Product Information

Full details

The PBSL Group External Corner Trim is designed for professional installers and DIY enthusiasts looking to secure and finish external right-angle joints on composite cladding projects. Its primary benefit is the seamless integration of cladding boards with added edge protection, though users should note that the 3.6m length requires careful handling and transport to avoid bending or surface marring during installation.

FAQs

Can I use this trim for internal corners?

No, this profile is specifically designed for external 90-degree right angles. Using it for internal corners will result in an improper fit.

What tools do I need to cut the trim?

A standard hacksaw or a power mitre saw with a fine-tooth blade will produce clean, accurate cuts.

Does the grey finish fade over time?

The trim is designed for exterior use and features a weather-resistant finish; however, some minimal fading may occur over many years depending on sun exposure.

Is the trim flexible?

The trim is rigid to maintain a straight, professional line. Do not attempt to bend it around curved surfaces.

Can I paint the trim a different color?

While the factory grey finish is durable, you can paint it with a high-quality exterior-grade plastic or metal paint if required, provided you prime the surface first.

Troubleshooting

Trim does not sit flush against the corner

Check that your composite panels were installed perfectly square and that no debris is stuck behind the trim.

Trim appears to be moving or vibrating

Ensure that enough adhesive was applied during the initial installation or add additional color-matched fasteners.

Pros and Cons

Pros

  • Provides a clean, professional visual finish
  • Protects exposed panel edges from moisture ingress
  • Durable construction suitable for outdoor environments
  • Easy to cut to exact size using standard wood-working tools

Cons

  • 3.6m length can be difficult to transport in smaller vehicles
  • Requires precise measurement to ensure perfect corner alignment
  • Limited to 90-degree external angle applications only

Setup, Compatibility & Care

Installation Steps

  1. Measure the vertical height of your corner and mark the trim accordingly.
  2. Use a fine-tooth saw to cut the trim to the desired length.
  3. Apply a thin, consistent bead of exterior-grade construction adhesive to the internal faces of the trim.
  4. Press firmly against the corner, ensuring it is level and flush with both adjacent cladding panels.
  5. Secure with color-coded screws if additional structural reinforcement is required.

Care Instructions

To maintain the aesthetic appeal, clean the trim periodically using a soft brush and mild soapy water. Avoid using abrasive pads or harsh chemical solvents, as these may degrade the protective grey finish over time.
