Painting Fence Best product to kill Algae?

bettz · 5 Apr 2020 at 15:27

Thought it was time to paint the fence as im getting through jobs quite quick whilst im in lockdown

Got some Cuprinol Ducksback in Silver Copse as our fence doesnt get any sun in the summer its got a lot of algae on it what product would be best?

I've seen bleach mentioned (not the most wildlife friendly option)

Also been looking at this stuff from screwfix

You could try this https://www.force4.co.uk/item/Force...utm_medium=base&utm_campaign=base&stock=56273

Gets good reviews on Amazon but is quite pricey

I used watered down bleach and an old paintbrush and painted it onto the fence, then left it a few days. Worked a treat, though I'm not sure it's particularly eco friendly as you say, though I doubt any algae killing chemicals are.

The cheapest way is surely to give it a scrub using some elbow grease? Stiff brush and some detergent? Pretty sure that's what I've done in the past.

Someone mentioned a pressure washer when I searched.

Patio Magic sprayed then left for a few days. That would work.

Any biocide product I guess.

Bleach is perfectly fine to use

it breaks down in 24-48hours, its used in the aquarium hobby to clean fish tanks

I did try that but thought there must be an easier way lol

Looks good!

Despite having a south facing garden, our rear fence on the inside bit is always in a shade, so we have lots of moss/algae growing on it. Will give this a go before painting it.

"wet and forget" sprayed on then wait about 2 weeks

Sodium hypochlorite (bleach) from a farm supplies place, comes in 25 litre drums, used to be cheap as chips, now like everything has gone up but FAR cheaper than buying little bottles of Domestos. Farmers use it for sanitising dairies.

A big mug full to a normal watering can of water. Apply with a distemper brush, mind your eyes and get it nowhere near fish ponds. It will also bring those paving slabs up like near new put on when damp after rain using a watering can and rose. I do the main path once a year like that to kill algae and moss

Otherwise a steam cleaner although a cold pressure washer of some decent pressure and flow might work. Heat from a proper steam cleaner makes a BIG difference though.

The topic never goes away though...

White vinegar does lots of garden cleaning jobs. Dilute with water 50:50. Reasonably environmentally friendly.

Lawns and fences, never ending...

Tell me about it. New lawns are growing three inches a week at the moment. Nitrate rich layer placed before turf. Fences also need painting before autumn.

At least we removed most of the shrubs requiring regular trims.

Does that work on block paving also?
