WOOHOO! Good weather = time to build

I think HD carries the DAP line. The stuff I have been using is called "webpatch 90" or something like that. It is a gypsum based floor leveler and hole filler. I think it is stronger than plaster of paris, and takes longer to set up. I bought it to fill holes in my plaster walls, and it works well for the layout, too. I have mixed it up pretty thin before (about like pancake batter), and it still sets up hard. The thinner you mix it, the longer it takes to set up. But, I suspect if you mix it too thin it will lose strength and be useless.
