Cleaning. Day to day, warm water, a soft cloth or a clean mop and a neutral to mildly alkaline pH cleaner are enough. Soapy engineered-stone cleaners, mild all-purpose cleaners, mild washing-up foam and special engineered quartz care products are suitable. Caesarstone recommends its own care products (Caesarstone Cleaner) – these are not essential, but well matched. Wipe up spilled liquids – wine, coffee, juices, oil – promptly in everyday use.
Do not use. Concentrated acids (sulphuric, hydrochloric, nitric acid), cement and rust removers, paint strippers, oven cleaners, acetone, petrol, thinners, nitro cleaners and very strongly alkaline industrial cleaners are off limits – they can attack the polyester resin. Also avoid chlorine-based bleaches in high concentration. Do without abrasive pads (steel wool, green scouring pads); scratching is particularly undesirable on the honed C400 surface.
Impregnation. A classic natural stone impregnation is not required – engineered quartz is dense and free of pores in itself, water absorption is below 0.05 %.
C400 surface. The finely honed C400 texture reacts somewhat more sensitively to films of grease and visible wipe streaks than a polished version; isolated water droplets dry off less smoothly. We recommend prompt drying off with a soft microfibre cloth and, from time to time, a special engineered-stone cleaner for matt engineered quartz surfaces.
Kitchen. 4001 Fresh Concrete ICON is a classic kitchen material. Despite its high material hardness and acid resistance the rule is: use chopping boards (knife marks can gradually leave the polyester resin dull), use trivets for hot pots and pans – direct point heat can cause local discolouration. On direct contact with a hot baking tray (above roughly 150 °C) there is a risk of stress cracks. On the pale creamy white slab, dark stains (red wine, coffee, berry juice) are clearly visible, but if dealt with promptly they can usually be removed without a trace.
Bathroom. In the bathroom, Fresh Concrete can be used very well as a vanity top, wall cladding, bath surround and shower. Do not use anti-limescale sprays and limescale-dissolving sanitary cleaners in high concentration; in the shower area wipe standing water away promptly so that no limescale film builds up.
Outdoors and frost. Not suitable for exterior construction. The polyester binder yellows under UV radiation, and freeze-thaw cycles can cause micro defects. Nor is it to be recommended permanently in fully sunlit conservatories or open loggias – Caesarstone explicitly excludes exterior use and fully sunlit interior surfaces from the warranty.
Guarantee and repair. In residential use Caesarstone grants a lifetime warranty on material and fabrication defects (“Caesarstone Forever”), on condition of fabrication and care to standard by certified specialist firms.
