What the heck is Polymeric Sand? Good question and one we get all the time. Polymeric is a fancy science name that basically means, for our purposes anyways, a manufactured sand that has been created to serve a certain purpose.
What is that purpose? To bind with water so that the sand seals between the pavers. This serves several advantage such as:
Great Joint stabilization
Discourages weed growth and ant infestation
Added resistance against natural erosion (normal sand may wear away overtime)
Quick & simple application
It comes in multiple colours which gives a more aesthetic appearance of paver joint .
What do you need? (Besides the polymeric sand, of course)
How do you use it? (You are full of great questions today!)
Make sure you have ran a small compactor over your paver project. This help keep them from shifting later on.
Grab a bag, I recommend buying some at Island Cache Stone Company (of course), and pour it around your fantastic paver project. Did you use the Flagstone Pavers? They are one of my favourite and a perfect example for polymeric sand. Note: Make sure the pavers are dry before doing this or the sand will start to activate.
Simply sweep the sand between the cracks with an every day push broom, making sure that the cracks are filled, but don't overfill or leave any on top of the pavers themselves. A good rule of thumb us to leave a 1/8" gap.
Grab your trusty compactor and give a few passes over the pavers in all directions. Note: You may need to repeat steps 3 & 4 at least once more as the sand settles.
"Just add water!" Grab your favourite hose and spray onto the pavers, while allowing the water to settle and absorb into the cracks. You don't need blast it on and blow the sand out. The activation process has begun. Note: Try your best to ensure you leave the pavers as clean as possible, as it may be hard to clean after it dries.
This may be the most important step...Enjoy your new pavers!
