How Long Should Mastic Last Around A Pool?

What is mastic sealant?

Also known as pool mastic, mastic sealant is a flexible, waterproof material used to fill joints and gaps in pool decks, coping stones, and expansion joints.

However, like many other materials exposed to the elements, mastic sealant deteriorates over time, so regular maintenance checks are essential to identify any trouble areas and ensure they are quickly fixed.

Why is proper mastic sealing important?

Water leaking into the foundations of your pool can cause significant, costly damage, including cracks in the pool shell and erosion of the pool’s foundation. Mastic sealing around the pool prevents water leakage and creates a watertight seal to protect the surrounding stones or decking.

Mastic sealant also helps maintain the high-quality look of your pool area by preventing weed growth, insect infestations, and the accumulation of dirt in the gaps.

What is the expected lifespan of mastic sealant?

The lifespan of mastic sealant can vary depending on several factors, including:

  • the quality of the sealant: high-quality sealants will withstand harsh weather conditions and UV exposure meaning they generally last longer than lower-quality alternatives.
  • weather conditions: if your pool is located in an area with extreme weather conditions, such as the intense Texan heat, the mastic sealant may deteriorate more quickly, so it’s important to choose a sealant suitable for the climate.
  • the frequency of pool usage: pools that are used year-round or extensively during the swimming season may experience more wear and tear on the mastic sealant as there is regular foot traffic and exposure to pool chemicals.

What are the signs of deterioration?

To know when it’s time to replace your pool’s mastic sealant, keep an eye out for these signs of deterioration:

  • Cracking
  • Discoloration
  • Brittle / loss of flexibility
  • Weed growth or dirt in the gaps
