Render Systems for Clean Brickwork

Clean brickwork — brick free of deep raking, flaking paint, or significant surface imperfections — is the most straightforward substrate for acrylic rendering, and Unitex offers three compatible base coat systems so builders and renderers can match the right product to the project’s programme, budget, and compliance requirements.

Redi-Render: The Standard Choice

Unitex Redi-Render is the standard base coat for clean brickwork, applied directly to the surface by trowel in a single coat up to 10mm thick, without the need for a separate priming step. It’s a straightforward, reliable specification for the majority of clean brick projects, backed by the same 7-year warranty that applies across the Unitex system range and compatible with the full Unitex texture and finish range.

Fast-R Render: Built for Tight Programmes

Where mortar lines need eliminating and walls need levelling on a tight schedule, Unitex Fast-R Render offers the same direct-to-brick application with a faster build-up. It’s applied to the thickness required to level the wall and remove mortar joint lines in a single pass, with a second coat available if more than 10mm build is needed. For programme-driven projects, this is the system that keeps trades moving without waiting on extended cure times between coats.

Beach Render: Non-Combustible Performance

Unitex Beach Render is the non-combustible option in the clean brickwork range, formulated to AS 1530.1 standard for projects where non-combustible materials are specified — bushfire-prone builds, multi-residential developments, or any project where a building surveyor requires non-combustible certification for the external wall system. It applies the same way as the other two systems, by trowel, in coats up to 10mm.

Choosing the Right System for Your Project

All three systems share the same substrate compatibility and warranty terms, so the decision comes down to project priorities rather than substrate suitability. Redi-Render suits standard residential and light commercial projects with no unusual time pressure. Fast-R Render suits programme-critical builds where levelling speed matters. Beach Render suits any project where non-combustibility is a compliance requirement rather than a preference. Builders working across multiple brick substrates in one project — for example, an extension with both clean brickwork and AAC panel infill — can also confirm cross-substrate compatibility with the Unitex technical sales team to keep the finish consistent across the whole facade.

Why Brickwork Still Gets Rendered

Rendering clean brickwork remains one of the most common ways builders and homeowners update a facade’s appearance, improve weather resistance, or bring an older brick home in line with a contemporary streetscape — without the cost and disruption of full re-cladding. A well-specified acrylic render system also adds a layer of protection against moisture ingress at mortar joints, which is often the first point of weathering failure on unrendered brick walls.

Full Technical Specifications

Complete application detail for each system — coverage rates, coating thickness, and drying times — is available on the individual specification pages: Redi-Render Clean Brickwork, Fast-R Render Brickwork System Specification, and Beach Render System Specification.
