ProJoint™ Fusion™ is a very quick and easy paving joint filler designed for areas of pedestrian paving. For vehicle trafficked areas use one of our 2-part epoxy systems such as ProJoint™ MAX™ or V75-WT™.



Ensure the surface of the paving is clean prior to application. Check the joints are cleaned out to a depth of 25mm observing a minimum joint width of 3mm, and that the paving is firmly bedded and stable prior to filling joints. Paving should be laid on a permeable bedding mix as Fusion™ cures when it dries out so water/rain must have a route of escape.



Apply Fusion™ when surface temperature is above 0°C. Liberally soak the paving first and then empty the mix evenly onto the surface and work quickly into the joints using a brush or squeegee. Mist the surface and compound with a soft spray of water to flush the material down into the joints. Top up any low joints and repeat as necessary. Once the water has drained away then sweep the paving with a fresh soft brush at 45° to the joints, and remove any excess. A trowel or iron can be used to achieve a traditional finish if required.

The product can be used in light rain but prolonged and heavy rain will delay the curing process and increase the risk of fluid damage. ProJoint™ Fusion™ is not recommended for porcelain – please refer to ProJoint™ Porcelain™ products. ProJoint™ Fusion™ may highlight and enhance the natural surface colours and textures of the paving – this can be especially noticeable on grey paving, including granite, so a test area is advised before use. It is important to spread the mix across the total paving area to ensure the potential effect is uniform. Please note that this is a temporary effect and weathering and foot traffic accelerate its disappearance. For extra porous paving or to minimise any effect use V35-UV™.
