Common knowledge of coating: causes of color fading and powder loss in coating construction

Core tip: some figures show that 90% of the problems such as color fading, powder falling and color difference after paint painting in the market are caused by improper construction Unscientific treatment of wall base, excessive mixing of paint with water, backward construction tools and poor workers' skills will hinder the effect of paint beautifying wall If you choose home decoration company to brush paint, you must be wary of this phenomenon: the decoration company subcontracts layer by layer, and finally comes to the small construction team to save money by mixing more water If the construction team fails to construct according to the standard water volume, the water volume is too large, for example, 5 barrels of emulsion paint should be used Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: figures show that 90% of the problems such as color fading, powder falling and color difference after paint painting in the market are caused by improper construction Unscientific treatment of wall base, excessive mixing of paint with water, backward construction tools and poor workers' skills will hinder the effect of paint beautifying the wall If you choose home decoration company to brush paint, you must be wary of this phenomenon: the decoration company subcontracts layer by layer, and finally comes to the small construction team to save money by mixing more water If the construction team fails to construct according to the standard water volume, the water volume is too large For example, for a room that should be painted with 5 barrels of emulsion paint, two barrels of paint will be used up, three times of paint will be applied, and only two times of paint will be applied, so the consequences of construction can be imagined, and the coating will be made The number of times of scrub resistance and the decrease of mildew resistance and alkali resistance are as follows: the powder is removed, the substrate is exposed after a little scrub with a wet cloth, the top-grade paint that should be glossy is not glossy and the surface is rough, etc At present, the main factors affecting the coating construction quality in the home decoration market are as follows: substrate treatment: in addition to the selection of qualified putty Besides materials such as powder, adhesive and wall lining, the material of wall base material, flatness and cleanliness of treatment (including removal of old coating film, mould spot, floating dust, oil stain, etc.) as well as the humidity and acidity of wall surface will affect the final coating effect Selection and use of primer: the application of primer can not only prevent the wall from alkali, discoloration, mildew and other problems, but also increase the adhesion between the wall and the top coat, making the top coat film more flat and firm Therefore, the application of primer is an essential link in the coating process of new house The primer should be matched with the top coat, but some decoration guerrillas or fitters who operate illegally often use some inferior primers, or even do not use the primer at all, resulting in paint consumption, paint discoloration, peeling off, chunking, mildew and other painting problems Construction operation: before the construction, whether the paint dilution ratio is proper, whether the mixing is even, and whether the construction technology of the operators is skilled are very important Excessive dilution will make the paint not cover the bottom, powdered, shiny paint will appear loss of light, color and other defects In order to save time and cost, one of the main reasons is that the coating quality can not be guaranteed is that the construction is not carried out according to the specification Construction environment: pay attention to the climatic conditions during construction and the conditions of the construction site, such as temperature, humidity, whether it is windy and rainy, indoor ventilation, and whether the painting surface and tools are clean During construction, after one coating is completely dry (about 7 days in summer, about 15 days in winter, and appropriately extended in wet weather and poor ventilation), another coating shall be applied, and doors and windows shall be opened in the process of construction and drying of each coating to maintain ventilation, otherwise the coating may bulge and pulverize Product features: at present, there are many brands and varieties of interior wall coating in the market The construction characteristics of the product are not understood, and the construction is not carried out in strict accordance with the product construction instructions The construction quality problem caused by it is also one of the problems that can not be ignored For example, excessive dilution causes sagging, blooming and other phenomena, and improper selection of construction technology causes serious brush marks and roller marks Home of coatings is specialized in coatings, diatom
