Whats the best way to get moss and algae off garden decking?

Answer 1

A high pressure washer will destroy the surface of wood decking, even brick manufacturers dont recommend you use it on brick surfaces. it damages the skin of bricks and subjects it to moisture deteroriation.

A steam jenny is the best method of removal of that green stuff from your deck. And it will not damage the wood or plants surrounding it I know this works well, Ive not tried bacteria on wood decking, It probably would work well as described below.

However, this ive tried and works very well, if you have a brick or a concrete patio, ordinary bacteria found in compost will nicely rid of that stuff, or you can buy a bag of compost in Lowes which will also rid of it. Simply wet down the patio, throw a few handfulls of the compost onto the greened surface, and brush around wet with an ordinary garage broom. Leave it for a few days, preferably it will rain and wash it away and GONE will be the green from your brick or concrete decking.

Answer 2

hire a reputable powerwashing company, they should have the proper chemicals and know-how to remove the moss and algae without harming the decking

Answer 3

manually,Folks,Manually.lets remember that Algae are really microscopic organisms grown large.
remove with a soft brush.use a biocide if need be.that's fancy speak for soap.
when its really dry,sand a bit.
the real trick is getting them to stay away.
i have my reservations about using lacquer on garden anything. moisture is too high and the film thickness of lacquer is OT impressive.
try Chlorinated paints. originally developed for Boat Hulls & water systems.they withstand moisture very well.absorb heat pretty well.control heat and moisture and you control algae and mould.

I am about to sort they very same problem.There are two things you need to do.Firstly clean it away and then stop it coming back.
Wait till there has been a spell of dry weather and the use a stiff brush.Most of it will come off this way.Then to kill the rest use a weak fungicide/ weedkiller and treat the whole surface.When dry brush off the remainder again.
To stop it coming back I am going to use some decking or fence paint.This has fungicide and algicides incorporated so it should not come back.

Along with stone, mud and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.
