| Subject: | Veneer Plaster (1/2/2007) |
| Question: | Are contractors using a base coat (scratch coat)on the seams and corners before applying the finish coat of plaster, or are they leaving it rough for the finish coat? |
|
| Answer: | A few plasterers try different applications on their seams because of cracking issues they are experiencing. It is a false assumption that the basecoat will perform any better than the DIAMOND or IMPERIAL plasters when joint or corner cracking occurs. Cracking is most often related to movement within the structure, but jobsite conditions that the "plasterer" and builder should be controlling could be adding to the problem, i.e. heat, water, bag goods and surface temperatures, relative humidity, air flow, etc. |
