Wood Acid is a ready-to-use liquid product designed for the treatment of external wood surfaces such as decking and cladding. It can be used to remove dirt, atmospheric staining & mould as well as lightening and colour equalisation.

After treatment, surfaces can remain raw or covered with a stain or another type of protective coating. If you are planning to treat stained or varnished wood, the surfaces must first be stripped before using Wood Acid.
