Description
Technical Field

There are many types of concrete coating equipment on the market. For example: a concrete leveling coating device disclosed in Chinese patent CN215051851U, a concrete surface coating tool disclosed in Chinese patent CN216587813U, a concrete vibrator with coating function disclosed in Chinese patent CN219952731U, etc. are all relatively common concrete coating equipment.
