Four pool finish samples side by side: white plaster, blue quartz, natural pebble and a glass bead blend

A pool resurfacing quote in Florida arrives full of words that sound like brands, grades and promises at once: plaster, marcite, quartz, pebble, glass bead, polished, exposed, blend. This page is a glossary of those pool finish types written for the homeowner reading the quote, not for the crew applying it. It explains what each finish is made of, how the industry itself groups them, what a contractor’s license class has to do with the work, and which questions turn a vague quote into a clear one. It deliberately leaves out two things every sales page includes: how many years a finish lasts and what it costs. Neither has a source we can stand behind, and both depend on the pool, the water and the care more than on the material. The one subject that does have a published standard, the first 28 days after the new finish goes in, gets its own page.

How the industry groups pool finishes

The trade body for this work is the National Plasterers Council (NPC). Its start-up procedures, which most finish manufacturers reproduce, apply to pools with a plaster interior finish and list the family as marble, quartz, pebble, glass bead, and blends of any of those. That one sentence is the glossary in miniature. Every finish below is a cement-based (the industry word is cementitious) coating troweled or pumped onto the pool shell, and what separates them is the aggregate mixed into the cement: marble, quartz, small stones, glass, or a mix.

The council is also clear about what it is not. Its own disclaimer says the procedures “are advisory and non-binding” and that the council “does not regulate, control, or monitor the acts of its members or others.” In other words, the NPC sets the technical standard; it does not license anyone. Licensing is the state’s job, covered further down.

The pool finish types, one by one

Plaster (marble plaster, marcite, white coat). The original pool finish and the base of the whole family: a cement finish with marble aggregate, the one the NPC’s list calls simply “marble.” It cures smooth and, when white, gives the classic light blue water. Marcite is a trade name that became a generic word for the same thing. When a quote says “standard plaster” or “white plaster,” this is what it means.

Colored or pigmented plaster. The same marble plaster with pigment added. One sourced caution worth knowing: the industry start-up guidance warns that concentrated cyanuric acid, a common stabilizer, can discolor pigmented finishes, which is why start-up chemistry is handled differently on colored pools.

Quartz. A cement finish whose aggregate is quartz rather than marble. Manufacturers sell it under product names; PebbleTec, for example, describes its PebbleQuartz line as “a silica-based quartz finish,” and the distributor NPT groups its own quartz products under the words “silky smooth quartz.” On a quote the words to look for are quartz, quartz aggregate, or a brand name followed by a color.

Pebble (exposed aggregate). A cement finish carrying small natural stones that are left exposed at the surface, so the texture is the stone rather than the cement. The size of the stone is the whole story of the texture. PebbleTec’s own line runs from its original finish, “featuring aggregate made of the largest stones in our line,” through PebbleSheen, “a blend of slightly smaller pebbles,” to PebbleFina, “Made from our smallest natural pebbles,” which the maker calls “the smoothest aggregate finish available.” Other manufacturers make equivalent lines under their own names. When a quote says “pebble,” ask which stone size, because the feel underfoot runs from gravel to fine sand across that range.

Polished aggregate. A pebble or quartz finish that is ground and polished after it cures rather than left exposed. PebbleTec’s PebbleBreeze, for instance, is described as “buff-polished for maximum comfort,” and NPT lists “polished” as its own category. The result is smoother than the same aggregate left rough. If smooth is the priority, this is the word to ask about.

Glass bead. A finish where glass beads are part or all of the aggregate. PebbleBrilliance is a blend of “glass beads and natural stone aggregate,” and PebbleEssence adds “fine glass beads” to a pebble base. NPT’s category is simply “striking glass beads.” The glass is there for color and light; it is still a cement finish and still follows the same 28-day start-up.

Blend. The NPC’s fifth category: any mix of the above, most often pebble with glass bead, or quartz with marble. Manufacturers’ names rarely say “blend,” so when a product name does not tell you what is in it, ask for the aggregate list.

