Lay a molding
1. To accurately determine the length of molding required, measure each of the four sides of the part, their dimensions may not be identical. Then cut the necessary molding into several pieces: their installation will be simpler. Connect them to the wall with miter cuts (ie 45°). Make these cuts with a miter box and a saw, also known as a "sterling" saw or framer's saw. This saw is shorter than the hand saw. It has a rectangular blade, reinforced in its upper part by a metal rib which increases its rigidity. Its very fine teeth ensure precise cuts.
2. Using a liquid glue, specially designed for expanded polystyrene foam, carefully glue the molding along its entire length. Spread the glue with a flat brush, also called "cod tail".
3. Apply the glue on the entire part of the wall that will receive the molding and on the edge of the polystyrene slabs touching this wall, always with the small flat brush. When wall and molding are glued, fix it by pressing strongly on it. Connect in the corners by placing a second molding edge to edge with the first already laid.
Glue a rosette to the ceiling
1. Prepare the rosette that will adorn the middle of the ceiling. If the room is equipped with a ceiling, do not forget to drill the center of this rosette, to allow the passage of the electric cables. Do it with a square tip. This tool, usually used for pre-drilling, is more than enough for polystyrene, a very soft material.
2. Glue the back of the escutcheon and the part of the ceiling where it will be placed. For decorative reasons, avoid placing the rosette on the ceiling already covered with polystyrene slabs.
3. Determine the exact location of the middle of the ceiling by drawing the perpendicular axes. Then put in place the glued rosette. Proceed in the same way as when fixing the molding.
