At Stoneworld we strongly advise you to lay our Natural Stone Paving products on a full bed of wet mortar made using a cement and sand mix created using Mixed Soft Sand. (Ratio 5 sand :1 cement) It creates the ideal medium for you to work with when laying and levelling the stone slabs into place. Not too wet or too dry!
Take our advice: Using other types of sand will not create the great end result you are looking to achieve. Builders sand will create a mix that is too sloppy, whilst sharp sand makes a mix that holds too much air , and will therefore not create enough suction in the mix for the slabs to ‘stick’ to. Our mix is 50% soft and 50% sharp-just right for the job.
