Smoother than pebble
Without dropping all the way back to plain plaster.
Quartz Aggregate Finishes
Plaster made harder with crushed quartz. Smoother and less expensive than pebble, with a shorter life, and still the right call in a few specific cases.
What It Is
What is a quartz finish?
A quartz aggregate pool finish is plaster with crushed quartz crystals mixed in instead of the soft marble dust plain plaster uses. Quartz is much harder, so the surface resists etching and staining better and holds its color under sun that fades pigmented plaster. The look is a fine speckle rather than visible stone, and underfoot it sits between plaster and pebble.
We’ll be straight with you: quartz has largely been overtaken. It was a real improvement over plain plaster when it arrived, and pebble has since moved past it on the measure that matters most, which is how long it lasts before you resurface again. On most projects we’ll point you toward pebble instead.
There are still cases where quartz is the right call. On a resurface with a fixed budget it puts a genuinely better surface than plain plaster in the pool for less than pebble. It’s smoother, which matters to some families. And its color range includes vivid blues and teals that are hard to hit in stone. If any of those is your deciding factor, quartz is defensible, and we’ll install it well.

Your options.
Color
White, wide blues and teals, greens, grays, and darker blends. Broader and more vivid than natural stone can offer, since the quartz is coated and colored rather than quarried.
Aggregate density
Standard blends, or richer blends with more quartz per unit. More aggregate means more sparkle, better durability, and more cost. The cheapest blends behave closer to plaster.
Accents
Color-coated quartz or shell added into the mix. Adds luster and visual depth. Accents also add a little texture to an otherwise smooth surface.
Texture
Standard exposure, or a smoother finished surface. Quartz can be finished smoother than pebble, which is much of its appeal for people sensitive to texture.
Why quartz.
Colors stone can’t do
Vivid blues and teals come from coated quartz, not from a quarry.
Harder than marble dust
Real resistance to etching and staining compared with plain plaster.
Costs less than pebble
A genuine option when the budget on a resurface is fixed.
FAQs
The honest tradeoff is lifespan. These are the questions we hear most about quartz.
Is quartz better than pebble?
Smoother and less expensive, yes. Longer-lasting, no: pebble outlasts it by a wide margin. If budget or surface feel is your deciding factor, quartz makes sense. If longevity is, pebble wins clearly.
How long does a quartz finish last?
Published figures vary widely, and water chemistry drives it more than the product does. What every source agrees on is that it’s meaningfully shorter than pebble, commonly around half the service life. On a pool you plan to keep, that’s the difference between resurfacing once and resurfacing twice, and the second job usually costs more than the gap you saved on the first. Ask us for the interval we actually see.
What is bond failure?
Important. The specific risk with quartz, and an installation problem rather than a product one. If the new finish doesn’t key properly into the shell beneath, it can delaminate and lift, sometimes years later, and the repair is a full resurface. Shell preparation decides it.
Can I put quartz over an existing finish?
On a resurface, yes: the old surface is prepared and the new finish applied over it. Preparation quality determines whether it bonds properly, which is the whole ballgame with this product.
Are all quartz finishes the same?
No. “Quartz finish” spans a wide range of aggregate density, and a thin blend performs closer to plain plaster than to the premium product it’s sold as.
Does quartz need special care?
The same care as pebble, for the same reason: the cement binder is what fails, and water that runs acidic or low in calcium attacks it.
What should I ask any builder?
Three things. How is the shell being prepped before the finish goes on? Which blend, specifically, and how much aggregate is in it? What’s your warranty, and what voids it?
