What Is Pool Plastering?
Pool plastering is the process of applying a waterproof, smooth interior coating to the shell of a swimming pool. This finish layer is what you see and feel when you touch the pool's walls and floor. It serves both aesthetic and functional purposes — creating a watertight seal while giving your pool its color and texture.
Over time, pool plaster naturally wears down due to chemical exposure, water conditions, and physical use. Most pool plaster lasts between 7 and 15 years depending on the finish type, water chemistry maintenance, and environmental factors.
Types of Pool Plaster Finishes
Modern pool plastering offers several finish options, each with different characteristics, aesthetics, and longevity:
- Standard Plaster — The classic choice. White or colored plaster provides a smooth finish at the most affordable price point. Expect 5-10 years of life with proper water chemistry.
- Quartz — Quartz aggregate mixed into the plaster creates a more durable surface with a subtle shimmer. Available in multiple colors with enhanced stain resistance.
- Mini Pebble — Small natural pebble aggregates create an extremely durable surface with beautiful water color variations. A dependable classic finish with an excellent balance of durability and beauty.
- Micro Pebble — Even finer pebble aggregate for a smoother feel underfoot while maintaining the durability benefits of pebble finishes.
- Polished Marble — The luxury option. Polished marble aggregate creates a glass-like smooth surface that is both stunning and incredibly long-lasting.
The Pool Plastering Process
Professional pool plastering follows a careful, multi-step process:
- Drain and Prep — The pool is fully drained and the existing surface is prepared. This includes surface preparation and bond coat application to ensure the new plaster adheres properly.
- Tile and Coping — If needed, waterline tile and coping are replaced or repaired before plastering begins.
- Plaster Application — The plaster crew applies the chosen finish material in a single, continuous session. This is critical — stopping and starting creates visible seam lines.
- Fill and Balance — The pool is immediately filled with water after plastering. Once full, water chemistry is carefully balanced to protect the new finish during its curing period.
How Much Does Pool Plastering Cost?
Pool plastering costs vary based on two main factors: your pool's perimeter measurement (in linear feet) and the finish tier you select. At Golden Pools, our pricing ranges from $89 per linear foot for Standard Plaster up to $215 per linear foot for Polished Marble.
For a typical residential pool with an 80-90 foot perimeter, total plastering costs typically range from about $7,000 to $19,000+ depending on the finish selected. Additional costs may include pool prep and demo ($41/ft) and tile replacement ($34/ft) if needed.
When Should You Replaster?
Watch for these signs that it's time to replaster your pool:
- Visible staining that won't respond to chemical treatment
- Rough or peeling plaster surface
- Exposed aggregate or gunite beneath the plaster
- Persistent water chemistry problems
- Your pool is over 10 years old with the original plaster
Choosing the Right Finish
The right finish depends on your budget, aesthetic preferences, and how long you want the finish to last. Standard plaster is ideal for budget-conscious pool owners, while mini pebble offers the best balance of price and longevity. For the ultimate luxury upgrade, polished marble delivers an unmatched smooth, glass-like surface backed by the longest warranties available.
