The method includes: (i) preparing a first mixture by mixing a particulate material with a polymeric bonding agent comprising a precursor component and a hardener component; (ii) applying the first mixture to a substrate to form a first uncured surface 4; (iii) identifying an edge 6 of the first uncured surface; (iv) preparing a second mixture by mixing the particulate material with the precursor material of the polymeric binder and either no hardener or insufficient hardener to cure the precursor component of the polymeric bonding agent within a pre-determined time; (v) forming a border region 8 of the second mixture along the edge of the first uncured surface such that a first portion of the second particulate mixture is intermixed with a portion of the first mixture and a second, opposed portion 10 of the second mixture is exposed; (vi) allowing or causing the precursor component of the first mixture to cure or partially cure to provide a first bonded particulate surface; (vii) preparing a third particulate mixture by mixing the particulate material with the polymeric bonding agent comprising the precursor component and the hardener component; and (viii) joining a second bonded particulate surface 12 to the first bonded particulate surface by intermixing a portion of the third particulate mixture with the exposed portion of the second particulate mixture such that the hardener component of the third particulate mixture is able to cure the precursor component of both the second and third particulate mixtures. |
