Nice video. We do all the same methods except the tamping. I think its a wasteful step for a re sand and seal.

Same here. Same method add poly sand and seal but if the pabers/bricks are washed out (undermined) by too much water and pressure a vibrating tamper helps get the sand under.
I just try to minimize washout with a lower pressure and smaller gpm rate.

It's fun to do pavers!

I find wet sanding a real pita. We wait for pavers to dry, sweep in sand real good, sweep off excess and seal. Have not had any problem with it. We also offer a warrantee.

Same here Steve.
Let dry. Sweep in sand. Lightly blow and sweep excess off and wet to activate the bonding agent then seal.
Not all paver sand is the same so read up on instructions.
