Catnic Plasterer's Beads

Corrosion Protection

In normal circumstances, matured plaster work may be regarded as dry and therefore non-corrosive. Risks of corrosion in galvanised beads only normally become apparent during the initial plaster drying out period, which should be kept to a minimum, and subsequently during periods of heavy condensation. The use of sand or water contaminated with soluble salts in plastering mixes should be avoided as should soluble chlorides as they are likely to increase the risk of metal corrosion. The presence of sea salts in sand used in plastering which is in contact with galvanized beads will often cause rust staining and should therefore be avoided.

In external applications and, in conditions where heavy condensation, persistent damp or regular exposure to moisture are likely, stainless steel, PVCu or PVCu nosed beads should be specified.

In general, care should be taken to ensure that metal beads are kept dry and distortion is prevented during storage and handling. Care should also be taken to prevent mechanical damage to the galvanized coating. Stainless steel beads are for use specifically with cement based renders. Contact our Technical Services Department if considering the use of stainless steel beads with gypsum plaster, as stainless steel should not be used in conjunction with this product.
