Over time, your pool’s plaster surface wears down due to water chemistry, weather, and constant use. If left unchecked, deteriorating plaster can lead to structural damage, water loss, and an unpleasant swimming experience.
How do you know when it’s time to replaster your pool? At COCPools.com (Clearwater Outdoor Creations), we specialize in professional pool replastering services to restore your pool’s beauty and longevity.
In this guide, we’ll explore the key signs that indicate your pool needs replastering—and the best time to take action.
✔ Chemical imbalances cause plaster to break down.
✔ Aging plaster naturally erodes over time.
✔ High calcium hardness leads to scaling and rough spots.
⚠ Can scratch skin and swimsuits.
⚠ Creates an ideal surface for algae growth.
⚠ Makes cleaning and maintenance harder.
✔ If small rough patches appear, a light acid wash may help.
✔ If the roughness spreads across the pool, it’s time for a full replastering.
✔ Metal stains from iron, copper, or manganese in the water.
✔ Chemical damage from pH imbalances and chlorine overuse.
✔ Organic stains from leaves, algae, and debris.
⚠ Makes your pool look dirty even when it’s clean.
⚠ Stubborn stains can indicate plaster deterioration.
✔ Try acid washing or stain removers first.
✔ If discoloration persists, plaster has absorbed the stains and needs replacement.
✔ Freezing and thawing cycles cause cracks in the plaster.
✔ Low pH or high chlorine can degrade plaster, causing flaking.
✔ Aging plaster naturally loses adhesion and begins to chip.
⚠ Water can leak through cracks, leading to expensive repairs.
⚠ Flaking plaster can get into pool filters, causing damage.
⚠ Large cracks can indicate deeper structural issues.
✔ Small cracks may be patched temporarily, but larger ones require replastering.
✔ If flaking spreads, it’s time for a full resurfacing.
✔ Cracked or thinning plaster allows water to seep through.
✔ Pool structure shifts over time, causing small leaks.
✔ Poor plaster application leads to early deterioration.
⚠ Increases water bills and chemical usage.
⚠ Can lead to underground damage if ignored.
⚠ Weakens the pool’s structure, requiring major repairs.
✔ Perform a bucket test to determine if the pool is leaking.
✔ If water loss is confirmed, a professional inspection and replastering may be necessary.
✔ Sun exposure and chemical imbalances cause fading.
✔ Over time, pool chemicals slowly wear down plaster layers.
✔ Aged plaster loses its protective coating, exposing the rougher material underneath.
⚠ Can lead to increased algae growth and staining.
⚠ Creates a dull, outdated appearance.
⚠ Exposed material weakens the pool’s surface, making repairs inevitable.
✔ If the fading is minor, repainting or sealing the plaster may help.
✔ If the surface is thin and worn, replastering is the best option.
✔ High calcium hardness leads to deposits.
✔ Poor water circulation causes minerals to settle.
✔ Hard water and evaporation leave behind scale residue.
⚠ Creates unsightly white or chalky streaks.
⚠ Can make pool surfaces rough and difficult to clean.
⚠ Leads to filter and plumbing clogs.
✔ Mild cases can be scrubbed away with a pumice stone.
✔ If scaling is widespread, acid washing or replastering is needed.
✔ Worn-out plaster provides a rough surface where algae cling.
✔ Small cracks or pits in plaster harbor algae, making it difficult to clean.
✔ Chemical imbalances due to plaster breakdown affect water quality.
⚠ Requires excessive chemicals to manage.
⚠ Makes the pool look dirty and uninviting.
⚠ Can indicate widespread plaster damage.
✔ Regular brushing may help, but replastering is the long-term fix.
✔ Choose a smooth, durable finish like PebbleTec for future resurfacing.
Spring and Fall are the best seasons to replaster because:
✅ Temperatures are moderate, allowing plaster to cure properly.
✅ Less evaporation means better adhesion and longevity.
✅ You avoid peak summer demand, which can lead to higher costs.
If you’ve noticed rough surfaces, cracks, leaks, or stains, it’s time to consider replastering your pool. Addressing these issues early prevents further damage and extends your pool’s lifespan.
