I'm afraid it's another misunderstanding If the wall is too smooth or greasy, the wall will peel easily after painting, which will also affect the decoration effect If the base is too smooth, the correct way is to brush the base with a rigid brush and remove the greasy dirt with solvent Mistake 3: layered latex paint can't be reused If some latex paint is left after decoration, it can be stored in a cool and backlit place after the bucket cover is covered However, after a period of standing, the emulsion paint may be stratified Many owners think that the layered emulsion paint can no longer be used In fact, as the emulsion paint is an aqueous solution, it is normal to have layered phenomenon As long as there is no yellowing, mildew, peculiar smell and other conditions, it can still be used normally after being stirred evenly, without affecting the final coating effect Error 4: touch the wall with white paint and quality problems After finishing the finishing coat, touch the white paint with your hands You don't need to be nervous Most of the "powder" dropped is dust on the wall In the process of construction, a lot of dust will slowly attach to the wall, and similar phenomenon of powder falling may occur after touching with hands Use a duster or clean towel to wipe off the dust, which should be solved If the quality of latex paint is relatively poor, the moisture content is too much, and the emulsion is less After a year or two of the paint, it may appear that the dust is removed with the towel, but even if it is painted, it will not be dropped by hand Mistake 5: the more expensive the emulsion paint is, the better the effect is The wall effect after the construction of the emulsion paint is good Influenced by the quality of the emulsion paint itself and the construction technology, "good horse" also needs to be equipped with "good saddle", so as to give full play to its maximum effect The higher the grade, the higher the content of paint, emulsion and other raw materials, the higher the requirements for the construction process If the construction process does not pay attention, it is more prone to the phenomenon of wall brushes Mistake 6: qualified latex paint is not the same national standard as environmental protection Only latex paint that has passed the national green ten ring certification is the real environmental protection product Mistake 7: the number of scrubbing resistance index high wall surface can be scrubbed at will with towel The number of scrubbing resistance of latex paint is tested with a special machine brush on the paint surface, rather than the test result with a tool made of towel If the towel is rubbed as hard as clothes, the paint film may be scratched, and even the latex paint with a high number of scrubbing resistance may also be powdered Myth 8: Although emulsion paint is a kind of water-based paint with excellent environmental protection performance, many owners still like to open doors and windows after use, one is to speed up the drying of the wall, the other is to disperse the peculiar smell of the paint It seems like killing two birds with one stone, but is this really right? It's not the case Especially in the northern dry areas, if the paint drying time is too fast, the latex paint quickly loses water in a short time, which is easy to cause wall cracking, and finally has to be reworked The correct way is to open a small gap in the window to ensure the indoor ventilation On the premise of this, it is advisable to let the wall completely dry in 1-2 days The above is Xiangxiang editor's explanation of the mistakes in the use of latex paint, hoping to help you with your home decoration!
