wash with chlorine until algae, mold, and mildew are gone. Remove oil and grease spots using trisodium phosphate or equivalent and water; soak if necessary. Remove all cleaning solutions via high pressure- washing. Identify hollow spots in plaster by sounding. Remove and repair all hollow and delaminated plaster. Saw cut an area 3 inches around bad spots and remove plaster inside the saw cut. Undercut the edges of the remaining plaster. Fill holes with specified patching cement (SGM Mortar Mix and Southcrete™ 25 Acrylic Admix) to level of existing plaster. Remove loose tile and fittings; undercut existing plaster two (2) inches below the tile line, and around return lines and fittings to a depth of ⅜ inch. Stop water penetration from the outside pool. Plug cracks and leaks around fittings using hydraulic cement (SGM Dynamite Pool Patch). Etch clean the surface with a muriatic acid solution. Use concentration necessary to clean and roughen the surface; smooth surfaces may require higher concentration. Neutralize surface with a solution of baking soda and water to eliminate acid residue, which can cause bond failure. Remove remaining acid solutions via high pressure-washing. Plug pool inlets and outlets to prevent clogging with expandable plugs or threaded caps. Mark location of fittings using tape on coping or on a measured drawing. Place the sump pump at the main drain to remove all running and standing water. Do not begin installation until the concrete pool shell has cured at least twenty-eight (28) days. For renovation projects (plastering over an existing plaster pool finish) and poured or formed concrete shells apply SGM Ultra PearlBrite™ as directed. Allow Ultra PearlBrite to cure for at least six (6) hours before plastering. Plaster should be applied to SGM BOND-KOTE™ within three (3) to five (5) days. If left for a longer period before the finish is applied, ensure Ultra PearlBrite is clean and free of dirt, efflorescence, and other contaminants. If necessary, clean BOND-KOTE by brushing vigorously while spraying with water; chlorine may be used as needed.
Ultra PearlBrite is made in batches of 4,000 to 20,000 lbs. (1,800 to 9,000 kgs.) using natural ingredients. For this reason, there will be variations in shade between batches. Batch numbers are printed on the ends of every individual bag. It is important the user follow these instructions carefully to ensure the most consistent color throughout the pool.
Each 80 lbs. bag will cover approximately 22—25 sq. ft., to a thickness of minimum ⅜ inch to ½ inch. Surface roughness affects coverage rates.
Although it is not necessary to use a plaster pump, many contractors do. Included here are some helpful hints for successful pumping. Increase the size of the pump manifold from three (3) inches to four (4) inches. Change the valve ball from plastic to steel to improve longevity. Set the plaster pump to the lowest gear by moving the belt. Always begin pumping with a full stroke on the main piston. This is accomplished by advancing the wheel until the cam is at its highest position. Prepare a slurry of cement and water or pump aid and run it through the pump first to prime the pump and lubricate the hoses. Pour the mixed plaster slowly into the pump hopper. Do not pour all the material in at once. Agitate the material in the hopper to prevent separation of the cement and aggregate. Avoid unnecessary stopping during the pumping process. Ultra PearlBrite aggregate will tend to settle in the pump manifold and hoses when the pump is stopped. Agitate the remaining material left in the hopper to reduce clogging. Do not try to clear a blockage using the pump. Disassemble and clean the manifold and hoses when clogged. Do not over-water mix. This will only cause the material to separate, clogging the pump and hoses.
The substrate should be cool and damp but not dripping wet. Mist shell with cool, clean potable water. Non-absorbed water may be removed by using sponges and/or air. Standing water will weaken Ultra PearlBrite and may cause washouts.
Apply plaster liberally with the flat side of the trowel using sufficient pressure to key in a scratch coat on the vertical surfaces. Beginning with the shady walls and working to the sunny walls, trowel a scratch coat on the walls and allow to set up until it becomes tacky. The set time will vary according to temperature and humidity. Once the scratch coat has become tacky, apply a finish coat to the entire pool surface beginning in bowl area and working toward the shallow end, troweling and blending walls and floor together to achieve a seamless appearance while working to a final thickness of one-half (½) inch (10 mm—12 mm). Uniform troweling will help to ensure even exposure, reduce washouts and produce a comfortable slip-resistant finish. The technique of “slick troweling” is recommended. During the application, make several passes with pool trowels to compact the aggregate and ensure a smooth dense finish. In this process, the cement paste is brought to the surface during troweling and is removed with the trowel. This produces a slick surface and minimizes the exposure needed. Small amounts of lubrication water may be necessary for smoothing out and compacting the finish in this process. The aggregate can be seen through a thin film of cement paste after troweling is complete. Special attention must be given to the filling in of spike holes. The applicator must be careful to fill all spike holes with Ultra PearlBrite aggregate to avoid visible spike holes. Extra care must be taken to ensure proper troweling in the coves and corners. Specialty trowels are required for these areas. Insufficient troweling in these areas will result in roughness and washouts (loss of cement and aggregate) during the exposure process.
Once you have completed slick troweling the entire pool surface. Allow the Ultra PearlBrite finish to cure overnight. The following morning start by acid washing the surface with muriatic acid and water. Start with a fifty (50) percent acid, fifty (50) percent water solution and adjust the concentration as needed. The acid solution should be just strong enough to remove most of the cement paste from the surface. Upon completion of acid wash, rinse pool shell down thoroughly. Now you are ready to polish. Proper safety equipment must be worn at all times. Begin polishing the walls first and then the floor. Following this procedure will minimize the risk of falling on the slick wet Ultra PearlBrite surface. Start by using a 70-grit Hone Diamond Disk and lightly polish the entire pool surface. In most cases one pass is sufficient to produce a smooth surface however in high contact areas such as swim outs and spas; a second pass with a 120-grit Hone Diamond Disk may be required. Dispose of wash solution according to local requirements.
In accordance with National Plasterers Council (NPC) standards, it is recommended that the following pool and spa water chemistry conditions be maintained on an ongoing basis for the longevity of Ultra PearlBrite interior pool and spa finish. These values are important to prevent corrosion, deterioration, discoloration, scaling or other problems. For more information refer to your local agency having jurisdiction or NPC. Follow recommended fill and balancing procedures to ensure a successful start-up.
Fill pool completely and without interruption with clean, potable water. The use of a filter during fill is strongly recommended. The initial fill water is the most important water that the pool will receive and must be tested, recorded and adjusted according to the following parameters by an experienced pool professional. For the first thirty (30) days the pH and alkalinity must be monitored and adjusted (if applicable) every three (3) to five (5) days. All other chemicals monitored and adjusted (if applicable) every seven (7) to ten (10) days. The pool water must be tested regularly and documented monthly by a reputable company using a computerized system. Monitoring the pool water regularly will not only affect the new finish but will keep the Ultra PearlBrite finish looking new. Improper water chemistry will void the five-year limited residential warranty. It is recommended that a quality sequestering agent be used in the initial start-up in accordance with the manufacturer’s instructions and then a recommended maintenance dosage per the sequestering agent’s manufacturer instructions.
