Sand to use on top of the limestone base during Travertine Installation

Question: What type of topping sand should I use on top of the limestone base?

Answer: Well compacted regular sand should be used on top of the limestone base.

After the job is completed, sweep Polymeric Sand into the joints. Polymeric sand hardens when it gets wet for the first time and turns into a sort of caulk-like substance, blocking weeds and holding everything in place.
