(1) The uneven screen caused by extrusion, collision without cracks, please spray appropriate water on the back of the canvas. You can put it in the well-ventilated place to dry after the oil painting is level. When using the hair dryer to accelerate the drying time, please don't forget not have the temperature too high. Generally, don't dry under sun.

The simple way is that: clean the cracks with turpentine, level the painting, put a certain hardness of wood under the back of the cracks, then tap the crack from face gently, planish the protuberant corner, then besmear transparent quality latex in the crack and reinforce the color in the obvious crack area, at last polish after drying. This method can be only used to the non-touched texture flat screen. The texture screen can be wiped and then made the glue, polish or fill color. The place where there is color off need to reconcile the large white powder (or lithopone) into paste for filling material, then fill the color.
(3) The repair method for the cracking caused by the collision: besmear latex on the back of the cracking, cut a big piece of linen to paste, level cracking area by using the knives. The screen is flat down the desktop. Iron the linen with an electric iron, be careful not to let the latex paste on the desk. To be flat for drying, then fill the paints in the cracking area. If the cracking is very obvious, it needs to fill material before coloring.
