What's an upstand?

Upstand, 100mm highWorktop 100mm high 22mm thick Silicone bead 600mm deep worktop Wall

What it is

A 100mm-high strip in Nero Portoro, the same decor as your worktop. It sits along the back edge of the worktop, against the wall.

Why you need one

Walls are rarely straight, so there's nearly always a gap between worktop and wall. An upstand covers it, stops water and crumbs getting down the back, and gives a neat finished line. It's the simplest, cheapest way to finish a worktop.

Sizes

    Most kitchens need one length per wall run.

    Fitting

    Cut it to length with a fine-tooth saw and bond it to the wall with grab adhesive. Run a bead of clear or matching silicone along the bottom edge, and finish any exposed ends with an end cap.

    Upstand or splashback?

    Choose an upstand if you're tiling above the worktop, or want the cheapest neat finish. Choose a splashback behind the hob or sink, or if you want no tiles at all. Lots of kitchens use both.

    Read the full fitting guide

    What's a splashback?

    Splashbackupstand heightHob and oven 640mm high 10mm thick Worktop Wall

    What it is

    A full-height panel in Nero Portoro, the same decor as your worktop, fixed to the wall behind the hob or sink.

    Why choose one

    One continuous wipe-clean surface with no grout lines, so there's nothing to stain or scrub between tiles. It protects the wall from splashes and cooking grease, and makes the worktop and wall look like one piece.

    Sizes

      Behind a hob

      Check the minimum clearance to a laminate panel in your hob's installation manual. Gas hobs usually need more space, or a heat-resistant panel behind the burners.

      Fitting

      Cut it to size and bond it to a flat, sound wall with panel adhesive. Seal the bottom edge to the worktop with silicone.

      Upstand or splashback?

      Choose an upstand if you're tiling above the worktop, or want the cheapest neat finish. Choose a splashback behind the hob or sink, or if you want no tiles at all. Lots of kitchens use both.

      What's an edging strip?

      BeforeCut end: barechipboard core AfterEdging strip,45mm wide, coversa cut end

      What it is

      A strip in Nero Portoro that covers the cut end of the worktop. It comes pre-glued, or is fixed with contact adhesive.

      When you need it

      Whenever a cut end is on show: at the end of a run, on a breakfast bar, or anywhere you've cut a length down.

      Sizes

        Fitting

        1. Glue Spread contact adhesive on the end and the strip, or warm a pre-glued strip.
        2. Press Press it on firmly from the middle outwards, with a block of wood.
        3. Trim and file Trim the overhang with a sharp blade, then file the edges down at a slight angle.

        What are joining strips?

        Corner strip (L-shape)Straight stripSeen from above Aluminium strip38mm worktop: use the38mm stripWorktopWorktop

        What it is

        An aluminium strip that joins two worktop lengths without a router or jig. The web slips between the two ends and the cap covers the joint.

        Straight or corner

        Straight: joins two lengths in a line. Corner: makes an L-shaped join where two runs meet.

        Sizes

          Match the strip to your worktop's thickness: a 38mm strip for a 38mm worktop.

          The alternative

          A mason's mitre gives a seamless corner, but it needs a worktop jig and a router. See both options in our fitting guide.

          What are end caps?

          BeforeAfterExposed endEnd capScrewed over therounded profile Left end capRight end capYou, facing the worktopWall

          What it is

          An aluminium cap that finishes the exposed end of a postformed worktop, following its rounded front edge.

          Left or right?

          Stand facing the worktop. If the exposed end is on your left, you need a left end cap; if it's on your right, a right end cap.

          Sizes

            Match the cap to your worktop's thickness.

            Fitting

            Hold the cap against the end, drill small pilot holes and screw it on. A thin bead of silicone behind it keeps water out of the end.

            Read the full fitting guide

            What's in the joint kit?

            3 connector boltsJoint sealant Seen from underneathBolts pull the joint tight;sealant keeps water out

            What's in it

            Three connector bolts and a tube of joint sealant: everything to hold one worktop joint together.

            What it's for

            The bolts sit in pockets cut underneath both worktops and pull the joint tight. The sealant goes on the joint faces first, so water can't get into the core.

            How many?

            One kit per worktop joint.

