Installation Guide

Installing an aluminum trim corner finish is a straightforward process that both contractors and DIY homeowners can manage with the right tools. The trim not only enhances the appearance of your cladding system but also ensures long-term durability by protecting exposed edges.

Step 1: Measure & Cut
Begin by measuring the exact height or length of the wall where the trim corner will be applied. Use a measuring tape and mark the cutting line carefully. For best results, use a fine-tooth saw or a power saw with a blade designed for cutting aluminum. Always wear protective gloves and goggles when cutting to ensure safety.

Step 2: Position the Trim Corner
Hold the trim corner against the edge of your wall cladding panels to check alignment. The trim should sit flush against the panels without leaving gaps. Take your time during this step — proper positioning will determine how seamless the finished installation looks.

Step 3: Secure the Trim
Once aligned, secure the trim in place using stainless steel screws or the recommended aluminum clips. Screws should be placed evenly along the length of the trim to ensure stability and prevent shifting over time. If using clips, follow the manufacturer’s guidelines for spacing and attachment points.

Step 4: Seal for Weatherproofing
For exterior projects, apply a high-quality exterior sealant along the joints where the trim meets the cladding panels. This will prevent moisture infiltration, protect against corrosion, and extend the life of the installation — especially important in coastal or high-humidity environments.
