Trade sealant ranges from Mapei, Illbruck, CT1 and Arbo run to dozens of shades — greys, anthracites, beiges, browns, blacks, stone tones, and grout-matched colours designed to pair with specific tile adhesive and grout ranges. The work is the same high standard of preparation and application as any other joint; the difference is in the specification stage. We identify the grout, worktop, frame or cladding reference, select the closest sealant shade, confirm it with you before ordering, and then apply and tool the bead so both the colour and the profile read as part of the finish. ### Who it is for Homeowners who have just spent money on tiling, stone worktops, anthracite windows or a new bathroom and do not want a white line running through it. Colour matching is the difference between a joint that looks like a repair and a joint that looks like it was designed in. Commercially: main contractors, developers and fit-out contractors on office refurbishments, new builds, refurbishments and schools, where sealant lines sit in full view against feature tiling, stone floors, dark frames or cladding panels, and where the client will notice a mismatched bead on the handover walk-round. ### When it is needed Whenever the joint is visible in a finished space and the adjacent material is not white: dark or coloured grout, anthracite and bronze window frames, stone and quartz worktops, feature tiling, coloured cladding panels, resin and vinyl floor finishes with a defined colour, and any joint that runs across a wall or floor at eye level. It is also the fix for joints that were originally sealed in white against a dark finish — a very common inheritance in bathrooms and on facades — where nothing is wrong with the joint except that it is impossible to look at anything else. ### Why professional matching matters Colour is harder than it looks. Sealant cures slightly different from wet, colours read differently in artificial and daylight, and a shade that looks identical to a grout sample in a merchant's catalogue can be a full tone out on the wall. Selecting from experience — and confirming the choice before hundreds of metres are ordered — avoids a result that is worse than plain white. The other half is that colour hides nothing. A dark bead makes width inconsistency and poor tooling more obvious, not less, because the eye follows the line. Matched sealant only works when the application underneath it is straight, even and cleanly cut in. 02 Recent work ## Colour-matched silicone sealant — completed jobs ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) [See the full gallery](/our-work) 03 What it costs to leave it ## A failed seal never stays a small problem A mismatched sealant line is the cheapest way to spoil an expensive finish. It is also the one detail nobody photographs when a job is signed off, and the one that gets mentioned every time the room is used. ### A premium finish devalued Stone worktops, feature tiling and dark frames lose their impact when a hard white line is drawn around them. The materials still cost what they cost; they just stop looking like it. ### Rework on a completed fit-out Changing a bead colour after the fact means cutting out fully cured sealant against finished surfaces — slower, riskier and more expensive than getting the shade right at the start. ### Dirt shows on the wrong colour White sealant against dark tiling and grout shows every trace of dirt at its edges, while a matched or darker bead keeps looking clean far longer between deep cleans. ### Mistakes we get called out to fix - Defaulting to white sealant against dark grout, frames or worktops because that is what was on the van. - Using clear silicone to avoid the colour decision — clear beads yellow, show trapped dirt and highlight every bubble. - Choosing a shade from a printed chart rather than against the actual grout, stone or frame on site. - Assuming grey is grey — sealant greys run warm and cool, and the wrong temperature reads as a mistake rather than a match. - Applying a dark bead over sloppy preparation, where the strong colour makes every wobble and width change obvious. 04 How a job runs ## The order of work, start to finish ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) Step 01 — Identify the finish 1. 01 ### Identify the finish We look at the actual grout, worktop, frame, tile or cladding — and its reference where available — rather than working from a description. ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) 2. 02 ### Shade selection & sign-off We propose the closest available shade from our product ranges and confirm it with you in writing before ordering anything. ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) 3. 03 ### Preparation Old sealant removed in full, joint faces cleaned and dried, backing rod fitted where the joint is deep, and adjacent finishes masked. ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) 4. 04 ### Application & tooling Bead gunned in a continuous pass and tooled to a consistent concave profile — colour matching only works over clean, even application. ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) 5. 05 ### Daylight check & clean up We check the cured line in daylight as well as artificial light, remove masking, and leave no residue on the surrounding finish. ![Colour-matched silicone cartridge used beside a yellow glass splashback](/__l5e/assets-v1/42471476-abc6-4674-8631-6e87af0c4057/colour-matched-silicone-sealant-01.jpg) 05 What you get ## The difference a properly detailed finish makes ### The finish reads as one piece A matched bead lets tiling, stone, joinery or cladding carry the space instead of being outlined in white. ### Looks clean for longer Matched and darker shades disguise the edge dirt that makes white sealant look tired within months. ### No compromise on performance Colour-matched products are the same trade-grade silicones — mould-resistant, weather-grade or low-modulus as the application demands. ### Right first time Shade signed off before ordering, so nobody is cutting out cured sealant from a finished room to change the colour. ### Works inside and out Matching applies equally to bathrooms and worktops and to render, brick, stone and cladding joints across a facade. ### Client-ready handovers On commercial fit-outs, matched joints remove one of the easiest things for a client to pick up on a walk-round. 