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
