The benefits of painting a marcite pool

Painting a marcite pool can offer several benefits, although it should be noted that some sources suggest that plastering may be a more effective long-term solution. Nevertheless, here are some advantages of painting a marcite pool:

Affordability

Painting a pool is generally an affordable option, with paint prices ranging from $100 per gallon, and your pool likely needing up to 10 gallons. Painting can be a good DIY project, saving you money on labor costs.

Ease of Application

Painting a pool is a relatively simple process. After preparing the surface, you can apply the paint with a brush, roller, or spray. Acrylic paints are particularly easy to apply, drying quickly and adhering well to multiple surfaces.

Aesthetic Appeal

Paint can give your pool a fresh, clean, and aesthetically pleasing look. You can choose from a variety of colors and even create custom tones or paint a mural.

Protection

Pool paints are designed to withstand water, chlorine, and sunlight, as well as heavy use. They can protect the underlying surface from damage and extend the life of your pool.

Safety

A new paint job can improve safety for swimmers by reducing slipping issues. Anti-slip solutions can be added to the paint to improve traction and safety.

Overall, painting a marcite pool can be a cost-effective, simple, and aesthetically pleasing way to extend the life of your pool and improve swimmer safety. However, it is important to consider the long-term costs and effectiveness compared to plastering or resurfacing.

The drawbacks of painting a marcite pool

While painting a marcite pool can be an affordable and aesthetically pleasing option, there are several drawbacks to consider.

Firstly, the longevity of a painted pool is significantly shorter than that of a plastered pool. Paint typically lasts between 2 to 7 years, depending on the type of paint and application factors, whereas plaster can last up to 15-20 years when properly maintained. This means that painting a marcite pool may result in more frequent reapplication costs in the long run, making it a less cost-effective solution compared to replastering.

Secondly, the preparation process for painting a marcite pool can be time-consuming and intricate. Proper preparation is critical to ensure the paint adheres well and does not bubble or blister. The pool surface must be cleaned of any contaminants, and previous paint layers may need to be removed or sandblasted, adding to the overall cost and time required.

Additionally, the choice of paint and application technique can impact the durability and safety of the pool. Epoxy paints, for example, require the pool to be completely dry before application, and pool paints in general, can make surfaces slippery, potentially causing safety issues for swimmers.

Furthermore, the appearance of a painted pool may deteriorate over time. Paint may start to wear, peel, and flake after a few years, impacting the aesthetic appeal of the pool. In contrast, plaster, especially pebble plaster or plaster with quartzite flecks, can help hide stains and maintain a more consistent appearance for a longer period.

Lastly, painting a marcite pool may not address underlying issues, such as cracks or structural problems. Simply painting over these issues may provide a temporary solution, but it is essential to address them properly during the resurfacing process to avoid future problems and extend the life of the pool.

The best type of paint to use on a marcite pool

Painting a marcite pool can extend its life, but only if the right paint is used and proper preparation is undertaken.

For bare plaster or marcite pools, epoxies offer the best value. Epoxies are also the best choice for fibreglass pools and steel or aluminium pools, although the latter two require a primer prior to applying the finishing coat. Epoxies are the longest-lasting pool paint type, with a lifespan of up to 8 years, and they are highly resistant to chemicals, stains, and abrasion.

If you are looking for a quick drying time, water-based acrylic pool paint is a good option, although it has the shortest lifespan of the three main paint types (epoxy, premium acrylic, and water-based acrylic), lasting only one season for commercial pools and up to 2 years for residential pools. Acrylic paint should not be used on fibreglass or wood surfaces, or on hot tubs and spas, and it is less chemical-resistant than epoxy paint.

If you are painting a pool that is exposed to direct sunlight, be aware that the colour of the pool paint may prematurely fade in spots due to exposure to concentrated chlorine.

Insl-X Swimming Pool Paints offer four pool paint technologies that can be applied to a variety of substrates, including marcite. These paints can be applied over most types of properly prepared existing pool paints and are suitable for both fresh and saltwater swimming pools.

Before applying any pool paint, it is critical to properly prepare the pool's surface. This includes filling in any cracks, holes, or gouges, and cleaning the surface of any oil, grease, wax, dust, dirt, mildew, suntan oils, or foreign coatings and contaminants. If the pool has been previously painted, it is important to determine what type of paint was used so you can ensure compatibility.

