Step-by-Step Installation Guide

This section outlines a comprehensive step-by-step installation guide for Skyline's aluminium coping systems. These instructions apply to both level and sloped coping systems, ensuring a successful and durable installation.

Tools and Materials Needed

Having the right tools and materials on hand before you start is essential. Here's what you'll need:

  • High-Quality Screws: Suitable for the substrate and environmental conditions.

  • EPDM Seals: For effective waterproofing and cushioning between the coping and the brackets.

  • Measuring Tape, Level, and Pencil: For accurate placement and alignment.

  • Drill and Appropriate Drill Bits: For making pilot holes and securing the brackets.

  • Safety Equipment: Gloves, goggles, and possibly a hard hat depending on the installation environment.

  • Step 1: Substrate Preparation

  • Materials Required: Marine ply (minimum 18mm thick), weatherproof membrane (supplied by others).

  • Action: Ensure the substrate is level and solid. Install marine ply followed by a weatherproof membrane to prepare the surface for coping installation.

Bracket Installation

  • Step 2: Positioning and Installing Brackets

  • Materials Required: Fixing straps supplied, screws (No.12 x 50mm round head) supplied by others.

  • Action: Position each bracket centrally over the wall, maintaining a minimum gap of 10mm from the bracket's inside return edge to the external wall surface. Use the screws to secure the brackets at recommended distances (1.5m maximum centres), ensuring each bracket is level and firmly attached.

Coping Installation

  • Step 3: Installing the Coping

  • Action: Start by positioning the coping at one end, aligning it with the wall's edge. Clip the coping under the front angle of the bracket and press down to compress the EPDM seal, ensuring a tight and secure fit. Repeat this process along the wall, ensuring each piece of coping is securely fastened and aligned with the next.

Securing and Finishing

  • Step 4: Securing the Coping

  • Materials Required: Additional screws if necessary.

  • Action: For deeper edged coping or where additional security is required, use a small self-tapper on the coping return to fully secure the coping in place.

  • Step 5: Final Adjustments and Expansion Gaps

  • Action: Ensure a 3-4mm expansion gap is maintained at all joints to allow for thermal expansion. This prevents any buckling or misalignment due to temperature changes.

Cutting and Custom Fitting

  • Step 6: Custom Fitting

  • Tools Required: Metalwork tools (e.g., circular saw), touch-up paint.

  • Action: Measure and cut the coping to fit any unique dimensions between corners, piers, and stop ends. Apply touch-up paint to cut edges to prevent corrosion and provide a finished look.

Important Notes

  • Always double-check the alignment and security of each section before moving to the next.

  • Consult Skyline’s technical support team for any specific challenges or configurations that are not standard.

Maintenance and Care

Maintaining your newly installed Skyline aluminium coping is crucial for ensuring its longevity and retaining its aesthetic appeal. Here are some maintenance tips to keep your aluminium coping in top condition:

  • Regular Cleaning: Periodically remove debris such as leaves, dirt, and other materials that may accumulate on the coping. This can be done using a soft brush or cloth to avoid scratching the surface.

  • Check for Damage: Inspect the coping for any signs of wear, damage, or loosening fixings, especially after extreme weather conditions. Early detection can prevent more extensive repairs later.

  • Avoid Harsh Chemicals: When cleaning, avoid using harsh chemicals that can corrode the aluminium or damage the protective coating. Use mild soapy water instead for cleaning.
