Description
Stencilled clinker brick on a rendered wall is a two-material job: the stencil sets the pattern, the render fills it, and the mortar line is the colour of the primer underneath. Renders World holds this grade in the brick, wood and concrete effect render collection as the fine 0.5 mm acrylic made for stencil work.
Where CT60 Visage Fits on Stencilled Brick and Stone Walls
CT60 Visage acrylic render 0.5mm is a ready-mixed acrylic decorative plaster with a declared consumption of 1.5–2.0 kg/m² at roughly 1 mm stencil depth, laid through clinker-brick stencils to build a brick-effect facade. The data sheet places it in three settings.
- Facades within Ceresit Ceretherm ETICS build-ups on expanded polystyrene boards, applied onto a mesh-reinforced layer of CT 80, CT 85 or ZU that is more than three days old and primed.
- Solid mineral substrates: concrete over three months old and cement or cement-lime renders over 28 days old, in both cases at moisture of 4% or less.
- Interiors only: gypsum plaster below 1% moisture, plus chipboard, gypsum-fibre and plasterboard, and sound existing paint coatings with good adhesion.
The stencil is what makes the grain choice matter. At 0.5 mm the material fills a template crisply and releases cleanly, which is why the sheet recommends this grade for clinker-brick and natural-stone patterns rather than the coarser textured plasters in the same family.
Why Specifiers Choose This Stencil-Grade Acrylic Plaster
- Texture comes from the trowel, immediately: the surface is finished by smoothing with a steel trowel straight after laying, so the pattern depends on the stencil rather than on a second product or a sealer coat.
- Water absorption class W2 under EN 15824, with the sheet also declaring uptake below 0.5 kg/m² after 24 hours under ETAG 004 and rain resistance after roughly 24 hours.
- Vapour class V2 under EN 15824, the band of 0.14 ≤ Sd < 1.4 m, so moisture in the wall still moves outward through the finish rather than being sealed behind it.
- BioProtect formulation: Ceresit states protection against fungal, mould and algal colonisation, which on a mortar-jointed pattern with many shaded edges is where growth would otherwise start.
- Twelve Visage shades plus the full Colours of Nature palette, with adhesion declared at 0.6 MPa to EN 15824 and interlayer adhesion after ageing at 0.08 MPa or above under ETAG 004.

Coverage follows the consumption line rather than the pack label: 25 kg ÷ 2.0 kg/m² = 12.5 m² at the heavier rate, and 25 kg ÷ 1.5 kg/m² = 16.7 m² at the lighter one. Order against the heavier figure, because a deeper stencil template consumes more material than the sheet's nominal 1 mm.
The λ value of 0.61 W/(m·K) belongs to the render as a finish, so it plays no part in a wall's thermal performance — that work is done by the insulation layer beneath, and any U-value is a calculation on the whole build-up rather than a property of this coat.
How to Apply CT60 Visage Over Clinker-Brick Stencils
Stir the bucket thoroughly first, adjusting consistency to site conditions with a small quantity of clean water only, and never with other plasters, pigments, resins or binders. Rust-prone tools and containers stay off the job.
- Stencil only what will be rendered now: peel the backing tape, position the template to the agreed pattern and press it down firmly, a rubber roller being the reliable way to stop material creeping underneath.
- Lay the render with a steel trowel held at an angle, spreading evenly to the stencil edges across the taped area.
- Smooth immediately to form the texture, since the finish is created at once by trowelling rather than by a later pass. Machine application is also permitted by the sheet.
- Lift the stencils once the render has taken its initial set, and discard each one after use — a template that has already been peeled is never reapplied to another area.
- Break work at the end of a stencil, resuming from that marked point, and keep adjoining working areas joined wet-on-wet.
The 15-minute skinning time is the figure that sizes each panel: it is short, so brief the crew to stencil, lay, smooth and lift in a rhythm rather than taping out a whole elevation first. Never mist the surface with water. The guide to wood and brick stencils for render covers pattern layout and template handling in more detail, and the concrete-effect render application guide carries the trowel technique shared across the range.
How to Prime the Substrate and Colour the Mortar Joints
| Substrate | Age and moisture | Priming route |
|---|---|---|
| Concrete | over 3 months, moisture ≤ 4% | CT 16 quartz primer |
| Cement and cement-lime render | over 28 days, moisture ≤ 4% | CT 16 quartz primer |
| Mesh-reinforced layer, CT 80 / CT 85 / ZU | over 3 days | CT 16 quartz primer |
| Gypsum plaster (internal) | moisture below 1% | CT 17, then CT 16 |
| Boards and sound paint (internal) | fixed per board maker's instructions | CT 17, then CT 16 |
Absorbent substrates take CT 17 first and CT 16 no sooner than two hours later, while hollows and damage are levelled beforehand — CT 29 filler on traditional renders and concrete. Weak layers and elastic, lime or glue-bound paint films are removed completely rather than primed over.
Here is the detail that decides how the finished wall reads: the mortar joint takes its colour from the CT 16 quartz primer, because the primer is what remains visible between the stencilled bricks. Ceresit names seven joint shades from the Colours of Nature palette — Etna 1, Etna 5, Nebraska 3, Kalahari 1, Savanne 4, Colorado 4 and Texas 5. Renders World stocks the quartz-primer side of the exterior render primers range, so the joint colour is chosen at the same time as the brick colour.
