Pool Replastering and Repair: Everything You Need to Know

A swimming pool is one of the most rewarding features a homeowner can haveoffering beauty, recreation, and value. However, over time, even the best-built pools begin to show signs of wear and tear. Cracks, discoloration, rough surfaces, and leaks not only affect the pools appearance but also its safety and performance. Thats where pool replastering and repair comes into play.

In this in-depth guide, well explore the key aspects of pool replastering, the signs that indicate your pool needs attention, repair options available, and how to choose the right professionals for the job.

What Is Pool Replastering?

Pool replastering is the process of removing the old, deteriorated surface layer of a pool and applying a fresh coat of plaster. The plaster acts as the final waterproof layer on concrete or gunite pools and provides a smooth, attractive finish.

Over time, pool replastering and repair can erode due to chemicals, weather, and general use, leading to a rough texture, stains, or structural issues. Replastering restores the pools integrity, appearance, and comfort.

Signs Your Pool Needs Replastering

It can be easy to miss early warning signs if you dont know what to look for. Here are the most common indicators that your pool may need replastering:

Rough Texture

If your pool surface feels like sandpaper underfoot, its likely that the plaster has worn thin and is beginning to deteriorate.

Discoloration and Stains

Stains from minerals, algae, or improper chemical balance can cause unsightly discoloration. If stains become deep-set and unresponsive to cleaning, replastering may be necessary.

Cracks in the Plaster

Fine, hairline cracks are common with aging plaster. Larger cracks, however, can lead to leaks and structural problems if not addressed.

Peeling or Flaking (Spalling)

Sections of plaster may begin to peel or flake away, especially near the surface or around steps. This is a clear sign that the surface is failing.

Persistent Algae Growth

If algae consistently return after cleaning and balancing the water, the porous and deteriorated plaster may be contributing to the problem.

Benefits of Pool Replastering

Replastering not only restores your pools beauty but also extends its life and improves overall safety and usability.

Aesthetic Renewal

A fresh layer of plaster revives your pools appearance, making it look brand new. Many homeowners choose to upgrade to colored or quartz-finish plasters for a more luxurious look.

Improved Comfort and Safety

Worn or rough surfaces can cause abrasions and discomfort. A smooth, replastered pool feels better underfoot and reduces the risk of injury.

Enhanced Durability

New plaster provides a stronger waterproof seal, protecting the underlying structure and preventing leaks.

Increased Property Value

An attractive, well-maintained pool adds to your homes curb appeal and resale value.

Pool Repair: Beyond Replastering

While replastering addresses surface wear, other repairs may be required before or during the process. Common pool repairs include:

Crack Repair

Structural cracks in concrete or gunite pools must be patched using specialized epoxy or hydraulic cement before replastering.

Tile and Coping Repair

Tiles around the pools edge or coping (the material capping the pool wall) may become loose, chipped, or damaged and often need replacement during a resurfacing project.

Leak Detection and Repair

Leaks can develop in plumbing, fittings, or through the shell itself. Professionals use pressure testing and dye tests to locate and fix leaks.

Skimmer and Drain Repair

Skimmers, returns, and main drains often suffer from wear or clogging and may need sealing or replacement during major repair work.

Pool Replastering Process: Step by Step

Understanding the process helps you prepare for what to expect. A standard replastering job typically includes:

raining the Pool

All water is drained, and safety measures are put in place to prevent structural damage from groundwater pressure.

Surface Preparation

The old plaster is chiseled or sandblasted away. Any cracks or damaged areas are patched, and the surface is cleaned thoroughly.

Bonding Coat Application

A bonding agent is applied to ensure the new plaster adheres properly to the existing surface.

Plaster Application

The new plaster (traditional white, colored, quartz, or pebble) is applied smoothly and evenly across all surfaces.

Curing and Filling

After setting, the pool is refilled gradually. Water must be balanced properly in the first week to allow the plaster to cure without damage.

Brushing and Chemical Balancing

The new plaster must be brushed regularly during the first few weeks to remove dust and prevent mottling. Water chemistry is closely monitored.

Types of Pool Plaster Finishes

Modern homeowners have several options beyond the traditional white plaster:

White Plaster

Classic and economical but may show stains more easily over time.

Colored Plaster

Tinted for a unique lookoften blue, gray, or tanto match the aesthetic of your outdoor space.

Quartz Finish

A blend of plaster and quartz aggregate for added durability, shine, and resistance to staining.

Pebble Finish

Long-lasting and slip-resistant, made from natural stone pebbles. Offers texture and an upscale look, though it may cost more.

How Often Should You Replaster Your Pool?

The frequency of replastering depends on several factors including pool usage, maintenance habits, and local climate. Generally:

• Standard plaster: 710 years
  
  

• Quartz or pebble finishes: 1520 years
  
  

Regular cleaning, proper chemical balancing, and prompt repairs will extend the life of any surface.

Cost of Pool Replastering and Repair

Costs vary based on pool size, surface type, and scope of repairs. As a general estimate:

• Replastering only: $4,000$10,000 for an average residential pool
  
  

• Upgraded finishes: Add $1,000$5,000 depending on the material
  
  

• Additional repairs: Tile, coping, and leak repairs can increase overall cost by several thousand dollars
