Sintered Stone vs Quartz
| Parameter | Sintered stone | Quartz |
|---|---|---|
| Tahan panas | 1.200 C | Terbatas, resin bisa menguning |
| Kekerasan | Mohs 6-7 | Mohs 7 |
| Penyerapan air | Di bawah 0,2 persen | Sangat rendah |
| Paparan luar ruang | Tahan UV | Tidak disarankan untuk luar ruang |
| Ketebalan tersedia | 6 / 9 / 12 / 15 / 20 mm | Umumnya 20 / 30 mm |
Sintered stone values come from the manufacturer specification. Values for the compared material are general and vary by product.
Both are engineered surfaces, which is why they get confused. The difference is the binder: quartz uses resin, sintered stone is fired.
The short answer
Quartz is a strong, consistent surface with excellent pattern control and a familiar price point. Sintered stone tolerates more heat, absorbs less water and is UV stable on selected surfaces, which matters near windows and outdoors. For a standard kitchen with no unusual exposure, both work; the choice usually comes down to heat, sun and design intent.
| Property | Sintered stone | Quartz |
|---|---|---|
| Binder | Fired: no resin | Resin-bound: roughly 90% quartz plus resin |
| Heat | Rated to 1,200°C | Sensitive above roughly 150°C; hot pans can mark |
| UV | UV stable on selected surfaces | Can yellow with prolonged sun exposure |
| Water absorption | Under 0.2% | Very low, but resin can be affected by solvents |
| Pattern control | Repeatable; bookmatch possible | Very uniform; excellent colour consistency |
| Outdoor use | Selected surfaces | Not recommended |
| Repair | Fabricator repair; pattern cannot be perfectly matched | Repairable by a specialist, seams visible |
| Best for | Kitchens with heavy heat, sunny rooms, outdoor-adjacent spaces | Uniform colour schemes, budget-controlled projects |
Where quartz is the sensible choice
When colour consistency matters more than veining, when the budget is fixed, and when the surface will not sit in direct sun or take pans straight off the hob. A well-specified quartz counter is a good counter.
Where sintered stone is worth the difference
Kitchens with heavy cooking, apartments with floor-to-ceiling glass, and any project needing the same surface indoors and out. The absence of resin is what makes the difference in heat and UV.
Frequently Asked Questions
Short answers for homeowners and project teams in Indonesia.
Can quartz go outdoors?
Generally no. Resin can yellow and degrade with UV exposure.
Is sintered stone more heat resistant than quartz?
Yes. Sintered stone is fired and rated to 1,200°C; quartz is resin-bound and sensitive to hot pans.
Which looks more like natural stone?
Sintered stone, because veining can be printed at high definition and matched across slabs.
Is quartz cheaper?
Often, at slab level. Compare with the same edge detail, cut-outs and delivery scope.
