thanks for that, another question do you wack the blocks after you finish the cutting in before the sand and then again with the sand or do you just do it with the sand?

Once the paving is complete brush sand over the area leaving on a thin layer then drive the wacker over it all twice, then brush off making sure all the joints are full.
Unless your using clays or blocks that have a textured face, as sand on the surface can scuff up the blocks leaving marks. If that’s the case then brush in sand, clear the surface, wack then top up joints. Hope that makes sense.
