Stone maintenance and renovation methods are as follows:
1, comprehensively clean the ground, and clean it with a clean mop, so that the ground is free of sand and impurities.
2. After the overall cleaning of the stone surface is completed, repair the small broken points and crevices on each stone with marble glue.
3. After the marble glue is dried, grind the whole ground with a grinder, and grind the whole horizontally, focusing on grinding the caulking glue between stones (diagonal between stones) and near the edge of the wall, decorative modeling and special-shaped modeling, so as to keep the whole stone ground flat.
4. After polishing, treat the water on the ground with water absorbent, and blow dry the whole stone floor with a hair dryer. If time permits, natural air drying can also be used to keep the stone surface dry.
5. While spraying K2 and K3 evenly on the ground, polish them with a marble polisher, sprinkle K2 and K3 with the same amount of water with a cleaner with a red cleaning pad, and polish them with a 175 rpm ground polisher with a load of 45KG. The surface effect formed by the crystallization of crystal plane substances on the stone surface is caused by heat energy.
6. Overall ground maintenance treatment: such as stone with large porosity (sandstone, cave stone, etc. ) It needs to be coated with marble protectant. After 12 hours, use a washing machine to grind chemicals K2 and K3 alternately on the ground, that is, K2-K3-K2-K3-K2 * * five times, then put on a white polishing pad and spray a small amount of k 65438+.
7. Ground cleaning and maintenance: When a crystal mirror is formed on the stone surface, use a vacuum cleaner to absorb the residue and moisture on the ground, and finally use a polishing pad to polish it, so that the whole ground is completely dry and bright as a mirror. If it is damaged locally, it can be repaired locally, and you can walk on it at any time after the construction is completed.
I think these methods are all methods of stone renovation. At that time, the maintenance of stone depended on doing different daily cleaning work for it every day, and keeping the surface of stone clean by regular dust removal. Please don't polish with a black waxing pad. Remember to clean up the tools after each work so that you can use them next time. Special attention should be paid to cleaning pads and stainless steel silk cotton pads, which need to be kept clean frequently to ensure normal performance.
