Marble has been subject to frost, snow, ice, and other attacks all the year round. With the continuous increase in the use of time, the number of cycles experienced by freeze-thaw cycles has increased, and marble finish cracking can easily occur. Due to the poor stone quality of marble, the large number of color patterns, or the improper inlaying, the voids on the walls are kept less and are often affected by various external forces, resulting in irregular cracks in the dark lines of the color lines or other hidden defects. , so what is the marble repair cracks and stone floor repair methods, the following is for everyone. Causes of cracks in Dali (1) In addition to marble defects such as color lines, blind seams, or other hidden flaws, as well as grooving and improperly damaging slots, after being subjected to structural subsidence, compressive deformation and external force, due to stress concentration, when the external force exceeds the strength of the block, it will result in Cracked marble wall. (2) When marble is installed on the outer wall or in close proximity to kitchens, toilets, etc., where the humidity is high, the installation is rough, the grouting of the board joints is not strict, and the eroding gas and air penetrate into the board seams, so that the embedded iron pieces are encountered. Corrosion, resulting in expansion, gives the marble plate an outward thrust and cracks. (3) When the marble plate is installed on the wall surface or the cylinder surface, the upper and lower gaps are kept less. When the structure is subjected to pressure and deformation, the marble facing surface is subjected to vertical pressure, and cracks may also be generated. According to the main causes of cracks, the following points should be taken: (1) When installing marble facings on load-bearing structures such as walls and cylinders, installation should be carried out after the structural subsidence is fixed. At the top and bottom, when installing marble plates, certain gaps should be left to prevent compression of the structure. , The marble bearing is directly pressed and cracked. (2) The joints for installing marble shall be no more than 0.5～1mm, the caulking shall be tight, the grouting shall be full, the blocks shall have no defects such as cracks, missing edges, etc. to prevent the intrusion of erosion gases and moist air; Iron pieces cause cracks in the board surface. After a crack occurs in marble, it needs to be repaired quickly to prevent the stone from falling due to stone cracks, affecting pedestrians, or directly affecting the form and quality of the building. Marble crack repair steps 1) Remove the mortar or other debris from the original marble crack, 3-5mm deep. If it is granite, the width of the gap should be increased to about 10mm. If it is marble, clean the original seam. 2) The marble that is close to the color and pattern of the crack should be smashed with a small hammer. If the stone is a granite, its grain building should be similar to the size of the stone. If it is a single-color stone, it should be powdered. 3) Take appropriate amount of transparent marble glue and broken marble particles or powder, stir well, add proper amount of driers, and stir well, and evenly mix the mixture evenly on the crack mouth. After coating, the crack opening is slightly higher than the marble surface. 0.5mm is appropriate, and it will dry later. 4) The corner polisher shall be equipped with No. 100 resin sand rubber sheet, and the dried cracks shall be slightly smoothed, and then the No. 220 resin film shall be finely ground, and then polished with No. 360 water sandpaper to remove water from the wall or the ground. Clean the stains and then polish them with a horn polisher and polish them with wax. After the gloss appears, continue polishing until it is close to the luster of the original marble. Then use a small amount of polishing wax from the steel wool and polish it by hand until it is shiny. It is exactly the same as the original marble. At this time, the cracks cannot be seen. 5) If there is a pattern in the single-color stone, the pattern is exactly at the crack. In addition to stirring the powder with glue, the toner is also used to match the color of the pattern and is embedded in the seam. Stone floor repair methods and materials 1, on-site observation. In the absence of repair of the stone floor in question before the scene to be observed, to fully grasp the damage and status of the stone, analyze and find the root cause of the problem, at the same time in the surrounding business environment, and the owner to discuss the repair Arrangement of working hours. This helps to submit a full and complete stone restoration report for the owner to confirm. 2. After determining the restoration plan for the stone surface, it is necessary to negotiate with the owner to find an insignificant position to try a piece of ground. In this way, the feasibility of the scheme can be examined. On the other hand, the owner can confirm the repair effect and avoid unnecessary disputes. Trying to do this piece of ground can best observe for a period of time. During this period, attention should be paid to observing the changes in the humidity of the stone, and observing whether the repaired parts are peeled off and re-appear damaged, so that the repair program can be revised accordingly. 3, stone repair and make up materials. DNS Stone Reinforcing Adhesive Series is a kind of polymer resin application material with strong permeability and activity. It is used in the form of AB two-component mixture. The completely transparent and clear water-like liquid is suitable for repairing and remedying various colors of stone materials. After these liquids are smeared onto a stone defect, they penetrate into the defective part of the stone and create a chemical hardening process that hardens into a body with the material of the stone. Because this process runs through various defects in the stone, such as cracks, cracks, cracks, holes and looseness, it will strengthen the loose material and repair these defects. In this way, the stone can not only see the perfect repair effect after grinding and polishing, but the stone still maintains the natural texture. Due to the fact that the stone is damaged, this is basically the same phenomenon. In addition, the DNS stone-reinforced adhesive has good adhesive strength and cloth resistance, so this material is very suitable for repairing the damaged stone floor. Editor's summary: The relevant information about the steps of repairing cracks in marble and stone ground repair methods was introduced here for everyone. I hope this article will help everyone.
