Before rolling: wash the floating hair with clean water, soak the fluff with water or thinner and spin dry the water, roll off the excess liquid on the waste paper, and then take the paint. When coating, only half of the roller brush is immersed in the material, and then rolled back and forth on the roller tray screed plate to make the material evenly contained.
When rolling: from top to bottom and then from bottom to top, press the "W" shape to roll the paint on the base layer, and then roll evenly; when the roller brush is dry, gently clean the surface that has just been rolled , The width of each roll coating is about 4 times the length of the roller, and one-third of the width of the roller overlaps, so as to avoid the formation of roll marks at the intersection of the coating film. In order to ensure uniform coating and save paint, two rollers should be brushed during rolling. The end force should be uniform. At the beginning of the roller coating, there is more material. The force can be slightly lighter, and then gradually increase. During operation, try not to use your hands and shoulders as much as possible. Only use the roller to flip for coating. The roller rotation speed should not be too fast. , So as not to splash the paint and affect the painting effect, the action should be light when closing the edge, and always proceed from top to bottom. The edge carding technique is the same as brushing. Different sizes of rollers can be used according to the size of different areas.
After the roller brush is finished: stand the roller upright on the table or the ground, put the other hand against the cover on one side, remove the roller sleeve from the bracket, clean the roller, remember to rinse with running water when the roller brush is still wet, and Place it in a ventilated place to dry in case you want to continue using it next time.
