Block Blitz Block Paving Eco Cleaner. Removes and Prevents Algae, Moss, and Black Spot. Deters Weed Growth for up to 6 Months. 8x Pouches. Treats 120 sq/m.

Excellent product. So easy to supply. Well worth buying a watering can with the product at the same time as ordering the Block Blitz. I use the product in September and again in March to keep the block paving free of weeds and moss. Never have the block paving jet washed. Because this washes away the sand foundation. Applying Block Blitz by the method indicated prevents any damage occurring.

I've been using Block Blitz for a number of years now on our granite block paving. It's brilliant. Very easy to use. Literally, mix, leave for a while, (I usually mix a second lot to let them stand) Stir again and it's good to go. I have 2 watering cans, which I use just for this so I don't get any contamination when watering plants. It literally takes half an hour to do the lot and it usually takes 10 sachets. The only thing I can say is PLEASE WEAR GLOVES. I took mine off once to do something else, and forgot to put them back on and my hands were quite sore afterwards. This is not a complaint, it was my own fault. (I always wear wellies too!) Highly recommend this product.

Apply when dry and watch. Within a week, the moss turns brown and the brick and paving cleans up a dream. Heavier soiled parts need 2nd treatment a few weeks later. Highly recommend.

First saw this on a shopping channel, then checked the manufacturers website info. Have used for 2 years now, very happy with this Eco friendly product. No more back braking raking between paving blocks or filthy jet washing sessions. The product takes a few minutes to dissolve - give it a good stir - then water over the block paving and leave to work its magic. The coverage estimates on the packs is accurate I have found. Over the following few weeks it slowly cleans the paving and inhibits weed and moss growth between the blocks. An easy twice a year way to keep block paving looking smart and clean. Highly recommend.

This stuff is the best I have used to clear our driveway. We'll worth the money 👍

It’s so easy to apply, one sachet in one watering can and away you go. Sit back and let it get to work. It doesn’t happen overnight and to be honest for 2 or 3 days it looked a bit messy as it dried white. After the first rain it looked amazing. I used it the same time last year and it’s only just needed re doing . A super product

Such an easy way to clean driveways although one sachet doen't go very far.

One application since last winter. My paving stones were ugly from moss. Physical cleaning couldn’t do better than what this stuff has achieved now it’s autumn again! Really good but why so expensive???
