Algae and mould: a chronic problem on the shaded court
8 min read Updated: 12 October 2026
Regular Maintenance – Regular Cleaning
What should you do if algae forms?
Leaves, dust and organic debris on the court must be removed.
Any standing water should be removed using a suitable water-scooper; the court should not be used until it is completely dry.
What should be done to prevent it from forming again?
Leaves and dirt should be cleared away regularly, with particular attention paid to shaded corners.
Puddles of water after rain should be cleared away, and drainage channels kept clear.
Areas where water constantly pools should be repaired by a specialist team.
Garden irrigation systems must be prevented from wetting the court.
Stiff wire brushes, abrasive cleaning and high-pressure water applied too close to the surface can damage the acrylic coating. Regular cleaning and the prevention of water pooling are essential maintenance steps that reduce the risk of algae growth.
