Cracks
One of the most common problems that can arise with pool plaster is cracking. Cracks might appear for several reasons, such as the use of the wrong plaster mix or incorrect application. Natural factors such as sun exposure and water erosion might also cause cracking. If the cracks are small, you can easily fix them using simple pool repair kits available at swimming pool stores. However, deep cracks require a more in-depth repair process, which might involve sandblasting and chiseling.
Stains
Pool stains are another common problem that can arise with pool plaster. Stains might arise due to various factors, such as chemical imbalances, poor filtration, or prolonged exposure to leaves or other debris. The good news is that stains are one of the easiest problems to fix. You can use acid washing or pool stain chemicals to remove the stains effectively. However, it is essential to determine the cause of the stain before fixing it. If the source of the stain is a chemical imbalance, it is essential to adjust the pool water chemistry.
Efflorescence
Efflorescence is a common problem that occurs due to the accumulation of salt or calcium deposits on the surface of the pool plaster. It occurs when the pool’s water evaporates, leaving behind salt or calcium deposits. Efflorescence leaves behind a white, chalky deposit that is challenging to remove using conventional methods. The best way to fix this problem is to apply a water-resistant sealer that protects the plaster from the accumulation of calcium or salt deposits.
Discoloration
Discoloration is another problem that can occur with pool plaster. It often arises due to various reasons such as salt or chemical imbalances, improper water balance, or prolonged exposure to sunlight. Additionally, algae and bacteria growth can cause discoloration to your pool plaster. The best way to fix discoloration is by identifying the cause and treating it. If the issue arises due to chemical imbalances, it is essential to correct the balance. If the cause is algae growth, it is necessary to shock the pool and apply algaecide.
