Internal top coat plaster.
Clay and flax fibre.
Clay finish and self-coloured plasters are a blend of clay and fine aggregate supplied as a dry powder. They have an indefinite shelf life if stored dry and require only mixing with clean water to be ready for use. They harden by drying - no chemical reaction takes place - and so remains workable for a long time and can be re-worked by the addition of water at any time.
Quality of the products is monitored by tests carried out by the manufacturer:
* Tests of physical properties to ensure suitability of clay and aggregates.
* Tests to ensure uniformity and performance of the batched product.
Clay finish and self-coloured plasters are suitable for use on internal surfaces of walls and ceilings. They attach by mechanical bonding to suitable stable and dry substrates, including masonry, clayboard, lime base-coat plasters and plaster-boards.
They are a practical alternative to using gypsum or lime plasters and are compatible with 'breathing' construction in historic and new buildings.
The self-coloured plasters provide a high quality, non-dusting, self-coloured finished surface without the need for further decoration.
