KingPin Bowling – Townsville Project Summary
Rust Conversion | Thermal Insulation | Asset Life Extension
Project Overview
Luther College, a private secondary school in Melbourne’s eastern suburb of Croydon, was facing widespread deterioration of its aging roof infrastructure. Having opened in 1964, many of the original galvanised steel roofs had developed extensive surface rust and advanced corrosion by the mid-2010s — particularly from 2009 onwards.
By 2014, roof sheet corrosion had reached a critical point, with full replacement looming as the only apparent solution. Instead, Thermoshield was commissioned to implement a comprehensive restoration and protection system that extended the roof’s life while delivering a refreshed visual and thermal upgrade.
Key Benefits Delivered
Advanced Rust Conversion & Surface Stabilisation
- All roof sheets underwent deep surface preparation including power washing and full rust conversion treatment.
- Severely affected areas were treated with high-performance primers and sealing products to halt corrosion.
- Prevented further degradation without the need for full roof replacement.
Visual Restoration & Modern Finish
- Thermoshield was applied in a multi-layer system:
- 1st Coat: Thermoshield White (insulating and reflective base layer)
- 2nd & 3rd Coats: Thermoshield Shale Grey (UV-stable and aesthetic topcoats)
- Resulted in a visually transformed roof surface with a “like new” appearance.
Thermal Insulation & Energy Efficiency
- The ceramic membrane dramatically reduced solar heat absorption.
- Helped regulate internal classroom temperatures and decreased cooling loads.
- Created a more comfortable learning environment for students and staff.
Asset Life Extension & Cost Avoidance
- Avoided full roof replacement by restoring structural integrity.
- Delayed future capital expenditure by 10+ years with a high-performance coating system.
- Provided ongoing waterproofing and UV protection in a single solution.
Scope of Works
- High-pressure surface cleaning
- Rust converter application to affected sheets and fixings
- Base coat application of Thermoshield White
- Two finishing coats of Thermoshield Shale Grey
- Quality checks and finish validation for full system performance
Before | During | After
- Before: Widespread rust bloom, patchy finish, visual deterioration
- During: Cleaned and sealed surface, visible rust converter and base coat
- After: Smooth, uniform grey membrane — aesthetically and functionally renewed
Client Outcome
“We were at the point of budgeting for full roof replacement. The Thermoshield system gave us a completely restored, insulated, and protected roof — without the cost or disruption of replacement.”
This project highlights how Thermoshield provided Luther College with a practical and cost-effective alternative to full roof replacement, ensuring long-term protection, thermal performance, and visual enhancement.
