To ensure the durability and water resistance of
Hand-painted wallpaper, measures need to be taken from many aspects. First of all, in the choice of painting materials, the use of good quality, high durability of the pigment is crucial. For example, choose a professional acrylic pigment, which has good light resistance, weather resistance and chemical stability, is not easy to fade and discolor, and can maintain the bright colors of the murals for a long time. Compared with watercolor pigments, acrylic pigments will form a tough film after drying, which has a certain waterproof and wear resistance.
Before painting, the treatment of the wall is also very critical. Make sure the walls are flat, dry and clean, free of dust, oil and loose materials. The wall can be polished and primer treatment, primer can enhance the adhesion of the pigment and the wall, and play a certain sealing role to prevent the moisture and alkaline substances of the wall from leaking out, affecting the durability of the mural. Choosing the right primer is also important, and it is generally recommended to choose a primer that is compatible with the pigment, for example, acrylic primer if using acrylic paint.
During the painting process, some special additives can be added to improve the durability and water resistance of the mural. For example, adding an appropriate amount of media to acrylic pigments, such as propylene blend or water repellent, can enhance the performance of the pigment. These media can improve the fluidity and adhesion of the pigment, while improving its water resistance and weather resistance. But pay attention to the proportion of additives used, too much or too little may affect the effect of the pigment.
After the painting is completed, the surface protection of the mural is also essential. The fresco can be sprayed or painted with a transparent bedliner or varnish to form a protective film to prevent the paint from being worn, polluted and eroded by moisture. When choosing a bedliner, make sure it is compatible with mural paint and will not cause chemical reactions or color changes. At the same time, pay attention to the construction method and drying time of the protective paint, and operate according to the product instructions to ensure that it can fully play its protective role.
In daily use, attention should be paid to avoid direct contact with a large number of water and sharp objects. Avoid spraying water or placing damp objects, such as wet cloths and mops, near the mural. If there are stains on the surface of the mural, it should be gently wiped with a soft dry cloth in time to avoid scratching the surface of the pigment. Regular inspection and maintenance of the mural, found that there is damage or fading of the situation in time to repair and treatment, in order to extend the service life of hand-painted wallpaper, to maintain its beauty and durability.
