This paving can be laid on compacted sand, lean mortar, or fresh concrete. For a harmonious result, we recommend a stone-coloured grout that will highlight the silver and gold tones. For optimal results: Prepare a stable and level surface, Distribute the stones evenly, The joint width must be determined based on the spacing of the stones as observed on the pallet upon delivery. To preserve the shine of your paving, we recommend: the application of a protective water repellent to waterproof the stone, a gentle and regular cleaning supplemented if necessary by our all-surface cleaner.
