PROCESS AND CUSTOMER Q & A PAGE

Traditional refinishing process:

1. Drain pool.
2. Prepare surface for bond coat, it must be dirt, oil or other foreign material free (acid/pressure wash if needed).
3. Remove hollow areas when applicable.
4. Remove and replace existing tiles, if applicable.
5. Cut and chip old plaster from under existing perimeter tiles and around all return lines for a better transition of new plaster.
6. Apply a bond coat containing cement glue to ensure that new plaster will adhere to old plaster.
7. Apply 3/8 to plaster, trowelled to a hard smooth finish.
8. Fill pool with potable water.

Process for pebble finishes:

1. Drain pool.
2. Prepare surface for bond coat, it must be dirt, oil or other foreign material free (acid/pressure wash if needed).
3. Remove hollow areas when applicable.
4. Remove and replace existing tiles, if applicable.
5. Cut and chip old plaster from under existing perimeter tiles and around all return lines for a better transition of new plaster.
6. Apply bond coat containing cement glue to ensure that pebble finish will adhere to old plaster.
7. Apply average inch pebble finish.
8. Next day acid wash to expose pebble.
9. Fill pool with potable water.

GUIDELINES FOR NEW AND REFINISHED POOLS

1. Once your pool has started to fill with potable water, do not turn water completely off., if you suspect your pool will over fill while you are away, simply turn volume down to a trickle. Consider pool full when water level reaches the middle of perimeter tiles. Failing to keep water flowing until full, could result in shrinkage/stress cracks and/or permanent water line on plaster.
2. Do not allow anyone or pets on plaster until full. (Plaster stains easily until it is fully hydrated).
3. Brush entire plaster surface with nylon brush once or twice a day for at least 14 days, after plastering. This will help remove alkali dust off of the curing plaster. (Backwash filter, when pressure rises, to remove alkali dust from filter).
4. Balance pool water, testing daily, for 30 days. Run pump and filter for at least 30 days, after plastering, continuously for the first four to five days.
5. PH level should be kept at 7.0 for the first 30 days, this will also help minimize the alkali dust. Adjust PH to 7.4 after 30 days of plastering application.
6. Alkalinity should be kept between 70 80 parts per million.
7. Keep calcium hardness between 200-400 parts per million.
8. Chlorine level should be kept according to test kit recommendations.
9. Cyanuric Acid level should be kept between 30-50 parts per million. If cyanuric acid level exceeds 50 parts per million, drain about 2 feet of water from pool, then add potable water back into pool.
10. We recommend you do not turn pool heater on for at least 3 weeks after plaster application.
11. We recommend you do not use any water falls or fountains unless necessary, until start up is complete.
12. If you are using a salt chlorinator, we recommend you do not add salt for 30 days, after plaster is applied.
13. We recommend you do not use a wheeled vacuum, for a couple of weeks, as it can mar plaster because of alkali dust.

Note: Studies have shown that maintaining proper water balance is critical to the longevity of all pool finishes.

CUSTOMER Q & A:

Why are the first 30 days so important?
The first 30 days are crucial for a newly plastered pool. This is the time your plaster goes through the curing process. Pool water must be monitored closely, to prevent scaling.

Why do I have to brush my pool after it is plastered?
With traditional plaster you may have plaster plaster scale (dust) on the bottom of the pool but this will go away with proper maintenance and brushing. The more you brush the better.

How should my finish feel?
Traditional plaster should be a smooth surface. Pebble surfaces will feel bumpy.

Why are there pebbles falling out of my finish?
With pebble finishes it is normal to experience a small loss of pebbles right after the finish is applied and acid washed during the start up time.

How long does it take to have your pool plastered?
It depends on the season. The swim season (March September) is a very busy time of year for pool companies. We can plaster most anytime of the year however weather (rain, extreme cold, extreme wind) sometimes becomes a factor.

Who drains the pool?
You do. If you need help with this we will be happy to assist you.

How long before we can swim?
As soon as the pool is FULL of water.

What is the best time of year to have my pool plastered?
Anytime, weather permitting, however wait time is usually shorter in the fall and winter.

How long should my plaster last?
A residential pool, if water is kept and balanced properly, could last 10 to 15 years. Due to the large amount of chemicals that have to be used a commercial pool could last from 5 to 10 years.

What if my pool is painted?
If your pool is painted it will have to be sandblasted before a bond coat is applied, for the warranty to be applicable.
