Expanded Metal Lath Sheet
EML
Expanded Metal Lathing is mainly used as a key for internal and external plaster when applied on suspended ceilings and walls. It is also suitable for encasing steel columns and beams, assisting in the protection from fire. In external applications and where there is regular exposure to moisture, heavy condensation, persistent damp or concern that drying out times may be extended, stainless steel should be used.
Available in Galvanised Steel EN 10346 DX51D Z275 or Stainless Steel 1.4016 (Grade 430).
FIXING OF EXPANDED METAL LATHING SHEETS
Fix with the long way of mesh running from support to support, with all strands sloping downwards and inwards from the face of the coating. Always ensure when fixing that allowance is made for overlapping sheets by 50mm lengthways and 25mm widthways.
TIMBER SUPPORT
To connect to timber, use plasterer’s nails & screws with washers or staples at 100mm centres. Start at the centre of the sheet and work out towards the edges. Always fix at an angle to allow lath to be pulled tight. Ensure that compatible corrosion resistant fixings are used; i.e. do not use galvanised fixings with stainless products.
METAL SUPPORT
To fix steel channels, tie with 1.2mm tying wire at 100mm centres. Tie by creating a ‘hairpin’ shape with the wire, then pull tight and twist. Take care that cut wire ends are not close to plaster surface.
TO SOLID BACKGROUND
Expanded Metal Lath can be fixed to a solid background using a suitable fixing with an integral spacer/washer and a large diameter headed screw/nail that will keep the sheets firmly in place.
- Gloves should be worn as edges will be sharp
