Properly Opening a Freshly Plastered Pool

The first 30 days after a swimming pool has been plastered are the most important.  It is critical that the plaster is properly cured.  This is done by maintaining a proper balance in the pool waters chemistry and maintaining it throughout the life of the pool.  When starting up the pool the main objective will be to clean and get rid of the dust left over from the plaster while stabilizing and balancing the water that is in the pool.  This article will give you a few things to consider if you are contemplating having the plaster on your swimming pool re-done or a new plaster pool installed.

The Quality of the Water You Are Adding to the Pool

Before you begin to add water to a freshly plastered pool it is important to know the quality of the water.  Believe it or not all water is not the same.   The quality of the water in your home may not be the same as the quality of the water in the water spout outside of the home.  The local source that you have for filling the pool may not be suitable.  It is important to take a sample of the pools water to a pool retailer to have it analyzed.  Write down the water’s chemistry for reference at a later date.

Determine How Much Water Is Needed for The Pool

If you determine that your water source is appropriate for filling your swimming pool the next step is to take a meter reading to make sure the source is adequate to fill the pool without issues.  To measure the amount of water needed to fill a swimming pool use the following measurements:
Oval – Length x Width x Average Depth x 5.9
Round – Diameter x Diameter x Average Depth x 5.9
Square/Rectangle – Length x Width x Average Depth x 5.9
Irregular Shapes – Divide the pool into geometric shapes and add the gallon amounts together

Starting the Pool Filling Process

After the pool has been plastered, the water has been tested, and the amount of water needed to fill it is determined it is time to fill the swimming pool.  When filling the pool use a clean hose with a soft cloth tied to the end to diffuse the water so that it does not whip about and mar the freshly plastered surface.  It will also catch debris coming out of the hose.
If you are bringing water in via a truck note that a cushion of two feet is needed in the bottom of the pool.  Water should be added quickly but in a manner that does not harm the plaster.  If a pool fills too slowly cracks may appear.  In order to avoid this the plaster should be added in as quickly as possible.
Tips:

• Do not let the hose flip and flail around the pool
• Put the fill hose in at the deep end of the pool
• Do not allow the hose to rest on the fresh plaster
• Do not add anything to the pool until it has finished filling including clarifiers
• Do not stop the water until the pool is completely filled
• Do not walk on the freshly plastered pool 

Test the Water After It Has Finished Filling

The water may test substantially different once the pool has been filled.  It is important to test the water and write the current water chemistry down.  The pools water must have the correct chemistry to prevent staining or pitting.  Calcium is especially important to the pools water chemistry.  If the calcium is not maintained, it will pull calcium from the plaster which could cause issues to the plaster surface.
