Repeated alteration will also appear oil absorption phenomenon, which is related to the performance and quality of the pigment dryer. Therefore, contemporary painters often use one-time painting method, starting from the local, and gradually paving the picture with color. Need to adjust the color layer dry after painting. However, if it is necessary to spread large color blocks, turpentine is generally used to dilute the pigment and then apply it thinly, and then paint it by spreading color locally after drying.
If the painting time is concentrated on the way of sketching, the picture needs to be adjusted repeatedly, and the oil absorption phenomenon will inevitably occur. It is recommended to use a polishing agent to deal with it.
The polishing agent is made of synthetic resin and volatile solvent, can make the color layer to restore the original luster. The method of spraying or brushing directly on the oil-absorbing color layer can play a role in polishing, polishing agent can not be coated too much, because any oil will damage the luster of the pigment. The polish also softens the surface oil film. Before laying the new color layer, apply a polish to the dried color layer to bond the old and new color layers together. Mr. Quanshan Shi used a moisturizer to connect before the dried large tone length was deeply shaped. Painter He Duoling directly dipped flaxseed oil with a clean brush and applied it on the dry picture to connect the new color layer. When using linseed oil as a polishing agent, be sure to absorb the excess oil with soft paper or cloth with strong water absorption after coating, and the thinner the retained oil layer, the better.
Garlic juice has also been used by painters to polish. The method is: cut the garlic and rub the oil-absorbing part of the picture with the cut surface. Garlic juice has a certain dissolution and recovery effect. This method is simple, but can only be used for small parts, because of the pungent breath, has been rarely used by the painter.
