A gorgeous shot of a lap pool with the words, "Understanding Pool Plaster."

Your swimming pool is your escape, an oasis. You step into the water, and your stresses and cares float away. And, thanks to the pool’s plaster, your oasis is protected and leakproof. It’s important to understand how to care for and replace it.

How Is Pool Plaster Applied?

Pool plaster should only be applied by trained pool professionals, such as your local experts at Liquidus Pool Services. Improperly applied plaster can lead to premature cracking, weakened sections that can threaten the integrity of your pool, and costly repair expenses.

When you contact our team for a pool plastering service, here is what you can expect.

Draining the Pool

One of the most dangerous steps of a replastering service is draining the pool, but it’s important for two reasons. Firstly, it helps our team get a better idea of the condition of the current plaster. Secondly, it allows us to repair the plaster correctly without damaging the infrastructure of your pool.

Removing the Old Plaster

Removing the plaster allows us to start with a clean slate.

Applying New Tile, Coping, and Plaster

New tile and coping are applied to help transform the visual aesthetic of your pool, giving it a gorgeous transformation. Next, we replaster, and finally refill your pool with water, making sure to balance it before we call the job complete. The chemical makeup of your pool’s water is extremely important for the health of your pool’s plaster and can greatly affect its lifespan.

The Relationship Between Water and Pool Plaster

Our team at Liquidus Pool Services offers comprehensive routine maintenance services for your pool. Our extensive knowledge and experience allows us to detect warning signs of defective plaster.

Pool Water PH

The pH level of your pool is a strong indicator of the health of your pool’s plaster. Water with a pH below 7.0 is too acidic for your pool and can eat away at the plaster. The pool’s smooth surface can become coarse and rough, which can be damaging to swimsuits and uncomfortable on feet.

On the opposite end of the spectrum, pH levels over 8 cause the plaster to develop stains and scaling. Not only do stains look unsightly, but they can also cause your pool’s water chemistry to be thrown off balance faster.

Liquidus Insight:

It’s important to also keep an eye on your pool water calcium level. Too much calcium can result in unsightly deposits to develop on your pool’s plaster, and too little calcium can lead to brittle plaster.

Pesky Stains

The most common issue pool owners face is stains. However, what most pool owners don’t know is that there are different types of stains that can affect their pool.

Organic Stains

Organic stains are the result of plants living near your pool. Debris and dead leaves can fall into your pool and over time can turn your plaster brown or green, depending on the type of plant. For example, a leaf’s chlorophyll will leave a green stain on your plaster while a twig will leave a brown hue due to its natural acids.

These stains are usually naturally dissolved due to the chlorine in your water as it will naturally bleach the plaster.

Mottling

Pool plaster mottling is a term used to describe when the plaster begins to take on variations of color. Mottling is typically associated with darker plasters but they can often show up on the lighter shades as well. Controlling your pool’s water chemistry can help prevent mottling.

Dissolved Metals

Iron and copper saturating the surface of your pool’s water can result in metal stains. These stains are characterized by their dark streaks that include patches of blue-green hues. Though some stains can, especially from iron, can be black or brown.

Can I Clean My Pool’s Plaster?

Yes! Pool plaster can be cleaned through the following techniques:

  • Skim the Surface
    • Helps remove debris before it has the chance to stain your pool.
  • Brush the Plaster
    • Brushing the walls of the pool can also help remove debris, making it easier for you or the filter to remove it from the pool.
  • Balance Your Water Chemistry
    • One of the most important things you can do to protect your pool is to balance the water chemistry.
  • Invest in an Acid Wash Service
    • The acid wash helps remove a thin layer of plaster which helps remove the surface stains.
