We have used Bio-Shield® for over 40 years in a demanding commercial environment on a wide range of surfaces, from cleaning concrete to Coloursteel, roofs to driveways. Bio-Shield works, we have build our reputation on it. Bio-Shield will give a powerful, rapid kill of moss, fungal, algal and lichen growths, and can prevent re-growths. It can be used to clean any exterior surface.
For the correct application of these exterior cleaners, it is important the surface being treated is saturated and kept wet until the moss, mould and lichens are dead - in as little as 15 to 20 minutes using Bio-Shield®.
Porous surfaces such as concrete or timber will soak up the applied solution; so the 105 litres of diluted solution made with a 5 litre bottle of Bio-Shield® Concentrate provides more than sufficient coverage for a successful result in most domestic situations.
When Bio-Shield® is used on non porous or smooth surfaces such as painted weather boards or a Coloursteel roof, coverage will be greatly increased, making Bio-Shield® even more cost effective.