Do not confuse that primer with a tone-matched base for the Atlas concrete- and wood-effect products: Atlas Base Coat Paint serves those renders, whereas CT 60 Visage names CT 16 as its own priming mass and CT 17 as the consolidating pre-primer.
Installer Notes on Batches, Sun and Scaffold Cover
- One batch number per plane: the natural fillers can shift appearance and shade between production runs, so buy each elevation together and check the number printed on every bucket.
- Staff the scaffold to the wall: uniform structure depends on having enough hands on each lift to keep the wet-on-wet joins moving.
- Keep off strongly sunlit walls, working the shaded side and following the sun, with scaffold sheeting used as a matter of course during insulation work.
- Protect until fully dry from direct sun, rain and strong wind, which is what preserves both the colour and the crispness of the joint lines.
- Wash tools and fresh splashes with water; cured residue is removed mechanically. Reseal opened buckets tightly and use the contents promptly.
What the Certificates Cover, and at Which Scope
Reaction to fire on this product is a system classification, tested on an assembled build-up, and the render alone carries no class. The sheet declares B-s1,d0 to EN 13501-1 in the Ceresit Ceretherm Visage and Ceretherm Universal EPS systems, and A2-s1,d0 in Ceretherm Universal MW, the mineral-wool system. Quote the class with the system name attached, and take the stricter B-s1,d0 as the figure that applies to the Visage build-up this render belongs to.
- Product level: Declaration of Performance No. 00288 under EN 15824 for external renders on organic binders, which is where W2, V2, 0.6 MPa adhesion and λ 0.61 W/(m·K) come from.
- System level: European Technical Assessment ETA 11/0395 with certificate 1488-CPR-0370/Z and DoP 00431 for Ceretherm Visage, alongside further ETAs for the Universal EPS, XPS, MW and CC Wool Classic systems.
- Impact resistance category II under ETAG 004 as declared on the sheet, while NSAI Agrément assigns impact categories per build-up in each system Detail Sheet — so confirm the category for the specified assembly rather than carrying this one across.
- Irish agrément 09/0340 names Ceresit Ceretherm Visage as one of seven certified ETICS systems against the Irish Building Regulations, with installation by approved installers and a five-year certificate validity; it is an Irish system certificate, not UK product certification.
For a UK specification, ask Renders World for the current version of whichever document the project relies on before the build-up is fixed, since assessments are reissued and the certified scope is the assembly rather than the bucket.
Is This the Right Finish for Your Brick-Effect Facade?
| Route | What the documents support | Choose it when |
|---|---|---|
| CT 60 Visage 0.5 mm with stencils | W2, V2, 0.6 MPa adhesion; 1.5–2.0 kg/m²; joint colour from CT 16 | Clinker-brick or natural-stone patterns, interior or exterior |
| Concrete-effect renders in the same collection | Own sheets, trowel-formed texture, no stencil needed | Fair-faced architectural concrete rather than masonry pattern |
| Timber-effect route in the same collection | Own sheets plus a tinted sealer stage | Wood-grain facades, where a sealer completes the finish |
Specify this grade where the design wants masonry pattern and the wall needs a low-absorption, vapour-open finish; the two stencil sets stocked alongside it, London brick and Boston brick, are the templates the pattern is built from. Deep, intense shades belong on architectural details rather than whole elevations, and the sheet asks for a light reflectance value of HBW 20 or above on full facades, with Ceresit's technical team confirming the system below that — an easy check at quotation stage.
Renders World lists CT60 Visage acrylic render 0.5mm at £65.00 per 25 kg bucket, August 2026, shown as available when the price was read. At the heavier 2.0 kg/m² rate one bucket covers 12.5 m², so £65.00 ÷ 12.5 = £5.20/m² in material, falling to £3.89/m² at 1.5 kg/m²; primer, filler and stencils are priced on their own pages. Where a timber-effect elevation is wanted instead, the guide to sealers for concrete-effect renders sets out that sequence, and the full decorative render range shows the three routes together.
FAQ — Coverage, Primer, Colours and Renovation
How many buckets does a 40 m² elevation need?
Four at the heavier consumption rate: 40 m² ÷ 12.5 m² per bucket = 3.2, rounded up. Deeper stencil templates take more than the sheet's nominal 1 mm depth, so a trial area on the actual substrate settles the figure before the full order, and buying one production batch for the whole plane keeps the shade even.
Which primer does it need, and why does the colour matter?
CT 16 quartz primer, applied to every substrate in the sheet, with CT 17 first on absorbent or gypsum backgrounds. Its colour is not cosmetic: the primer forms the visible mortar joint between the stencilled bricks, which is why seven Colours of Nature shades are recommended for that role.
What conditions does application need?
Dry weather with air and substrate between +5 °C and +25 °C and relative humidity below 80%, and a wall out of strong sun. Surface skinning begins in about 15 minutes and rain resistance arrives after roughly 24 hours, so panel sizes stay small and the work is sheltered until it has dried.
Can it be used inside?
Yes, on gypsum plaster below 1% moisture, on chipboard, gypsum-fibre and plasterboard, and on sound, well-adhered paint coatings, each primed with CT 17 followed by CT 16. Ventilate the room until the odour has gone before handing it back into use, and make sure any area subject to lasting damp has its sealing layers in place first.
How is the finish refreshed years later?
By overpainting, which the sheet gives as the renovation route: Ceresit CT 42 acrylic, CT 48 silicone or CT 49 nanosilicone paint. That keeps the stencilled pattern and its joint lines intact while restoring colour, so a tired elevation is a repaint rather than a strip-back.
