Description
The Fox Wood Imitation Stamp is the hand-sized mould in the wood-effect range at Renders World, sitting in the Atlas wood and concrete effect render range alongside the 2-metre plank format. It presses grain into wet decorative render on the areas a long mould cannot reach.
Where a Hand-Sized Wood Mould Fits on a Render Job
The Fox Wood Imitation Stamp presses a tree-ring pattern into ATLAS CERMIT WN, a factory-made one-coat external rendering mortar to EN 998-1:2016 applied around 4 mm thick and imprinted with a silicone mould before it sets.
That 4 mm layer is what any mould in this system works into, and it explains where a hand format earns its keep. Cermit WN is laid with a smooth float, combed with a 10 mm toothed float, then re-smoothed — and on a reveal, a column or a narrow return there is simply not room to bring a two-metre mould onto the wet face. The hand stamp reaches those areas at the same moment in the same render.
Three situations put this format to work:
- Detail areas on a stamped elevation: window reveals, corners, soffits and narrow piers, worked in the same wet-on-wet pass as the main wall so the joint does not show.
- Feature panels rather than whole facades: porches, entrance bays and plinth sections, where the render is declared for ETICS build-ups using EPS and mineral wool as well as concrete and traditional cement or cement-lime renders.
- Sample panels before the elevation: the card asks for consumption to be confirmed by trial on the actual substrate, and a hand mould is the practical way to run that panel.
Why a Hand Format Earns Its Place Beside the Plank Mould
Most wood-effect facades end up using both moulds, so the question is not which one to buy but what each is for. Four things separate the hand format.
- It reaches what the long mould cannot: a 200 cm face will not turn a reveal or sit on a narrow return, and those areas still have to carry grain if the elevation is to read as one surface.
- An organic ring pattern, not a board: the Fox mould is described by its manufacturer as a stamp for the imitation of tree rings, which is a different visual read from a continuous plank.
- It suits the 20–60 minute window: the render must stiffen and dry slightly at the surface before imprinting, and the card asks for that time to be controlled closely. A light hand tool is easier to bring back to a small area at exactly the right moment.
- Silicone, cleaned the same way: the same washing routine the render card sets for the silicone mould applies here, so adding this tool adds no new consumable and no new procedure.
What the Fox Mould Presses Into: Render Data
The mould has no published technical card of its own. Everything below that carries a figure belongs to the render being imprinted, and each row names what it applies to.
| Parameter | Figure | What it applies to |
|---|---|---|
| Tool type | Stamp for imitation of tree rings | Fox Dekorator tools listing |
| Render thickness | Approx. 4 mm | ATLAS CERMIT WN technical card |
| Aggregate size | Max. 1.0 mm | ATLAS CERMIT WN |
| Wait before imprinting | 20–60 minutes | ATLAS CERMIT WN, weather dependent |
| Render consumption | 2.5–3.0 kg/m² average | ATLAS CERMIT WN, confirm by trial |
| Working temperature | +5 °C to +30 °C | Substrate and ambient, both renders below |
| Alternative render | ATLAS SILKON BA, 1.2 mm aggregate | Silkon BA technical card |
| Release agent | ATLAS anti-adhesive for moulds | Named in the Cermit WN imprinting method |
| Cleaning | Water with detergent, after every session | Mould washing instruction, Cermit WN card |
How to Use the Mould on Cermit WN
The sequence below follows the manufacturer's own order for the render, because the mould only ever arrives at step five. The wider multi-product method belongs to the concrete effect render application guide.
- Prepare and prime: a reinforced ETICS layer built with STOPTER K-50 needs no render primer; the same layer in other Atlas adhesives takes Cerplast from the exterior render primers range. Concrete needs 28 days seasoning below 4% structural moisture.
- Mix: 0.21–0.24 litres of water per kg, or 5.25–6.0 litres per 25 kg bag. Stand five minutes, remix, then use within one hour, re-stirring rather than adding water.
- Lay at 4 mm: smooth float, comb with the 10 mm toothed float at an angle, smooth again.
- Watch for surface set: 20–60 minutes depending on the weather. This is the step that decides grain depth, so a sample panel earns its time.
