> Have you noticed whether this affects its hardness or strength?> --- > Ted Larson According to the technical experts at the US Gypsum Co., the correct way to measure and mix plaster, including Hydrocal, is by weight. This assures the proper chemical reactions take place fully. For complete mixing, add the powder to the water and not the other way around. Most Hydrocal used by model railroaders is considered "fast dry" and sets up in 5-10 minutes or less. However, there is another version of Hydocal named "FGR95" which takes about 45-60 minutes to set up with the same strength as the fast dry stuff we have become familiar with. FGR95 is also a product of US Gypsum Co. US Gypsum Co has an 800 number for customer support and the fellow there was very helpful with all my questions. Personally, I like the slower setting stuff since rushing is not my style and getting everything "just right" before it hardens is important to my way of thinking. Good luck...Ed L.
