Marble Dusting Gunite Swimming Pool on Long Island in Cedarhurst NY


Marble dusting is a smooth plaster finish applied to the gunite pool or spa. It’s a mixture of highly refined white cement and crushed marble. This material can be dyed into many colors or purchased in a specific color and aggregate pattern. While white, or anything in the gray spectrum including black is common, exposed aggregate finishes can provide a unique look to your pool.

The marble dust is applied up to the water line followed by rows of tile of your choice. The marble dust and tile offer an attractive finish to your Gunite Pool and Spa Scape.

The 3 Most Common Pool Surface Types

  1. Plaster – Generally, new gunite pools are coated with pool plaster, which is cement mixed with marble sand or limestone. It is the least expensive option for pool surfacing and typically lasts around 7 years.
  2. Pebble – Pebble finishes as a pool surface are just plaster with aggregate mixed in. The addition of aggregate makes this more durable and stain-resistant than plaster alone. Pebble finishes can be somewhat rough and cost twice as much as plaster, but the upside is that they often last over 12 years.
  3. Quartz – A quartz-finished pool surface has plaster with quartz aggregate mixed in. This provides more color than pebbles and is a more stain-resistant option for your pool. A quartz finish will usually last 12-15 years.



A lot of planning, material choice, and effort goes into building a swimming pool. But regardless of the pool’s decorative features and design, pool finishes will transcend the complete design and play a huge role in how appealing the pool is.

Whether you want to resurface your existing pool’s plaster or select the finish for a new pool, you should determine what type of material to use. Pool finishes come with their own set of benefits and drawbacks in areas like durability, visual appeal, and cost.

Your pool’s surface may develop stains, etching, cracks, or other issues over time. And that is entirely normal.

With the wear and tear of pool plastering, the beauty of your pool reduces along with its durability. That means it requires a fresh coat finish before the conditions worsen.

Plaster is the most visible element of your poolscape. It creates a protective layer between the pool surface and pool water to avoid water leakages that may damage the structural shell. The interior plaster finish is also crucial to its integrity. Hence, make sure you maintain it properly to ensure the longevity of your pool.

When to Resurface Your Pool

Pool resurfacing is a must-do treatment to keep the pool running smooth and looking as beautiful as the first day you saw it. There are tons of ways to resurface a pool, mainly depending on the type of surface of your pool – tile, plaster, pebble, cement, quartz, etc.

On average, pools need resurfacing every eight to 10 years. But, if you notice some of these signs, it might be time for maintenance:

  • Surface stains
  • Plaster is flaking or peeling
  • Coarse texture
  • Cracks
  • Discoloration
  • Rust stains
  • Loss of pebbles
  • Paint or fiberglass failure

Pool Plastering is the final layer of polish or interior pool finish that makes a pool’s interior visually appealing. Along with its aesthetic purpose, the coating smoothens and balances out the roughness of the concrete below it.  Marble dust, adds a smooth plaster finish that is applied to the gunite pool or spa. It’s a mixture of highly refined white cement and crushed marble. This material can be dyed into many colors or purchased in a specific color and aggregate pattern.

What is the Duration of Pool Plaster? 

Depending on a variety of factors and how well you maintain your pool, your plaster can last from 7 to 10 years. The average life expectancy of a plastered pool is affected by regular pool maintenance and cleaning. If you take excellent care of pool plaster, such as maracite plaster can last up to 7-10 years while you’ll get an additional five years on the life of your pool if you use quartz aggregate blend for pool plastering.

How Long Should I Wait Before Using the Pool After Plastering?

Unlike ordinary plaster which needs to dry completely first, pool plaster works differently. Once the plaster dries out; fill the pool with water. The plaster material cures underwater in about 7-10 days. But this doesn’t mean you have to wait that long. Once the pool is filled and clean, you can go in for a swim.

How do I get rid of plaster dust in my pool?

Brush the entire pool surface.  Start at the top of the walls and go down from the shallow end of the pool’s deep end.  Brush thoroughly twice per day to remove all plaster dust. Brushing your pool finish at least twice a day is one of the best things you can do to maintain the gorgeous appearance of a pool finish.
