Protection & Care
Indian sandstone is naturally porous — especially once it is sawn. An impregnating sealer keeps water, oil and organic staining out of the pore structure without changing how the stone looks.
A sealer is not a coating. It sinks into the stone and lines the pores, so liquid beads and lifts instead of soaking in.
Our impregnating sealer is made for Indian sandstone, limestone and Kota stone. It sinks into the pores instead of forming a coating on top, so the surface keeps its natural look.
For sawn paving, seal before laying, on all six sides. To check that it is still working, splash some water on the stone: if the water beads, the sealer is doing its job; if the stone darkens, it is time for a top-up coat.
Sawn and honed sandstone benefits most, because cutting opens the pores. Riven sandstone, limestone and Kota stone all benefit in high-traffic or food-preparation areas. Basalt and granite are far denser and often need no sealer at all.
Before, on all six sides, for sawn paving. This is the single most effective step against efflorescence and picture framing. A top-up coat after laying and grouting finishes the job.
It depends on traffic, exposure and the sealer used. A simple field test: splash water on the surface. If it beads, the sealer is working. If it darkens the stone, it is time to re-coat.
An impregnating sealer is designed not to. Some products are sold specifically as colour-enhancing and will deepen the tone. Always test on an offcut before committing to a full patio.
We can include sealer and grout in the same container as your paving order.
