If left unprotected and not maintained, wooden garden furniture can soon start to look tired and neglected. Common issues include green or black discolouration as a result of mould, algae and other biological growth. If left untreated for a number of years, the wood will eventually turn grey or silver. The good news is that these issues can usually be resolved.
For mould, algae and other biological growth we recommend using a garden furniture cleaner. Heavily soiled furniture may require 2 treatments.
To help restore the colour of wood that has turned grey or silver, we recommend using Osmo Wood Reviver Gel (6609) or Cuprinol Greyaway Restorer. Wood that has been grey / silver for a number of years may require 2 treatments of the selected wood restorer.
To protect cleaned and restored garden furniture prior to oiling, we recommend using an exterior wood preservative, suitable for garden furniture.
To re-nourish, protect and restore the appearance of wooden garden furniture, we recommend using a garden furniture oil.
The advice on how to protect wooden garden furniture can depend on if the furniture is new or old, untreated or pre-treated, and what type of wood it is made from.
Generally speaking, most wooden garden furniture is either tanalised or oiled. New and old softwood and hardwood garden furniture is usually maintained by periodically applying a garden furniture oil. If the furniture has not been treated for a number of years, has green or black staining, or has turned grey or silver, it will need several treatments to restore its appearance. See the question on 'how to clean garden furniture' for a step by step guide and the products we recommend.
Teak garden furniture is highly resistant to weathering and usually just needs cleaning with a garden furniture cleaner and a fresh treatment of Teak Oil to restore the appearance of tired looking wood.
Teak garden furniture that has turned grey or silver should be treated with a wood restorer such as Cuprinol Greyaway Restorer or Osmo Wood Reviver Gel prior to applying garden furniture oil. This will help to restore the original colour of the wood prior to oiling.
If the furniture is new, untreated or tanalised wood then the answer is likely to be yes. We recommend using a dedicated garden paint such as Cuprinol Garden Shades or Ronseal Garden Paint and doing a small test area, on the underside of the table or chair first to test colour and product suitability.
Old garden furniture that has been left untreated for a number of years and where the wood has turned grey or silver over time can usually be lightly sanded then painted. Water-based garden paints can be problematic on new garden furniture made from dense, exotic hardwoods such as Teak, or furniture that has an oiled finish.
Older garden furniture that has been affected by mould, algae and other biological matter must be thoroughly cleaned prior to painting with a mould and mildew cleaner.
