A NEW IRON SHEET COATING


The new layer being applied

The whole renovation process is actually getting done. Renewal of iron sheets with a new coating (painting) is one of the works in progress. Coatings are applied in several layers to reduce the chance that pin-holes and thin areas in the coating will coincide in all layers. The aim is to make the isolation of the metal from its environment as complete as possible.

Preservation of iron therefore involves understanding the principles of corrosion. Isolation of iron from the atmosphere involves application of an isolating paint layer, and maintenance of that layer. Breaking of the layer will allow rust topropagate under the paint surface. The action begun with thorough cleaning of dirty and removal of rusty parts on the iron sheets since paint cannot be re-applied to a surface untilall the rust and dirt is thoroughly removed.
