Benefits of Polysand

How is Polysand installed(applied)? How does it Dry?
Once your pavers have been laid - Polysand will be spread across the top of the pavers - and swept in using a large, hard bristle broom. The goal is to make sure that sand is swept completely into all existing paver joints - not to exceed the top of the paver ( *1/8 inch below the chamfered edge or the recommended height by the individual manufacturer) . Once in, a compactor will be used to make sure the joints are filled and there are no open gaps. ( If there are, remaining sand will be swept in, and the compactor will be used again ) Once compacting is finished, any excess sand will be removed from the pavers ( via a blower or broom ).
Lastly, using a spray nozzle, shower the paver area. * This is the key step, to activating the binding aspect of the Polysand. Once water is applied, you will blow off any excess water from the pavers - to avoid sand hardening anywhere besides the joint. * Please do not sweep excess Polysand over damp pavers! Once the area is cleaned - allow for the pavers to set - and stay off of the newly installed pavers, for atleast 12-24 hours!
