I. wall tiling

basic requirements

wall tiling must be constructed after the acceptance of the base course. The specification, color and pattern of decorative panel (brick) shall be consistent and meet the design requirements. The inlay shall be firm, and the surface color shall be basically consistent, flat and clean, without missing and wrong pasting; The wall surface should be free of hollowing, with uniform gaps, straight edges, and no cracks, corners, missing edges, etc. each wall should not have two rows of non integral bricks, and the width of non integral bricks should not be less than one third of the original bricks. The interface between toilet, kitchen and other rooms shall be treated with waterproof treatment, and the performance of waterproof materials shall meet the requirements of current national standards

quality requirements and inspection methods

the quality requirements and inspection methods of wall tiling engineering should comply with the provisions of table 7. The installation quality, surface quality and hollowing shall be checked in full, and the rest items shall be measured at random at two places in each room, taking the maximum value

wall fitting engineering quality requirements and inspection methods

serial number project quality requirements and allowable deviation inspection methods

1 installation quality and surface quality meet the requirements of 8.1.1 visual inspection and hand feeling inspection

2 hollowing * it is not allowed to tap with a small hammer

3 surface flatness ≤ 2.0 mm 2m guiding rule, wedge feeler gauge measurement

4 perpendicularity ≤ 2.0 mm 2m guiding rule measurement

5 internal and external corners squareness ≤ 2 0 mm right angle inspection ruler, wedge-shaped feeler gauge measurement

6 joint height ≤ 0.5 mm steel ruler, wedge-shaped feeler gauge measurement

7 joint straightness ≤ 2.0 mm 5m stay wire (less than 5m pull-through line), steel ruler measurement

8 joint width ≤ 1.5 mm steel ruler measurement

* the hollow drum at the corner of a single brick is less than 10% of the area of the wall brick, and each room does not exceed 5% of the total number. It can not be used as a hollow drum meter (5% of the total number is not amplified by 1.5 times)

II. Ground inlay

basic requirements

ground inlay must be constructed after the acceptance of the base. The toilet and kitchen shall be waterproof before inlaying, and the performance of waterproof materials shall meet the requirements of current national standards. The specification, color and pattern of the decorative panel (brick) should be consistent. The decorative panel (brick) used in the bathroom should be non slip and meet the design requirements. The inlay shall be firm, and the surface color shall be basically consistent, flat and clean, without missing and wrong pasting; The ground gap should be uniform, the periphery should be straight, the brick surface should be free of cracks, corners, missing edges and other phenomena, and the width of the left edge should be consistent. The joint between the ground and the floor drain should be tight. The floor inlay with drainage requirements shall meet the drainage slope requirements without ponding

quality requirements and inspection methods

the quality requirements and inspection methods of ground inlay engineering should comply with the provisions of table 8. The installation quality, surface quality and hollowing shall be checked in full, and the rest items shall be measured at random at two places in each room, taking the maximum value

quality requirements and inspection methods of ground inlay engineering

serial number project quality requirements and allowable deviation inspection methods

1 installation quality and surface quality meet the requirements of 8.2.1 visual inspection and hand feeling inspection

2 hollowing * it is not allowed to tap with a hammer

3 surface flatness

(except for slope requirements) ≤ 2.0 mm 2m guiding rule, wedge feeler gauge measurement

4 joint height difference ≤ 0.5 mm steel ruler Wedge feeler gauge measurement

5 joint straightness ≤ 2.0 mm 5m stay wire (less than 5m pull-through line), steel ruler measurement

6 joint width ≤ 1.5 mm steel ruler measurement

* the hollowing of the corner of a single brick is less than 10% of the area of the wall brick, and each room does not exceed 5% of the total number. It can not be used as a hollowing meter (5% of the total number is not magnified by 1.5 times)
