VISAGE STENCIL BOSTON BRICK 15pcs/15m2

Brick effect on a rendered wall is a two-colour operation: the primer colour becomes the mortar joint and the plaster becomes the brick. This pack is the contemporary-bond half of the concrete effect render range at Renders World, and every figure below is read from the Ceresit sheet for the plaster it patterns.

Where the Boston Brick Pattern Suits a UK Rendered Elevation

Visage Stencil Boston Brick patterns Ceresit CT 60 VISAGE 0.5 mm plaster, a render Henkel declares under EN 15824 and consumes at roughly 1.5–2.0 kg/m² over a stencil, on facades built to imitate clinker brick. The sheet scopes that plaster tightly, and the scope decides whether the pattern belongs on your wall.

• Insulated facades: CT 60 0.5 mm is named as a facade plaster within Ceresit Ceretherm ETICS using expanded polystyrene boards and mineral wool, so stencil work sits on a finished, primed reinforced layer rather than on the insulation itself.
• Concrete and rendered walls: concrete over three months old and cement or cement-lime plasters over 28 days old, both at moisture of 4% or below, primed with CT 16 priming paint.
• Reinforced basecoat layers: mesh-reinforced layers made of Ceresit CT 80, CT 85, CT 190 or ZU mortar, primed with CT 16 once more than three days old.
• Indoor surfaces only: gypsum substrates below 1% moisture, chipboard, gypsum-fibre and drywall boards, and sound paint coats — the sheet restricts every one of these to the inside of buildings.

That last line is the one worth carrying into a specification. A stencilled feature wall in a hallway is a documented use of the plaster; the same boarded substrate outdoors is not, and the sound route there is a rendered or ETICS build-up beneath the pattern.

Why Specifiers Choose a Stencilled Brick Effect Here

The appeal of a stencil is that the brick character is made in a material the wall was receiving anyway, and four documented properties carry the decision.

• Assessed inside a named system: the plaster holds a European Technical Assessment as part of the Ceresit Ceretherm Visage system, ETA 11/0395, with Declaration of Performance 00288 to EN 15824.
• Weather performance stated by category: water absorption cat W2, water vapour permeability cat V2 (0.14 ≤ Sd < 1.4 m) and adhesion of 0.6 MPa, all to EN 15824, with a BioProtect formula the sheet describes as resistant to fungi, mould and algae.
• Twelve Visage colours plus the full Colours of Nature palette: the brick tone is chosen from the plaster, so one stencil pattern serves every scheme on the palette.
• A stated renovation route: Ceresit names CT 42 and CT 44 acrylic paints and CT 48 silicone or CT 49 nanosilicone paint for renovating the plaster later, which keeps a stencilled facade on an ordinary repaint cycle.
• Priced by area, not by brick: Renders World lists the pack at £116.70 per 15-sheet pack, in stock in August 2026 — 116.70 ÷ 15 m² = £7.78/m² of patterned facade, before the plaster.

What the Manufacturer Sheet Specifies Behind the Pattern

The stencil sheets themselves carry no published performance data. Everything in the table below belongs to the plaster pressed through them, which is the honest way to read it on site: the plaster's limits govern the working day.

Reaction to fire follows the same discipline. Ceresit classifies the plaster only inside complete systems to EN 13501-1 — B-s1, d0 in Ceresit Ceretherm Visage and Universal EPS, and A2-s1, d0 in Ceresit Ceretherm Universal MW. Those classes describe those named build-ups; the stencil sheets have no class of their own and none is published here.

Applying CT 60 VISAGE 0.5 mm Through the Boston Sheets

Ceresit sets the brick effect out as a fixed sequence, and the joint colour is decided before any plaster is opened. The full method across both stencil patterns sits in the brick and timber stencil methods guide; the steps below stay on this pack.

1. Prime to the joint colour. Absorbent surfaces take CT 17 first, then CT 16 priming paint after at least two hours, and the sheet is explicit that the CT 16 colour should match the designed joint colour. Ceresit recommends Etna 1, Etna 5, Nebraska 3, Kalahari 1, Savanne 4, Colorado 4 and Texas 5 from Colours of Nature for joints.
2. Let the primer dry completely. The plaster goes on only after full drying of CT 16 — Renders World holds this stage in the exterior render primers range, at exterior render primers.
3. Press the sheets down properly. Remove the protecting tape and press each sheet thoroughly to the surface, with a rubber roller for example, so plaster cannot flow underneath and lift it. Fix sheets only on the area you will plaster straight away.
4. Stir and apply. Stir the container thoroughly; consistency may be adjusted with a small volume of clean water and a second stir. Apply uniformly with a steel long float held at an angle.
5. Texture immediately. Texture is taken right after application, by smoothing with the steel long float or by texturing. Machine application is possible.
6. Lift after initial setting. Remove the stencils once the plaster has initially set, pulling each sheet gently downward and partially rather than in one movement.

