I have a very irregularly shaped area which is block paved. Most of the walls it adjoins are irreguular stonework so the edges are anywhere between 20mm and 1mm from the walls. These gaps are filled with sand in the normal way, but as with all sand in our area it has become home to ants nests and small weeds.

I was thinking that the best way to deal with this is to rake out the sand and then pour hot tar in to the gaps created. Any ideas on wether this is a good good plan or not? I don't have a tar boiler but can possibly hire one, but perhaps there is a pourable setting compound I could use instead?

Tar could become a horrendous mistake if you have an accident. Options i would use would be slurry mortar (cheap and quick) or resin bound pointing compounds like gftk or Romex (expensive and quick).

Yeah I was going to say, forget the tar option!

remove the kiln dried sand and point the gap using a 4:1 mix of sharp sand and cement, don't do the mix too wet otherwise you will get it on the face of the blocks and it will leave a cement stain

buy a couple of different size finger trowels to suit the width your pointing, for example a 20mm and a 10mm
