AN INTRODUCTION TO PLASTERING
Plastering is probably the least mentioned trade under regulations and standard specifications. Material quantities supplied by the Portland cement institute should ensure sound mortar mixes, but to be assured of quality workmanship by trying to enforce building regulations is difficult for plastering.
The architect or designer should be responsible for preparing specifications and details that ensure quality workmanship. A marked sample panel of plaster on site is usually the most effective specification. All plastering on site must conform with the sample panel.
