First we pressure wash the entire surface with an industrial-grade pressure washer that will remove all weeds, dirt and vast majority of the stains. If you have oil stains we will use a special solution to remove them, in addition to the pressure washing.
After the weeds and dirt are washed out you will have empty gaps between your stones. This gaps will be filled with highest-quality polymeric sand. Polymeric sand hardens, keeping the weeds from growing out again and keeping the stones from shifting and going in waves.
Last step! Sealer is applied to the surface, bringing out the stone’s natural colour and adding some shine. How much shine? Depends on your personal preference, we have different levels of shine to choose from.
