Verify that your wall thickness is within the 141-200mm range and ensure that the coping sections are not pushed too far apart.
Touch up small blemishes with a matching exterior-grade black metal paint to maintain the anti-corrosive barrier.
To install, ensure your coping sections are securely fixed to the wall substrate. Align the union over the joint between two coping lengths, ensuring the internal clips or fastening points engage fully with the coping profile. Use appropriate fasteners compatible with aluminium to prevent galvanic corrosion. For maintenance, simply wipe the surface with a non-abrasive cloth and mild soapy water during your seasonal building inspections. Check periodically to ensure the union remains tightly seated and that no sealant has degraded at the seams.
