Flowcoat Brushable

Brushable Polyester Flowcoat for Fibreglass Repairs, Waterproofing & Surface Finishing

Flowcoat Brushable is a pigmented polyester gelcoat designed for creating durable, waterproof surface finishes in fibreglass and composite applications.
Available in 1kg, 4kg and 25kg sizes, and in Jet Black, Seagull Grey and White Gloss colours, this brushable flowcoat is ideal for repairs, maintenance, sealing, and finishing work across marine, automotive, and industrial environments.

Unlike standard gelcoat, Flowcoat Brushable contains a wax additive that allows it to fully cure in air, forming a hard, tack-free surface without the need for additional sealing. This makes it suitable for exposed fibreglass surfaces where a smooth, durable protective coating is required.

Flowcoat Brushable can be easily applied using a brush or roller, allowing controlled coverage across flat or irregular surfaces. It provides excellent adhesion to properly prepared fibreglass laminates while delivering a durable, water-resistant finish.
