What sand should i use for my patio?

[djmaniks]

I am making a patio in my garden for general use using Slabs.

It seems to me there are two techniques of laying the slabs...

1. Laying slabs on a dry mix of sharp sand and cement.

2. Laying slabs on a wet Mortar bed.

I would like to use the second technique of a wet mortar bed, and want to know weather to use Sharp sand or Builders sand for this mortar mix?

Does anyone know?
Thanks

Building sand - it stick better so allowing the slab to be tapped down without some of the mortar spots being flattened

Problem with mortar spots is that you can't walk on them until the next day. A full sand bed allows to to walk/work on them straight away

Thanks Woody, I planned on doing a full bed of mortar instead of just 5 spots. In this case would you still suggest Builders Sand?
