During this period it is essential that conscientious start-up and maintenance procedures be followed to prevent the finish from developing an uneven appearance. The pool is attempting to grow crystals (a scale, plaster dust) on the surface that will look unsightly within the first 24-hour period, up to the first year if not controlled by brushing and water chemistry. 60% of the maturing process is accomplished within the first 28 days and the balance of the maturing process over the next 8 to 10 months. This curing or maturing process causes the alkalinity, pH, and calcium levels to rise on their own as the pool actually grows calcium hydroxide, calcium carbonates, and calcium silicates which strengthens and seals the porous surface of the new finish. The curing of pool plaster occurs over 10 to 12 months. The interior plaster finish of your pool is the only cosmetic part of your pool that is handcrafted in an uncontrolled environment.

Here’s the complete day-by-day pool startup procedure after plastering.Pool Plaster is not intended to be a slick finish. Testing and adjusting the cyanuric acid level.Testing and adjusting the chlorine level.Testing and adjusting the calcium hardness.A high pH causes cloudy water and scaling on pool equipment.Īfter filling water and running the filtration equipment, you can proceed with the other startup instructions. This is because calcium hydroxide in the plaster leaches into the water, causing the pH level to rise. The filtration equipment should run continuously for at least 72 hours. The cloth also catches small debris in the water. Then, tie a soft, clean rag to the end of the hose to prevent water from sloshing. Prevent Damage from Sloshingįill the pool using a garden hose. Stopping the flow can create rings in the plaster at the point where you stop. You cannot stop the flow or pause until the pool is full, and this is when the water reaches above the tile line. Hence, it’s critical that you use water from on-site (garden hose), public water, or trucked-in water. Water has a strong impact on the plaster’s finish. Here are some critical water filling guidelines by the National Plasters Council. Most household pools with a 20,000-liter capacity take 24 – 32 hours to fill. After plastering the pool, you should start filling the pool right away. It can seem relatively simple, but there are important things to know. The initial water fill is critical to new plaster.
