When to Resurface Your Pool: Signs, Costs & Options

What is pool resurfacing?

Resurfacing means removing the pool's old interior finish and applying a new one. Chemicals, UV and normal wear break down every pool finish over time, and South Florida's sun and warm water tend to speed that up. EDX Pools handles pool resurfacing across Palm Beach and Broward counties, including interior refinishing with Florida Stucco colors, Diamond Brite quartz and pebble.

Signs you need to resurface

Rough or abrasive surface

If the surface feels gritty like sandpaper, it has worn down. It can scrape skin and swimsuits and harbor algae.

Stains that will not come out

Brown or rust stains from iron, blue-green copper stains and dark organic stains that do not respond to proper treatment mean the finish has absorbed minerals or organics.

Crazing and cracking

Fine hairline cracks are a sign of age. A few small ones may be cosmetic. Widespread crazing means the finish is failing, and larger cracks may point to a problem in the shell that needs an inspection.

Delamination

If plaster is peeling, flaking or sounds hollow when tapped, it is separating from the shell. This needs prompt attention.

Fading and discoloration

Blotchy, dull or patchy color is a sign the finish is near the end.

Algae that keeps returning

A rough, porous finish gives algae places to hide. If algae returns even with good chemistry, the surface may be the cause. See why pools turn green.

Finish options

Lifespan and cost depend on the product, the installer and how well the water is balanced. Here is how they generally compare:

• White plaster: The lowest cost and the shortest life.
• Quartz (such as Diamond Brite): Mid-range cost, more durable, many colors.
• Pebble: A longer-lasting, natural look with more texture. Coarser pebbles can be rough on bare feet.
• Glass bead: The premium tier, with a shimmering look and smooth feel.

Our pool plaster guide compares the options in more detail. Your final price depends on pool size, the condition of the shell, any tile or coping work and the finish you pick. EDX gives a free, itemized estimate on site.

What the work involves

Timing depends on the pool and the weather, but resurfacing generally takes about a week or two of work, followed by a longer curing period. The usual sequence:

• Drain and prepare: The pool is drained, and repairs to the shell, plumbing or tile are made. In areas with a high water table, a pool should not be drained without checking groundwater, because an empty pool can be pushed up by groundwater pressure. Many pools have a hydrostatic relief valve.
• Remove the old finish: The old surface is chipped or stripped to the shell.
• Prepare and tile: A bond coat goes on, and waterline tile is replaced if needed. See pool tile and coping.
• Apply the new finish: The finish is applied and troweled smooth in one continuous session.
• Fill: The pool is filled without stopping mid-fill.
• Start-up: The chemistry is balanced and the surface brushed on a schedule. EDX includes a fire-up with balancing and brushing in its renovation scopes.

Leak repairs, hidden shell damage and deck drainage are common reasons a resurfacing project expands. If you suspect a leak, have it checked first. See pool leak detection.

Caring for the new surface

The first weeks matter. Follow your installer's start-up instructions, and as a general guide:

• Brush the surface on the schedule your installer gives you.
• Test and adjust water chemistry often during the first month.
• Hold off on automatic cleaners until your installer says it is OK.
• Do not drain or partly drain the pool while the finish cures.
• Keep chemistry within the target ranges your installer recommends, including pH and calcium hardness.
