Storage and Protection

The installation of Locusrite beads should be in accordance with BS 5492:1990 (internal) and BS 5492:1991 (external).

The most appropriate Locusrite bead should be chosen to suit the application, required plaster/render depth and desired finish.

Beads should be fixed using plaster dabs or mechanical fixings at a maximum of 600mm intervals. Beads can also be fixed to lath sheets by the use of galvanised or stainless steel tye wire.

Use tinsnips to cut the bead wings and a fine toothed saw to cut the nosing.

Care should be taken to ensure that steel beads are kept dry, and stored and handled in a way to prevent distortion and general damage, especially to the galvanised coating. This means storing them off the ground on a flat surface.

The risk of corrosion in galvanised beads will normally only become apparent during the initial drying out period of the plaster, which should be kept to an absolute minimum (maximum 5-7 days), and subsequently during periods of heavy condensation and dampness.

All metal components used in a particular installation must be of all the same material type, i.e stainless fixings with stainless beads/sheets and galvanised fixings for galvanised bead/sheets.

In external applications and in conditions where heavy condensation, persistent damp or regular exposure to moisture are likely, stainless steel or PVC-U beads must be used.

Stainless steel beads are for use with cement based renders and not for use with gypsum based plasters unless they are specified with an approved protective finish.
