Pool Resurfacing vs. Replastering: What’s The Difference?

Pool Resurfacing vs. Replastering: What's The Difference?

Pools are a great addition to any property and need regular maintenance to keep them looking their best. Pool resurfacing and replastering are two different processes used to maintain a pool’s appearance, but what is the difference between them?

Pool resurfacing involves applying a new layer of plaster on top of an existing coat. The new layer protects the existing layer and provides a smooth, consistent surface for swimming. Replastering involves stripping away the old plaster and replacing it with a fresh coat of plaster, giving your pool an entirely new look.

Many factors determine which process is best for your pool. Pool resurfacing is the less expensive option and can be completed in a shorter amount of time. Replastering is more costly and takes more time. If an existing pool’s plaster is more sound and durable, the new plaster can be applied over the existing plaster with a specific cleaning process and hydraulic cement and bondcoat. If the existing plaster has heavy delamination, the surface must be removed before the new plaster is installed.

Here, we will explain the differences between pool resurfacing and replastering in greater detail so you can decide which process is suitable for your pool.

What Is Pool Resurfacing?

Pool resurfacing is a process that involves cleaning, prepping, and applying a new finish to the swimming pool's interior surface. The most common finishes used are marcite, plaster, or quartz aggregate. This resurfacing covers the top layer of the existing pool finish.

Benefits of resurfacing include:

  • Increased pool surface longevity
  • More comfortable walking to sit
  • Improved filter efficiency
  • Restored the beauty of the swimming pool's interior 
  • Prevents harsh water chemistry from having direct contact with the pool's fundamental structure

What Is Pool Replastering?

Pool replastering is a process by which the existing plaster in your pool is completely removed. The underlying surface of the pool is then prepared, and new plaster, typically made from marble dust or other materials, is applied over the top. It’s important to note that this isn’t simply resurfacing; the entire plaster layer is removed and replaced.

Benefits of replastering include:

  • Improved reliability over the long term
  • Better bond to the structure of the pool
  • Will not be compromised with the durability of any underlying surface
  • Not forced to rely on the preparation made by the company that applied the initial surface.

Factors That Help Determine Which Option Is Best

When it comes to resurfacing or replastering a pool, several factors can help decide which option is best. These include:

1) Cost:

Resurfacing is usually more cost-effective than replastering because it does not require the removal of existing plaster. However, there may be unexpected costs for repairs that need to be done before resurfacing can begin.

2) Appearance:

Replastering will give you a new finish and color if you want a new look for your pool. Resurfacing can also provide an attractive new look but may need help to cover up existing damage or stains and replastering.

3) Durability:

Since the preparation for the existing plaster is unknown, you can be assured that the new plaster has been thoroughly prepped with good cleaning and acid-washing and the proper application of bondcoat and hydraulic cement. Replastering will also ensure that the new plaster is protected from future delamination of the older plaster.

4) Maintenance:

Resurfaced or replastered pools can last a long time with proper maintenance.

Pool resurfacing and replastering are popular options for restoring an old pool to its original condition, but they have some key differences.
