What are the construction technology and requirements of gypsum line?

6.6. 1 gypsum line installation construction technology. Raw material quality requirements

6. 1. 1. The linear whiteness is subject to the samples provided.

6. 1.2. The gypsum line must be reinforced with fiber, and the thinnest part shall not be less than 6MM. 6. 1.3. The edges and corners of plastering line should be clear, without burrs and edges, and the arc should be smooth and without wavy lines. 6. 1.4. The curved ceiling and wall parts must be processed into curved plastering lines according to the actual samples on site. 6. 1.5. 108 glue, gypsum powder 6.2. Construction requirements 6.2. 1. Elastic curve

According to the horizontal line of the wall, the plastering line pops up at the lowest point of smallpox, and the horizontal line of the wall is installed. According to the vertical plane of the wall, the plastering line and ceiling installation line will pop up at the most prominent part of the wall. If the deviation of wall ceiling is too large, which brings difficulties to the installation of gypsum line, it should be put forward at the time of pay-off delivery, and mud repair should be arranged. paste

Paste the plastering line with the adhesive made of 108 glue and gypsum powder, and paste it according to the wall line and ceiling line, and fix the plastering line with self-tapping screws. Each plastering line interface must adopt a 45-degree oblique interface. On the same day, when pasting the plastering line outside the lamp trough, the pasting position must be made at the plywood base in advance to ensure that the plastering line on the lamp trough is close to the plywood and straight. 6.2.3.Repair

The plastering seams and flat-fell seams of the Yin and Yang corners must be carefully repaired, so that they are angular and can't have the phenomenon of falling corners.

6.3. Installation Quality

6.3. 1. It shall be firmly bonded with the wall and shall not be cracked with the ceiling of the wall. 6.3.2. Seen from the side, the plaster line should be straight without wavy lines.

6.3.3. The installation levelness error of gypsum line is less than 2MM, and the length of gypsum line is 5M. 6.3.4. Plastering line flat-fell seam is smooth, and there is no obvious stitching trace. 6.3.5. The edges and corners at the junction of Yin and Yang shall be clear, and there shall be no corner drop or corner rot.

6.3.6. When the angle of plaster line is 45 degrees, the included angle is 90 degrees, except the angle required by special design. 6.4. Visual requirements:

6.4. 1. The surface shall be smooth, clean and consistent in color;

6.4.2. Check the straightness error with a two-meter feeler gauge within 65438±0mm; 6.4.3. The angle of Yin and Yang should be straight and complete, and the vertical error should be within 0.5mm. ..

First of all, we should do a good job at the grass-roots level to ensure that the walls are inspected and decorated with rulers. Secondly, the top surface of the wall is scraped twice, and the surface is flat and there is no protrusion or depression. Only in this way can the early quality of gypsum line construction be guaranteed. During construction, the front should be constructed first, starting from the front. Only in this way can we ensure that there are fewer joints in the front and put less than half of them in an inconspicuous place. During construction, it is required to stick and adjust quickly, and adjust while fixing. After adjustment, the place to be repaired should be filled in the shortest time, and the place to be cleaned should be cleaned in place, and then cleaned with clear water to ensure that the decorative surface is clean and tidy (because the setting time of gypsum is short, hands and feet must be fast, otherwise it cannot be cleaned after adjustment).

For the most important part of plaster line construction, the masters of Chengdu Longfa Decoration think it is the corner and joint construction part. From this point, it is easy to find that the connection part of plaster line must be leveled with plaster before connection. Pay attention to whether the patterns are aligned and the heights are consistent enough when connecting. Secondly, the plaster line should not follow the wall as a whole, and the lower part needs to be straightened with plaster. Finally, the gypsum on the surface of the gypsum line should be cleaned with clear water to avoid later cleaning.

The final construction step is the restoration project, which needs to be completed by the painter. After the plaster line is pasted, the painter will repair the joint part of the plaster line to make the joint part fade, so that the edges and corners are not so obvious, which will easily affect the overall effect at first glance. Therefore, a small plaster line can only play its ultimate role when it is well constructed, and it is better not to use it if it is not used well.
