Reasons for Cracking and Discoloration Your Pool Surface
With time your plaster becomes aged, it starts showing signs of degradation. Depending on a variety of factors like poor water treatment and environmental factors, your pool plaster's longevity can decrease. The durability of a pool highly depends on the quality of plaster, and yearly maintenance.
Sometimes, even after applying a pool interior finish, many problems arise like cracking and discoloration. These issues can appear soon after the construction or many years later. Here is a list of causes of discoloration and cracking over the years. If you want to know the causes of cracking and discoloration of your pool plaster, then read the article below.
1. Organic Matter
The worst enemy of pool plaster is the organic matter surrounding it. It damages the plaster and causes bad stains on among the surface of your pool, which makes your pool look less than appeasing over time. Organic matter like trees, plants, leaves, and grass disturbs the water balance and damages the plaster.
As mentioned above, organic matter also causes nasty stains, specific flowers, and leaves when sinking into the pool. The stains on the pool plaster make it look unappealing. Leaves with a high concentration of tannin as nut trees are very known for causing stains on your pool.
2. Foreign Objects
All the tools used in the ground are made up of steel; when they drop into the pool, they cause a brown stain. Children's toys with metal or steel parts are also responsible for the same color stain. Other household objects like coins, nails, needles can also cause stains on pool plaster.
Moreover, fertilizers used around the house and for plants are also notorious for plaster stains. The color of these stains is rusty brown. The major component of fertilizer is iron, which is found in most things present in the house and can be thrown into the pool by child, causing unwanted pool stains.
3. Variable Calcium and Alkalinity Levels
Some sort of discoloration and scaling occurs when dents are formed in pool layers over time. Scaling and discoloration is also caused by poor water balance chemistry. High alkalinity and calcium also cause scaling of pool plaster. Scaling can accumulate calcium and other minerals in your pools that are not beneficial for your pool health.
On the other hand, etching is caused by low alkalinity and calcium. It is vital to take care of your pool appropriately to avoid such issues. You can prevent these issues by regular brushing of your pool walls, pre-diluting acids, and not adding salt when plaster is fresh. The recommended calcium levels for a pool is 200 to 400 ppm, and recommended levels for total alkalinity for healthy pool chemistry is between 80 ppm to 120 ppm.
4. Concrete Shrinking and Shifting
Over time, there are shifts in the concrete that affect the pool area, such as pool decking, pool coping, and pool surface. Concrete shrinking or flexing causes small superficial cracks called crazing. Crazing can come from numerous causes being; construction of the pool done in a very hot or cold environment, as well as taking too long to fill the pool .
NOTE: If a pool is not filled within 48 hours upon completion, damage will be caused to the pool surface. This is why post plaster treatment is critical for the care and longevity of your plaster health.
A small amount of crazing is usually acceptable, but if you see more than usual crazing, you should contact your pool remodeling professional for further assistance. These are small cracks so that they won't cause any leakage. When deep cracks are present, leaks inside of the pool surface have a greater chance of appearing.
