After a period of use of stone in hotels and high-end hotels, the surface will be darkened. Due to the busy business of hotels and high-end hotels, there is not much time for stone care.
Under normal circumstances, you can use Dolby 2000 #3000# brightening hardener to deal with. Dolby 2000#3000# Adds a hardening agent to form a hard surface, which increases the hardness of the stone and increases the gloss of the stone. You can walk for about 1 hour after applying, and you can drive after 24 hours of drying. The effect is better after the second application, but do not apply too thick for the first time. After a large area is completed, it is cleaned and cleaned with water, and then a bright and radiant crystal surface effect appears.
If the stone is severely worn and the surface is shiny, it needs to be polished with Dolby polishing powder + f66 true light agent. The polishing powder contains fine particles of an oxidizing agent such as alumina or tin oxide, and its main component contains a surface oxidation active and does not contain an acid. Hand-polished is suitable for the bathroom and kitchen area of ​​the hotel building, while the machine polishing is used for large areas of matte surface. The specific practices of Hefei stone manufacturers are as follows:
1. Ensure that the surface is dry and not protected by a protective agent. If necessary, use a neutral stone cleaner to clean the surface to make the stone surface clean and dry, ready for the next polishing.
2. Use a spatula to remove the polishing liquid onto the surface of the stone, then sprinkle the same amount of polishing powder, using half a spoon of polishing powder and polishing liquid on each square foot (0.093 square meters) of stone surface.
3. Polish with 100-140 lb ground grinder or hand grinder (1500-2500 rpm) with white nylon pad and wool pad for polishing on the floor to be treated. Polish 6-8 square feet (0.56 - 0.74 square meters) each time until its brightness is restored. Generally one can (0.5kg) can be polished to 200 square feet.
When there are several cases of lesions, they must be treated with different stone conservation methods:
Rust
The key to preventing rust spots is to perform effective surface treatment after stone processing to prevent the iron-bearing minerals from oozing out of the surface after oxidation. Generally, oily stone protectants are used.
Water spots, wet marks
The prevention of water spots is mainly to inject resin to make the stone waterproof, to prevent the moisture in the air from coming into contact with the internal materials of the stone or cement, and to reduce the chemical reaction conditions.
The treatment of water spots mainly uses the infiltration dye to change the color of the original stone. The "wet marks are not dry" can be regarded as a major problem in the international stone conservation.
Baihua phenomenon, commonly known as tears
The prevention of Baihua phenomenon is mainly to treat the stone with six sides after the stone processing with osmotic protective agent.
The main problem of dealing with Baihua is to rinse the surface of the cleaned stone with water to make it neutral. After drying, the surface and joints of the stone are cured.
