Size

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 Portland, 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 Portland, 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 Portland 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.

            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

              Portland is simple to look after: wipe with a damp cloth and diluted detergent, then dry to avoid tide lines on the pale grey. Pans belong on a trivet, and a fine pad refreshes a cut-out edge.

              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.
              More on edges and thickness

              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.
              Read the full fitting guide

              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.
              Full measuring guide

              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

              • Cast concrete with faint streaks

                Horizontal cloud-like streaks run through a pale grey that leans very slightly green. It looks like smooth cast concrete rather than rough aggregate, calm across a long wall.

              • Solid board, slim front

                The compact board is one dense layer, so the front edge is only 12mm. That is why an undermount sink can sit below a polished cut-out here.

              • Sibling of the 38mm and 22mm laminate

                Portland is also made as 38mm postformed and 22mm square edge laminate. Use the compact where you want a slim edge and a solid core.

              A pale industrial grey for modern rooms

              Portland suits loft-style kitchens, handleless doors, brushed steel appliances and pale timber. It also calms a room full of colour, since the pattern is faint, horizontal and very even. In a utility room or rental, the pale cloudy face is practical because it needs no matching. Fitters prefer one slim profile that runs continuous along a wall, with no pattern to match.

              How to fit

              Fitting Portland

              Portland has soft horizontal streaks, so run both lengths in the same direction across a joint. The 12mm board is glued and jointed, not screwed, so dry-fit it first and have clamps or weights ready.

              What you’ll need

              0330 000 0000Email us
              What length and depth does Portland have?

              Every format is 4100mm long and 12mm thick, with depths of 650mm for the worktop, 950mm for the bar and 1300mm for the full sheet.

              Is an undermount sink possible with Portland?

              Yes. The board is solid, so the cut-out is polished and left exposed. The laminate Portland versions would need inset sinks.

              Is it a true concrete look?

              It reads as smooth cast concrete: soft streaks, no stones or chips. Pale and cloudy, it is calmer than darker concrete decors.

              What colours of cabinet go with it?

              Matt white, sage, charcoal and pale oak all work, with black or steel handles. A touch of warm timber softens the grey.

              How does it compare with the 22mm laminate?

              Laminate Portland in 22mm square edge has a chipboard core and a chunkier front. The compact version is 12mm, solid throughout and suited to an undermount sink.

              Can I get an upstand in the same decor?

              Yes. Portland has a 4100mm upstand that is 100mm tall and 12mm thick, to finish the wall edge. A splashback is not part of this decor, so plan tiles or paint.
