Kills Weeds on Paths, Patios & Block Paving

How to kill and prevent weeds on paving, paths & patios.

Why are weeds growing on my block paving or patio?

Regardless of what your builders told you, there is no such thing as a weed free surface.

Forget what you've been told about weed control fabric. It can help but if your paving is built, maintained and cleaned properly it's very rare to see weeds grow, except maybe the notorious Japanese knotweed and some forms of Mares tail.

If you allow muck and dirt to accumulate on your block paving it won't be long before the weeds begin to colonise it. 

In the end weeds grow in or on block paving because of the laziness of householders.

Just like a car, paving requires cleaning and maintenance, do both and you should be able to prevent weeds from growing in the first place. Do only one or none of these things and you're going to have a problem.

If there are gaps in your paving stones or you have allowed dirt to accumulate on the surface, weeds will grow & thrive.

The Easiest Way to Kill Weeds on Paths, Patios and More




We moved into our flat last year and the weeds were out of control. I did the usual thing and scraped them away with a spade but the following year they were back and there seemed to be more! I was sceptical at first but this product did the job and all I did was the spray them, it saved a lot of time, thanks a lot!

I've used hot water and elbow grease as weed killer for years and it does work but the weeds just keep coming back and it doesn't seem to affect the dock, I bought this on recommendation from my neighbour who always seems to have a weed free garden and was shocking to see it work on dock.





I was looking for something that would kill the weeds in a soiled area and let us plant some flowers after. I am happy to say it worked and it didn't kill the bush that the previous tenant obviously chopped down but it is regrowing. Does exactly what it says.

Mr Jeffrey Thomas




Sprayed the weeds before going to Spain for 10 days, when I came back I was pleasantly surprised to see they were all gone, very happy.





Can't fault this, after 5 days you can see it working, all the green weeds are dying and it took less than 10 minutes to do. I followed the instructions and was very happy.

What types of weeds grow there?

Pretty much anything from Daffodils to Daisies, you'll probably notice the same weeds come back, over and over again.

Barring the infamous Japanese Knotweed almost all other kinds of weed can be dealt with easily & quickly.

What to try first:

By far the most popular method of removing weeds from block paving is manually.

On a small area this can be completed in no time and is highly effective, all you need is a hoe or gardening knife.

Simply pull or scrape the weeds using a hoe or similar.

Make sure you get the roots, Perennials like daffodils will regrow from anything you missed!.

When removing weeds with large roots some of the sand or sealant may come away. You should replace this once you've cleaned the surface.

Partially filled or empty joints will be quickly colonised by a new set of weeds. Fill those cracks!

Preventing weeds on block paving:

Once your paving is clear and free from weeds it makes sense to keep it that way.

  • Regular brushing: This disturbs the weeds before they can become established and will prevent any dirt buildup that could help them become established. A brush a day keeps the weeds at bay.
  • Sealants: A good sealant will prevent weeds from settling into the cracks & joints on your block paving. Even the best sealants cannot prevent them if mud, grit and dirt are allowed to accumulate on your paving. Remember to clean!
  • Weed killer: It may not be everyones favourite method but there are numerous safe formulations that are highly effective against block paving weeds. 
  • Cleaning: Regularly cleaning with hot or cold soapy water will prevent the build up of dirt and kill and small weeds. This simple step will save you countless hours of killing weeds each year. Clean your block paving! Avoid acid based cleaners.
