Terracotta panel surface and texture should be specified as measurable visual geometry, not as a loose menu of names. The selected face must be reviewed at project viewing distances, under relevant light and weather, and across a representative production range before it becomes an architectural control.

Replace broad texture names with geometry
Words such as flat, grooved, linear, sanded, wood-like or corrugated can cover very different appearances. Pair the design name with a current code, profile drawing, texture direction, repeat, depth, spacing, edge treatment and physical sample. State which attributes are essential to the concept.
Separate the facing profile from the surface finish. Relief may be formed by the section, while color, sheen or tactile character comes from another process. Confirm which combinations are currently feasible rather than assuming every texture is available on every panel size or profile.
Build a finish schedule with thumbnail references for navigation, but make the current drawing and tagged physical sample the controlling definition. Marketing names may remain useful for discussion; they should not be the only way production, inspection or replacement material is identified.
Judge texture at several viewing distances
Close view
Review tactile character, local marks, edges and the relationship between texture and joint detail.
Mid-range view
Study how repetition, module and shadow create a readable facade pattern around openings.
Long view
Check whether the relief remains legible or resolves into a broader color and tonal field.
Moving view
Consider how directional surfaces change as people approach or travel past the elevation.
Record the intended viewing conditions in the brief. A sample selected at arm’s length can produce a different result across a large elevation, while a dramatic profile shown in close photography may become subtle from the public realm.

Study daylight, orientation and shadow
View full-size samples upright in direct sun, open shade and overcast light. Directional grooves may produce strong bands under grazing light but appear flatter when front lit. Repeat the review for different facade orientations where the same texture is expected to read consistently.
Coordinate architectural lighting where it contributes to the concept. Fixture angle and color temperature can exaggerate relief or shift the perceived surface color. Photographs should document the review, but retained physical samples remain the primary appearance control.
Coordinate module, joints and transitions
Develop elevations at fields, corners, window returns, bases, parapets and changes between textures. Align pattern repeats and texture direction with panel modules and joints. Small offsets at a boundary can become more visible than the texture itself when repeated across the wall.
Resolve special returns, cut edges and closure pieces before release. Confirm that visible geometry remains compatible with the current panel section, tolerances and support system. Changes to surface relief may also affect edges, mass or interface coordination and therefore need formal review.
Where two textures meet, decide whether the transition aligns to a joint, uses a dedicated profile or occurs across separate facade zones. Draw the condition at a useful scale and include it in the mock-up if it is visually important. Avoid inventing the transition during installation.

Review water paths, deposits and cleaning
Texture can retain shadows, water or deposits differently across peaks, valleys and horizontal features. Coordinate copings, sills, drips, flashings and drainage routes through the complete facade design. Avoid relying on a dark color or deep groove to hide uncontrolled run-off.
Request current handling, protection, cleaning and maintenance information for the exact surface. Test a proposed cleaning method on a noncritical production-representative sample. Evaluate whether access and inspection remain practical at textured corners, soffits or high-level zones.
Approve representative samples and mock-ups
Move from small direction pieces to full-size samples and, where appropriate, a larger mock-up with actual joints, orientation and adjacent materials. Include representative limits for geometry, color, sheen and acceptable production variation, not only one ideal panel.
Tag approvals with product, surface, profile, batch, orientation and date. Define who accepts the range and how observations are recorded. A screen image or unlabelled sample should not control production after its identity and viewing context have been lost.
Control production range and batch QA
Specify current drawings, texture geometry, surface range, dimensional and visual inspection, sampling, part identification, packaging and nonconformity control. Review early production against retained references, then keep batch and facade-zone traceability. Reassess changes to tool, process, profile or finish.
At handover, retain samples, approved deviations, zone records and cleaning guidance. Explore current terracotta panel options and project references for design context before exact surface and system verification.
Define how future replacements will be reviewed against the installed wall. Later production may need a new comparison because light, weathering and batch variation affect perceived texture and color. A matching surface name alone does not guarantee a visually identical repair.
