Positioning: Firstly, use the ruler to determine the installation position, ensure that the longitudinal position of each position is on a straight line, the installation distance and design requirements shall prevail, and the installation site shall be flat, dry, clean and seamless. 2. Mixing glue: using dedicated A glue and B glue, A glue and B glue ratio is 1:1 (such as: 1 kg A glue, 1 kg B glue) glue must be evenly mixed, consistent color. 3. Applying glue: the road surface should be cleaned during installation, the glue should be moderate, not only stick to the ground, but also do not overflow too much, about 40 grams of glue per lihgt, apply glue to the bottom of the road sign.
