Deciding between porcelain 18mm and sandstone 24mm both grey. The porcelain cost about 1/3 more however if i have to seal the sandstone the cost isnt that different and over time probably works out more. But i have read conflicting literature saying it doesn't need to be sealed!
Do I need to seal sandstone patio slabs? Short answer, no! Leading paving manufacturers Marshalls and Stonemarket don’t recommend coatings and sealants for their sandstone paving. Knowing this will save you time and money! Quality Indian sandstone does not need sealing, so you won't need to seal even the cheapest Marshalls Indian Sandstone Paving.
