Manual tamper or do I need a powered plate tamper?

I have a 12x20 patio that I laid thin pavers over top an existing covered slab. The gaps on the brick are tight. About 1/16th". I am using Alliance Super Sand on it. Wondering if I can get by with getting that fine powder down the joints by hand tamping it?

(FYI: the slab had a fine stone aggragate glued on top of it. I first put a skim coat of sand over it before I laid the thin pavers)

Thanks,
Dave

A "powered plate tamper" is very likely going to move your pavers around, especially with the thin layer of sand under them acting like ball bearings. Don't think you want that. Why not work the sand in with some (very) light water-flooding?

No water...

Can't use water, it's polymeric sand. Water activates it when I am done getting it in the cracks.

My bad for not realizing it's polymeric sand. But doing a quick Alliance website review makes me wonder why you packed the pavers in so tightly (1/16"), when the installation instructions suggest joints up to an inch wide to enable proper compaction--plenty wide to manually tamp and compact with the end of a 1 x 4.

If you don't get any helpful suggestions here, maybe a call or email to Alliance's technical support unit would be in order.

I did call them and as I understand it that is up to 1" thick.
I guess I will try on a small section with a 2x4 or 4x4 before I rent a power plate.

Follow-up.
I endedup hand tamping it all... a tough job, but it got the sand down in the cracks as needed and saved me some rental bucks.

Liked the Alliance Super Sand and so did my wallet compared to cost of others.

This project was my first exposure to this forum, surely not my last.
