The information-processing model assumes that the length of time that a memory will be remembered depends on the stage of memory in which it is stored. Other researches have proposed that a memory's duration depends on the depth to which the info is processed or encoded. Levels-of-Processing Model.
Start along an outside corner of the wall if possible. Lay the crown molding upside down on the miter saw table so that the ceiling side of the molding is on the bottom, with the outside of the ceiling side sitting farthest away from the blade; the wall side should be the first edge you cut.. Hold the molding up on the wall so that one side touches the wall and the other touches the ceiling. The wall edge of the mitered end should touch the side of the corner; the ceiling side will protrude slightly past the corner.
Measure the width of the top of your crown molding. If it's one inch wide, plan to remove one inch of popcorn ceiling texture in every location you plan to install crown molding.Scrape the tip of a putty knife across the surface of your ceiling to remove the popcorn texture.Remove only the texture where you plan to install your crown molding unless you plan to retexture the entire surface of your ceiling.ut your crown molding to size so it runs from one corner to the next. Use a miter saw to cut the corners at a 45-degree angle so the corners butt up together. You may use power tools to make all of your cuts, but a miter box and a simple hand saw work just as well.
