When you resurface a pool, the finish is the one decision you will live with every day. Plaster, quartz and pebble feel different, cost different amounts, and handle stains differently. In a warm, humid place like Macon, stains and algae are real concerns, so this guide compares the three with that in mind.
Why Macon's weather matters
The National Park Service describes Macon's climate as humid subtropical. Its Ocmulgee Mounds weather page says July highs average roughly 82 to 91 degrees, that humidity can push the heat index above 100 degrees, that the city averages about 4.8 days a year at 100 degrees or higher, and that annual precipitation is about 45.7 inches.
Warm water, a lot of rain and long swim seasons are all things algae likes. Rain also carries leaves and organic material into the pool. We found no source that measures algae rates in Macon pools, so we make no claim about how much worse it is here. What the finish sources do say is that porous surfaces give algae and stains more to hold on to, and that is why humid-climate owners compare finishes.
The three finishes
Plaster. Traditional plaster, which some builders call marcite, is white cement and marble dust. One pool company comparison calls it the most vulnerable of the three to staining, etching and erosion from chemical imbalance, with a lifespan of roughly 8 to 12 years if the water is well maintained. White or dyed plaster shows streaks and fading more easily. It is the lowest-cost option and feels smooth. A Macon pool company describes classic plaster as comfortable underfoot, cost-effective and simple to maintain.
Quartz aggregate. Quartz finishes mix plaster with silica and quartz granules, often with colored pigments. The same comparison calls them nonporous and stain resistant, harder, and better at resisting erosion from chemical swings than plaster. The speckled look hides mild stains and etching. It estimates a lifespan well beyond plain plaster and a price about 20 to 30 percent higher. The local Macon company describes quartz as durable, with a refined look and better resistance to discoloration.
Pebble. Pebble finishes mix plaster with small stones. The comparison describes them as highly resistant to chipping, mottling, staining and fading, with a stone-like appearance, a price about 45 to 60 percent above plaster and a more labor-intensive install. The tradeoff is texture. The same source says pebble can feel rough on bare skin depending on the pebble size. The local company describes pebble as having a distinctive appearance and stronger resistance to chemicals and stains. One finish-maker article puts pebble's good looks at about 12 to 14 years, so lifespan figures for it vary by source.
Side by side
| Plaster | Quartz | Pebble | |
|---|---|---|---|
| Upfront cost | Lowest | Middle | Highest |
| Stain and chemical resistance | Most vulnerable | Better | Described as highest |
| Feel underfoot | Smooth | Smooth, speckled | Can feel rough |
| Hides mild stains | Least | Somewhat | Not stated in the source |
| Rough lifespan in a national cost guide | 7 to 10 years | 10 to 15 years | 15 to 25 years |
Lifespans and prices differ by source, and all of these are general numbers. A different cost guide says plaster lasts about 10 years when correctly installed and quartz about 12. Treat the table as an order of the choices, not a promise.
What no finish fixes
Mottling, rough spots, scale and algae in a new finish are often tied to installation and water chemistry, not just the material. One plaster problems guide says mottling can affect all types of plaster finish and is mostly a cosmetic issue, with causes that include troweling problems and water balance. It also says new plaster is especially open to algae if the walls are not brushed enough in the first two weeks. So whichever finish you pick, the start-up period matters, and so does the crew.
A finish also does not replace filtration. In a humid climate, good circulation, regular brushing and consistent sanitizer levels do most of the work against algae. Ask your pool service about a routine that suits your pool.
Choosing for your pool
These questions help you decide between the three.
- How long will you own the house? If you plan to sell in a few years, a lower-cost finish may make sense. If you plan to stay, a longer-lived aggregate may cost less per year.
- Who swims? If young kids or anyone with sensitive feet uses the pool, ask to feel samples. Texture varies by product and pebble size.
- How much upkeep do you want? Plaster asks the most from your water chemistry. Aggregates are described as more forgiving, not carefree.
- What does the shell need first? If the pool has cracks or hollow spots, repairs come before any finish.
- What is the budget? Get a quote for each finish from each provider so you can compare apples to apples. Our cost guide lists the national ranges.
Ask the provider
- Which finish and brand will you use, and can I see a sample?
- How is it applied and who does the work?
- What does the warranty cover for stains, mottling and rough spots?
- What start-up care do you handle and what do I do?
Chemical safety
Start-up and algae treatment mean handling chlorine, acid and other chemicals. Leave products in the containers they came in, keep them cool and dry, and never combine two of them. Never mix chlorine and acid, because together they can release a toxic gas. Follow the label, and check with a pool professional before making big changes to the water.

Common questions
Which pool finish resists algae best?
Sources describe plain plaster as the most porous and stain-prone, and pebble as the most stain resistant. Algae also depends on filtration, circulation and water balance, so no finish prevents it.
Is pebble hard on bare feet?
Several sources say pebble can feel rough on bare skin depending on pebble size. Ask to feel a sample, especially if children or older swimmers use the pool.
Does a darker finish hide stains?
One source says speckled quartz finishes can hide mild stains and etching better than plain white plaster, and that white or dyed plaster shows streaks and fading more easily.
Do aggregate finishes need less chemistry care?
They are described as more resistant to chemical swings, but every finish needs balanced water and a careful start-up.
