A very satisfying project to clean, repair and brighten up a large patio, adjoining decking area, and various garden furniture for a cottage near the New Forest. The teak needed a fairly serious amount of scrapping and sanding, before algae treatment, a few light repairs, and final sanding. Underneath the verdigris the teak was actually in very good condition. The terraces, both paving and hardwood, had not been cleaned for some time and both fairly uneven. The 'after' photo here shows only some of the benefit - as the algaecide takes 2-3 weeks to properly clear the 'black spots' engrained in the soft stone slabs.
