Analysis of the Whole Process of Stone Care: From Basic Cleaning to Professional Renovation


1. Finished product protection




In order to prevent various pollution caused by construction and damage to various finished products on the construction site, or to facilitate construction site cleaning, some effective measures have been taken: for example, transparent silicone can be used to draw a thin line at the joint between the solid wood surface and the ground stone, which can prevent water from entering the wood, causing the wood to swell, turn black, etc. (It is absolutely prohibited to use strong adhesive tape on the solid wood surface, wallpaper, and wallpaper, and can only use textured paper)




2. Inspect the paved stone floor




Including: maintenance period inspection of ground stone, flatness inspection, inspection for hollowing, inspection for visible and hidden cracks, inspection for missing edges and corners, inspection for protective effects, etc. Because:




Insufficient maintenance period can lead to stone hollowing phenomenon;




Poor flatness can lead to poor flatness of the overall stone ground after polishing, which may cause water waves and hollowing of the ground, resulting in the occurrence of stone cracking during grinding and future use.




Bright and dark cracks can cause obvious cracks in stone after grinding and polishing.




Missing edges and corners can cause the texture to be difficult to coordinate with large areas of stone even after grinding and polishing, which affects the overall effect.




Poor protective effect can lead to water spots, oxidation, and other phenomena in stone grinding.




3. Filing with Party A




Report the above inspection results to Party A for filing to avoid unclear responsibilities in the future.




4. Tailor processing




The purpose is to solve the problem of stone edge pollution on both sides of stone gaps and avoid the problem of black edges in stone gaps; It can also solve the problem of uneven gaps caused by stone processing dimensions or paving.




Standard: The seam should be straight, the seam opening should be fine, and the stone surface should not be broken. The thickness of the cutting piece is standard at 0.2.




5. Local polishing and leveling:




For areas with particularly high cutting edges, first use a metal steel bowl to slightly flatten them (it is necessary to grind the other side higher and wider as much as possible to avoid the grinding disc falling off due to high cutting edges during subsequent processes using large machines for polishing)




6. Cleaning treatment:




Clean the seam with a vacuum cleaner or brush, and if necessary, use a blade to scrape the seam clean to ensure that there are no black edges after polishing.




7. Anti fouling treatment of seam opening:




Apply different anti fouling agents according to the quality of the stone (jade and light colored stones are essential, otherwise black shadows will appear after the crystal surface is completed) to prevent the glue from seeping into the stone before it dries and solidifies.




8. Seamless processing:




Also known as caulking or patching. This process must be filled with fullness: using bulging as the standard. Otherwise, the colloid will shrink after solidification and appear as half cracks after polishing.




9. Initial grinding treatment (No. 30-50):




Use a 12 head professional stone leveling machine to smooth out the cutting edges, unevenness, and scratches caused by deformation, paving, processing, and other factors in the stone during construction. Clean up the hole contamination through initial grinding, creating conditions for subsequent hole repair, fine grinding, and other processes.




10. Clean stone surface:




Use a professional mechanical tool with a stone pore cleaning brush (steel wire brush) to clean the dirt at the damaged or broken parts of the stone, ensuring that the repair adhesive fully adheres to the stone in the subsequent process.




This part is quite important: if not cleaned with a steel wire brush, the dirt on the damaged area of the stone cannot be cleaned completely, which naturally affects the adhesion between the repair adhesive and the stone, causing the skin to peel off and thereby reducing the quality of the repair.




11. Hole, burst edge, and damage repair treatment (which is crucial and exquisite for the process of stone mosaic).




After the initial grinding is completed, wash the stone surface and check the stone surface after it dries. If the holes are large but few, a solid repair adhesive with similar color can be prepared for repair; If there are many small holes, liquid repair glue must be used for batch repair; If there is a linear damage, the color of the stone texture must be determined first, and then a glue that is close to the texture and color of the stone should be used for repair.




Please note:


1. If liquid repair glue is used, the ratio of catalyst and curing agent must be appropriate, otherwise the glue will not dry or burn for a long time.




2. If liquid glue is used, it must be polished every other day.




3. If UV curing repair is used, UV protection measures must be taken.



12. Medium grinding treatment (No. 150)


Remove excess repair glue from the stone surface during the initial grinding marks and hole repair process, further adjust the flatness of the grinding surface, and prepare for the lower polishing process.


Standard: No scratch of size 50! No residual repair glue!


13. Repair and handle again


Any omissions, glue loss, and other issues in the upper process will be repaired again in this process.


14. Edge grinding treatment (referred to as trimming):


For edges and corners that cannot be completed by large machines or edge scratches left by primary grinding and intermediate grinding, use special equipment for edges and corners (use 50-150-300-500 supporting role grinder for water grinding discs) to grind, polish and connect edges and corners.


Standard: No cuts at the corners! There are no burrs or scratches on the edges!


15. Fine grinding treatment (300-500-1000-3000-6000):


On the basis that the flatness of the ground stone in the initial and intermediate grinding has basically reached the standard, this process mainly grinds and processes the glossiness of the stone to prepare for the next polishing process.


Key points of the process: Starting from No. 500, the grinding disc must be placed on the edge! Perform edge pressing! First, polish the edges around and then polish the middle. The intermediate grinding method is the same as the intermediate grinding method, and attention must be paid to the edge pressing: if using a 220 machine for grinding, the machine must be moved from front to back and the working plate of the machine should be tightly pressed against the wall. If using a 380 machine, it is necessary to approach the wall by the corner of the machine.


16. Stone disease resistance treatment:


After the above process is completed and the stone is completely dried (at room temperature, at least 48 hours), use a brush to apply a solvent based, oil-based protective agent with alkali inhibiting factor evenly to the stone surface. And let it stand for 24 hours.


17. Polishing and crystallization treatment


After the anti alkali agent is completely absorbed by the stone, use a 220 machine to polish and crystallize the stone surface with polishing discs and imported maintenance crystallization agent. Wash the stone surface and let it stand for 24 hours.


18. Stone crystal treatment


First, sprinkle sufficient stone brightener on the surface of the stone, and then use a white sheet with a professional machine to polish back and forth until the medicine is basically dry.


19. Clearing treatment


Clean up the hygiene around the edges and corners, and clean a large area in the middle with dust and electrostatic water.


Quality standards:


The stone surface is clean and tidy; Smooth and without obvious water waves (the difference in curvature of the benchmark projection shall not exceed 15 degrees); The seam connection is natural and perfect, with no obvious color difference, no half seam, broken seam, or black seam; The edges are bright, without burrs or obvious joints. The overall stone surface feels delicate, oily, shiny, transparent, and has a tested brightness of over 95 degrees. Has anti slip effect.
