EcoFinish and plaster are not two versions of the same surface. EcoFinish aquaBRIGHT is a thermoplastic coating applied over a properly prepared concrete/gunite pool. Marcite, quartz, pebble, polished aggregate and many glass-bead finishes are cementitious systems. Matt likes all of them for different reasons, but for many long-term owners he prefers EcoFinish because, in his words, “I really don’t have a problem with any of these finishes. They all have pros and cons. I just think EcoFinish has fewer cons.”
First: what do homeowners mean by “plaster”?
Homeowners often use the word plaster for almost every masonry pool interior. For a useful comparison, Matt separates the major cementitious finish families:
The classic hard-troweled cementitious finish. It can be very smooth when new and is usually the lower-cost starting point.
A cementitious finish using quartz aggregate for additional color, texture and durability compared with plain marcite.
A cementitious matrix exposing natural or manufactured aggregate. It creates a durable, textured appearance that many homeowners like.
A premium cementitious finish that is mechanically polished after installation for a much smoother, more refined feel.
Premium cementitious systems incorporating glass beads for sparkle and visual depth. Product systems differ by manufacturer.
A thermoplastic aquatic coating. It is not a cementitious plaster finish and uses a different preparation and application process.
EcoFinish vs. the major plaster families
| Finish family | What homeowners usually like | Matt's main tradeoff to discuss | Relative cost* |
|---|---|---|---|
| Traditional marcite | Smooth when new; simple, classic appearance; lowest starting cost. | Matt sees it become rougher sooner than premium options when chemistry, etching, scale and age affect the surface. | $ |
| Quartz | More color and aggregate than standard plaster; good middle-ground option. | Still a cementitious surface, so long-term feel and appearance depend heavily on chemistry, installation and aging. | $$ |
| Pebble | Natural texture, visual depth and a high-end aggregate look. | Texture can be too rough for some swimmers; aggregate size and finishing technique matter. | $$$ |
| Polished aggregate / marble | Luxury appearance with a smooth polished feel. | Higher cost; the surface can eventually need repolishing. Matt considers sound polished finishes good candidates for future repolishing. | $$$$ |
| Glass bead | Sparkle, color depth and a distinctive premium appearance. | Higher material and installation cost; application quality and mix consistency matter. | $$$$ |
| EcoFinish aquaBRIGHT | Very smooth feel, broad color choices, no traditional plaster startup, and a non-cementitious surface. | Highly installer-dependent. Prep and application quality matter enormously, and a cheap or inexperienced crew can create preventable problems. | $$$$ |
*Relative-cost key: Matt's planning tiers, not a quote. Pool size, demolition, prep, geometry, product choice and local labor/material costs can move any project up or down.
The biggest difference: cementitious surface vs. thermoplastic coating
Traditional plaster, quartz, pebble, polished aggregate and glass-bead systems rely on cementitious material and aggregate. Their appearance and feel can change as the cement matrix is exposed to water chemistry, scale, etching and normal aging.
EcoFinish aquaBRIGHT is a thermoplastic coating. ecoFINISH states that aquaBRIGHT does not require the aggressive startup used by some colored masonry finishes and markets its startup as “Balance and Swim.” The manufacturer also offers a special slip-resistant application process for steps, benches, beach entries and other high-traffic aquatic areas.
Smoothness: day one is not the whole story
Traditional marcite can be one of the smoothest surfaces in a brand-new pool. Matt's concern is what the surface feels like years later. In his field ranking, EcoFinish is #1 for long-term smoothness, polished aggregate / polished marble is #2, and traditional marcite is #3 overall because marcite typically becomes rougher sooner.

Appearance: plaster families still have advantages
EcoFinish is not automatically the winner if the homeowner wants a specific visual effect. A polished marble finish can have a depth and stone-like luxury that a coating does not try to imitate. Pebble gives a natural exposed-aggregate appearance. Glass-bead finishes add sparkle and reflected light. Quartz can provide a traditional pool look with more color and aggregate than plain plaster.
A lot of manufacturers sell very similar types of finishes under different brand names. Matt tells homeowners to understand the finish family first instead of getting lost in sample-board marketing. In his experience, the brand getting the most attention is often the one with the best-looking samples—not necessarily the only product capable of creating that type of pool.
Installer quality matters with every finish—and especially with EcoFinish
“With EcoFinish, the crew matters.” Matt believes experienced applicators need to care about the finished result, be paid to do the work correctly and be accountable for fixing mistakes. In his experience, putting inexperienced people on EcoFinish jobs, paying them cheaply and selling the installation mainly on price is when application problems become much more likely.
The same principle applies to cementitious finishes. Troweling, exposing aggregate, polishing, batching, mixing and startup all affect the finished result. The product name cannot compensate for poor installation.
Maintenance and chemistry
No pool finish eliminates water-care responsibility. Cementitious finishes can be affected by aggressive or scale-forming water, while EcoFinish still requires balanced water and normal pool maintenance. Matt's point is not that EcoFinish makes chemistry irrelevant—it is that the finish itself is not a curing cement surface.
Which one would Matt put in his own pool?
EcoFinish. That is his personal preference after years of applying and maintaining different finish types. But he does not treat that preference as a reason to push every customer into the same product.
“I will always talk a customer out of doing something that I think is a waste of money, and I’ll always give them my best professional advice on installing a product or a pool finish or anything, not just to make money, but for their best interest.”
When Matt would still recommend a plaster-family finish
- Traditional marcite: when the homeowner prioritizes a lower initial cost and likes a classic smooth finish.
- Quartz: when the homeowner wants a step up in appearance and aggregate without moving into the highest-cost finish categories.
- Pebble: when a natural, textured, exposed-aggregate look is the priority.
- Polished aggregate: when the homeowner wants one of the most luxurious cementitious surfaces and values a very smooth polished feel.
- Glass bead: when sparkle and a jewel-like premium appearance are more important than keeping cost down.

Frequently asked questions
Is EcoFinish the same thing as plaster?
No. aquaBRIGHT is a thermoplastic coating system for prepared concrete/gunite pools. Traditional plaster, quartz, pebble, polished aggregate and many glass-bead interiors are cementitious finish systems.
Does 'plaster' include quartz and pebble?
Homeowners often use 'plaster' broadly. Technically, traditional marcite is one finish type, while quartz, pebble, polished aggregate and many glass-bead finishes are different cementitious pool-finish families.
Which is smoother, EcoFinish or plaster?
Matt ranks EcoFinish highest for long-term smoothness in his field experience. Traditional marcite can be extremely smooth when new, while polished aggregate can also be very smooth and may be repolished when the underlying finish remains sound.
Is EcoFinish always the best choice?
No. Matt says every finish family has pros and cons. He often prefers EcoFinish for long-term ownership, but a homeowner may reasonably choose plaster, quartz, pebble, polished aggregate or glass bead for budget, texture or appearance.
