Your pool’s surface should be kept smooth and clean. However, over time, the surface begins to deteriorate. How often your pool needs to be resurfaced depends on the material it’s made from and other factors such as wear and tear. Cement and plaster pools require resurfacing every 3 to 7 years, while fibreglass pools can last for 15 to 30 years.

A concrete pool usually lasts for 10 to 15 years. Pool resurfacing involves the reinforcement of beams, filling in lines around tiles and the pool skimmer, as well as installing a waterproofing layer between the water and shell of your pool. It’s common to replace the waterline tile in addition to redoing your pool’s surface.

Why Resurface?

Minerals like copper and iron build up in pools over time and can stain the plaster. This can result in damage to the quality and appearance of your pool. Other influences like temperature fluctuations and plaster degradation can have an impact on the deterioration of your pool’s aesthetic or even cause rusting.

There are many benefits to resurfacing your pool. Pool owners may want to consider resurfacing for the following reasons:

  • Improve pool’s appearance
  • Achieve a slip-resistant exterior
  • Increase the value of your property
  • Resurfacing is a cheaper alternative to replacement
  • Improve safety and cleanliness

Signs Your Pool is Due for Resurfacing

No matter what material your pool is made of, these are some common signs that it’s time to resurface:

  • Mineral stains
  • Cracks and leaks
  • Water level reduction
  • Chalky residue
  • Coarse texture
  • Flaking plaster
  • Gunite exposure

Redoing the Interior Finish

  • Plaster: This is the most popular type of pool finish and also the least expensive. The surface is smooth. However, because of its porosity, it doesn’t last as long as other finishes. Plaster needs to be resurfaced every 3 to 7 years.
  • Aggregate: This finish offers your pool a unique style. This finish is also known as a pebble pool and it contains ceramic-coated stone or pre-mixed sand in a plaster product. 

Visually, this finish creates the appearance of pebbles on your pool’s surface. There is a wide range of colour options and over time, these colours become richer and deeper. Aggregate finishes last for up to 25 years.

  • Tile: Endless options in colour, style, and design make this a versatile finish. They do not require much maintenance and are quite durable with proper maintenance. The tile lasts for 5 to 10 years.
  • Fibreglass: Fiberglass pools require fewer chemicals to maintain pH balance because of their nonporous materials. It is also more durable than plaster and more resistant to stains and cracks. Fibreglass pools last for 15-30 years.

Alternatives to Resurfacing Your Pool

  • Patching – If you notice any worn out plaster or areas that need patching up, this can be done as a temporary measure before you’re ready for a whole resurfacing project
  • Acid Wash – Acid washing is a quick fix for stains, but beware that it is not suitable for use on plaster, which will wash away
  • Tile – Instead of aggregate, plaster, or fibreglass, consider tiling your pool. It will last longer and is easy to maintain
  • Paint – If there isn’t any extensive damage to your pool’s surface, repainting is a cheaper alternative to resurfacing

After taking your pool’s surface and signs of wear and tear into consideration, keep an eye on how often you need to clean your pool. If it appears clean and intact, you may not need resurfacing after 10 years.
