5 Common Mistakes with Quartz Composite
5 Common Mistakes with Quartz Composite
Engineered quartz is marketed as "maintenance-free", which leads to complacency. These mistakes void warranties and cause damage that's expensive to repair.
Mistake #1
Placing hot cookware directly on the surface
Why this is a problem
Quartz composite contains resin binders that soften at high temperatures. A hot pan can create a permanent white mark or burn spot. Unlike natural stone, this cannot be polished out.
How to fix it
Minor discolouration might improve with Lithofin MN Power-Clean. Severe burns require professional slab replacement.
Prevention
Always use trivets and heat pads. Even brief contact with a hot pan can damage the resin.
Mistake #2
Using bleach or hydrogen peroxide regularly
Why this is a problem
Occasional use is fine, but regular bleach exposure breaks down the resin binder over time, causing the surface to become rough and dull in the cleaned area.
How to fix it
Roughened areas cannot be restored to factory finish. A matte polish may improve uniformity.
Prevention
Use pH-neutral Lithofin KF Wash & Clean for daily cleaning. Reserve stronger cleaners for occasional stain removal only.
Mistake #3
Cleaning with harsh alkaline oven cleaners
Why this is a problem
Oven cleaners (caustic soda) attack the resin binder. The surface becomes rough and matte. Some colours may also shift permanently.
How to fix it
The damage is irreversible. Professional refinishing may help, but factory gloss cannot be restored.
Prevention
Only use products rated for engineered stone. Lithofin KF Wash & Clean or MN Wash & Clean are both safe.
Mistake #4
Using the countertop as a cutting board
Why this is a problem
Quartz is hard (Mohs 7), but knife edges concentrate enormous pressure on small points. Over time, cutting creates visible scratch marks, especially on dark colours.
How to fix it
Light scratches can be buffed with a fine abrasive pad. Deep scratches need professional attention.
Prevention
Always use a cutting board. It takes two seconds and prevents years of cumulative damage.
Mistake #5
Installing quartz composite outdoors
Why this is a problem
UV light degrades the resin binder. Outdoor quartz fades, yellows, and eventually becomes brittle. Most manufacturers explicitly exclude outdoor use from their warranty.
How to fix it
No fix for UV degradation. The slab must be replaced.
Prevention
Use quartz composite indoors only. For outdoor countertops, choose granite or natural stone.
