The Complete Guide to Pool Plaster: Types, Costs & Lifespan

Why your pool finish matters

The interior finish affects how the water looks, how the surface feels underfoot, how well it resists stains and how soon you will need to resurface. South Florida pools get year-round use, strong UV and warm water, which are hard on any finish.

Price ranges below are general industry guidance. They vary with pool size, condition of the shell and the product you choose. EDX Pools quotes pool resurfacing free on site, and the estimate is itemized so you can see what each choice adds.

Types of pool finishes

White plaster (marcite)

Traditional white plaster is a hand-troweled mix of white cement, marble dust and water. It gives the water a classic light blue look.

• Cost: Typically the lowest of the common options.
• Lifespan: Typically the shortest of the common options.
• Pros: Lowest cost, classic look, smooth feel.
• Cons: More prone to staining and etching, and can roughen as it ages.

Quartz aggregate

Quartz finishes, such as Diamond Brite, blend colored quartz with white cement. They are more durable and more stain resistant than plain plaster, and they add depth to the water color.

• Cost: Typically mid-range.
• Lifespan: Typically longer than plain plaster.
• Pros: Wide color range, better durability, good stain resistance.
• Cons: Slightly rougher than plain plaster.

Pebble finishes

Pebble finishes mix small river stones into the cement for a durable, natural look. Texture varies by product: larger pebbles feel more textured, smaller or finer aggregates feel smoother underfoot.

• Cost: Typically higher than quartz.
• Lifespan: Typically among the longest.
• Pros: Excellent stain and chemical resistance, natural appearance, many colors.
• Cons: Higher cost, and coarser pebbles can be rough on bare feet. Installer experience matters.

Glass-bead finishes

Glass-bead finishes use small glass beads for a shimmering look in sunlight. They tend to feel smooth and are at the premium end of the range.

• Cost: Typically the highest.
• Pros: Striking appearance, smooth feel, durable.
• Cons: Cost, and a more limited color range than pebble in some product lines.

In our work, we have used Florida Stucco colors such as Sky Blue, Azure and Capri, as well as Diamond Brite quartz and pebble finishes. Ask to see physical samples before you decide, because photos and screens rarely match the color in your pool.

How color changes the water

• White and light finishes: Bright, classic light blue water.
• Blue and blue-green finishes: A deeper, more tropical blue.
• Dark finishes: A reflective, dramatic look. They absorb more heat, which can warm the water a few degrees.
• Earth tones: A natural lagoon look that suits freeform pools.

Signs you need to resurface

• Rough texture: The surface feels like sandpaper because the smooth cement layer has worn away.
• Stains: Persistent stains that do not respond to proper treatment.
• Spalling or chipping: Pieces flaking off and exposing the shell.
• Chalking: White, powdery residue that clouds the water.
• Cracks: Surface cracks that collect algae. Some cracks point to a deeper problem, so have them checked.
• Fading: Large areas of lost color.

Our guide to when to resurface your pool goes deeper on timing and what the work involves. If you are also tired of cracked tile, ask us about pool tile and coping in the same visit.

Helping your finish last

Water chemistry is the biggest factor in how long any finish lasts. Ask your pool professional for target ranges for your pool, and keep these habits:

• Test regularly and keep pH, alkalinity and calcium hardness in balance.
• Keep the stabilizer (cyanuric acid) in range so chlorine is protected from UV.
• Do not leave the pool without circulation for long periods.
• Treat stains early, before they set.
• Follow a proper start-up routine on new plaster. Early brushing and chemical balancing matter. EDX includes start-up, balancing and brushing after a new finish in renovation scopes.
