Its easy to apply with a fine rose watering can but the results are slow to show. Over weeks however improvements were noticed in the reduction of grass and weed and an improvement in colour. Much cheaper than having the drive cleaned and sealed. I was able co er an area of about70 to 80 sq meters with the two packs.

Visible results may take time, so patience is key. However, in my experience, consistent application, such as twice a year in spring and autumn, effectively prevents algae growth and significantly reduces weeds.If your patio heavy algae and weeds, I recommend power washing it thoroughly before applying this product. Regular treatment will help prevent the need for power washing in the future.I would recommend it to anyone seeking a long-term solution for controlling algae and weeds on their patio. Personally I use it with little water ratio.

Have lots of green covered paving slabs. Tried this once and it cleared them all completely. I was very dubious that it would work by just using a watering can and leaving it but by golly it did.

This spray and leave is absolutely brilliant it's very strong it says on the label you should notice it working with in a week but I noticed it working the next day it removes the green and black algae and very good value for the money and it covers very well goes along way thank you.
