Kronospan Finesse · K350 RT· Rust

Concrete Flow Laminate Worktop

A pale grey concrete effect with soft vertical streaks, like cast concrete lifted from a timber mould. This laminate worktop is a 38mm square edge board, with breakfast bars, a 20mm upstand and a double-sided splashback in the same decor.

Thickness and edge
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 Concrete Flow, 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 Concrete Flow, 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

      It's double-sided: Rusty Flow is on the reverse, so you can choose which way round to fit it.

      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 Concrete Flow 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

              A damp cloth and warm soapy water are enough for this pale grey surface. Dry it afterwards to avoid streaks. Keep hot pans off it by using a trivet.

              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.

              • 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

              • Pale concrete with vertical streaks

                A light grey base with soft, vertical streaks and faint cloudy patches, like board-marked cast concrete. It is calm and industrial, and its pattern runs down the width of the board.

              • Rust texture

                The RT finish is Kronospan’s Rust texture, despite the pale colour. The laminate resists stains and everyday scratches, and unlike poured concrete you never need to seal it.

              • Rusty Flow on the reverse

                The splashback is printed on both faces, with Rusty Flow, code K351RT, on its reverse. It is 4100 x 640 x 10mm, and the upstand is 4100 x 100 x 20mm.

              Soft industrial grey for loft and modern spaces

              Concrete Flow suits loft-style and Scandinavian kitchens, with black frames, pale timber and matt grey units. The square front edge supports that architectural look, and the pale tone keeps a loft or basement kitchen feeling bright. Landlords and fitters will find one 38mm build easy to specify across several flats. For contrast, the warmer Rusty Flow on the splashback reverse brings a rust-toned accent without a separate order.

              How to fit

              Fitting Concrete Flow

              Concrete Flow has a flat square edge in 38mm. Streaks run across the width, so keep every board the same way up. Corners can be butt-jointed, and each cut end needs the 43mm edging strip.

              What you’ll need

              Most homes have these already:

              • Pencil
              • Drill driver
              • Circular saw or jigsaw

              0330 000 0000Email us
              What are the Concrete Flow board sizes?

              Worktops are 38mm thick and 600mm deep, supplied at 3000mm and 4100mm. Breakfast bars are 4100mm long and available at 665mm or 900mm. This decor is square edge only.

              Is the Rust finish orange?

              No. Rust is the name of the texture, coded RT, not a colour. This decor is pale grey, while Rusty Flow, its splashback reverse, is the warmer, rust-toned partner in the pair.

              What goes on the other face of the splashback?

              Rusty Flow, code K351RT. If you want a worktop and splashback in a single pale grey, fit the Concrete Flow face outward. Turn it over for the warmer contrast behind the hob.

              Which cabinets suit pale concrete?

              Matt black, slate grey and white handleless units all work, as do pale oak fronts. Black taps and steel fittings suit the industrial feel.

              How is the front edge finished?

              The front is flat with a 1.5mm radius in ABS. Cut ends take the 1300 x 43 x 1.5mm matching strip, ironed on and filed flush, so every visible edge matches.

              Does this concrete look allow an undermount bowl?

              No. An undermount cut-out would expose the chipboard core to water. Choose an inset sink, sealing the cut edge with silicone. A compact 12mm version is not offered.
