Bob talks about working with wavy and warped walls with EIFS
The ability to create large, seamless, flat wall surfaces is one of EIFS's unique design features. This attribute is not overlooked by architects and is frequently exploited. However, it is a feature that is not without concerns. A comment that sometimes arises from building owners and architects is that the EIFS does not look as "flat" as they think it should. But what is "flat"?
The subject of flatness is a complex one, and is sometimes a source of great debate. Repairing flatness problems can also take a lot of effort. In serious cases it can mean rebuilding the entire EIFS. It's often a shame to go to such lengths, since the waviness of a wall has no effect on its functionality; it's an aesthetic issue. It's also sad that sometimes a lot of moaning occurs about flatness, even though the problem is only apparent under very rare lighting conditions. This month's column provides some insight into the nature of flatness as it relates to EIFS. Hopefully, you will find this article useful in dealing with this sometimes thorny subject.
