What are the process flows for stone polishing?

1、 Construction technology for ground stone maintenance

1. Cleaning the venue:

Thoroughly clean the working surface with a dust pusher and vacuum cleaner.

2. 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. This 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.

3. Local polishing and leveling:

For areas with particularly high cutting edges, first use a metal steel bowl to slightly flatten them.

4. 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.

5. Anti-fouling treatment of seam opening:

Apply different anti-fouling agents according to the quality of the stone to prevent the glue from seeping into the stone before it dries and solidifies.

6. 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.

7. Initial grinding treatment:

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.

8. Clean stone surface:

Use professional machinery and a stone pore cleaning 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.

9. Repair and repair of holes, edges, and damages.

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 a 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 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.

10. Medium grinding treatment:

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. This standard: No scratch of size 50! No residual repair glue!

11. Repair and handle again.

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

12. Edge grinding treatment:

For edge and corner parts that cannot be completed by large machines, or edge scratches left by initial and intermediate grinding, use specialized edge and corner equipment for edge and corner grinding, polishing, and connection treatment. This standard: There are no cuts at the corners! There are no burrs or scratches on the edges.

13. Fine grinding treatment:

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

14. Stone disease resistance treatment:

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

15. 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 an imported maintenance crystallization agent. Wash the stone surface and let it stand for 24 hours.

16. 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 it back and forth until the medicine is dry.

17. Clearing the site.

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

2、 Construction technology for wall stone maintenance

1. Cleaning treatment:

Use a brush to clean the seam, and if necessary, use a blade to scrape the seam clean. For areas where the installation worker has corrected significant color deviation, use a cutting blade to open the seam. Ensure that the crystal surface of the adhesive has no black edges or color bands.

2. 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.

3. Glial clearance:

When the sealant is about to dry, use a brand new art blade to immediately remove the excess colloid, to prevent the sealant from producing high heat and burning the stone surface during the drying process. And thoroughly remove the residual colloid on the stone surface with a glue remover.

4. Hole, edge burst, and damage repair treatment:

If the holes are large but few, a solid repair adhesive with a similar color can be prepared for repair; If there is 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.

5. Local polishing and leveling:

Professional polishing and leveling of cuts exceeding 1mm at the joint to a bright (dry grinding) finish.

6. Grinding marks and polishing treatment:

For areas that have been forced to be polished by the installer due to uneven installation or broken columns during installation, they should be restored and polished to a smooth and bright surface.

7. Clean stone surface:

Use professional equipment and chemicals to remove any remaining paint and other dirt from the stone surface decoration.

8. Polishing and crystallization treatment.

Use a hand polishing machine and professional maintenance crystallizer to polish and crystallize the stone surface.

9. Clearing treatment:

Use professional tools to remove any crystal residue splashed during the polishing and crystallization process.
