Pool shutter slats: signs of wear

Pool roller shutter apron: wear and tear

The apron is the visible and mobile element of your pool roller shutter. It plays a crucial role in protecting the pool, user safety, and sometimes even in thermal regulation of the water. However, over time, the slats undergo mechanical, chemical, and climatic stresses that eventually alter them. Recognizing signs of wear in time helps prevent a claim and extends the lifespan of the entire system.

1. Cracked, worn, or deformed slats

This is the most obvious sign. A slat that cracks or breaks immediately loses its buoyancy. This imbalances the apron, which rolls up poorly and can strain the motor.

Deformation (warped, twisted, or bowed slats) generally indicates UV overexposure, excessive heat, or poor storage during the off-season.

At Coverdeau, we recommend visually checking the slats at the start of each season, especially in the areas most exposed to the sun.

2. Color change or whitening

Tarnishing, whitening, or the appearance of opaque spots on the slats reflect surface degradation. UV rays, water treatment products (chlorine, bromine, salt), and microorganisms affect the quality of the PVC or polycarbonate.

An apron that changes appearance ages prematurely and becomes more fragile when faced with impacts or hail.

 

3. Poor rolling or friction

When the apron no longer rolls smoothly, if it rubs against the walls, if it jams during travel, or creates jerky movements, it is often linked to:

  • play between the slats,
  • uneven wear among the most heavily used slats,
  • a deformation of the axis linked to an imbalance of the apron.

These anomalies put unnecessary strain on the motor and can cause electrical failure.

4. Water infiltration in the slats

Hollow slats must remain hermetically sealed. When they take on water, they lose their buoyancy, leading to a general imbalance of the apron.

Find right-hand PVC glue-on caps for 71 mm slats and left-hand glue-on caps as well as glue to repair your slats

Infiltration can be due to an impact (hail, falling object), to aging of the caps, or to tired slat welds.

Coverdeau Tip: If a slat remains partially submerged during deployment, it is likely filled with water.

5. Abnormal noises or wear of the fasteners

If the apron bangs in the wind, squeaks, or produces friction at the fasteners, the attachments may be loose or breaking. This small detail can lead to a sudden disconnection of the apron and damage the axis or motor.

It is then necessary to inspect and, if necessary, replace the clips, hooks, or hinges before the situation worsens.

When should replacement be considered?

A well-maintained apron can last 8 to 12 years. But as soon as several slats show defects or the general operation becomes irregular, it is better to consider partial or total replacement, otherwise it may cause a series of failures.

Recognizing the signs of wear on an apron helps prevent motor failures, mechanical imbalances, or risks to users. An annual inspection and a few simple actions are enough to prolong its lifespan.
