Setup, Compatibility & Care
To install, first ensure your 10mm expansion gap is measured correctly between the two fascia boards.
- Measuring: Measure the vertical height of your fascia board and mark the trim accordingly.
- Cutting: Use a fine-toothed saw or hacksaw to cut the trim to length for a clean edge.
- Applying: Apply a high-quality PVC adhesive to one side of the joint to fix it permanently to one board.
- Sealing: Apply a bead of low-modulus silicone to the other side. This is crucial as it allows the second board to slide against the silicone rather than being glued rigid, which is essential for movement.
For care, simply wipe down the trim with a mild soapy solution during your annual roofline inspection to remove any buildup of debris.
