Artificial Turf Moss and Algal Chemical Treatments

Artificial Turf Moss and Algal Chemical Treatments

Moss & Algae

Astro Turf Sports Surfaces such as Artificial Grass Tennis Courts, Synthetic Grass MUGA’s, All Weather Sports Pitches, and other Synthetic Turf Surfaces will continually attract Moss and Algal Spores and allowing them to establish themselves can be detrimental to the Artificial Turf system.  Sand infill and other filled synthetic surfaces provide the ideal seed bed for moss and algae.  The spores are most likely to establish themselves in areas of poor sunlight, poor drainage, poor airflow, areas that are used less, or areas that are surrounded or overhung with vegetation.

Changes in our climate have seen an increase in the effect of moss and algae producing a condition commonly known as Algal Squidge.  Algal squidge flowers during the warm, damp short days of winter to produce a dark green slime (pictured above).  This slime is not only unsightly but extremely hazardous and very slippery.  Algal squidge is most commonly associated with surfaces that drain poorly as it gets its food source from water.  The condition is self promoting as it forms an impenetrable blanket over the surface thus promoting its own growing medium.

To help prevent moss and algal you should:

  • Increase airflow and sunlight to the surface
  • Ensure the surface drains or restore drainage via Rejuvenation
  • Make regular chemical treatments to kill off spores
  • Keep the fill moving to prevent the spores establishing themselves
  • Try to prevent spores infiltrating the enclosure by adjacent sources such as lawns and trees
  • Keep the surface clean and well maintained
