Gloom and Bloom
As we descend through Autumn and Winter beckons, almost anyone with an outdoor surface, whether it’s a patio, path, tarmac tennis court, artificial grass tennis court or anartificial grass hockey and football pitch, moss and algae control can be the most important issue to be addressed.
Moss or algae on a patio or path can make it slippery when wet, on a tarmac tennis court it can mean the difference between safety and serious injury. On a synthetic grass tennis court or hockey pitch algae growth can be the prime cause of drainage failure, so controlling it will be of prime importance and should be addresses as soon as it appears.
On tarmac and artificial grass sports surfaces moss is easy to recognize as soon as it shows, I think everybody involved with outdoor surfaces has seen it before, but algae is much more difficult, and is usually only detectable once it impacts the grip or the drainage. At this point it will either (1) make the surface dangerous to play on or (2) the tennis court or pitch starts to hold water.
- if the surface becomes slippery it must be treated immediately with RBT247 at a ratio of 1 part RBT to 10 parts water, and a 5 litre can of neat RBT247 will treat 550sq m of hard surface, if the infestation is particularly bad a second treatment within 7 days is recommended, then further treatments throughout the winter will keep it at bay. The dead algae will still reside in the tarmac and should be washed out with pressure washers and take it away for disposal.
- If it’s causing the artificial grass court or pitch to hold water then it’s far more difficult to treat, simply because of the depth of the surface to be treated. But again it must be treated with RBT247 at a ratio of 1 part RBT to 10 parts water and again 5 Litres will treat 550sq m. However it doesn’t stop there because this must be incorporated into the infill using a reciprocating brush, rotary brush or heavy dragbrush, to mix the chemical thoroughly with the infill / algae. Again as above if particularly heavy infestation is present the surface must be treated again within 7 days to achieve acceptable results.

Photograph here, taken with a USB microscope, show clearly how dense the algae growth in a water based synthetic grass pitch can get, and yet the post treatment photograph, whilst indicating a huge improvement still shows some algae left in the surface which, if left untreated will bloom again and soon the pitch will be back in the Pre Treatment state.
One final point is that while these synthetic grass surfaces can be treated for moss and algae infestation, the truth is that the dead matter will still remain in the carpet, so mid summer deep cleaning must take place at least every year using a machine such as theHorger SKU range. These machines separate the coarse and fine contamination from the sand infill and remove it completely to be disposed of. If the contamination levels are high, i.e. over 10% as determined with a sediment test, then the only safe course of action is to have the surface refurbished, the contamination and contaminated sand removed and new kiln dried material re applied. If the pitch is a water based type i.e. no infill, then it must be cleaned of contamination using the Horger SKR machine.
