    Surface Preparation

    Surfaces to be treated must be dry, free from grease, oil, dirt and previous coatings. Joints should be filled or topped up to the bottom of the chamfer with clean, dry compacted sand of the correct specification.


    Ground temperatures should be between 10°C and 30°C

    Apply only when the blocks, jointing sand and bedding sand are dry and when rain is not expected for at least 24 hours. Only one application is required. Pour directly from the container or apply with a watering can fitted with a rose. Low pressure spray systems can also be used. Do not flush out the jointing sand. Work in areas of approximately 5m2 , distributing the liquid evenly with a foam rubber squeegee. Ensure that the joints are completely filled with liquid and that the joints and pavers have absorbed as much solution as they can. Use the squeegee to remove all unabsorbed liquid from the surface of the pavers.

    Please Note – the product must not be allowed to pond on the surface of the pavers or create a surface film. Any unabsorbed material must be pushed away using the squeegee. Dry conditions at the time of application are important since damp or rain in contact with uncured Watco Block Paving Stabiliser can cause the product to dry with a whitish ‘bloom’. This effect will be exaggerated if any surplus solution is not removed from the blocks with the squeegee at the time of application.


    • Only suitable for application to bare, unsealed standard concrete block pavers, with a joint width not exceeding 3mm - 5mm
    • Not suitable for joints between paving slabs, flagstones, etc. where the joint width could be considerably more
    • Watco Block Paving Stabiliser must not be flushed down drains, storm drains or allowed to enter open water courses
