Is Corian truly “solid”?
Corian worktops are made from reconstituted pulverised natural minerals, strengthened by polymer acrylic resins in a ratio of about 1/3 resin to 2/3 mineral compound. This translates to a solid surface with all colours and patterns going throughout the entire thickness of the worktop. This means Corian is a solid, hard, non-porous homogenous slab, suitable for elegant worktops in kitchens or bathrooms, vanity tops, countertops, benches, or shower walls. Corian can be engraved, or polished or textured to personalise it and through a special process can be shaped into basins, sinks, shower trays, etc. It can even be formed, sculpted and shaped into almost any other shape – limited only by your imagination.The good news is also that any scratches or damage can be sanded or polished out, without changing the beauty or appearance of the surface. Cavities can be filled. The quality of Corian worktops is backed by two levels of protection, a 10 year warranty against product defects and also a 10 year limited “installed” warranty.
In which thickness is Corian available?
For various applications and cost considerations, Corian is manufactured in sheets of 6 mm, 12.3 mm and 19 mm.
6 mm sheets are usually limited to vertical applications (for instance wall cladding.) The choice between 12.3 mm and 19 mm sheets is usually determined by personal choice, aesthetic appearance, cost, strength required over longer surfaces, and durability in high traffic or robust areas.
Various techniques are employed to support and strengthen worktops, countertops or vertical applications stretching over long spans, and undermounting sinks and basins, without detracting from the classiness of Corian.
Is Corian only available as sheets?
Because Corian can be formed and shaped, it is moulded into integrated single or double basins, sinks, accessories, end details, upstands, downturns, splashbacks, fixtures, fittings, decorations, etc. almost perfectly matching the colour and patterns of your worktops. Sheets can also be moulded, shaped or sculpted into various artistic shapes in the factory.
How many different colours are available for Corian worktops?
The Corian colour range is constantly adapted to give better choices and versatility and the current 80 colours, in combination with other materials, allow for an almost unlimited working palette.
The designer can choose from single colours or a neutral basis, to eye catching bright colours and harmonies or contrasts, to the classic look of natural stone.
Sub palettes are divided into Extra lights, Beiges, Naturals, Warms, Yellow greens, Greens, Blues, Brights, Greys and Extra darks. For easy reference, Worktops.net have also divided the colours into price bands.
Because Corian is essentially made from natural minerals, slight variations of colour and pattern will be discerned from one sheet to the next. Rather than detract from the beauty of the worktops, this adds that additional natural aesthetic appeal.
How are Corian worktops joined to create harmony and a seamless appearance?
To minimise wastage and for maximum strength, corner joints and butt end joints are usually square rather than mitred. They are smoothed and joined with specially formulated colour coordinated adhesives, caulking and a heat process that make joints almost imperceptible, giving the appearance of a solid, seamless design.
Cut-outs and corners are rounded and polished smooth and edges and to finish the worktops off, end details, up-stands and downturns are available in a wide variety of shapes and designs.
Provision is made for clearances to allow for thermal expansion and contraction. This avoids cracks showing later.

When should I not use Corian?
In the first instance, one should not use Corian when common sense tells you it is not safe. For instance, if it might be too heavy to be properly supported, if moisture could be trapped behind it and damage the structure behind, above or below it, or when it will be exposed to strong corrosive chemicals or acids.
Typical examples would be when the wall or masonry construction is not strong enough to support its weight. Corian is not recommended for photographic laboratories, as corrosive chemicals and developing liquid stains will require sanding to remove, which in turn creates dust in the laboratory.
Corian can withstand high temperatures, but in extreme conditions, heat shields or hot pads should be used to protect it.
Corian is non-porous and resistant to stains, so chemicals will not be absorbed, but corrosive chemicals or acids will damage the surface. Of course, the duration of contact will determine the extent of damage.
6 mm sheets are not recommended for horizontal application, worktops, countertops, etc.
When harder worker surfaces are required, it might be advisable to consider quartz worktops.
