There is a dangerous wall in the family, and the fortune is not guaranteed. The master of Feng Shui said: The decoration of the wall must follow these three steps!

in the process of decoration, people often encounter a problem, that is, when a new wall is built under the design requirements, cracks often appear at the junction of the new wall and the old wall. This is a common problem, so why does the junction of the old and new walls crack?

The decoration is divided into three parts: the top part of the wall, the wall part and the ground part. As a wall decoration, it is the focus of our home decoration. If you want to decorate your home well, you must decorate the wall well. But do you know what should be paid attention to before wall decoration? The master said that if the wall surface is not handled well, it will affect the fortune of our family and the wealth of our family, so we must follow these steps when decorating and building walls at home!

1. Technological process

1. Bricks or blocks: lime-sand bricks and light bricks;

2. Cement: 425(R) ordinary silicon cement is used, and different cement varieties are not allowed to be mixed;

3. Sand: medium sand shall be used, and grass roots and other sundries shall not be contained;

4. water: tap water;

5. Admixtures: Lime plaster is used, which must be cured for at least 7 days before use, and dehydrated and hardened lime plaster is strictly prohibited; All the above materials shall meet the design requirements, and have the factory certificate and test report. Unqualified materials shall not enter the site.

Second, quality requirements

1. Before bricklaying, mortar mixture ratio, technical disclosure and measurement preparation of ingredients have been prepared;

2. When bricklaying, the moisture content of blocks should be controlled. For perlite blocks and ceramsite concrete blocks, it is not necessary to water masonry to ensure masonry bonding;

3, block construction should play the main axis of the building and masonry control sideline, after inspection, before construction;

4. When the horizontal mortar joint thickness of masonry skin brick exceeds 2mm due to excessive floor elevation deviation, fine stone concrete should be used for leveling. It is strictly forbidden to mix broken bricks or use mortar for leveling in masonry mortar, and side bricks are not allowed to be used, and the middle is filled and leveled;

5. The bricklaying project shall be subject to the model first system, that is, the bricklaying of the model wall (room) shall be carried out first, and the construction can only be fully rolled out after the acceptance of Party A, design, supervision and quality and safety departments of the company;

6. quality standard: it should meet the requirements of construction quality technology.

3. Bricklaying construction technology

1. Mixing mortar: the ingredients are weighed according to the mortar mixture ratio provided by the laboratory. In the process of mixing, attention should be paid to the moisture content of mortar and timely adjustment should be made to ensure accurate feeding and the consistency of mortar should be controlled at 7-1 cm;

2. Mortar masonry should be staggered up and down, and the mortar joint built inside and outside should be straight and full, and the fullness: the horizontal joint should not be less than 9%, and the vertical joint should not be less than 8%. The horizontal mortar joint thickness and vertical mortar joint width are generally 1mm, but not less than 8mm and not more than 12mm；;

3. The corner and junction of brick wall should be laid at the same time. For temporary breaks that cannot be laid at the same time and must be retained, they should be built into oblique if, and the length of oblique if should not be less than two-thirds of the height. If it is really difficult to leave a temporary break, a straight if can be left except the corner, but it must be made into a positive if, and the number of Rachel bars should be added to put two 6mm steel bars per 12mm wall thickness, and the spacing along the wall should not exceed 6mm.

4. When hollow blocks are used, blind hole (back cover) blocks shall be staggered, and the bottom of the hole shall be turned upwards to ensure full mortar joint. The lap length of upper and lower skins should not be less than 9mm; Lightweight aggregate block is not less than 12mm, otherwise Rachel reinforcement shall be set in mortar joint;

5. Masonry about 3 meters high from the bottom of beam and slab should be built at least every other day, and the lower masonry should be deformed and stabilized before it is built. Masonry must be tightly squeezed with the bottom of beam and slab, and the horizontal masonry should avoid the application of auxiliary solid small blocks to obliquely build by laying bricks or stones, and the gap should be filled with mortar;

6. In order to avoid uneven deformation or cracks in the wall caused by continuous masonry, the daily masonry height should be controlled. The lime-sand brick should be controlled within 1．8m, the perlite block should be within 1．4m, and the construction height in rainy days should not exceed 1.2m..

There is no small matter in decoration. It takes our heart to achieve water and electricity decoration and design as small as the corners. This is what home improvement means. We must pay attention to these precautions when decorating, so as to ensure that there will be no problems with our furniture, and we can live in our beautiful new home after decoration!
