In simple terms, the mushroom stone is a mushroom-shaped rock mass formed by wind erosion of isolated protruding rocks, also known as stone mushrooms and wind mushrooms. This material is still very good as a decoration. As long as it is used well, there must be eleven impressive scenery lines. If the exterior wall is made, it can still play a very good decoration. Then, how to do the mushroom stone exterior wall paving operation process ? Today, we will come to understand with the editor of FABULOUS Group.
The base treatment of the outer wall surface→hang vertical, set square, find the rules→ reinforce, wipe the bottom mortar→→spring line, grid, stick grid strip, drip strip→ wipe sticky stone, mortar, sticky stone→ put gravel Tap it firmly and flatten it with an iron trowel → lift the ruler (or strip) → repair the black edge → joint → watering and curing
1. Process: You must make a sample plate first, and after the appraisal is qualified and the construction method is determined, then a large area can be constructed to treat the base layer → wipe the leveling layer → arrange the bricks, divide the grid, and spring the line → paste the mushroom stone → joint → clean the surface.
2. Grassroots treatment: clean up the impurities on the surface of the grassroots that partially protrude from the wall before construction.
3. After the substrate is processed, apply a leveling layer, the leveling layer is 1:3 cement mortar. The allowable deviation of the surface flatness of the leveling layer is 4mm, and the allowable deviation of the verticality of the elevation is 5mm.
4. Brick arranging, grid division, elastic line: The width of the brick gap is 8mm in principle, and the grid and brick arrangement must use whole bricks. For the parts where the whole brick cannot be used, try to adjust the gray seam, but it is impossible to adjust it. Use the whole brick cut and place it in a place that does not affect the appearance. The horizontal seam between the building and the building should be intersected, and the elevation should be controlled well.
5. Paste mushroom stone: The pasting should be done from bottom to top, and the bonding thickness should be 4-8mm. Before the initial setting of the bonding layer or within the allowable time, the position of the tile and the width of the joint can be adjusted to attach the line and strike it firmly; after the initial setting or after the allowable time, it is strictly forbidden to vibrate or move the tile. At the external angle, to ensure that the external angle intersects at 90 degrees, the internal angle adopts the method of large and small.
6. The jointing should be carried out according to the material and depth required by the design. The jointing should be continuous, straight, smooth, free of cracks, and no hollowing; the jointing should be carried out in the order of horizontal first and then vertical, and the jointing shall be made of circular arc shape with steel bars.
7. After the surface is dry and the cement slurry is fast-drying, wipe it again with dry cotton yarn, and then rinse it off with clean water.
