2. After the substrate is dried, apply canvas paint again. This is a white acrylic emulsion, which is insoluble in water and other liquids after drying.
3. After the first coating is dried, brush the second coating. If you want to draw a plane effect, the canvas is ready and can be used after drying. Oil painting will present a plane effect with high color purity.
4. If you want to make the picture completely shiny and bright without oil painting, or draw traditional classical oil painting, you can paint the canvas base again after the second paint drying, and you can use it after it is completely dried. Oil painting will present a bright and lively effect, which is the ideal effect pursued by various classical and academic painters.
Extended data
The basic point of manual production:
1, the canvas should be fixed straight and taut, and all around it should be fixed on the board or frame with dense nails; You can brush the cloth around with glue first, and then harden it after drying to reduce bending and oblique deformation;
2. Scrape the primer, the primer is not mixed with water or very little water, and the thin scraping method is used for many times, and each layer should be scraped evenly. Seal the grain pores, and there is no bright light point under the light. Sometimes hair will stand up and need to be repaired and polished.
The force should be light, fast and even. Excessive local force or uneven scraping of glue, or too much water will penetrate into the back to form a thick hard spot, and the glue will blister and bulge after drying. If the force is too great, the blade will be tightened and fixed.
3. Brush the substrate. After the canvas is blocked by the bottom, you can brush the bottom material, and you can brush it evenly for many times until it turns white.
4. Foundation thickness and flatness. The thickness of the handle is controlled by the amount of scraping glue, and the bottom surface is polished smoothly. Painters like the feeling of being as smooth as an egg skin, but not greasy or dry.
