What are the methods for line marking in parking lot and garage ? In order to regulate road safety, various roads and   garages are filled with different types of markings. There are two main construction methods for line marking, namely cold spray marking and hot melt marking. Combining the effects of the two, hot melt marking is the most widely used method.

1. Cold spray marking

Cold spray marking is also called normal temperature marking, which refers to the method of drawing lines directly by diluting the marking paint and then using a cold spray marking machine without heating the paint. The color is clear and the process is relatively simple.

2. Hot melt marking

Hot melt marking refers to the melting of the marking paint in the paint bucket by heating it. It is generally composed of thermoplastic resin, pigments and fillers, reflective materials and other additives. The hot-melt coating is powdery at room temperature. It will dry. In order to prevent the hot-melt paint from peeling, the paint primer is usually applied. Some pavements will also be sprinkled with reflective glass beads to increase the reflective recognition at night; for hot-melt road coatings, its fluidity It is a very important technical indicator in the construction process. It adjusts the proportion of glint in the coating. Under the premise of ensuring the quality, the coating has good fluidity and the proportion of coating resin cannot be too small. This ascribing method is much more complicated than cold spray ascribing.

Compared with the two, hot-melt marking is more popular than cold spray marking because it is wear-resistant, longer-lasting, and safer.
