Plaster is white cement plus marble dust with a 7-10 year lifespan, quartz is polymer-modified cement plus colored quartz aggregate with a 15-20 year lifespan, and pebble is fortified Portland cement plus natural pebble aggregate with a 20+ year lifespan. The differences come down to what carries the wear (cement vs aggregate), how the surface holds color over time, and how the finish feels underfoot in your poolscape. For most premium residential builds in South Florida, pebble or quartz is the standard choice today.

This comparison is part of the homeowner’s guide to pool finishes.

What is the difference in materials?

Plaster is marble dust in white cement. Quartz is colored quartz aggregate in polymer-modified cement. Pebble is natural pebble aggregate in fortified Portland cement. The pattern is consistent: as you move from plaster to quartz to pebble, the aggregate becomes more durable and the cement matrix becomes more reinforced. Aggregate quality is the single variable that most affects how long the finish lasts.

What is the difference in lifespan?

Plaster lasts 7 to 10 years, quartz 15 to 20 years, and pebble 20 years or more. These are realistic averages. Workmanship from a factory trained applicator can move a project to the top of its range, just as installation shortcuts or neglected water chemistry can push it below the bottom.

What is the difference in fade resistance?

Plaster has the lowest fade resistance because its color comes from cement and pigment that break down under UV and chemistry. Quartz is moderate. Pebble is highest, especially premium exposed aggregate lines such as the Diamond Brite® Jewels collection, where the color is carried by naturally stable aggregate.

What is the difference in feel underfoot?

Plaster is the smoothest, quartz is smooth, and pebble is textured. None of these should feel sharp when properly installed. The trade-off is comfort versus grip: the textured pebble surface delivers the highest slip resistance, which many homeowners value on steps and shallow shelves.

What is the difference in cost?

Plaster is lowest upfront and pebble is highest upfront. Lifecycle economics typically flip that ranking. Once you account for how many times each finish needs resurfacing over 20 years, the premium aggregate finish often costs less in total while delivering far better durability and fade resistance along the way.

Which finish suits which homeowner?

Plaster fits a shorter hold time, the lowest upfront budget, and a less premium poolscape. Quartz fits homeowners who want a balance of cost and durability with a smoother feel, and Durazzo™ is SGM’s quartz option. Pebble fits a premium poolscape, the longest hold time, and the highest fade resistance, which is where Diamond Brite® and River Rok® lead.

Frequently Asked Questions

Which pool finish is best for South Florida?

Exposed aggregate (pebble) is the most popular premium choice in South Florida because its durability and fade resistance hold up to intense sun and year-round use.

Is quartz finish the same as Diamond Brite®?

No. Quartz finishes such as Durazzo™ use colored quartz in polymer-modified cement. Diamond Brite® is an exposed aggregate finish made with natural colored quartz aggregate and is washed to expose the aggregate at the surface.

Does pebble finish hurt your feet?

A properly installed pebble finish is textured but not sharp. Most homeowners find it comfortable, and the texture adds slip resistance.

Is plaster outdated?

Plaster still has a place where upfront budget drives the decision, but many South Florida builders now treat it as a legacy category in favor of quartz and pebble.
