I. thoroughly clean and dry the parts that need to be installed with sound-proof sealing strip and the plane position of sealing strip;
Two, choose a good paste position, find the starting point of the paste will be from the beginning of the sealing strip, a little press and paste, pay attention to do not have a little pull the sealing strip action, try to keep the original shape of the sealing strip slowly alignment to find the correct paste path for careful paste; In the position of one knot corner, sealing strip should notice very downy undertake bending to go, do not turn too urgent and affect beautiful.