Tile (waterline and full tile). Not a plaster finish at all. Waterline tile is the band of ceramic or glass tile at the top of the wall, usually replaced or reset in the same job as a resurfacing. A fully tiled pool is a different trade and a different quote. Tile work on the pool shell falls under the pool contractor’s scope, and the “trim” specialty exists for exactly this.

Interior finish, interior refinishing. The statute’s words. Florida’s contractor law, s. 489.105(3), does not use “resurfacing”; the commercial and residential pool contractor scopes include “interior finishes,” and the servicing contractor scope includes “interior refinishing.” Your quote says resurfacing; the license behind it says one of these.

Chip-out, prep, bond coat. Steps, not finishes. Chip-out removes failed or hollow areas of the old finish; prep is the surface work before the new coat; a bond coat is a layer applied so the new finish adheres to the old shell. Whether a job needs a full chip-out or a prep-and-bond approach is a judgment about your pool’s condition, and it is the single biggest reason two quotes for the same pool differ. Ask which one you are being quoted, and why.

What a license class has to do with the finish

All three Florida pool contractor classes may apply an interior finish. The Florida Swimming Pool Association’s licensing page describes the commercial class as covering “building, repair, and remodel/resurfacing of any public/commercial or private swimming pool or spa regardless of use,” the residential class as covering residential build, repair, remodel and resurfacing, and the servicing class as covering repair and resurfacing of public and residential pools, with one limit: it “Cannot build a new swimming pool or spa.” So a resurfacing contractor with any of the three classes is properly licensed for the finish. What the servicing class cannot do is change the shell, which matters only if your resurfacing quote also includes adding a spa, a bench or a sun shelf. The companion page on this site walks through the license check itself.

Pool cleaning is the other side of that line. No state license is needed to clean a residential pool, but any repair, or the installation or replacement of equipment, needs a pool contractor license. A finish is a repair.

Reading a resurfacing quote: the questions that matter

Which finish, by aggregate, not just by brand name? Marble, quartz, pebble, glass bead, or a blend. If the answer is a product name, ask what is in it.
What stone size, if pebble? The maker’s range runs from the largest stones to the smallest, and the texture follows.
Exposed or polished? Same aggregate, very different feel.
Chip-out or prep-and-bond, and what decided it? The honest answer references your pool’s condition, not a company policy.
Is the waterline tile replaced, reset, or left alone?
Who does the start-up? The NPC’s 28-day procedure begins on fill day. Some contractors run the first days themselves and hand off; others hand off at the fill. Get the handoff in writing.
Which license class, and the CPC number? Then verify it with DBPR before signing.

Two things this page will not tell you

How long a finish lasts, and what it costs. Lifespan figures on sales pages range so widely that the number says more about the page than the finish, and no manufacturer or trade body publishes a lifespan we could cite. Prices depend on the pool’s size, the prep it needs, the tile, and the market, and a figure on a website is not a quote. Get three written quotes from licensed contractors on your own pool, and compare them with the questions above.

Frequently asked questions

Is quartz a kind of plaster? Yes. In the NPC’s grouping every one of these is a cement-based interior finish; quartz is the version whose aggregate is quartz instead of marble.

Is pebble rougher than plaster? Pebble left exposed is textured by the stone. How rough depends on stone size, and polished versions are ground smooth. The manufacturer’s product descriptions quoted above give the range.

Can a pool service company apply a new finish? If it holds the swimming pool/spa servicing contractor license, yes. The class covers repair and resurfacing; it cannot build a new pool or alter the structure.

Does “resurfacing” appear in Florida’s contractor law? No. The statute uses “interior finishes” and “interior refinishing.” They mean the work your quote calls resurfacing.

What happens in the first month after a new finish? The NPC’s start-up procedure runs 28 days: continuous filtration at the start, brushing twice a day, specific chemistry steps, no salt, no wheeled cleaners and no shocking until the period ends. It has its own page on this site.

Why does the colored plaster come with different chemistry instructions? The industry’s start-up guidance warns that concentrated cyanuric acid can discolor pigmented finishes, so stabilizer is added more carefully on colored pools.
