Weeds in block paving

[Corb]

Hi , Earlier in the year i jet washed and resanded the joints in my block paved drive but over the last few weeks weeds have returned in the joints .

As i don't really fancy doing this every year would it be possible to spray a non staining weed killer over the drive if so any recommendations would be helpful.

cheers in advance

Sadly this is one of the biggest problem with blocks paving but you can help to prevent it by using the correct weed-killers and the other one is to use acrylic sealer for blocks paving but not cheap and not sure how long it will last. Here one of them.
