There is a lot of misinformation on the Web - some of it even offered by “professionals”. If you are interested in restoration/preservation, look at the U.S. National Parks service for some very accurate information. They have some of the best material available on all aspects of historic preservation. Of particular interest to homeowners with plaster problems are the following:      Preservation Brief 21: Repairing Historic Flat Plaster--Walls and Ceilings Preservation Brief 22: The Preservation and Repair of Historic Stucco Preservation Brief 23: Preserving Historic Ornamental Plaster   You might also find the following information quite useful:      Preservation Brief 10: Exterior Paint Problems on Historic Woodwork Preservation Brief 37: Appropriate Methods for Reducing Lead-Paint Hazards in Historic Housing   For consulting on paint colors, contact:      Susan Robinson-Heaslip http://www.blackthornedesign.com/   Walls & Ceilings Magazine March 2005: Out of the Past Plasterer thrives on natural skill and sage wisdom   September 2008: Young Minds, Old Values A 19th Century ceiling gets Class A restoration using old techniques and modern materials           © Copyright 2008.
