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); the polished surface is hard, but not invulnerable.
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 %. A sealer would tend to show up on the surface as a haze.
Kitchen. 3141 Osprey 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. The dishwasher must not be built in directly against the underside of the slab with full contact – heat protection is standard practice. On the speckled beige slab, dark stains (red wine, coffee, berry juice) and grease marks are less conspicuous than on a solid white slab; even so, the material is no invitation to let them stand.
Bathroom. In the bathroom, Osprey can be used 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. On the warm creamy slab, limescale rings are less visible as lighter shadows than on pure white grades, but they do show up in direct raking light.
Floors and stairs. The surface finishes available from stock are listed in the »Finishes« block further down. Dirt-trapping mats at the entrance reduce the ingress of abrasive particles.
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.
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. The surface finishes available from stock are listed in the »Finishes« block further down.
