Wet & Forget or Rapid Application will treat any biological growth, that is, moss, mould, algae and lichen. The unsightly green or black growth that is often found around the pool is easy to treat. Spray the dry surface area to the point of saturation with either Wet & Forget or Rapid Application but make sure there is no rain for 6 hours and allow the weathering to do the rest!!
For Lichen growth, saturate the area with diluted Wet & Forget only (as the dilution for Rapid Application is different), wait 15 minutes. Then saturate the area a second time. This allows Wet & Forget to break down the top layer and penetrate right through to the roots of the lichen.
Green moss and algae growth will take a couple of weeks to fully decompose.
Black mould will take much longer to fully decompose as the contamination is obviously worse than normal green moss.
Wet & Forget or Rapid Application are suitable for all types of pool surrounds that are covered in mould, moss, algae or lichen such as concrete, ceramic tiles, stone tiles, sandstone, pavers, timber, brick and painted surface areas.
Because Wet & Forget or Rapid Application are nearly pH neutral, any overspray will not change your pool's pH. Don't forget the poolside furniture that may be covered in black mould or slimy green algae!! Suitable to apply on all types of outdoor furniture, plastic, timber, stone/concrete, aluminium and wrought iron. If your outdoor cushions, plastic pool lounges and pool noodles have gone mouldy then use either Wet & Forget or Rapid Application. Make sure you thoroughly rinse all the residual off, prior to using them in or out of the pool.
