This page preserves a PG252 digital-print surface record published in November 2016 and corrects its editorial intent from the legacy “Grainte/Graint” spelling to granite-look. The pictured product is terracotta with a speckled stone-look face, not quarried granite. Its visual resemblance does not transfer granite composition, properties, quarry variation, price or project performance to the terracotta unit.
This guide focuses on speckle scale, colour distribution, sample size, repeated panels and elevation coordination. Use the main Terracotta Rainscreen and Stone Surface pages for current product/system coverage, and the Digital Inkjet Terracotta resource for broader printed-surface selection.
Archived PG252 product and commercial record
The fields below are retained for traceability. The current-use column explains what must be checked before any archived value is used on a live project.
| 2016 field | Archived value | Current-use boundary |
|---|---|---|
| Item / model | PG252 | Use as a legacy reference; confirm that the code remains active and still identifies the same body and printed surface. |
| Size | Customized | No dimensions were stated. Confirm available module, geometry, tolerances, edge conditions and fixing interface. |
| Color | MIX | Define current background tone, speckle palette, acceptable range, distribution and production-lot approval method. |
| Surface finish | 3D Inkjet | Confirm the present face construction, printing/firing route, relief, sheen, artwork scale, repeat and compatibility with the selected body. |
| Material | Natural Clay | A historical body description; the face is a granite-look terracotta finish, not natural granite or environmental evidence. |
| Weight | 31 kg/m² | The source cites no product configuration, test method or tolerance. Obtain the current declared value for structural and logistics work. |
| Water absorption | Less than 0.5% | The source cites no standard, specimen, laboratory or report. Require current scoped technical evidence before relying on this value. |
| Thickness | 18 mm | Confirm the current profile and local tolerances; the image edge is not a dimensioned section and this value cannot transfer to another item. |
| Minimum order | 1,500 m² | A historical commercial term only. Request a current quotation for the chosen artwork, finish, module, quantity and schedule. |
| Lead / delivery time | 35 days | A historical estimate only. Current timing depends on sample approval, production, quantity, packing, destination and logistics. |
| Legacy certification text | CE, ISO 9001:2008 | Not presented as current. Request each applicable document with holder, scope, site, product, issuer and validity. |
| Legacy order route | Order button enabled to old `/contact-us/` URL | Use the current Contact page for project requests. |
Preserved granite-look item board
Readable legacy item references on the board:
PG258
PG252
PG008
PG727
PG725
The board is a historical shortlist, not an approved current range. Monitor calibration, compression, lighting and photography affect perceived colour, and the small swatches do not establish speckle size at full panel scale. Do not transfer PG252 specifications to the other five codes or assume they share one body, pattern file or module.
Coordinate speckle scale from sample to elevation
Define background and particles
Describe the base tone, light/dark particle colours, density, contrast and any directional movement. “Granite look” alone is too broad to identify the intended surface.
Check scale on a full-size unit
Measure visual intent against the actual panel module. A small chip or web thumbnail can make coarse particles look fine and cannot show how the pattern reads across the full face.
Review near and far readings
Inspect at close range, typical pedestrian distance and the intended facade viewing distance. Fine speckle may merge into an overall tone, while high-contrast particles may remain prominent.
Expose digital repetition
Place several panels together and identify repeated clusters or tonal zones. Confirm current pattern variants and define their distribution before approving a large elevation.
Coordinate joints and cuts
Review the surface with the proposed module, joint width/color, openings, corners, cut edges and returns. Joint rhythm may dominate or fragment a small-scale stone visual.
Set a lot approval range
Approve dated physical samples or a range board and define acceptable background, particle contrast, sheen and surface variation. A single ideal piece does not represent the whole order.
Use staged samples and an elevation reference
- Archive shortlist: use PG009, PG258, PG252, PG008, PG727 or PG725 only to identify an initial visual direction.
- Current labelled sample: obtain the exact item, body, surface, dimensions/profile, sample date and production status.
- Full-size surface review: inspect the complete face, edge/profile, sheen, particle scale and color balance in relevant lighting.
- Repeated panel mock-up: assemble enough units to expose pattern repeats, tonal grouping, joints, cuts and corners.
- Elevation coordination: record permitted variants, orientation or rotation, distribution zones and transitions to adjacent materials.
- Production benchmark: retain the signed sample/range and agree how the current lot and replacement units will be compared.
| Approval field | What to record | Why it matters |
|---|---|---|
| Product identity | Current item, clay body, surface, dimensions/profile and fixing route | Connects the appearance reference to the selected terracotta unit. |
| Colour balance | Background hue/value plus light, mid and dark particle colours | Distinguishes the intended palette from a generic granite label. |
| Speckle character | Particle scale, density, contrast, distribution and directionality | Controls how the finish reads at sample and facade distances. |
| Repeat strategy | Current variant IDs, permitted placement and repeated-panel mock-up | Reveals recognizable clusters before elevation approval. |
| Edges and joints | Factory/cut edges, profiles, corners, returns, joint width/color and adjacent materials | Tests visual continuity in the real assembly context. |
| Range and lot | Accepted variation set, date, revision and production comparison method | Creates a traceable benchmark without promising exact identity. |
Coordinate surface approval with facade engineering
A printed terracotta unit works with clips, rails, brackets, anchors, joints, cavity, insulation, air-and-water control layers, flashings, fire stopping and the supporting wall. Stone-look sample approval cannot replace engineering or compliance review for the actual assembly.
Define structural actions, wind, impact, moisture, fire, thermal, acoustic, movement, durability, access, cleaning and applicable-code requirements for the proposed configuration. Use current product data, calculations, details, samples and project-specific testing where required. Appearance does not establish resistance to stains, chemicals, weather or UV exposure, and no environmental, price or natural-stone-equivalence conclusion should be inferred.
Archived application and project claims need a current review
The 2016 article marketed the product for new and renovated exterior walls; metro, railway, tunnel and other underground projects; European- or American-style architecture and villa walls or roofs; ceilings; office buildings and commercial podiums; interior walls; and surgery rooms, clean rooms, pharmaceutical facilities and food-production workshops.
That list is preserved as historical context, not approval evidence. Each use needs its own review of substrate, exposure, fixing, movement, structural actions, fire strategy, enclosure details, access, hygiene or emissions criteria, cleanability and governing codes.
Use the Architectural Terracotta Gallery for identified precedents. A precedent may inform visual discussion, but its engineering, finish approval and performance conclusions do not automatically transfer to a new building.
Request current PG252 or related surface samples
Send the project location, elevation details, target module, preferred archived surface direction, viewing distances, joint/corner conditions, estimated quantity, required standards, delivery destination and programme. Ask whether the PG references remain available before naming a code in the specification.
