THE PROJECT
Constructed in 1903, this working lighthouse received significant concrete repairs and a full repaint. Close-up views of the heritage facade are part of the visitor experience, for those who climb the 59 steps to the lighthouse balcony. A highly protective coating solution was required to keep the upper facade looking good for years to come. Accommodating movement and weather protection were key requirements.
THE SOLUTION
A range of Fosroc and other Dulux Construction Solutions products were used in the concrete repair and repaint executed by Marine & Civil Maintenance.
Step 1: All damaged concrete was broken out.
Step 2: All exposed steel reinforcement was primed with Fosroc Nitoprime Zinrich to actively resist corrosion.
Step 3: Fosroc Renderoc LA55 was used for deep section patch repairs while Fosroc Renderoc HB40 was used for vertical and overhead repairs.
Step 4: The Fosroc Nitofill LV injection system was used to repair cracked concrete that did not require breaking out.
Step 5: The balcony walkway received a Nitoprime and Nitoproof waterproofing system that delivered Class P5 slip resistance.
Step 6: Emer-Clad Facade was used to waterproof and protect the facade surrounding the lighthouse beacon.
Step 7: Dulux Protective Coatings Durebild STE and Weathermax HBR were used to repaint the entire lighthouse.
