A method and system for the rapid formation of a joint at adjacent sheets/panels of plasterboard and cellulose-cement board (e.g. for walls and ceilings) is disclosed. The method and system provides for a two-coat methodology and system, whereby a second coat application of base coat can be eliminated, with the attendant advantages of speed, reduced cost and reduced complexity. The base coat is able to provide underlying joint strength whilst having low shrinkage and good adhesion to the tape. The topping compound also has a comparable degree of low shrinkage, as well as good spread-ability, high sand-ability and a smooth surface finish once applied and sanded. 7110778 1 (GHMailers- P99139 A[ J 1 SAMANTHA |
