FAQs

Can I use this trim on 45-degree corners?

No, this specific component is designed exclusively for 90-degree internal corners.

Is the black color permanent?

Yes, the material is UV-stabilized to resist fading and discoloration over time.

Do I need special glue to install this?

Generally, stainless steel pins are sufficient, but a small amount of low-modulus silicone can be used for extra stability.

How do I cut the plastic without cracking it?

Use a fine-toothed hacksaw or a power saw with a PVC-rated blade, and cut slowly to avoid heat buildup.

Is this trim paintable?

It is not recommended to paint the trim, as the factory finish is designed to be low-maintenance and weather-resistant.

Can this be used for external corners?

No, this is an internal corner trim. You would need an external corner component for external angles.

Troubleshooting

Trim does not sit flush against the fascia

Check if the corner angle is exactly 90 degrees; if the wall structure is uneven, slight sanding of the back of the trim may be necessary.

Trim is too long for the fascia board

Use a fine-toothed hacksaw to trim the excess length from the bottom of the corner piece.

Pros and Cons

Pros

  • Resistant to UV rays and environmental weathering
  • Easy to cut to exact size requirements
  • Provides a clean, professional finish to roofline joints
  • Compatible with a wide range of standard fascia profiles

Cons

  • Requires manual trimming for non-standard fascia depths
  • Fixed 300mm length may require multiple units for deeper fascia runs
  • Specific to 90-degree corners; not suitable for obtuse or acute angles

Setup, Compatibility & Care

To install, ensure the internal corner is free of debris. Measure your fascia height and trim the corner piece accordingly using a hacksaw. Secure the trim using stainless steel plastic-headed pins, ensuring you do not overtighten, which can cause cracking. This product is compatible with most standard PVC fascia systems. To maintain, simply wipe down with a soft cloth and mild soapy water once or twice a year to remove dust and maintain the black finish.
