Before rolling the paint: clean up the floating hair with clean water, soak the wool with water or thinner, shake off the moisture, roll off the excess liquid on the waste paper and then dip the paint. When dipping, only half of the roller brush is penetrated into the material, and then the roller is turned twice on the homogenizing plate to make its material even.

When rolling paint: from top to bottom and then from bottom to bottom, the paint is rolled on the base according to the "W" shape, and then rolled horizontally: when the roller brush is dry, then the surface of the just rolled paint is lightly trimmed, the total width of each rolling paint is about 4 times the length of the roller, and the roller width is about one-third of the overlap, to prevent the rolling mark at the intersection of the coating film, in order to ensure the symmetry of the coating and save paint, When rolling paint, the roller brush on both sides should be symmetrical, and the rolling paint contains more material at the beginning.

Force can be slightly lighter, then gradually intensified, the operation of the hand and shoulder as far as possible not to force, just rely on the rotation of the drum and coating, the drum mouth speed should not be too fast, to prevent the paint splash, affecting the spraying effect, the action should be light when the mouth is closed, always from the top to the bottom, the card edge skills and brush the same, for different area sizes can use different sizes of the drum.

After the rolling brush is completed: stand the roller upright on the table or the ground, with the other hand against the outer cover of one side, remove the rolling sleeve from the support, and clean the roller. Remember to clean the roller brush with running water when it is still wet, and place it in a ventilated place to dry, so as to continue to use it next time.
