Wet paint coating methods

Other wet paint coating methods are summarized in Table 8.6. Application with a brush or roller is now only used to a great extent in the handicrafts sector, do-it-yourself sector, or on building sites. 

The pouring method is commonly used in the wood and timber trade. Here the paint is pumped into a pouring head that has a paint outflow slit with adjustable lips (Fig. 8.5). Paint that does not come into contact with the workpiece is returned to the tank via a collecting channel. Since the paint is constantly circulated and is heated by the circulation pump, it must be cooled and must contain high-boiling solvents. 

Knife coating is used in the paper and textile industry for coating continuous material. Knife coating can also be used to print and coat flat, two-dimensional
