In the renovation process, the paint is not a small project, seemingly simple painting or spraying construction, in fact, a wide range of aspects to pay attention to. In particular, the wall is often a large area of ​​paint, once the substrate has not yet been cleaned, or improper paint brushing techniques, it will easily lead to foaming, peeling, peeling, etc. of the paint, which not only loses the appearance but also may cause inconvenience to life. . Then, the next Xiaobian editor painter acceptance.
Painter Acceptance Appearance Acceptance
The appearance of the wall paint affects the appearance of the home as a whole, and care must be taken when checking to ensure that there is no problem with its appearance.
Appearance acceptance of wall paint mainly relates to whether the color is uniform, no color difference, whether the wall cracks, powder, bottom, leak brush and so on.
No obvious color difference, pan-alkali, back color, brush pattern After the paint on the wall paint is dry, it is checked by the method of visual inspection and hand-feeling under the natural light; stand 1.5m away from the wall and check to see if there is trachoma, bite color, Flow drop, color, bottom, etc.; connect the light bulb with a wire, the light bulb is ten centimeters away from the wall, check it along the wall.
No powder, wave, brush and other phenomena
No significant trachoma, flow drop, crease, splash
Doors, windows, lamps, furniture, etc. are clean without traces of paint
Acceptance of painter acceptance of flatness
It is also very important to check whether the wall paint is smooth or not. Acceptance of the flatness is mainly through the inspection of the wall angle deviation and the vertical flatness of the wall. Through these two checks, the acceptance of the wall surface is smooth.
Corner deviation check: Use the multi-functional inner and outer right angle detection rule to detect the deviation of the right and left (yin and yang) right angles of the wall surface. When in use, push the open angle pointer box downwards. When the pointer is in the zero position, the right angle is 90 degrees, and the deviation value is direct reading, and each square is 1 mm. The wall surface deviation of ordinary wall paint is 4mm.
Wall verticality level inspection: When using the vertical inspection ruler, the left side of the inspection ruler is close to the measured surface, and the pointer is observed. The indicated scale is the deviation value. The vertical deviation of the wall paint wall is generally 5mm, and the horizontal deviation is 4mm.
Painter Acceptance Mistakes
The more careful you are when checking the wall paint, the better, but you must also avoid going into the acceptance error. Let's take a look at the common pitfalls in the acceptance of wall paints.
Misunderstanding 1: The hand touches the powder and has quality problems
When checking the wall paint, you usually touch the wall with your hand. Sometimes when the hand touches the wall, many particles will fall off. At this time, many people think that it must be a problem with the paint or construction. However, powder off the wall does not necessarily have to be a problem with the paint.
During the construction process, dust will adhere to the wall. After the construction, the powder will fall off. In fact, these are just dust, and they can be solved simply by wiping them off with a clean towel or tweezers.
Myth 2: The smoother the wall, the better
Wall paint construction generally adopts two methods: roller coating and spraying. The smoother the spraying construction, the better. However, for roller coating construction, roller-printed walls will always have roller stamps. If the wall is particularly smooth, it may be caused by adding too much water to the paint, which will instead reduce the coating's adhesion and reduce the paint's ability to protect the wall. After the roll coating is applied, look at the knurled print on the wall for evenness and detail.
Paint construction process
1, paint materials must be qualified, must use high quality paint. During construction, first clean the site, minimize human activities and dust processes.
2, pay attention to check the cleaning of the grass-roots level, can be used 400# sandpaper lightly polished surface burr, clean with a clean towel, check the panel surface for any stains, damage can be used.
3, after the substrate is cleaned, putty on the transparent, according to the type of panel, brush or direct squeegee, transparent putty squeegee 2 times, painted 4 hours after the dry grinding, putty thin and uniform as well.
4, putty polished, transparent primer, transparent primer and special clear transparent bottom and curing agent, thinner ratio of 1:0.3:0.8 to 1. The transparent primer should be brushed or sprayed with 200# filter before use and brushed twice. After 4 hours of drying, polish with 400# sandpaper.
5. When spraying process is adopted, the site should be cleaned. The ground should be sprayed with a small amount of water to prevent dust and spray evenly.
Editor's summary: About the painter acceptance is introduced here, and I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
