DO’s and DON’Ts for Your New Pool Finish

The interior cementitious (plaster) finish of your pool is the only cosmetic part of your pool that is handcrafted in an uncontrolled environment. The curing of a plaster finish will occur over the next 10 to 12 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. 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. 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. During this period it is essential that conscientious start-up and maintenance procedures be followed to prevent the finish from developing an uneven appearance. These discolorations appear as gray spots, gray cloud like colors, irregular streaks, white or lighter pasty areas or streaking, and yellowing. It is imperative that you follow the following procedures or consult a well-trained, well-educated pool professional. The builder, applicator, and manufacturer of your pool finish warranties your pool surface as a team. You and your service company become part of that team as the maintenance operator.

The “Start-Up”
Filter 24 hours per day for 2 weeks
Day 1: Reduce alkalinity & pH, add sequestering agent
Day 2: Test alkalinity, pH, & sequestering agent, adjust
Day 3: Lower alkalinity & pH if required, add chlorine
Week 1: Brush pool 2 times per day
Week 2: Brush, lower alkalinity & pH
Week 3 & 4: Brush, lower alkalinity & pH
Year 1: Lower alkalinity & pH as required
