Report Abuse. I've actually heard you shouldn't do this because the high pressure completely disturbs the sand bedding the blocks lay on and there shouldn't be any big gaps, the blocks are supposed to fit snug together.Sand is only swept in to the tiny cracks after.o not use cement!!use only cillica sand on block paving.empty out the bag and brush in with a soft brush until gaps are fully filled.then you nedd to re-seal the paving approx 2-3 weeks later.
