Wall paint construction acceptance points
choose a large area of painted wall paint home installation friends, in the acceptance should focus on checking the wall paint project. Wall paint acceptance must be careful, strict wall paint brush quality, do not wait until after check-in to find the problem. Let's take a look at the main points of wall paint acceptance and some acceptance errors
.
the appearance
the appearance of wall paint affects the overall appearance of the home, acceptance should be careful, to ensure that its appearance is not a problem.
the appearance of the wall paint acceptance mainly involves whether the color is uniform, no color difference, whether the wall has cracking, dropping powder, permeable bottom, leakage brush and so on.
Wall coating appearance acceptance standard Huaihuai and method
no obvious color difference, pan-alkali, recolor, brush pattern In the wall paint paint dry, in natural light using visual and feel method acceptance;
no drop powder, wave, brush leakage and other phenomena.
no significant sand eyes, drops, thrus, splashes.
windows and lamps, furniture and other clean, no paint traces.
is also
to check whether the wall paint brush is flat. Flatness acceptance mainly by checking the corner deviation and vertical flatness of the wall two, through these two checks, to ensure that the wall received is flat.
corner deviation check: the use of multi-functional internal and external right angle detection ruler can detect the wall inside and outside (yin and yang) right angle deviation. When used, push down to open the angle pointer box, when the pointer is at zero, the right angle is 90 degrees, its deviation value read directly, each grid is 1mm. Generally painted wall paint wall deviation value of 4mm.
the verticality of the wall horizontal check: when using the vertical detection ruler, the left side of the detection ruler is close to the measured surface, observe the pointer, the scale is referred to as the deviation value. The vertical deviation value of the wall paint wall is generally 5mm and the horizontal deviation value is 4mm.
acceptance error
the more careful the better when accepting wall paint, but also to avoid walking into the acceptance error. Here's a look at the common mistakes in wall paint acceptance.
1: hand touch powder has quality problems
check the wall paint, generally touch the wall with your hands. Sometimes the wall will drop a lot of powder after touching the hand, this time many people think it must be paint or construction problems. But wall drops don't have to be paint problems.
in the construction process, there will be dust glued to the wall, after the construction of the hand touch will appear the phenomenon of powder. In fact, these are just dust, as long as a clean towel or duster wipe off can be solved.
2: The smoother the wall, the better
wall paint construction generally uses rolling and spraying methods, spray construction of course, the smoother the better. But rolling construction, the general rolling wall will be left with a roller print.
if the wall is particularly smooth, it may be caused by adding too much water to the coating, which will reduce the adhesion of the coating and reduce the coating's ability to protect the wall. General roll coating construction, look at the wall left a rolling flower print uniform and detailed can be.
the main points of acceptance of wood
wood lacquer acceptance is the home acceptance to focus on the project. According to a certain standard Huai, the method of the wooden furniture paint inspection, timely detection of problems in order to rectify. Because wood paint brush mainly has transparent paint wood pattern effect and color paint effect two, according to the effect of different, acceptance also has nuances. Here's a look at some of the key points from the acceptance of wood lacquer.
clear wood grain is
for wood products that make wood paint transparent. After the transparent effect of the wooden furniture painted, the texture of the wood is not covered, the natural texture of the wood can also be displayed.
For owners who require a wood grain effect, check that the wood paint surface is clear, that the brown eye is flat, and that some other defects in the wood are well covered.
paint color uniform color-free
this is for the color paint effect of wood products. After painting the wood furniture with the color paint effect, the pattern of the wood is obscured, showing the color of the color paint.
the wood paint effect in the acceptance, to see whether the paint is uniform, whether there is a color incosistency, the paint surface is required to have no brush marks.
paint surface smooth flat, saturated plump
acceptance can be lightly touched by hand paint, feel smooth, thickness is uniform. High-quality wood lacquer paint surface should be smooth and flat, no rough and grainy, uniform thickness. Also check whether the paint saturation and fullness are good. Look at the gloss of the paint and carefully see if the reflective light is uniform.
paint surface without whitening, granulation, pinholes, cracks and other defects
For example, the surface of the paint film appears the size of particles, the color is whiter than the original, white foggy, appears such as needle-sized small holes, cracks in the surface and so on. At the time of acceptance, special attention should be paid to the absence of these more serious problems.
S side, bottom surface and other brushless paint is not in place
in the wood paint acceptance, many people may pay attention to the furniture surface of the wood paint painting effect, quality, and often ignore the furniture side, back, inside, bottom and so on easy to paint not in place. Therefore, in the acceptance of the time, we must pay attention to this. If the bottom surface and so on can not really see, you can use the reflection of the mirror to observe.
check the decorative line, color split line is straight
do mixed paint furniture, when accepting wood paint, pay attention to check the decorative line, color split line is straight. The two-color paint junction of qualified wood paint is straight in color, with a vertical line, almost without deviation. The color-split line between the two colors twists and turns, is extremely unsystacuous and unqualified. The inspection can be measured by pulling the wire, the error must not be greater than 1 mm.
Check whether the hardware adjacent to the woodware is clean
Wood lacquer construction, if not done with the wood adjacent hardware, glass, walls, floor and other protection, these objects and parts are easy to be contaminated with paint. Therefore, when accepting, in addition to checking the wood itself, but also to check the wood adjacent objects and parts are clean, whether contaminated with paint.
Summary: Wall paint acceptance can use light bulbs and rulers to determine whether there is color difference, cracks and flatness, and wood paint acceptance is mainly with the eye to observe the hand caressing the paint surface, to see if its surface is smooth, thickness is uniform. Paint construction acceptance although complex and cumbersome, but in order to ensure the quality of its painting, we still have to pay more attention.