Quantities follow from the consumption line: 15 m² × 1.5–2.0 kg/m² = 22.5–30 kg, so one 25 kg container of plaster covers a full pack at the lower rate and a second is needed at the upper. Order the second container where the template is running at the thicker end.

Site Notes: Pressing, Peel Timing and Sheet Life

Two instructions on the sheet change how a job is planned, and both are easy to design around once they are known.

• Each sheet is specified for the surface it is pressed to. Ceresit states plainly that stencils peeled off earlier are never used on other surfaces — so the pack is sized as 15 sheets for 15 m², one pass, and the sheet count is ordered from the plastered area rather than from a reuse cycle. Measuring the elevation properly at quotation stage is what makes this straightforward.
• Panel size follows the wet stage. Because texture is taken immediately after application and open time is around 15 minutes, the number of sheets fixed at once is set by how much wall can be plastered, textured and lifted inside that window — plan bays a two-person crew can finish, and the joints come out clean panel after panel.
• Conditions govern the whole sequence. Hold air and surface temperature between +5 °C and +25 °C with humidity below 80% from priming through to lifting, keep the work off walls in strong sun, and protect the finish from rain for the first 24 hours.
• Work one production batch per elevation. The sheet asks for one surface to be plastered with material carrying the same production unit number, which is the detail that keeps shading consistent across a gable.

Timing and UK weather across the wider decorative range are covered in the concrete effect render application guide, which works through substrate condition in more depth.

Which of the Two Visage Brick Patterns to Order

Ceresit publishes two brick stencils, and both are sold here in the same 15-sheet, 15 m² format at the same price, over the same plaster and the same primer. No document retrieved this session describes the bond geometry of either sheet, so the pattern is chosen against the manufacturer's swatch images rather than against a specification — and that is the only variable between them.

Pattern	What is documented	How the choice is made
Boston Brick stencil	15 sheets, 15 m², CT 60 VISAGE 0.5 mm, CT 16 primer, 12 colours, £116.70 August 2026	Compare the Boston swatch against the elevation and the joint colour
Visage Stencil London Brick pack	Identical format, plaster, primer, palette and price	Compare the London swatch on the same two variables

Ordering the Boston Stencil: A Four-Point Check

• Confirm the substrate is one the plaster is scoped to. ETICS on EPS or mineral wool, concrete, cement plasters — with boards and gypsum kept to interior work.
• Fix the joint colour first. The primer is the mortar line, so the CT 16 shade is a design decision made before the plaster colour is confirmed.
• Order sheets to area, plaster to consumption. One pack per 15 m², and 22.5–30 kg of plaster behind it.
• Check the alternative pattern before committing. The London Brick pack is identical in system terms, and Renders World stocks Atlas Base Coat Paint 10 L as the tinted base for its concrete-effect work — Ceresit names CT 16 for this plaster, so confirm the pairing on the order rather than assuming it.

Where the brief only needs a coloured, weatherproof facade with no pattern stage, the wider concrete effect render collection covers the smooth and timber routes instead.

FAQ — Coverage, Substrates and Sheet Life

How many packs and how much plaster does an elevation take?

One pack is sold as 15 sheets for 15 m², so divide the patterned area by 15 and round up, allowing for cuts at reveals. Plaster follows the consumption line: at 1.5–2.0 kg/m², a 15 m² pack needs 22.5–30 kg, which is one or two 25 kg containers depending on how thickly the template runs.

Can the stencils be used over an external wall insulation system?

Yes, on a completed build-up. Ceresit names CT 60 0.5 mm as a facade plaster within Ceretherm ETICS using expanded polystyrene boards and mineral wool, applied to the mesh-reinforced layer once it is more than three days old and primed with CT 16.

Can a peeled sheet be pressed onto the next panel?

The sheet instructs that stencils peeled off earlier are not used on other surfaces, so plan the job on one pass per sheet. That is why the pack is designated 15 sheets to 15 m², and why the area measurement at quotation stage is the number that matters.

When should the work be held off?

Below +5 °C or above +25 °C, at relative humidity of 80% or more, on walls in strong sun where the plaster would dry too quickly, and where rain is likely inside the first 24 hours. Scaffold sheeting is recommended, and the finish behaves predictably once those four conditions are met.

How is a stencilled facade maintained later?

Ceresit names CT 42 and CT 44 acrylic paints and CT 48 silicone or CT 49 nanosilicone paint as the renovation route for the plaster. No service life in years appears on the sheet, so the practical answer is an ordinary facade repaint cycle rather than a stated interval.
