Moss, algae and lichen will grow anywhere there is sunlight and moisture, discoloring and damaging exterior surfaces on commercial and industrial properties, civic facilities, schools, retirement villages and general infrastructure.
These biological growths discolor and destroy protective coatings on building exteriors, and make concrete and asphalt driveways slippery and unsightly.
While waterblast has been the common method for cleaning it wont prevent regrowth, uses large amounts of water and labour and will damage many surfaces being cleaned.
Bio-Shield provides a cost effective, efficient and damage free method for cleaning moss, alga and lichens from any exterior surface.

How to Successfully Apply Bio-Shield®
The key to success of Bio-Shield requires 2 conditions met during the application
1. Apply the Bio-Shield to saturate the growths and the surface being treated
2. Ensure the surface stays wet for 10 to 15 minutes through saturation of the initial coat
Bio-Shield® Case Study - 83% Cost Reduction
A large Regional Council in Northern Queensland previously ran a continuous 12 month program water blast cleaning hard surfaces to keep them clear of slippery black algae.
With a tropical climate and a 5 month wet season, by the time the water blast program was completed the back algae had grown back.
The council contacted us and arranged a trail application of Bio-Shield in place of water blasting.
Within 3 months Bio-Shield was confirmed effective and was selected to replace its water blast cleaning program.
The benefits provided by Bio-Shield included
- 83% reduction in costs of a 2 month Bio-Shield application program by reducing labour, water, fuel, equipment costs.
- The treated surface staying clean for at least a full 12 months.
- No waterblast damage to council assets.
- Minimise disruption from waterblast operations including noise, water overspray and dirt.
- Fully Bio-degradble, quickly breaking down into naturally occurring compounds.
Limitations of Bio-Shield
Bio-Shield will kill moss, algae and lichen on any surface, however to effect a complete clean up the surface must be exposed to rain and weathering. If the treated surface is frequently shaded by overhanging trees or buildings or the treated roof surface is under TV aerials or below downpipes from upper roof levels, the surface may need more frequent applications to keep the surface clear of growth.
The length of time between applications will vary with the substrate and micro-climate around the treated surface.
