   Builders A Quarterly Publication from Boral PlasterboardSummer Edition 2001 Boral  for   Avoiding  Maintenance Streets ahead on  about this edition 2 Maintenance W ith a growing competitiveness in the buildingindustry and an increase in consumerexpectations and awareness on what isacceptable and what is not, the need topresent a high quality finish with both paintand plaster has never been greater. Many difficulties are experienced in trying to satisfycustomer demands with their sometimes unrealisticperceptions of what can economically be providedwith plasterboard jointed surfaces. Combine this withthe belief that an automotive finish can be achievedon a shoestring budget and a somewhat suspectreluctance to concede that restrictions areencountered by the role glancing light plays in thehighlighting of surface variations. Only then can youbegin to understand how disputes arise.Plasterboard in its present form is the most popularinterior lining material used in today’s domesticconstruction and provides the finish over many andvaried substrates, relying heavily on most othertrades conforming to correct building practice inorder to achieve the expected flat surface.Unfortunately all too often quality suffers as a resultof price. It goes without saying “there is no suchthing as a good cheap job”. In the majority of cases,you get only what you pay for, nothing more.One again in this issue we have taken theopportunity to highlightindustry issues. Ourprimary intent is toprevent future problemsby highlighting existingpractices some of whichhave unseen drawbacks;and then providepreferred alternativeprocedures. We illustratewhat has happened in thepast and will happenagain if the approvedguidelines are notfollowed. It is not ourintention to allocate blameor responsibilities, ourgoal is maintenanceprevention and if we allwork together everybodywins. We thank you foryour interest.
