Mixing and Application

Once the paving is ready to receive the grout the following method must be adhered to:

    • Immediately prior to jointing it must be ensured that the joints are free from debris and all ponded water removed

    • The paving surface and joints must be pre-soaked and kept wet until the jointing process has been completed

    • A 25kg bag requires 4.25 litres of water and must be mixed for between 3 and 5 minutes until a smooth lump-free consistency has been achieved

    • Apply the mortar without delay. Do not store liquid mortar other than in transit from mixer

    • Mortar must be carefully forced into the joints using a suitable rubber squeegee

    • The mortar should be constantly moved over the surface to repeatedly top up joints in which the mortar may have slumped following initial placement

    • Use the rubber squeegee to remove as much mortar as possible from the surface

    • The surface must be kept constantly moist using a soft spray of water

    • When the jointing mortar has hardened sufficiently or achieved its initial set the paving surface must be cleaned using a brush and copious amounts of water

    • Cleaning must be carried out thoroughly and no mortar must be allowed to remain on the surface of the paving


Technical Details

Flowpoint Smooth is a fully pre-mixed dry-pack which only requires the addition of water on-site. It can fill joints from 3 mm - 50 mm wide with a minimum target depth of 20 mm, up to 200 mm in one application. This highly fluid grout achieves a final compressive strength of 49.6 N/mm2 (results achieved using 4.25 litres of water per 25 kg bag), and will reach initial set in 30 minutes, will accept light foot traffic after 1 hour, and vehicular traffic after 4 hours (dependent upon temperature).



    • Wash all tools frequently

    • Mix only enough material to apply in 4 minutes

    • Never remix or add extra water

    • Wear protective clothing

    • Cool temperatures retard, warm temperatures accelerate

Please note: a small trial should be done to ensure compatibility with the stone being used as it is impossible to test all stone types.



    • Please ensure that appropriate PPE is used when preparing, mixing and applying products

    • Always wash hands before consuming food and make sure that materials are kept safely out of reach of children and animals
    • Avoid skin and eye contact - wet cement can burn the skin
