How to Know When Your Pool Needs Replastering
Your pool’s plaster serves as a protective layer that keeps the underlying structure safe while providing a smooth, attractive surface. Over time, exposure to chemicals, water, and weather can cause it to wear down. If you’re wondering whether it’s time to replaster your pool, here are some clear signs to look out for.
Rough or Pitted Surface
If the once-smooth surface of your pool now feels rough to the touch or is irritating to your feet, the plaster is likely deteriorating. Rough patches can lead to discomfort and may even cause small cuts or scrapes.
Stains That Won’t Go Away
Discoloration or persistent stains—especially those that don’t come off with scrubbing—can indicate that your pool plaster is aging. Mineral deposits, algae buildup, and chemical imbalances can contribute to deep stains that detract from your pool’s appearance.
Chipping, Flaking, or Peeling (Spalling)
If you notice pieces of plaster breaking off or peeling, this is a sign that the surface is breaking down. This is especially common around steps and ledges, where water chemistry fluctuations are more pronounced.
Exposed Gunite or Concrete
When the plaster wears down enough to expose the gunite or concrete beneath, it’s time to replaster immediately. Exposed gunite can lead to structural damage if left untreated.
Increased Water Absorption
Old plaster becomes more porous, leading to increased water absorption and higher water loss. If you find yourself frequently refilling your pool without an obvious leak, deteriorating plaster could be the culprit.