              Care and cleaning

              Wipe with warm water and a little washing-up liquid, then dry. For limescale around the tap, use a diluted vinegar solution and rinse. Avoid abrasive pads and bleach-based sprays left to sit. Use a trivet for hot pans and a board for chopping.

              Which edge?

              • Postformed: the laminate wraps a soft, rounded front. Classic and hard-wearing.
              • Square edge: a sharp, modern line with a matching edge strip.
              • Compact: 12mm solid board, slim and waterproof.

              Fitting in four steps

              • Measure, then cut face down with a fine-tooth blade.
              • Lay it on the units and screw up through the brackets.
              • Seal the cut edges, then fit the upstand and end caps.

              How to measure

              • Measure each wall run along the back, in millimetres.
              • Add about 50mm to every run so you can trim to a clean fit.
              • In an L-shape, let the longest run go into the corner.

              Size guide

              • Worktops come 3000mm or 4100mm long and 600mm deep.
              • Breakfast bars are deeper: 665mm or 900mm, for islands and overhangs.
              • Buy a length that covers your run, then cut it to fit.

              Why you’ll love it

              • Black marble with gold and white veining

                Near-black ground crossed with gold and white veining, inspired by the Portoro marble quarried in Liguria.

              • Enhanced Semi Matt finish

                Duropal’s MS Enhanced Semi Matt texture, a smooth low-sheen finish. It resists stains and everyday scratches, and never needs sealing.

              • Everything matches

                Nero Portoro comes as 20mm square edge worktops, 670mm and 900mm breakfast bars, plus a matching upstand (4100 x 120 x 19mm), a matching splashback (4100 x 640mm), so the whole kitchen is one decor.

              Dark marble that does the talking

              Portoro is a black marble with golden veins, usually seen in hotel bars and high-end bathrooms. In a 20mm slim profile it makes a striking island top or breakfast bar, and works best against pale cabinets and brass or gold hardware.

              How to fit

              Fitting Nero Portoro

              Most straight runs of Nero Portoro are a weekend job. Black decors show chipboard at any unsealed cut, so finish every cut end with the matching 25mm edging rather than leaving it to silicone.

              What you’ll need

              Most homes have these already:

              • Pencil
              • Drill driver
              • Circular saw or jigsaw
              • Straight edge or spirit level

              0330 000 0000Email us
              What sizes does Nero Portoro come in?

              Prices include VAT and free delivery: Worktop 4.1m (20mm square edge) £304.75; Breakfast bar 900mm (20mm square edge) £483.26. Other sizes are available on request.

              Is Nero Portoro square or rounded edge?

              Square edge only, in 20mm. Finish any cut end with the matching edging strip so the core is sealed and the decor carries round the end.

              How do I join two lengths of Nero Portoro at a corner?

              Square edge worktops can be butt-jointed: one length runs into the corner and the other meets it square. Hold the joint with connector bolts underneath and seal it with colour-matched joint sealant. A mitre with a worktop jig also works for 38mm.

              Can I have an undermount sink with Nero Portoro?

              Not with the laminate version. Nero Portoro is also made as a 12mm compact worktop, which is solid all the way through, so the sink cut-out can be polished and the sink fixed underneath. Ask us for compact sizes and prices.

              What colour cabinets go with Nero Portoro?

              Light oak, cream and white cabinets give the strongest contrast. Brushed brass taps and handles echo the gold veins.

              Is there a matching upstand and splashback?

              Yes: a matching upstand (4100 x 120 x 19mm), a matching splashback (4100 x 640mm). Full-height panel behind the hob or sink.

              How do I clean Nero Portoro?

              Wipe with warm water and a little washing-up liquid, then dry. For limescale around the tap, use a diluted vinegar solution and rinse. Avoid abrasive pads and bleach-based sprays left to sit.

              How heavy is a Nero Portoro worktop?

              The worktop 4.1m (4100 x 640 x 20mm) weighs roughly 35kg, so it is a two-person lift. It arrives as one full length, so check there is a clear route through the door and around corners.

              Can I see Nero Portoro before I order?

              We don’t sell samples, but the decor code is S63028 MS from Duropal, so a kitchen showroom that stocks Duropal can show you the real thing. The close-up photos on this page are true to colour on most screens.
