Everbuild 404 Fast Powerful Fungicidal Wash – Removes Lichens, Fungi and Algae – Exterior and Interior use – 5 Litre

I found this wash to be extremely powerful in keeping off mould and various disease off my patio. It works pretty quickly whilst just pouring on the effective area. I also put this wash on certain spots where otherwise spraying them via a spray bottle to remove smaller green mouldy areas. I felt it took around 1520 minutes to activate when it activated it left an extremely clean patio. I’ve bought this twice now and will continue to buy throughout the year when and if my patio needs cleaning overall I’d say good value for money and I’d recommend.

Good value for the price 👌

Sprayed this product on my mother's transparent conservatory sun roof, left it for 20 mins, then scrubbed with a telescopic brush which removed all signs of algae. I'd tried to remove the algae without using the chemical but couldn't.

This didn't work for me even on unpainted wood it worked for like 2 days.

Bought to clean moss growth off my wall. Seems to of done the job, took a couple of applications, but the instructions were clear and easy to follow.Seems value for money and worked as i had hoped.

I bought this to clean up a patio in York stone that had been down for over 15 years, and was very black in places the slabs looked tired. Sprayed it on, then scrubbed with a hard bristle brush, takes a bit of effect, let is soak and power washed it off. Very happy, brought the York stone up as if was newly layed. It had a low odour, foam up when power washed. Have cleaned the patio about a year ago now and is still looking good. Yes would be buying again

Bought to remove green algae from the pale render at the back of our house (north facing). Applied easily using a garden pressure sprayer and then power washed off after leaving a while. Has worked a treat and render looks as new. This was applied on new style k Rend silicone render and had no issues. Will probably reapply on a regular basis to try and prevent reoccurrence next time rather than leave until it’s gone green.

used this to get rid of the green algae on my fence prior to painting..WOW this stuff works...algae gone by the next day !...btw i didnt rinse it off....
