Causes of plaque deterioration
The metal and all physical and design features of Phoenix bronze plaques will remain intact indefinitely. The paint or patina and surface protective coating will breakdown over time and detract from the overall appearance of the plaque. Consequently our care and maintenance recommendations are directed to preserving these elements.
- Paint colour and integrity can be effected by ultraviolet light, temperature and other weather extremes.
- Patina can be affected by weather, industrial fall out and other atmospheric polution.
The clear protective coating can be affected in a variety of ways including:
- Industrial fall out may chemically attack the paint film
- Over a period of time, accumulated dirt and airborne pollutants will combine with normal weathering and may dull or bleach the coating
- Natural substances such as bird droppings, insect stains and tree saps may mark or etch the film.
- Water containing salt or other minerals such as bore water may cause the coating to fade
Care and Maintenance Recommendations
As a general rule it is best to leave the plaque surface untouched. Only commence these procedures if and when obvious deterioration or staining occurs.
Plaques with Painted Background and Clear Protective Coating:
- Clean the plaque with warm water and detergent.
- If necessary use a brush with soft plastic bristles such as a toothbrush.
- Do not use a wire brush or abrasive cleaning products.
- Rinse with clear water.
Plaques with Patina or Bare Metal Finish
- Clean plaque as above.
- If the surface is tarnished or oxidised leaving an unattractive appearance, carefully rub over the surface with a fine “Scotch Brite” pad’
- Wipe off the surface until it is clean and dry.
- Apply a thin even coating of Microcrystalline wax.
- Allow to dry and polish with a soft cloth.
Refurbishment
If surface deterioration is such that the above measures are not effective, refurbishment is an option and this is covered on a separate information sheet.
