Protecting brick driveway from moss/grass growth

[AMO]

Every couple of years, I have to use Sodium Chlorate to kill off stuff growing in between the bricks on my driveway and then jet wash it followed by laying down kiln sand to fill in the gaps.

I recently had a gardener in who said that there is something I can buy that will allow me to protect the bricks and stop stuff growing in between. He doesn't know what it is called though but said you get it in tubs and it was expensive.

Anyone know what it is called and where to get it from cheaply?

Thanx

He may be thinking of Pathclear, available from most garden centres and sheds. It contains paraquat weedkiller for killing existing weeds, and a long-lasting germination inhibitor (or is it a seedling killer?) to stop germination of fresh seeds. Lasts about four to six months I believe, but certainly not two years. Probably best applied in early spring ie now, and along the gaps between the bricks rather than all over, which would be very wasteful.

I think chlorate is longer lasting.

My approach would be Pathclear, then pressure washing, then a mixture of sand and chlorate in the gaps.. don't want to wash chlorate around the place...it DOES poison for several years.

I would think he's talking about a block sealer, this seals the surface of the blocks and seals/stabilises the sand between them, with the joint sealed nothing grows between them. Buy one that wont affect the colour (unless you want a darker wetlook).

Thanx David and to all else who replied.

What is this block sealer stuff? Where do I find it in B&Q? Is it a sand-like substance or a liquid or what? Whats the best way to apply it?

Thanx

Its a liquid that you apply to the surface with a squeegee, soft brush or spray (if you have sprayer) there are water based ones and spirit/solvent based ones. The water based ones are the non staining ones generally but check on the tin. there should be fine kiln dried sand between your blocks to lock them in position, if it hasn't been applied or has disappeared it will be worth reapplying some before sealing, the sand is brushed over the surface ensuring the joints are filled and then any excess is removed.

I'm not sure if B&Q sell block paving sealer or not, I've not looked for it in there but most builders merchants will sell it.

Thanx again. ;0)

There is a product called GeoFix made by Feb which is designed to point the gaps in paving, described as giving a 'permanent weed resistant finish'.
