Why replaster your pool? In a world styles are constantly changing, pool plasters are no exception. No longer are pool’s surfaces being plastered in plain old white. Pool plastering companies are now offering colored additives—even colored aggregates! —to add visual interest and greater durability. As a trend-conscious customer, you’ll be sure to find an option that satisfies you.

What Is Pool Plaster?

The ingredients of pool plaster are simply a 1:2 ratio of white portland cement and marble dust. The two components are mixed together with water and bonding additives, sprayed on the prepared surface, and smoothed over. Typically, the final product is a clean, white, reliable surface.

For those looking for a little extra pizazz, there are several options that can be added to the standard mix to liven up the look of your pool’s surface.

Types of Additives


Adding colorants to the mix can dye pool plaster any color. Lamp Black dye can produce different shades of gray to black. Different hues of red and blue can also be easily achieved. The one drawback of colored plaster is the variation in hues that can occur. Nevertheless, adding color to your pool’s plaster can yield dramatic effects. Expect “wow’s” from friends and families with this choice.


Colored quartz chips can be added to the mix to produce an element of visual interest. Not to mention, the durable quality of quartz will make your plaster more chemical resistant, immediately adding to the value of your pool plaster. The specks of colors created by the quartz can hide dirt, debris, or other surface imperfections. And don’t be worried about the texture, these additives are flat and smooth and you can expect the finished surface to feel likewise.


This additive does not change the color or texture of your plaster. Instead it adds value by preserving the plaster from etching and mottling. It traps calcium hydroxide, which results in a smoother, longer lasting finish.

Silicone Shield

Looking for another protective additive? Silicone Shield will “waterproof” your plaster, resulting in less staining and lowered chances of chemical deterioration.

Other Surface Options: Exposed Aggregates


Pea gravel sized river pebbles can be added to the plaster mix, and after application, a thin top layer is removed to expose the tiny, colored pebbles. This is a great option if you’re looking to install a beach front entry and don’t want waterline stains. There are other pebble products to choose from, but the overall look and feel is the same. Though slightly more “bumpy” than other options, these pebbles typically last much longer than the normal pool plaster.


This product is composed of tiny glass beads set in a polymer modified mortar. This is a dazzling finish that is reflective and slip resistant. This option is typically more durable than traditional white plaster, as well.

When Should a Pool Be Replastered?

With so many options for looks and finishes, you might be concerned, (or hoping), it’s time your pool is replastered.

Pool plaster can last many years before the erosive effects of water and chemicals begin to degrade the surface. You’ll know it is too old when the surface becomes rough and stains become harder to remove. It is meant to degrade very slowly, although many factors can affect its appearance and surface softness.

But at the end of the day, replastering your pool is done primarily for aesthetic reasons. With all the options listed above, your inner designer will be sure to find something that leaves you with a stunning, new-surfaced pool.
