Curing Your New
Pool Surface

The critical care after the installation is complete.

Resurfacing your pool is one of the largest investments you will have regarding your swimming pool. The resulting appearance and longevity of the pool surface is determined by the care provided in the first four weeks after the installation. Proper steps for curing a new plaster require mandatory procedures such as: timely brushing, constant monitoring and adjusting of the pool water chemistry. Communication between owners and the pool company is of the utmost importance. It is critical that you confirm that the pool will be properly maintained and the job will include the extra work necessary for the curing process.

Why is curing your new plaster important?

The installation of a new plaster surface causes fluctuations in the water chemistry. The alkalinity, pH and calcium levels will rise while the surface is curing. The new plaster is susceptible to staining and discoloration during the first four weeks. The proper curing procedures will help reduce these imperfections plus scaling, pitting and gray streaks or spots. These procedures will also reduce the amount of “plaster dust” on the pool surface and will result in a smoother finish for the pool users to enjoy.

What to look for in a vendor?

There are some pool companies who will offer the plastering job at a lower price; however, the work is usually finished the day that the plaster is installed. You have to discuss the specifics of the curing process with the vendor to be sure it is not omitted after the job ends. The curing process is vital to ensure that this investment will last. We recommend you use a professional firm that comes highly recommended and is financially sound for this type of work. The selection should be a member of the National Plasterers Council (NPC) as well.

What does curing a plaster mean?

Curing plaster refers to a maturation process of the new plaster finish when it strengthens and seals. The pool finish will start to cure immediately after mixing. Sixty percent of the curing process occurs in the first 4 weeks and will continue over the next 8 to 10 months. This is when the final outcome of the surface is determined. If done correctly, you will extend the life of the plaster and ensure the pleasing aesthetics of the swimming pool surface.

What are the steps in curing a plaster?

There are specific “start up” procedures that need to be followed to ensure the plaster cures properly. These steps include filling the pool, turning on the filter system, checking the water chemistry and brushing the pool. During the first 4 weeks it is very important to keep the water balanced. This is done through ongoing testing of the water chemistry and making necessary chemical adjustments. The pool must also be brushed daily.

Due to the variances in the water supply, site specific conditions and environmental factors, the recommended procedures will need to be adjusted to protect the pool finish and produce the best results. We advise all pool owners that the selected vendor follows industry standards outlined by the National Plasters Council and has completed the necessary training. The NPC certification for this work is “Start Up Technician”.

What can happen if I do not cure my plaster?

The secret to the long life of any pool surface is properly maintained water chemistry and appropriate surface care. Improper water balance will destroy any pool surface and can be especially harmful to a vulnerable new plaster surface. If it is not maintained properly, the new plaster will be rough and staining or discoloration will occur.

To ensure the investment in a newly plastered pool surface is a sound one, communication between the owner and the installer is of upmost importance. Be sure to address the specifics of the curing process, as it is vital to the longevity of your investment.
