problems in decoration Today, Xiaobian will take you to take stock of 8 crimes of paint, and don't be cheated by "paint" 1 If the original paint is glossy or powdery, the new paint will not stick firmly on the surface Or it may be rotten wood or rusty metal, or peeling due to poor paint quality [solution] for small area of paint peeling, first polish with fine sandpaper, then apply putty, brush primer, and then paint again The paint must be scraped off and repainted in case of large area peeling 2 One of the conditions of paint blistering is that there is moisture infiltration under or behind the paint layer Once the paint is exposed to the sun, the moisture evaporates into vapor, and the paint will be blistered The second situation may be the cracking of wood grain, with a small amount of air inside Once exposed to the sun, the air expands and the paint skin bulges [solution] in view of the former situation with water, the bubbling paint can be removed with hot air spray gun, the wood can be dried naturally, then the primer can be applied, and finally the whole repair surface can be repainted In the case of no water in the latter, first scrape off the blistered paint skin, then fill the cracks with resin filler, paint again, or without filler, after scraping off the paint skin, directly apply microporous paint 3 Cracks appear on the surface of the paint Most of the reasons are that the incompatible paint is used The coefficient of expansion of the upper and lower paint is different [solution] in most cases, chemical paint remover or hot air spray gun shall be used to remove the paint and then paint again If the fracture range is not large, at this time, it can be moistened with sand grinding block or dry and wet sandpaper to remove the broken paint After the surface is polished smooth, apply putty, brush primer and paint again 4 There are many reasons for the stain on the paint surface For example: the water in the emulsion paint dissolves the substance on the wall and rusts the paint surface, the wall surface rubbed with steel wool will produce rust spots, and the leakage of concealed pipes in the wall will produce stains, etc [solution] in order to prevent stains, a layer of primer containing aluminum powder can be applied first If there are stains, the latex paint at the spots can be removed first, and then the primer containing aluminum powder can be applied again 5 The reason for the loss of luster is that the primer is not applied, or the primer and inner layer paint are directly applied with varnish before they are dry As a result, the varnish is absorbed by wood and loses luster The poor quality of varnish is also a reason [solution] grind off the old paint with dry and wet sandpaper, brush off the dust, wipe the surface with a clean and wet cloth, and then brush the paint again after it is completely dry Special attention should be paid to the fact that when the paint is applied in a low temperature environment, the paint film may lose luster after drying 6 Dark spots appear on the surface of painted wood, which may be caused by the fact that the knots are not sealed before painting, and the resin seeps out of the knots when the knots are heated by the sun [solution] at this time, you can use a scraper to scrape off the paint, and then use fine sandpaper to polish until the wood joint is exposed, seal the wood joint with the sealing paint, and then paint again after it is completely dry 7 The wrinkle of the paint film is usually caused by painting the second time before the first time is dry At this time, the solvent in the lower paint will affect the upper paint film, making it wrinkle [solution] in this case, chemical mercury remover or heating method can be used to remove wrinkled paint film and repaint Remember, you must wait for the first coat to dry out before you apply the second coat 8 The surface of a new paint is rough, usually because the brush is not clean or polluted by the surrounding environment It may also be that the paint is mixed with paint skin, which has not been precipitated and filtered before use, or the paint has been stained with dust when it is not dry [solution] in order to prevent the above problems, clean paint brush and paint barrel must be used Be sure to filter the old paint before use In addition, when the paint is not dry, the surface should be covered with a cover or cardboard If the paint surface is rough, after it is completely dry, polish it with dry and wet sandpaper, wipe it clean, and then brush the paint again Pay special attention to that the paint brush must be clean [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
