The Unitex Base Board lightweight cladding system is only half the equation — getting the render finish right is what delivers the weatherproofing, appearance, and warranty performance builders and specifiers rely on. Unitex has engineered a dedicated render build-up specifically for Base Board panels, rather than adapting a general-purpose render to fit.

The Base Board Render System

The system starts with patch and preparation work at sheet junctions, using Unitex Polymer Render with embedded Uni-mesh to reinforce joints and washer points before the main coat goes on — the step that prevents joint-line cracking as the building settles and moves. The base coat itself, Unitex Base Board Render (BBR 8.5), is then applied to a minimum 5mm thickness across the entire panel surface, creating a consistent, accredited base for whichever texture and finish coat the project calls for.

Built to Work With the Full Finish Range

Base Board Render is compatible with the full breadth of Unitex texture and finish options, including the Uni-Trowel Décor series, Uni-Roll Décor, Unitex Tanami, and Uni-Dry Cote Powder Texture, giving builders and designers genuine flexibility on the finished look without compromising the underlying system’s accreditation. It’s worth noting the system is not compatible with Uni-Rock or Unitex Veneto — a detail worth confirming with the technical sales team at specification stage if either of those finishes is being considered.

Why the Render System Matters as Much as the Panel

Base Board’s CodeMark, BRANZ, and BRAC accreditations apply to the complete system — panel, render, and finish together — not the panel in isolation. Using the specified Base Board Render and an approved finish is what keeps a project within its deemed-to-satisfy compliance pathway, and what keeps the 7-year system warranty intact. It’s also what delivers the thermal performance Base Board is chosen for in the first place: the render build-up is designed to protect the EPS core without compromising the R-value that makes Base Board approximately 400% more energy efficient than equivalent-cost rendered brick veneer.

Australian-Made, Consistent From Panel to Finish

Base Board Render is manufactured at the same Dandenong facility as the panels it’s designed for, meaning the whole system — substrate, render, and finish — comes from a single Australian production line with over 40 years of manufacturing history behind it. That consistency matters on-site: there’s no guesswork matching a third-party render to a proprietary panel system, and no compatibility risk to manage.
