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

Brilliant wash! Bought this a few times now to wash down the outside of our cottage. Makes the white walls clean and bright, they look like they have just been painted again! Superb product and very highly recommended.

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.

Applying this, it's like water, except slightly foamy. So it dribbled down the brush handle and on to my hands and wrists when painting above waist height - use gloves etc. I used this on green fence panels and the green disappeared instantly. On coping stones and house walls it didn't have any obvious effect at first - but when I left it on overnight and came back, all the green had vanished. So I'm very pleased with it, and at around a tenner per carton the price seems reasonable.

My bathroom had a leak which caused a hell of a lot of mould. I thought I was going to have to get professionals it at a huge cost but thought I'd give this a go. Wow, it really works. The mould is gone, the smell has gone so now I can put my bathroom right at a fraction of the price. Highly recommend.

Works on algae but doesn't touch lichen at all.

Done the job of getting rid of the moss that was growing outside my front door, I was constantly slipping on the green moss. It’s now goon.

Product cleans very well, arrived on time .

For the price you can’t go wrong does what you want it to do

Questo prodotto (liquido e inodore) mi ha risolto un grosso problema di muffa nera sulle pareti di un appartamento rivolto verso nord. L'imbianchino all'inizio non voleva crederci ma presto ha dovuto ammettere che quel prodotto rappresenta una soluzione efficace, oltre che semplice da applicare sulle parti da trattare (specie dietro al battiscopa). Io posso aggiungere che ho risparmiato molti soldi e l'effetto antimuffa è duraturo. Lo consiglio a chi abbia lo stesso problema.

El envase se agujereo y se derramo por todo el interior de un armario, empapamdo zapatos y baldas... varios meses con el olor insoportable en el dormitorio por no hablar de lo toxico que habrá sido. fatal

Fa sparire letteralmente tutto il muscio sulle beole del giardino, consiglio due trattamenti distanziati di qualche giorno, per una migliore efficacia.

El producto no me limpio absolutamente nada la baranda de piedra de mi terraza...no sé si estaría en mal estado o simplemente es un pésimo producto pero puedo decir que no hizo nada y quizás hasta me quedó más negra

Ho provato diversi di questi prodotti perchè il patio di ingresso è a nord ,e si forma il muschio facilmente ,questo prodotto è uguale a altri prodotti la grande diversità è il prezzo , è un prezzo eccezzionale paragonato ad altri prodotti simili
