What to Fix Before Painting a Pool in the Off-Season

The off-season is one of the smartest times to repaint a swimming pool in Australia. With lower usage and more flexible scheduling, autumn and winter allow you to focus on proper preparation rather than rushing to meet summer deadlines.

But before applying any new coating, it’s essential to fix underlying issues. Painting over unresolved damage may lead to premature failure, no matter how high-quality the product is.

Repair Cracks and Surface Defects First

Small cracks may seem minor, but they can expand over time due to ground movement, temperature changes, or water pressure. If these are not repaired before painting, they can transfer through the new coating and reappear.

Hairline cracks, hollow areas, and surface instability should all be assessed and repaired properly before any paint is applied. A stable substrate ensures better adhesion and long-term durability.

Suitable repair materials and preparation products can be found in the Sealers & Repairs Collection.

Remove Loose or Failing Paint

Painting over unstable or peeling paint is one of the most common mistakes made during off-season projects. Any loose, flaking, or blistered areas must be removed before recoating.

If the existing coating is mostly sound, localised preparation may be sufficient. However, widespread adhesion failure may require more extensive removal.

A clean, solid surface is essential for achieving proper bonding with the new coating.

Address Staining and Surface Contamination

Before painting, remove any contaminants that could interfere with adhesion. Calcium deposits, algae buildup, oils, and chemical residue should all be thoroughly cleaned.

Preparation often includes:

• Pressure cleaning
• Acid etching where appropriate
• Sanding glossy surfaces
• Allowing full drying time

Neglecting this stage may compromise the performance of the new coating.

Tools and preparation equipment to support the process are available in the Accessories Collection.

Check Structural Stability

Paint is a protective coating, not a structural repair solution. If there are signs of structural movement, hollow areas, or delamination within the concrete or pebblecrete, these must be addressed first.

Off-season repainting offers an ideal opportunity to assess the pool shell thoroughly. Fixing structural concerns before coating helps prevent future cracking or lifting.

Confirm Paint Compatibility Before Recoating

Before applying new paint, identify the existing coating system. Switching paint types without removing the old layer can lead to adhesion problems.

Understanding compatibility ensures you select the correct product and avoid premature peeling. Taking the time to confirm this detail is especially important in older pools that may have been repainted multiple times.

FAQs

Do small cracks need to be repaired before painting?

Yes. Even minor cracks should be repaired to prevent them from transferring through the new coating.

Can I paint over slightly peeling areas?

No. Loose or unstable paint must be removed before recoating to ensure proper adhesion.

Is the off-season better for repairs?

Yes. With less urgency to reopen the pool, there is more time to complete preparation correctly.

How dry does the pool need to be before painting?

The surface must be completely dry. Moisture trapped beneath the coating can cause blistering.

Can repainting fix structural problems?

No. Structural issues must be repaired separately before applying paint.
