We have been asked to fill in a very heavy glacier texture on a clients walls, and make the walls smooth. We have been working at it this past week, and it is coming along nicely. First, Bob went through and taped the ceilings off, knocked off the highest points of the plaster texture, and sanded the roughness down some with sanding screens. We decided to use compound as opposed to hot mud, to not limit our working time with each batch. I like to use a beveled edge trowel and hawk, and Bob likes to use a knife and hawk. We are laying in the first coat completely horizontal, which leaves vertical ridges, and those will be filled in with the second coat going vertically.
