Katepal Bitumen Triangular Batten is a triangular strip designed for smoothing corners in various structures. It is made of SBS-bitumen, protected by a thin meltable plastic film. It should be heat-welded to the substrate using a propane burner, which ensures a strong bond. After heating, the batten can be shaped to the surface using a trowel. Katepal Bitumen Triangular Batten can be used for different upstands, effectively replacing wooden triangular battens or concrete bevels.
