Eco-friendly, mechanically strong & gives extended life.
Scope Of Work
Prepare screens by pressure washing, manual cleaning & scraping, then abrasive blasting to remove marine growth, debris and corrosion deposits. Assess repair work. Apply corrosion protection and Biofoul.
Corroglass 600 Series for repair and re-profiling, with a Polyglass PPA primer coat. Top coat of Biofoul applied for anti-fouling requirements.
• Grit blast whole structure to ISO 8501-1, cleanliness

• Apply Polyglass PPA to whole structure as a primer
for the Corroglass 600 Series, applied to a min.dft
• Apply top coat of Biofoul.
Biofoul is an eco-friendly non-toxic coating. The
mechanism by which Biofoul provides anti-fouling
properties enables the product to be used in both static
and self-polishing environments.
The coating is mechanically strong (unlike many
Self-polishing anti-foulants), has a long life (when used
in conjunction with a Corrocoat corrosion system) and
By applying a final coat of Biofoul, the Power Station
has eliminated the costly requirement for regular
cleaning & maintenance by divers.
In addition to this replacing these screens would have
cost considerably more than re-profiling and protecting
