First, apply a layer of plaster on the base layer, then snap a line so that it is clearer. Use a trowel to clean the internal and external corners and surrounding protrusions. If not cleaned properly, the snapped line will encounter obstacles and will not be straight.
2, Snapping Lines for Internal and External Corners. At each vertical internal and external corner, use a plumb bob to establish a vertical line for snapping, and based on the vertical line of the internal and external corner, place a line parallel to it on both sides 500mm respectively, this line is defined as the “Standard Line for Internal and External Corners”.
Before applying putty to the wall surface, use plaster to level both sides of the internal and external corners within 500mm, ensuring that the deviation detected with a 2-meter level is no more than 2mm as the standard. Beyond 500mm from the internal and external corners, smooth with plaster or putty.3, Applying Putty Use putty to straighten the corners along the ink line. Once dry, apply a full layer of plaster, using a 2-meter L-shaped aluminum alloy level with one person pulling each end, push parallel from one side of the internal corner towards the corner, gently move back and forth when reaching the corner, and scrape out parallelly. This treatment of the internal corner will avoid small bends. Once dry, check whether the internal and external corners meet standards, and verify the flatness of the wall surface at the corners based on the vertical line, with deviations within 5mm leveled with wall lining; deviations exceeding 5mm must be leveled with plaster.
