The appearance of a worktop can be totally transformed by dressing it with zinc. The operation requires few tools, but a perfect implementation for a guaranteed result.

Ubiquitous in professional kitchens, stainless steel is distinguished by its extreme resistance to mechanical and thermal shock as well as its great simplicity of maintenance. But it is a rather expensive material and difficult to work because of its rigidity. For example, a perfectly straight 90° fold over a great length is impossible to obtain without a folder. As for cutting with shears, they are reserved for fairly thin sheets and small lengths. Otherwise, the operation turns to the test of strength! Such constraints do not exist with more malleable metals such as aluminum or zinc.

A material to do everything

In addition to eavestroughs and eavestroughs, zinc is usually used to connect (flashing) chimney stacks and roof windows. It also gives birth to the classic "long leaf" covers of Parisian buildings. Available in both DIY shops and supermarkets, the thickness used here (0.65 mm) is ideal for this application.

Zinc in the kitchen: economical and easy going

Another advantage is that zinc is also much cheaper than stainless steel and aluminum. And even if it is a little cold brittle, this is not a problem in a heated volume. He is willing to be shaped by hand or with a mallet (wood or rubber), directly on the tray to be dressed, which must be previously separated from the furniture he overcomes. Like exposed aluminum with no moisture treatment, zinc spontaneously protects itself with superficial oxidation that tarnishes its original shiny appearance. But it is still easy to maintain with ordinary detergents.

1 Cutting and shaping the plate

1 Cutting and shaping the plate

Locate the cut line on the zinc plate (ruler and scriber or cutter). Cut it with a sheet metal shear: lift one of the edges as the tool progresses.

Make sure that the zinc plate protrudes around the worktop 9 to 10 cm in order to dress its 38 mm edge and create a small flap on the underside.

Bridle the zinc sheet with clamps. Plate it against a ridge by helping you with one hand. With a mallet, mark the angle. Then fold the zinc sheet with your hand, then flatten it carefully with the mallet (wearing gloves is recommended because the zinc is sharp).

At each corner of the worktop, cut the zinc sheet with the shear. This cut allows to fold cleanly zinc.

Then finalize all the edges using the mallet.

Near the edges, the sheet tends to rise a little: replace it along the sides with a rubber mallet.

Turn the tray over to flatten the edges of the sheet one after the other on the underside of the panel: hold the zinc with one hand and hit the other. Block the flap with a point.

To complete the flap, a return of 2 cm of sheet is enough: cut off the surplus with the shears after marking the cuts...

At the corners, cut the zinc at 45°, making sure to stop before singing. Otherwise the end of the notch may be seen.

Spread a little the first flap to access the second. Cut it in turn at 45°.

Then flatten very carefully the sheets (flaps and songs) so that the angle of the future worktop is perfect.

Return the set to judge the result. Adjust if necessary with small strokes of mallet... and install the new work plan on the low boxes concerned.

To process a hob, first make a covering identical to that of the worktop. Then turn the unit over and mark the location of the hob.

Remove the cover by dragging it without deforming it. Drill a hole in one of the corners to facilitate cutting. Then cut with the shears.

The cutting is done without difficulty provided to raise the fall as and when. Also, be careful not to cut beyond the angles, as this may compromise the result.

Then put the cover back on the panel. Check that the edges of the two cuts coincide perfectly. Screw the zinc underneath the worktop.

The hob is returned to its original location. The brackets are then screwed after removing the furniture drawer.

The installation ends with the connection of the appliance, provided here under the cabinet (make sure that the main power supply is switched off).

The plan surrounding the sink must also be dressed with zinc. Given its size, two sheets of zinc are needed. Their connection is realized where it will be seen the least...

... that is to say along one side of the sink. Make sure that the edges of the zinc sheets are not damaged, otherwise they will not connect properly.

A more rigid alternative...

A more rigid alternative...

The dressing of a worktop often results in the removal of the original tray to cover the songs and its underside. If you wish to avoid this operation, use a stiffer material than zinc. This is for example the case of aluminum, available in plates of 200 x 100 cm and in varying thicknesses. On the other hand, aluminum is three times more expensive than zinc! Side implementation, the aluminum sheet can be cut with a guided circular saw. It can also be glued to neoprene glue, just like a veneer.
