What Is Pool Repair?

What Is Marble Dusting?

Marble dusting—also known as white plastering—is a resurfacing technique used to restore the interior surface of a gunite pool. It involves applying a new layer of marble-based plaster to create a smooth, uniform finish that improves appearance, safety, and longevity.


This process is essential for maintaining the structural integrity of your pool and protecting swimmers from rough, abrasive surfaces. Whether your pool is aging, stained, or deteriorating, marble dusting brings it back to life—both visually and functionally.



We apply high-quality marble dust plaster in white or other available finish tones, offering a clean, bright look that enhances the entire pool area.

We identify and repair any structural cracks or imperfections before applying new plaster.

Application of Marble Dust Finish

Our skilled team applies a smooth, even layer of marble dust plaster, hand-troweled for a professional finish.

Curing & Brushing Schedule

Once filled, the pool undergoes a curing process that includes daily brushing and water chemistry monitoring to ensure a strong, even surface.

Final Inspections & Client Walkthrough

After the plaster has cured, we conduct a full inspection and walk you through proper care for your new finish.

Why Marble Dusting Matters

Marble dusting is more than cosmetic—it plays a critical role in the long-term health and usability of your pool. A clean, smooth interior surface makes maintenance easier, protects swimmers, and prevents water loss or damage to the pool shell.
