Power washing is not normally needed with block paving if it is regularly maintained. But sometimes if your block paving does need cleaning and the dirt and grime is heavy then jet washing your paving does make cleaning of the paved area easier and quicker than having to scrub the paving with a broom.ressure washing block paving should be used to gently clean and rinse the paving rather than used to blast the paving clean.
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.
