1.Common problems in the processing stage

1. Cutting broken edges and cracking

The rock slab has high hardness but relatively obvious brittleness. If ordinary ceramic tile cutting equipment and cutting tools are not sharp enough, or the cutting speed is too fast, it is easy to cause edge collapse and surface cracking.
Solution: A specialized waterjet or CNC cutting machine for rock slabs needs to be used. Before cutting, a protective film should be applied to the slab surface to control the cutting speed.

2. Hole fracture

When opening holes on kitchen countertops and bathroom basins, if the opening position is too close to the edge of the board or the impact force of the opening tool is too strong, it is easy to cause the rock board to break.
Solution: Before drilling, reinforcement treatment should be carried out around the hole position, using a diamond drill and low-speed, water cooling operation.

1. Wall tiling with hollowing and peeling

Rock slabs, especially large-sized ones, have a large weight. If the base treatment is not smooth, the tile adhesive is not evenly applied, or if the backing adhesive/dry hanging process is not used, it is easy to have hollowing or even peeling.
Solution: The wall base needs to be leveled and reinforced, using specialized tile adhesive for rock slabs. For large-sized rock slabs, it is recommended to use dry hanging or thin pasting methods.

2. The ground is covered with raised tiles

Ground base settlement, stepping on tile adhesive before fully curing, or insufficient reserved expansion joints can cause the rock slab to rise.
Solution: The ground base should be well moisture-proof and reinforced. After laying, it should be left to stand for 24-48 hours before use, and expansion joints should be reserved according to specifications.

1. Surface bleeding and residual stains

Although rock slabs have strong anti fouling properties, long-term exposure to strong dyes such as soy sauce, vinegar, and red wine, and failure to clean them in a timely manner, may penetrate into the texture gaps and leave stains.
Solution: Stains should be wiped with neutral cleaning agents in a timely manner, avoiding the use of strong acid and alkali cleaning agents.
Surface scratches (special circumstances)
The Mohs hardness of the rock slab is as high as 6-7 levels, and there will be no marks left by daily cutting tools. However, if high hardness metals (such as tungsten steel) or sandpaper are used for strong friction, fine scratches may still occur.
Solution: Avoid using sharp and hard objects to scrape vigorously. If there are minor scratches, use a specialized repair agent for rock slabs.

2. Cracking caused by thermal shock

In rare cases, high-temperature objects (such as hot pots) that come into direct contact with rock slabs for extended periods of time, or rock slabs that experience sudden alternation of heat and cold (such as rock slabs that have just been poured with cold water being immediately placed in high-temperature pots), may cause internal stress cracking.
Solution: It is recommended to place a pot pad on the hot pot to avoid sudden temperature fluctuations on the surface of the rock slab.

1. Confusion between genuine and fake rock slabs

Some merchants will use high hardness ceramic tiles to impersonate rock slabs, and the temperature resistance and impact resistance of these imitations are far inferior to real rock slabs.
Identification: The back of the genuine rock slab will have a brand logo and the words’ carved stone ‘, and the merchant can be requested to provide a testing report.

2. The distinction between the overall texture and the surface texture of the rock slab is unclear

Non solid rock slabs only have texture on the surface, and after cutting or chamfering, the edges will expose the base color of the slab, affecting its appearance.
Identification: Check the cross-section of the rock slab, and the texture of the entire rock slab cross-section is consistent with the surface.