- Grease the mould, then press: coat the face thoroughly with the Atlas anti-adhesive agent before use, and clear render from the recesses before the next impression.
Both moulds in the range are compared side by side in the wood and brick stencil guide.
Planning Detail Work Around the Main Elevation
On a facade using both moulds, the value of the hand tool comes down to sequencing rather than technique, and three points from the render card decide it.
- Wet on wet, always: the card requires each smoothed section to be joined before it dries, or the junction stays visible. Detail areas are worked as part of the same pass, not saved for the next day.
- Put format changes on planned breaks: stopping points are set in advance at corners, building returns and behind downpipes — the same places a switch from plank to hand mould disappears.
- Protect the work: the surface is shielded from direct sun, wind and rainfall during application and throughout drying, which on detail areas usually means the scaffold sheeting is already where it needs to be.
After 24 hours the render is hard, and after three days at +20 °C and 50% humidity it can take an ATLAS BEJCA tinted impregnant — the step that puts colour into the grain.
Cleaning the Mould After Every Session
The render card is direct about mould care, and it is the one instruction on this page that protects the tool rather than the finish.
- Wash thoroughly with water and detergent after every session, until no release-agent residue remains.
- Do not leave it: incomplete washing risks permanent deformation of the mould and makes a correct texture harder to achieve afterwards.
- Clear the recesses during the work, not only at the end, so each impression stays as crisp as the first.
Choose Between the Hand Mould and the Plank Mould
The two moulds press the same render at the same stage. The decision is format and pattern.
| Your project | Best mould | Standout spec |
|---|---|---|
| Reveals, columns, panels, sample boards | Fox Wood Imitation Stamp | Hand format, tree-ring pattern |
| Long unbroken elevations, repeat plots | 200 × 20 cm Atlas plank mould | 0.40 m² mould face per press |
Order the Mould With the Render It Works Into
A mould on its own produces nothing. The render carries the performance, the release agent makes the lift clean, and the impregnant supplies the colour.
- Main elevations alongside it: most jobs run the long-format Atlas plank mould on the open wall and keep this one for the details.
- Colour after three days: the Bejca options are set out in the sealers for concrete effect renders guide.
- A concrete look instead: where the specification asks for concrete rather than timber, Atlas base coat paint works over the same family of renders.
Order the mould with the render, the release agent and the impregnant from the wood and concrete effect render collection at Renders World, so the whole finish arrives together.
FAQ: Compatibility, Timing, Indoor Use and Care
Which renders can this mould be used with?
ATLAS CERMIT WN is the render whose method specifies imprinting with a silicone mould, at roughly 4 mm with a maximum 1.0 mm aggregate. ATLAS SILKON BA is a modelled silicone render with a 1.2 mm aggregate whose card describes texturing with sponge rollers, brush floats and Venetian trowels rather than a mould — usable for texture, but the imprinting instructions belong to Cermit WN. Tell us the effect you are after and we will confirm the pairing.
Can the finish be used on an interior wall?
Not with Cermit WN — its card routes internal walls to different Atlas products. Silkon BA, by contrast, is declared for internal walls including wet areas such as showers, so an indoor decorative finish is possible on that base. The wood-imprinting method itself is written for the external mineral render, so an interior timber-grain wall is worth discussing before ordering.
How long after laying the render should I press?
Between 20 and 60 minutes, once the material has stiffened and dried slightly at the surface. Warm and breezy conditions shorten it; cool still air extends it. The mixed mortar itself remains workable for one hour, so plan panel sizes around both figures.
How much render do I need for a stamped area?
Average consumption is 2.5–3.0 kg/m² from 25 kg bags. For a 12 m² feature panel: 12 m² × 3.0 kg/m² = 36 kg, so two bags with an allowance for the sample panel. Atlas asks for the exact figure to be established by trial on the substrate you are actually rendering, which is another argument for that panel.
How should the mould be cleaned and stored?
Wash it thoroughly with water and a detergent after every session so no release-agent residue is left, and clear the recesses as you work. The card warns that skipping this risks permanent deformation of the mould, so the five minutes at the end of the day protects the tool for the next job.