06 In detail ## Materials, methods and the variations we cover ### Products and available shades Colour-matched work draws on the coloured sealant ranges within Mapei, Illbruck, CT1 and Arbo. These run well beyond white and clear: greys from light silver through to anthracite, blacks, browns, beiges, sand and stone tones, and grout-referenced colours designed to pair with specific tile adhesive and grout systems so the sealed movement joint in a tiled floor matches the grouted joints around it. Crucially, colour is available across product types. That means the bead in a wet room can be both anthracite and sanitary-grade mould-resistant; an external facade joint can be matched to the cladding and still be a UV-stable, low-modulus weather-grade sealant; a trafficked floor joint can be matched to the resin finish and still be a hard-shore product that carries wheel loading. Colour never comes at the cost of the correct chemistry — if a shade is not available in the right product for the application, we say so rather than downgrade the sealant. ### Method: matching accurately We match against the material itself, in the light the joint will live in. Grout is the easiest reference because manufacturers publish paired sealant shades; stone, quartz and timber need judgement, because a single slab contains several tones and the right answer is usually the mid-tone rather than the lightest or darkest. Frames and cladding are often specified by RAL, which narrows the choice quickly. Two practical points shape the result. First, sealant dries slightly different from its wet colour, so selection is made on cured references rather than on the bead as it comes out of the nozzle. Second, colour amplifies workmanship: a strong shade against a pale tile creates maximum contrast at the joint edges, so masking discipline, consistent bead width and immediate tooling matter even more than usual. A matched bead applied badly looks worse than white applied well. ### Where colour matching gets used Tiled bathrooms and wet rooms with coloured or dark grout. Shower trays, enclosures and screens against dark tiling. Kitchen worktops in quartz, granite, solid surface and timber, including sink and hob cut-outs, upstands and island returns. Window and door perimeters on anthracite, grey, black, bronze and timber frames, internally and externally. Movement joints in large tiled and resin floors. Skirting and floor-line mastic against coloured flooring. Cladding, rainscreen and curtain walling joints matched to panel colours. Masonry and render joints matched to brick or render tone. Feature walls, stone cills and copings. It is equally useful in reverse: where a joint should read as a deliberate line — a shadow gap detail or a designed expansion joint in a floor — we can specify a contrasting colour so the joint looks intentional rather than accidental. ### Domestic and commercial application In homes, colour matching is usually the last decision in a bathroom or kitchen project and the one with the highest visual return for its cost. We take the grout or worktop reference, propose a shade, confirm it, and seal in a single visit. On commercial fit-outs, matching is a specification item that needs settling early because coloured sealant is often ordered rather than stocked. We agree shades against the finishes schedule at quote stage so material is on site when the programme reaches us, avoiding the classic outcome of a whole floor sealed in white because the matched product was a week away. 07 Questions ## What customers ask before booking Does colour-matched sealant cost more? The material can cost a little more than standard white, and it usually needs ordering rather than picking up. It is quoted with the job, free of charge, and the difference is small relative to the finish it protects. Can you match my exact grout? In most cases yes — the major sealant ranges include grout-referenced colours. Tell us the grout brand and shade, or send a photograph and a sample area, and we will confirm the closest match before ordering. How close is the match, realistically? Against a published grout pairing it is very close. Against natural stone, quartz or timber it is a judgement of the mid-tone rather than an exact copy, because the material itself varies. We agree the shade with you before committing to it. Is clear silicone a good alternative? Rarely. Clear beads yellow with age, show every trapped bubble and highlight dirt behind the joint. A matched opaque colour almost always looks better for longer. Is coloured sealant as durable as white? Yes — these are the same trade-grade products, available as mould-resistant, weather-grade, low-modulus and hard-shore variants. Colour is a pigment choice, not a downgrade in performance. Will the colour fade outside? External colour-matched silicones are UV-stable and hold their colour well. Very dark shades on south-facing elevations will age fractionally over many years, as any coloured material does. Can you change the colour of existing joints? Yes. The existing bead is cut out in full, the joint prepared, and the new matched sealant applied. Painting over old sealant is not an option — paint does not adhere to cured silicone. How long does the work take? The application takes no longer than standard sealing; the lead time is the material. Where a colour needs ordering we build that into the date we give you, so allow a few days from sign-off on non-stock shades. Do you use colour matching on commercial projects? Regularly — facades, feature tiling, resin floors and washroom packages. We settle shades against your finishes schedule at quote stage so material arrives ahead of our programme slot.
