When Should a Pool be Replastered?

For homes with plastered pools, replastering is a crucial maintenance step to maintain the pool’s aesthetics and offer protection from damage.

A backyard swimming pool gives homeowners the perfect place to spend time with family and friends and get a much-needed respite from the heat. Regular maintenance is an essential aspect of swimming pool ownership that helps maximize the investment. For homes with plastered pools, replastering is a crucial maintenance step to maintain the pool’s aesthetics and offer protection from damage. Failing to replaster a swimming pool can cause the pool surface to decay and result in various structural problems. 

As a rule, a pool needs replastering about every ten years. However, some factors, like temperature changes, improper chemistry, salts and heavy metals, and constant use, can damage the pool plaster, causing it to require replastering sooner than expected. Here are a few signs of wear and tear that signify the need for pool replastering:

Surface stains

Pool plaster can develop stains or get damaged over time due to minerals like copper, iron, salt, and calcium in the water. Stains and discoloration can ruin the overall pool aesthetic and hide minor cracks. Monitor the pool for stains that won’t clean off easily, and consider replastering if there are prevalent stains. Before replastering, determine the source of the stain and resolve the issue to prevent them from reappearing after replastering. 

Flaking or peeling plaster

The plaster peeling along the pool’s floor or steps is known as spalling. It usually arises from low pH or calcium levels in the swimming pool. A clear indicator that a pool should be replastered is when the plaster is peeling or flaking from the pool’s surface. 

Concrete showing through

The plaster on the pool’s concrete shell adds to the visual appeal and creates a waterproof barrier. If there are holes in the plaster surface and patches of darker material like concrete or gunite show through, call a pool professional to apply a new coat of plaster to the swimming pool. While it is possible to patch the areas, it is only a temporary solution, and the pool will eventually require replastering.

Structural cracks

Cracks or blisters on the pool plaster are some apparent signs to replaster the pool. The cracks are easily visible and can resemble a spider’s web or can be large structural cracks. A pool owner should address cracks as soon as possible to prevent lasting damage to the pool. Make sure to fill the cracks before replastering. A pool professional can inspect the cracks and suggest the best way to fix the issue. 

The surface feels rough

Another tell-tale sign that a pool need replastering is when the pool surface feels rough, jagged, or sharp while swimming. If left unrepaired, it can lead to scratches or injuries. A rough pool surface indicates that the plaster is wearing down. Address the issue immediately for a safe and comfortable swimming experience.
