In addition to repairs inside the room, the angle with the grid is widely used in the installation of insulation systems for facades of buildings. One of the design requirements for insulation of external walls of buildings is to cover the seams of insulation or polystyrene slabs with fiberglass. The grid angle performs this function on the corners and slopes of buildings.
On a corner of a design put putty, then establish a corner with a grid so that through openings in a corner the solution has left. Using a spatula, the grid along the entire length is lowered into the solution on both sides of the corner. Then the solution on the surface of the corner is leveled with a spatula flush with the wall. As a result, we obtain the reinforcement of adjacent surfaces, formed an ideally equal angle.
