The invention relates to equipment and a method for coating treatment on the surface of mesh fabric. The method is characterized by comprising steps as follows: (1) the uncoated mesh fabric is cut to be in the size smaller than the plan view size of an inner bin cavity; (2) the cut uncoated mesh fabric is nested to a bulge part in a vacuum bin; (3) the vacuum bin is covered with a matched cover; (4) a valve at a coating flow-in port is closed, air exhaust is performed at a coating flow-out port, the vacuum bin is pumped into a vacuum state, the valve is opened, the coating enters the inner bin cavity of the vacuum bin, and the valve is closed when the coating flows out of the coating flow-out port; at the time, inputting of the coating to the coating flow-in port is stopped, air exhaust is continuously performed at the coating flow-out port, and redundant bubbles in the coating are removed; (5) the fabric is taken out after being cured, and the coated mesh fabric is obtained. The equipment is simple to operate, the surface of the mesh fabric in various sizes and shapes can be fully coated with materials having special performance, and the fabric has better functionality.
