As a leading flat roofing company in Essex, Mikra Services is often asked about the best practices for applying top coats on fibreglass roofs. In this article, we will discuss the importance of top coats on fibreglass roofs, the recommended number of coats, and the benefits of using a high-quality top coat.

A fibreglass roof, also known as a GRP (Glass Reinforced Polyester) roof, is a type of flat roof that is made from a combination of fibreglass and resin. It is a popular choice for flat roofs in Essex due to its durability, water resistance, and low maintenance requirements.

A top coat is a protective layer that is applied to the surface of a fibreglass roof to provide additional protection against the elements. It helps to prevent water ingress, UV damage, and wear and tear on the roof. A top coat can also enhance the appearance of the roof and make it easier to clean.

The number of top coats required on a fibreglass roof depends on several factors, including the age and condition of the roof, the level of exposure to the elements, and the desired level of protection. As a general rule, we recommend applying two to three top coats on a fibreglass roof.
The first coat is typically a primer coat that is applied to the surface of the roof to create a strong bond between the roof and the top coat. The second coat is the main top coat that provides the majority of the protection. A third coat can be applied for added protection and to enhance the appearance of the roof.

There are several types of top coats available for fibreglass roofs, including water-based and solvent-based coatings. We recommend using a high-quality, water-based top coat that is specifically designed for use on fibreglass roofs. These coatings are easy to apply, dry quickly, and provide excellent protection against the elements.

The amount of top coat required will depend on the size of the roof and the number of coats being applied. As a general rule, we recommend applying 1-2 kg of top coat per square metre of roof surface. This will provide a sufficient amount of protection without wasting material.

The best temperature to apply a top coat on a fibreglass roof is between 10°C and 25°C. This temperature range allows the top coat to dry quickly and evenly, ensuring a strong bond between the roof and the top coat.

While it is possible to apply a top coat on a fibreglass roof yourself, we recommend hiring a professional roofing company like Mikra Services to do the job. Our team of experienced roofers has the training and expertise to apply a top coat quickly and efficiently, ensuring a high-quality finish and long-lasting protection.
