Sandstone Paving, Before you lay the paving stones, the area must be properly prepared. This preparation involves excavation to create the sub-base. The depth of your sub-base depends on the area, but we stock a thickness of 22mm so this should be considered. Next, level the sub-base – the area should ideally slant slightly away from your property to make it easy for water to drain off the slabs. Add mortar on top, then apply priming slurry beneath the slabs before you lay them next to one another. The slurry helps in adhesion and stability. Once all of the pavers are laid, the spaces between them should be sealed. This should be done using top-quality grout. If you aren’t sure which one to use, Ammaari Stones offer a range of colours for the Joint-It Simple compound in addition to our stones. Wait for about 48 hours for the slabs to dry.
