Frequently asked questions
Do I need to treat the natural stone once it is laid?
Once laid the paving should be left for a minimum of 24 – 48 hours to allow for the mortar to set. Within 3 – 7 days the mortar should be fully set. A period of 6 weeks should be allowed to let the paving weather in before a good quality suitable sealant can be applied to a clean, dry surface following manufacturers instructions. Sealants protect the stone from accidental staining as well as making it easier to clean. Once sealed cleaning should be achieved using warm soapy water and a stiff brush. Power washers or acid cleaners should not be used as this can cause irreparable damage to the stone and damage mortar joints.

What is the best way to install my patio?
There are many different techniques for laying Indian Sandstone paving, BMG Stones recommend excavating a minimum of 150mm below damp course to allow for correct installation of the paving. If no excavation is required, we recommend edging restraints to ensure correct compaction of the base material. A minimum of 100mm base consisting of compacted type 1 aggregate should then be laid to create a secure and stable foundation for the paving. Consideration should be given to soil conditions when laying the base and increased if necessary for softer soils. Compaction should be completed in layers in depths of approximately 75mm to prevent future settling and subsidence.
A 50mm bed of wet mortar consisting of 6 parts sharp sand and 1 part cement should be used to lay the slabs on. The mixture should not be too wet so that the slab sinks under its own weight, it should be wet enough that it can be shaped and held in a ball, but not so wet that water is expelled as the ball is formed. A plasticiser can also be used to aid workability. Paving should always be laid on a full bed of mortar so that it supports the whole slab, not just the corners. Once laid on the mortar the paving should be bedded in with a rubber mallet to the correct level. String lines and spirit levels will assist achieving consistent levels. When laying paving slabs should be taken from different packs to and mixed to prevent colour banding. A joint width of 10mm is recommended between slabs, this joint should be filled with a suitable grouting compound or a damp mortar consisting of 4 parts building sand to 1 part cement. Compressing with a pointing bar will ensure the joint is fully filled as well as providing a good finish. Excess mortar should be brushed from the surface before it dries to prevent staining.
