Nexus ProJoint RapidFlow Preparation

Ensure the surface of the paving is clean prior to application. Check the joints are cleaned out to a depth of 20mm ensuring 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 Nexus ProJoint RapidFlow cures when it dries out so water/rain must have a route of escape.

Nexus ProJoint RapidFlow Application

Apply Nexus ProJoint RapidFlow 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. Nexus ProJoint RapidFlow is ideal for porcelain and natural stone paving.
