Thorough Pool Plastering Start-Up Procedures
There are certain start-up procedures to ensure your swimming pool plaster is cured properly. The pool finish will start to hydrate immediately after mixing, with the majority of hydration taking place within the first 28 days. This critical time period is when a finish is most susceptible to staining, scaling, and discoloration. Proper start-up procedures, including timely brushing and constant monitoring and adjusting of the pool water are essential and mandatory.
The following recommended start-up method is based on procedures shown to produce the best aesthetic results. Due to unique local water conditions and environmental factors, parts of these recommended start-up procedures may need to be modified to protect the pool finish.
For example: filling the pool with water having extremely low calcium hardness, low pH, or low total alkalinity levels may necessitate changes to these procedures. Brushing and monitored chemical adjustments will need to be carried out on a regular basis by the homeowner or a trained pool technician during the service life of any pool surface. Always add a chemical to the water and never water to the chemical. Contact

Pool Filling Day
Step 1. Make sure the filtration equipment is operational.
Step 2. Remove all floor return heads and directional eyeballs (if appropriate and recommended in your geographical area).
Step 3. Based on temperature and type of finish, fill the pool to the middle of the skimmer or specified water level, without interruption and as rapidly as possible with clean potable water to help prevent a bowl ring. Place a clean rag at the end of the hose, always placed in the deepest area, to prevent damage to the surface material. If a water truck is required, 24 inches (60 cm) of water should be placed at the deepest area for a water cushion.
Step 4. At no time should any person or pets be allowed in the pool during the fill. Do not allow any external sources of water to enter the pool to help prevent streaking.
Step 5. Test the fill water for pH, alkalinity, calcium hardness, and metals. Record the test results.
Step 6. Start the filtration system immediately when the pool is full to the middle of the skimmer or the specified water level.
Step 1. Test pH, alkalinity, calcium hardness, and metals. Record test results.
Step 2. High alkalinity should be adjusted to 80 ppm using pre-diluted Muriatic acid (31-33% Hydrochloric acid). Always pre-dilute the acid by adding it to a five-gallon (19 L) bucket of pool water.
Step 3. Low alkalinity should be adjusted to 80 ppm using sodium bicarbonate (baking soda).
Step 4. pH should be adjusted between 7.2 to 7.6 by adding pre-diluted Muriatic acid if the alkalinity is already 80-100 ppm.
Step 5. Brush the entire pool surface thoroughly at least twice on a daily basis to remove all plaster dust.
Step 6. Although not required, it is highly recommended to pre-dilute and add a quality sequestering agent using the recommended initial start-up dosage and then the recommended maintenance dosage as provided by the sequestering agent's manufacturer.
Step 7. Operate the filtration system continuously for a minimum of 72 hours.
Step 8. Do not add chlorine for 48 hours.
Step 1. Test pH, alkalinity and, calcium hardness and repeat steps of 1st Day, except for Step 6.
Step 1. Test pH, alkalinity, and calcium hardness and repeat 1st Day steps 1 through 6.
Step 2. Pre-diluted chlorine may now be added to achieve 1.5 to 3 ppm. No salt should be added for 28 days.
Step 3. Brush the entire pool surface thoroughly, at least twice on a daily basis, to remove all plaster dust.
4th Through the 28th DAY
Step 1. Test pH, carbonate alkalinity, and calcium hardness. Repeat 1st Day Steps 1 through 5, every day for 14 days, to help prevent scaling.
Step 2. On the 7th day, if there is any plaster dust remaining, remove it using a brush-pool vacuum.
Step 3. After the 4th Day - low calcium levels should be adjusted slowly over the 28 day period not to exceed 200 ppm.
Step 4. After the 4th Day - adjust Cyanuric acid levels to 30 to 50 ppm based on the primary sanitizer of the pool (pre-dissolve and add through the skimmer).
