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.
