  • Catnic Expanded Diamond Lath can be fixed to solid backgrounds using masonry nails, plug screws or masonry screws with washers over the lathing. Spacers should be inserted between the lathing and the background to achieve a gap of minimum 8mm to allow render flow through. Lathing sheets should be fixed with length running horizontally and with all strands sloping downwards and away from the finished face of plaster or render. For horizontal work (ceilings) the sheets should be fixed with strands sloping the same direction.
  • Catnic Expanded Diamond Lath fixing to timber supports for horizontal work should be fixed with the length of the sheet running across the timber supports with all the strands sloping in the same direction. Supports should be at centres not exceeding 350mm. Vertical work should be fixed with all strands sloping downwards and away from the finish face. Using nails or staples, start at the centre of a sheet and nail to each successive support working along the mid-line of the sheet towards its edges. The nails or staples should be driven in at an angle pointing away from the sheet centre thereby providing tension to the sheet as they are applied. Fixing should then be completed from the centre to the top and bottom sides starting at the central support and nailing at 100mm centres, maximum. Ends of coil lath should be lapped over supports not less than 100mm and wired together at 150mm centres. Sides should be lapped not less than 100mm and tied with tying wire at approximately 150mm centres.
  • Catnic Expanded Diamond Lath fixing to steel channel should be fixed using 1.22mm soft galvanized steel tying wires at not more than 100mm centres. The tie should be made by forming a hairpin at the end of a length of wire, the length being at least twice the depth of the runner. The hairpin should be pushed bend first up through the lath, close to one side of the runner and pulled back with one leg of the wire on either side of the runner. Both strands of wire should be pulled taut and given a few twists with top cutters before cutting any surplus wire. The twist may then be pushed flat against the lath. Required tension in the sheet may be achieved by passing the leg of the hairpin to one side or the other of the lath junctions in accordance with the direction of the desired tension. Continue installation as for timber supports.
  • Stainless steel rib lath is ideal for refurbishing damaged or aged masonry walls, when a key for rendering is not certain due to disintegration or softening of the wall face. Lath should be fixed with apexes of ribs against the wall, edge ribs of the sheets nesting into each other should be wire-tied every 15cm and ends of sheets should be lapped not less than 2.5cm and nesting ribs securely tied together. Stainless steel fixings should be used at sufficient intervals to hold the lath firmly in position
  • Manufactured from stainless steel to BS EN 10088-2-1.4016 in accordance with BS EN 13658-2: Metal Lath and beads - definitions, requirements and test methods. External rendering.
