When painting murals with wall painting brushes, mastering the correct usage skills is crucial for creating beautiful and long-lasting works. Here are some key usage tips:
First, choose the appropriate tools
Brushes and brushes:
Brushes: Prepare brushes of different sizes and shapes to meet various painting needs. Large brushes are suitable for filling large areas of color blocks, while small brushes are used to outline details.
Brush: It is used for large areas of coloring and can improve the efficiency of painting.
Pigment
Choose high-quality and environmentally friendly acrylic paints. Acrylic paint dries quickly and has good water resistance, making it suitable for wall painting.
Prepare paints of various colors according to the theme and style of the mural.
Other tools
Palette: Used for mixing pigments.
Spray gun (optional) : Used for creating gradient effects or laying large areas of base color.
Pigment blending agent (optional) : Used to adjust the viscosity of pigments.
Second, prepare the wall surface
Select location
Take into account factors such as the orientation of the wall, the surrounding environment, and the usage function. Avoid choosing walls that are prone to moisture, such as those near bathrooms or kitchens.
Wall treatment
Make sure the wall is clean, smooth and dry. Use a scraper to smooth out the peeling part of the wall plaster. If necessary, sand it.
If there is powder on the wall, you can roll a coat of interface paint to solidify the powder.
Third, painting techniques
Determine the theme and sketch
Determine the theme of the mural based on the function of the space where the wall is located or personal preference.
Gently sketch on the wall with a pencil or charcoal to determine the positions and proportions of each element.
Coloring techniques
Color mixing: Pour the paint onto the color palette and mix it as needed. Make sure the pigment is thoroughly mixed evenly to prevent color sedimentation.
Coloring sequence: Generally, start with light colors and gradually transition to darker ones. After each use of a new color, rinse the pen with clean water to keep the paint pure.
Large-scale coloring: Use a board brush or spray gun for large-scale coloring. The color should be mixed evenly at one time to prevent slight deviations in color mixing from causing inconsistent colors in the picture.
Layering coloring: Apply colors in sequence from the most to the least. During the coloring process, apply small amounts multiple times to give the mural a sense of layering.
Outlining and detail depiction
Outlining: Use a fine and pointed brush for outlining, paying attention to the smoothness and accuracy of the lines. Referring to the central brushstroke technique in calligraphy, hold the brush steady and slowly lift it straight up.
Detail depiction: After the base color is completely dry, use a small brush to draw details such as the expressions of characters and the texture of animal fur.
Use a zero line pencil: For very fine details, a zero line pencil can be used for drawing.
Light and shadow processing
Observe the position and intensity of the light source, and express the three-dimensional effect and texture of the mural through the contrast of light and shade and color changes.
Gently blend at the junction of light and shadow to allow the colors to transition naturally.
Special effect processing
Antique treatment: Gently scrape off some of the pigment with a scraper or sandpaper to simulate the effect of weathering and peeling, enhancing the layering and texture of the mural.
Aging treatment: Use tools such as toothbrushes to age the picture, further enhancing the retro feel of the mural.
Fourth, post-processing
Inspection and Correction
During the painting process, constantly check the overall effect of the picture and make necessary corrections and adjustments.
After the drawing is completed, a comprehensive inspection should be carried out to ensure there are no omissions or areas that need adjustment. Check if the picture is harmonious, if the color tones are consistent, and if there is any sense of dirtiness or disorder.
Drying and protection
Let the mural dry fully. Acrylic pigments usually take several days to dry completely.
Apply a protective coating, such as varnish, on the surface of the mural. Varnish can protect murals from the erosion of dust and stains, and at the same time enhance the gloss of the murals. Pay attention to choosing environmentally friendly and transparent varnish.
Fifth, Precautions
Safe operation
When painting murals at heights, make sure the scaffolding or ladder is stable and wear a safety helmet and protective equipment properly.
When using electric tools such as spray guns, pay attention to electrical safety.
Environmental protection and health
Choose environmentally friendly pigments and tools to reduce pollution to the environment.
Maintain a good ventilation environment during the painting process to avoid inhaling harmful gases.
Save tool
After painting, clean the brushes, palettes and other tools in time to keep them clean and dry for the next use.
By mastering the above skills, you can better use wall painting brushes to create beautiful and long-lasting mural works. By constantly trying and adjusting in practice, you will be able to create more unique and expressive works.
