Jointing cobblestones.

Bicky

I have about 80+ square meters of cobblestones in my back yard which are a real pain to keep weed free. They were laid badly and had sand put between the joints which is useless for keeping the weeds out.
I power washed the whole thing with the intention of putting jointing compound down but when i went to my local builders supplier i was shocked by the price.
Forty euro for a 20kg bucket would cost my first born child to do the whole area. Someone suggested a mix of sand to cement but said it sould badly stain the cobbles and would not be water permeable.
Does anyone have any suggestions?
What mix of sand to cement would i use?
Thanks,
jp

Salt is cheap - not many weeds can live in salty sand. Buy 1kg bags & brush into the joints.

5 litres of White vinegar cost about €3-50, mixed with salt & washing up liquid (helps it stick to conc. ) makes a cheap weedkiller.

Thanks.
I had seen this suggestion already so I mIght go for a mix of sand, salt and cemet. Probably will do a test patch at the back end of the yard to see how it turns out first.
I might spring for a few buckets of Geofix for the area directly at the back door.

Well don't do what i did
Cement stains destroying the cobblestones now. If i could do it again i would save a bit of money and buy the geofix.
