Block paving - in between the gaps
Have a block paving driveway on my property (came with the house).
Seems to be just sand between the blocks, though now it is more sand and weeds. Can I brush out the sand, and use weedkiller then use a dry mix of sand and cement to "seal" the gaps between the blocks ? Also, I have some slabs in the patio - is it recommended to fill the gaps between these with a dry mix of sand and cement ? TIA |

I've heard some say to use a very light cement mix to sprinkle over the top to help seal the sand in but I don't go near the stuff. For patio slabs you should use a sand and cement mix. If you're using it dry then first drench the joints with water then make good as it sets as you would brick pointing. |

Thanks for the advise.
Re the block paving, apart from flooding it with weedkiller, and putting new sand down, any suggestions to keep the weeds at bay? |

It is special kiln dried sand that goes between the joint.

Kiln dried sand will cost a bomb. It might be useful for using as a filler with the sort of resin used with fibre-glass. All you need to do once you have put weed killer down (as you don't own a British made diesel) is brick-sand, a warm, sunny day and a soft broom. |

Where do you shop for your kiln dried sand? Its under £5 a bag and 1 bag does me for a 3 car drive. Steven. |

Use kiln dried sand and brush it in with a broom
Someone on a diy group (this one?) asked a chap spraying weeds using a backpack sprayer, on a pavement area, what brand of weed killer he was using. He replied 'salt and wate"r. Chap who asked the question tried this at home and said it worked. I'll be trying this soon but it may be worth a go. |
