Detailed Application

E280 - Trim Application

Application Instructions

E280 is used both to create expansion joints on large roofs (over 50m2), create rolls on any ridge details and can be used to bridge GRP to felt roofs. It is compatible with C5 closures. An adequate gap in the deck should be cut if necessary, the trim should then be nailed to each end of the decking at 300mm centres. The join over the nails should then be bandaged and the laminate can be applied over the trim. To bond these trims together, or to cap with C5 closures, apply a thin strip of Diamond Trim adhesive to the inside edge of the overlapping trim and rub into place.

The E280 can also be used to bridge between a GRP and adjoining felt roof. The E280 should be fixed to the decking at the end of the GRP roof taking up the felt at the edge if possible to lay the trim underneath. The felt should either be bonded to the trim with a liberal coating of Topflex acrylic roof coating both under and over the felt layer. Alternatively, a torch-on strip can be used over the joint as the edge trim profiles are flame resistant. This should be completed before the laminate is laid over the other edge of the trim.

Ballustrade Support Fixing/Balconies

Application Instructions

Balustrade support fixings can be installed onto a completed GRP laminate after it has cured. The timber plinth is laminated to the substrate and then topcoated. The balustrade is then screwed into the plinth and the holes and area around the screws are completely sealed with polyurethane (PU) adhesive. Always ensure the roof area on which the fixing will be laminated is clean, dry and free from debris, wiping the surface down with acetone will help to remove any contaminants present in the laminate. It may help to clean and abrade the surface with medium grade sand paper before wiping with acetone to increase the inter-laminar adhesion.

When applying GRP to balconies or any other area which will be subject to heavy foot traffic, a 600g/m2 laminate should always be used.

It is also advisable to incorporate a non-slip aggregate finish into the topcoat. Always take extra care to ensure a good quality finish when installing GRP on a walkway or balcony.