How to prepare a marcite pool for painting

Painting a marcite pool can extend its life by several years, depending on factors such as water chemistry, weather conditions, maintenance routines, and usage patterns. Here is a step-by-step guide on how to prepare a marcite pool for painting:

Step 1: Drain the Pool

First, drain any water from the swimming pool and remove any debris and hydrostatic plugs. This will ensure that the pool surface is ready for cleaning and preparation.

Step 2: Clean and Repair the Surface

Scrub the entire pool surface with a TSP (Tri-Sodium Phosphate) solution to remove any algae, oils, dirt, chalking, peeling paint, or other contaminants. It is recommended to power wash the pool during this process for a thorough cleaning. If there are any cracks, holes, or gouges, fill them with a suitable patching compound or hydraulic cement. Allow the repairs to dry completely before proceeding.

Step 3: Acid Wash (optional)

Acid washing the pool is an optional step but can help ensure better paint adhesion. If you choose to acid wash, pour a diluted acid solution (following manufacturer instructions) into the pool and use a scrub brush to apply it to the walls and floors. Wear proper safety equipment, including goggles, a mask, and gloves, as acid washing can be dangerous. Follow the acid wash with a neutralizing solution, such as bicarbonate of soda or TSP, and then rinse the pool thoroughly with water.

Step 4: Apply Primer (if necessary)

If your pool surface is made of fiberglass or another material that has never been painted before, it is recommended to apply a primer to ensure proper paint adhesion. Use a high-build epoxy primer, mixing the two-part catalyst system in a bucket or the provided can, following the manufacturer's instructions.

Step 5: Allow Drying Time

Before painting, ensure that the pool surface is completely dry. You can test this by attaching clear packing tape to different areas of the pool. If the tape has moisture on the sticky side, the surface needs more time to dry. Allow at least five dry days before painting, or follow the manufacturer's recommendations for drying time.

How long does a painted marcite pool last?

Painting a marcite pool can extend its life, but this depends on several factors. Firstly, the type of paint used is important. For example, Insl-X® Swimming Pool Paint is formulated to protect substrates including marcite, and the company is engaged in efforts to extend the performance and serviceable life of their products. Secondly, the application process is key. Proper preparation is critical, including filling in cracks, holes, and gouges, as well as cleaning the pool surface. Failure to adequately prepare the surface can lead to premature failure.

The longevity of a painted marcite pool is influenced by a variety of factors, including the number of coats applied, climate, strength of chlorination, chemical balance, exposure to direct sun, colour selection, amount of pool usage, and cleaning schedules. Maintaining balanced water chemistry is crucial to extending the lifespan of marcite pools, as chemical imbalances can cause erosion or damage to the marcite. Heavy usage can also lead to more wear and tear, reducing the overall lifespan of the pool.

The typical lifespan of a marcite pool ranges between 8 and 12 years under normal conditions. However, with proper maintenance and installation, a plastered pool can last from 7 to 10 years, and a painted marcite pool can potentially last even longer, especially if you use a quartz aggregate blend for pool plastering, which can add an additional five years to the life of your pool.

To summarise, painting a marcite pool can extend its life, but the longevity of the pool depends on a multitude of factors, including the type of paint and the quality of the application process, as well as ongoing maintenance and usage patterns.

Frequently asked questions

Epoxy paint is the longest-lasting pool paint and is suitable for marcite pools. Epoxy paint can last between 5 and 8 years, whereas acrylic paint will last between 2 and 4 years. You can also use rubber paint, but this has a shorter lifespan than epoxy.

Preparation is critical when painting a pool. First, empty the pool and fill any cracks, holes, or gouges. Then, clean the pool's surface of any oil, grease, wax, dust, dirt, mildew, suntan oils, or foreign coatings and contaminants. If the pool has been previously painted, test to see what type of paint was used. Mix all paint containers together to ensure colour uniformity and consistency.

Painting a marcite pool can extend its life by a few years. However, the paint will eventually start chipping and leave your pool vulnerable to the elements. Properly mixed and maintained pool plaster can last between 15 and 20 years, whereas paint will only last between 2 and 7 years. Pool experts agree that, in the long run, resurfacing your plaster is a better alternative to painting it.
