Column Capping Mouldings: Lightweight Rendered Column Capitals
The head of a column carries a lot of the visual weight of a verandah or portico feature, and getting that capital detail right on site — consistently, across several columns — is one of the harder parts of a masonry column build. Unitex column capping mouldings solve that with a lightweight EPS core and rendered finish, giving a factory-consistent capital profile that installs faster and matches the rest of the facade once rendered.
What is a column capping moulding?
Column capping is the capital, or head, component fitted at the top of a column shaft, providing the transition detail between the column and the beam, eave or entablature above it. It’s part of the Uni-Shape range of architectural profiles and columns, moulded from lightweight EPS and finished with a durable render coat to match the surrounding facade. Column capping is typically paired with a matching column base at the foot of the shaft, and can be fitted to a Unitex column or an existing column shaft, subject to compatibility.
Why builders and renderers choose lightweight column capping
A factory-moulded capital gives a consistent profile across every column on a job, without the variation that comes from forming each capital individually on site. Because the core is lightweight EPS rather than solid masonry, column capping is easier and safer to fit at height than a poured or built-up capital, and the rendered finish integrates directly with the base-coat and top-coat system already used across the facade. Where a column has a non-standard diameter or a project calls for a specific capital profile, custom sizing is available, supported by in-house CAD draftsmen and moulding specialists.
Application and substrates
Column capping is fitted at the head of a column shaft and finished with the same base-coat and top-coat system used across the broader Unitex range, so the capital reads as part of the same facade finish rather than a separate applied detail. As with the rest of the system, correct installation to the technical manual is required for warranty eligibility.
Column capping vs a complete column set
Where a project is starting from scratch — a new verandah or entry feature needing a full column — sourcing a complete Column Set, with base, shaft and capping supplied as a matched package, is usually simpler than specifying each component separately. A standalone column capping moulding suits projects repairing, replacing or matching the capital on an existing column where the shaft and base are already in place or already sourced.
Where column capping works well
Column capping suits verandah posts, portico columns and feature entry columns on both new builds and renovations, particularly where an existing column needs a capital repaired or replaced without redoing the whole column. It’s also a common specification on heritage-style renovations, where a period property’s original masonry capitals have weathered or cracked and a builder wants a matching replacement without the cost of a full masonry rebuild.
Backed by 40+ years of Australian manufacturing
Like the rest of the Uni-Shape range, column capping is designed with Australian conditions and construction practice in mind rather than adapted from an overseas catalogue. Column capping is manufactured as part of the wider Unitex range in Dandenong South, Victoria, drawing on more than 40 years of local render and moulding manufacturing experience. Since becoming part of the global Sto Group in 2019, Unitex has had access to international facade R&D alongside its own local development, and Technical Sales Representatives remain available to visit site and support correct specification and installation on individual jobs.
Common questions on column capping
Can column capping be custom-sized to fit an existing column?
Yes — where a standard capital doesn’t match an existing shaft diameter, the in-house CAD and moulding team can develop a custom profile.
Do I need to replace the whole column, or just the capping?
If the shaft and base are sound, column capping alone can usually be fitted or replaced without touching the rest of the column — worth confirming with a Technical Sales Representative for anything non-standard.
Will new capping match the existing render colour and texture?
Because it’s finished with the same base-coat and top-coat system as the rest of the facade, new column capping can be matched to the existing finish rather than reading as an obviously separate repair.

Column capping sits within the wider architectural mouldings and columns range, alongside column sets, column base and balusters — worth reviewing together on any project involving a full column feature.
