How to apply SCJ Cold Joint Spray

1. Clear any dirt, debris or ponded water from the pothole
2. Use a circular saw with a diamond blade to cut a neat ‘picture frame’ with straight edges around the repair or reinstatement area
3. Use a brush to remove any loose bits of tarmac or debris
4. Seal the vertical edges and base of the hole with SCJ Cold Joint Spray to stop any water ingress
5. Remove the tarmac in its plastic wrapping from the tub and apply gentle pressure to the edge of the bag to soften it
6. Pour the first layer of cold-lay tarmac to a depth of approximately 45mm and compact with a tamp to around 30mm
7. Reapply the cold joint spray to the vertical edges of the hole before adding another layer of cold lay tarmac and compacting again
8. On the final layer, compact well to provide the final surface course
9. Apply Ultracrete Instaband Eco around the edge of the reinstated pothole for added protection and to prevent any water ingress
