Help! I read in the most recent issue of FW that Plaster of Paris can be used to fill grain in open-grained wood such as oak. It is touted there as a perfectly acceptable, fast-drying, and easy-to-use alternative to traditional grain fillers. I was about to begin a project and planned to follow the advice in the article. However, I happened to mention this idea to a few people (each of tham a more experienced woodworker than I) and each of them said that using Plaster of Paris to fill grain is a BAD idea. It is brittle, they said, and will not flex as wood contracts and expands with temperature and moisture changes. They predicted it would "pop" and recommended a product such as Durham's Water Putty. I am confused. (I am working on a project and will be investing quite a lot of time; I don't want to have my finished piece begin to show cracks in the grain.....) Can anyone advise me? If you have actually used Plaster of Paris in this way, how has it worked out? Any problems? Cautions?
