Fibreglass

UNIQUE BENEFITS FOR FIBREGLASS SUBSTRATE ROOFS
Tight Bonding
One of the unique benefits of applying a polyurethane coating to a fibreglass (GRP) roof is its ability to form a tight bond with the fibreglass substrate. Unlike other roofing substrates, fibreglass has a smooth and non-porous surface that can be difficult to coat with traditional coatings, causing problems including, poor adhesion, peeling, and other issues that can compromise the performance and longevity of the coating.
Polyurethane coatings are formulated to bond tightly with fibreglass and many other substrates/surfaces. The liquid coating penetrates the surface of the fibreglass, filling in any cracks or gaps and creating a strong and durable bond that resists peeling, cracking, and other forms of damage
Chemically Bonded
Polyurethane coatings have the ability to chemically bond with the fibreglass surface, creating a strong and durable barrier that is highly resistant to water, chemicals, and UV radiation.
Additional Benefits

UV Resistance – Fibreglass roofs are vulnerable to damage from the sun’s UV rays, which can cause the material to degrade over time. Polyurethane coatings are resistant to UV radiation and can help protect fibreglass from UV damage, extending the lifespan of the roof.

Enhanced Aesthetics – Polyurethane coatings can be customised with various colours and finishes to improve the overall appearance of a fibreglass roof. This can be particularly useful in commercial or industrial settings where aesthetics are important.

Improved Energy Efficiency – The coating can improve the energy efficiency of the building by reducing heat transfer and minimizing air leakage, resulting in lower energy bills and a more comfortable indoor environment.

Reduced Maintenance and Repair Costs – By extending the lifespan of the fibreglass roof and reducing the likelihood of damage and degradation, the use of a polyurethane coating reduces the need for maintenance and repairs, resulting in lower costs over the long term.

Application – Full Reinforcement
Application is achieved by full reinforcement with chop strand glass fibre matting due to the number of visible and invisible non-linear cracks, delamination, weathering, and water damage the are all common issues with this type of roof.
Final Word
The unique benefits of applying a polyurethane coating to a fibreglass roof are its ability to bond tightly with the substrate, creating a durable and long-lasting barrier that is highly resistant to environmental damage, and providing a flexible and customisable aesthetic appearance, but it also provides a single seamless and jointless finish that eliminates the risk of roof joint failure, all with easy application.
