Polymeric sand, or “poly-sand” seemed great at first. As easy to install as regular sand, almost.

How do you fill gaps between slabs?
- Use a completely dry surface.
- Put together a 4:1 (though some use 3:1) mix of builders sand and cement (do not mix with water!)

How do you fill the gaps on a flagstone patio?
Sand: Sand is the most common joint filler, but it is challenging to keep in place and needs to be refilled. Rocks: You can use small rocks to fill large gaps, and gravel or crushed rock can be used to fill smaller gaps. Mulch: Bark and lightweight chunks of mulch are a great option for in-between flagstone.
What is polymeric sand made of?
Polymeric sand is a manmade compound made by
mixing fine sand with additives, primarily silica
. Landscapers use it in landscaping and construction projects, primarily to fill the joints between pavers. The texture of non-activated polymeric sand is similar to that of regular sand.
