Getting Ready

  • Avoid rubbing and damage to Flags by carefully stacking them on timber battens with timber spacers between them.
  • Select paving from different packs throughout the job, to blend colour shades.


  • Make up a slightly wet mortar mix of 1 part cement to 5 parts building sand.
  • Prepare a full bed of mortar ahead of each Flag, approximately 25mm thick, but allowing for the variation in thickness between Flags.
  • Tap the Flag down to the required level, keeping a piece of softwood between hammer and slab.
  • If the Flag will not level with several gentle taps, lift it, adjust the level of the mortar bed and relay the Flag.
  • Draw mortar up to the sides of each Flag before laying adjacent to it. This minimises pointing later on
  • Keep checking levels and gradient across a number of slabs. Stringlines can be helpful to define levels and lines within the laying pattern.

  • Maintain the correct joint width by gently shuffling with a trowel. Small pieces of timber are useful as temporary spacers.
  • If you need to cut Flags, use a power tool with a blade suitable for the type of Flag.

After Laying

  • Do not walk on the paving for at least 24 hours.
  • During wet or frosty weather, cover the paving for protection until mortar has cured.
  • Then point as soon as possible.


  • Where minimal joints are recommended, these should be 2-3mm.
  • Use a damp mortar mix of 1 part cement to 4 parts building sand.
  • Press firmly onto the joints to produce a dense, impervious surface that will drain water across the paving.
  • If mortar gets onto the faces of the Flags, clean off immediately using a damp sponge frequently rinsed in clean water.
  • Bonded sands and other pervious materials are not recommended except where paving is laid with minimal joints. Stonemarket will not accept responsibility for contaminations/staining incurred from use of manufactured jointing compounds.


Our Pavior ranges are specifically designed for high performance in areas used by domestic vehicles. However, many of our customers prefer the look of Flagstones and Millstone Flag, Trustone (Fieldland, Glenmoor and Fellstyle) and Vintage Stone Manor have been used successfully.

Extra care with the foundations is essential. Lay the Flags directly onto a 100mm thick wet concrete bed (1:5 cement:sharp sand) on top of 150mm well compacted hardcore. Damage can be caused by heavy and four wheel drive vehicles, or by using power steering whilst stationery.

    Specific Advice

    Lay Concept paving onto a full mortar bed. Drystone, Pebble and Ammonite slabs have a specially shaped edge that closely interlocks with minimal joints. These joints should be filled by brushing in our Pavior Jointing Sand. Except where they abut the other textures,
    Concept Riven slabs should have 10mm joints pointed with mortar in the normal way.

    Always lay larger face upwards. Coating the back of each Flag with neat wet cement and PVA additive just before laying, will assist bonding.

    These products sometimes absorb colour from Ordinary Portland Cement. We strongly recommend substituting White Cement in the mortar. Lay Arctic Granite with the textured slip resistant face upwards.

    Always coat the back of each unit with 1 part PVA 3 parts water solution.


    This should be dry laid before final positioning on mortar bed.

      Indoor Use

      All of our products can be used indoors as well as outdoors. For indoor use, a coating is preferred to reduce dusting and make cleaning easier.

        Use Around Swimming Pools

        Advice from Stonemarket should be sought about suitability for use of products around swimming pools.

          Coatings / Sealants

          Make sure paving is completely dry and free of efflorescence before applying any coating. Responsibility for the performance of any coating rests with the user and the manufacturer of the coating. Always read the instructions carefully and first test a small area for colour and slip resistance, wet and dry. For further advice refer to Stonemarket sales office.
