Decoration is a technical work, painting is a very important link in the decoration process, as the saying goes, three points of wood paint, visible paint on the importance of home decoration, as long as we master some decoration skills, we can create a beautiful home. So what are the precautions for painting? The following to explain to you, I hope to help you.
Paint the sketch
1, the impact of biting bottom adhesion paint brushing should pay attention to
Bite the bottom effect of adhesion between coatings, so that the paint film shift, uneven thickness, even in the surface of the paint indentation phenomenon, mainly because the former process of the formation of the paint film can not withstand the solvent used in the coating after the process of etching. During construction, pay attention to the matching use of various paints, such as the matching of top paint and primer. If not matching paint, can be used between two kinds of paint can be matched with two kinds of paint as isolation sealing layer, at the same time brush after a paint must wait for the first paint film dry, pay attention to not in a place repeatedly brush.
2, paint film wrinkle uneven coating is not easy to be too thick
Make the paint film produce many twists and turns, uneven phenomenon, mainly because the paint film surface dry not caused by, or the coating is too thick, the paint film viscosity is too large, and in the sun exposure can lead to dry inside the table. Common measures are to make the paint viscosity is appropriate, each layer of paint film should not be too thick, paint bristles should not be too long and soft, while avoiding direct sunlight and strong wind blowing.
3, paint film spots dry after decontamination and paint
After brushing the head of the paint, if the paint film is too smooth, or there is moisture, dust, greasy, etc., so that the paint film after the brush can not adhere to the local place, the formation of spottled phenomenon. The method of prevention and control is to wipe the oil on the surface with soap after the first paint drying, and then gently polish and wipe the surface with fine wood sandpaper, and then brush the paint after drying.
4, paint film white color loss to keep dry effect
Nitrocellulose lacquer finish construction in rainy day, the wet season, white occur often. When the coating turns white, it forms an opaque or translucent milky mist. Color paint coating after white, will make the color paint lose bright color.

Prevention and control measures: indoor must be kept properly dry, rainy days should be closed doors and Windows construction, if the temperature can not be controlled, can add appropriate moisture-proof agent in the paint, generally add 10%-20% butanol moisture-proof agent in banana water. In addition, the baking lamp can be used to bake the white place, until the white paint film moisture completely evaporated, and then coated with a layer of moisture-proof agent coating.
5, color uneven how to do before brush paint mix
If the paint is composed of two or more different colors, the coating film may produce uneven color phenomenon. Before painting with a wooden stick will be mixed paint, brush if you find uneven paint film color, you can first dip the paint brush into some uniform paint and then paint film uneven place, with the brush with change, to be appropriate to brush several times.
6, there are particles on the surface of the paint film grinding again and then paint
The surface and grass-roots cleaning is not thorough, there is dust, the construction is not clean, the dust falls on the surface of the uncured paint; Paint without filtration, self precipitation, caused by impurities. In order to avoid surface particles of paint film, to keep the room clean, dust free, paint bucket, brush to clean. If the surface particles, sandpaper can be used to polish the paint again
7. The phenomenon of stream hanging is very common and easy to deal with
Often occurs in the vertical surface or vertical surface and horizontal surface contact (angular), flow hanging at the paint film thicker than other surfaces. It is due to excessive lacquer release and excessive amount of paint at a time. The corresponding countermeasures are: when brushing, to grasp the thickness of the coating, brushing quickly and evenly, if the local flow is found, immediately use the brush to clear, remove the excess paint, brush hardness should be appropriate, bristles should not be too long and soft.

For spraying (spray gun distance finishing surface is generally 15 cm – 25 cm, the air pressure of the air compressor should be 0.2Mpa – 0.4Mpa), if it is found that the flow hanging, such as paint film dry with sandpaper grinding, and then finish.
