Corian® panels are branded on the underside and edge with a serial number and DuPont™ logo. After the material has been worked, it can be difficult to find these markings, though every original product is accompanied by documentation demonstrating its authenticity.

Yes, so long as the installation surface is perfectly level. If this is not the case, it must be levelled using an appropriate product.

This is generally done by the plumbing contractor installing the other elements in a bathroom. Planit offers plumbing contractors and installers a free technical information service.

Yes. The cracks around the opening in the countertop near the hob are caused by excessive heat (we do not recommend gas hobs) or the excessive dimensions of pots (in the case of induction hobs).
While not covered by our warranty, these damages are easy to repair. Repairs are made in situ: our technicians will use a router to remove the damaged parts and then glue on a new piece of the same material, removing any excess glue with a sander.
If you are located in the provinces of Bolzano, Trento or Verona, please send us an email at info@planit.it, including a photograph showing any damage. Please place a ruler in the photograph to help us understand the scale of the damage. We will prepare a cost estimate for repairs. If you are located outside these 3 Italian provinces, please contact the company that supplied you kitchen countertop, or one of the many specialised Corian®

For cleaning kitchen sinks we recommend using an abrasive Scotch-Brite sponge and a limescale remover such as Viakal (or simple white wine vinegar) to remove calcium build-up on the sink bottom. When a Corian® sink shows signs of staining it is not the material that is stained, but the encrustation of limescale that is stained by different foods (tea, coffee, carrots, wine, etc.). This is easy to verify: if you apply bleach diluted with water you will see the bottom of the sink turn white in only a few minutes; this means that the limescale has been bleached of the substance that had stained it. The problem is best resolved at the root cause by dissolving the limescale to eliminate any stains. Be careful: an abrasive sponge can ruin the chrome parts of taps and faucets or the drain cover so we suggest working far from the taps and removing the drain cover.

It can happen that a kitchen sink or countertop can be damaged by a particularly violent impact, or that chips or cracks appear in the surface or a burn mark when a hot pot is inadvertently left on the counter.

Corian® can be purchased from kitchen retailers or cabinet makers, if the order includes the kitchen, or directly from a fabricator when all you need to do is substitute the countertop. For the bathroom, retailers of bathroom fixtures are the ideal reference for purchasing a washbasin, shower tray or bathtub. Reception desks and cladding for bar counters can be purchased directly from a Corian® fabricator or from the cabinet maker providing the rest of the furnishings.

Yes. The Corian® colour palette also contains dark colours, though not all are recommended for countertops or surfaces subject to intense wear because they are sensitive to dragging and tend to scratch easily. Solid dark colours or marble- or stone-effect textures are instead useful as surfaces and cladding.

Quartz is a mineral material in coloured granules held together by acrylic or polyester resins. It is rigid, heavy, impossible to repair or restore. Joints are always visible.
Corian®, instead, is a compact material, held together by acrylic resins. It is simultaneously flexible and rigid, allows for invisible joints and can be repaired if damaged. The number of possible joints is almost infinite.

Marble and granite kitchen countertops are subjected to an anti-stain treatment to protect them against the penetration of liquids. Kneading on a marble or granite surface is not hygienic because the natural micro-cracks in these surfaces can hold bacteria and microbes that may contaminate food. Corian®, on the other hand, is non-porous and thus unsuitable to the proliferation of bacteria. What is more it is not stained by common substances found in the kitchen. Additionally, it is certified as a material suitable for direct contact with food products.

Corian® is a unique solid surface. As hard as stone and as malleable as wood, it technically surpasses both materials for its thermoformability and invisible joints. Strong and durable, it easily resists against impacts, scratches and day-to-day wear. Colours and textures are present across the entire thickness of this material which means they do not suffer from wear. Corian® is considered one of the few materials that can be repaired, making it a wining choice with respect to others that can be irremediably damaged. Small scratches can be removed using an abrasive Scotch-Brite sponge, while more consistent damages, caused by improper use, can be invisibly repaired by inserting a new piece of the same material. Inert, non-toxic, chemically non-reactive, Corian® is certified for contact with food products. It releases no volatile substances into the environment which has earned it GreenGuard® certification.

Mineralmarble is a material composed of 75% natural minerals and 25% polyester resin, finished with a technical layer of marine gelcoat. The gelcoat finish is often white, though it can also be coloured. During daily cleaning it is not possible to use abrasive or aggressive detergents, as they will ruin the surface. The gelcoat is only 1 millimetre thick so if it becomes damaged the material below will begin to absorb any substance resting on the surface.

It is possible to thermoform Corian® in Glacier White, creating a fold with a minimum radius of 50 mm, using a mould and a counter mould. While dark colours of Corian® can be thermoformed, this creates a light area along the fold line whose appearance needs to be considered in relation to the desired result. Textured surfaces, such as coarse grain dots, instead, are damaged during the heating phase; before undertaking a project that involves thermoforming, we suggest getting in touch with us to discuss the details.

Corian® is produced with an opaque finish and provided with this finish to fabricators belonging to the Corian® Quality Network. After cutting and shaping it to create a workable surface, they supply it for installation with the same finish. This opaque finish is thus the natural finish of Corian®.
Those who prefer a polished finish can use a soft cloth instead of an abrasive Scotch-Brite sponge, though it should be noted that correct maintenance will tend to return Corian® to its natural opacity.
While not practical for counter tops, for design elements not subject to intense wear, surfaces in Corian® can be polished until they shine like the body of a brand new car.

Owing to the processes involved in their fabrication, wash basins and bathtubs can only be painted externally; for the same reason, only the panels of vanity cabinets and not the top are painted.

No. It is a non-toxic material that creates no problems with dust or harmful emissions. Even when it is worked, vacuum systems attached to equipment minimise concentrations of dust.

Does Corian® suffer from ‘yellowing’?

No. Corian® is composed for one third of transparent acrylic resin (poly(methyl methacrylate) PMMA) and two thirds natural minerals. The principal among these latter is alumina trihydrate (ATH), a white powder derived from bauxite, the mineral from which aluminium is extracted. It is a mineral material in powder form held together by an acrylic resin.
