Specifying Microcement in a New Build: What Gold Coast Architects Need to Know

Microcement is increasingly being specified at design stage rather than added as a renovation afterthought. The architects and interior designers producing the best residential work in South-East Queensland are building it into their documentation from the beginning.

Why Specification Stage Matters

When microcement is specified at design stage, the entire substrate system can be designed around it. The slab, the waterproofing, the substrate build-up, the floor level — all of these can be optimised for a microcement finish rather than retrofitted to accommodate one.

The most common failures in microcement installations happen when the product is added late in a project, over substrates that were not designed for it. Cracks telegraph through. Moisture issues emerge.

Specifying early eliminates most of these risks.

Substrate Requirements

Concrete slabs — the ideal substrate. A properly cured, level concrete slab with appropriate moisture readings provides the best foundation. Allow a minimum of 28 days cure time before application.

Moisture — the single most critical variable. Moisture readings must be within specification before application begins.

Coordination With the Builder

Floor level. Microcement adds 3–5mm to the floor height. Account for this in the slab level at thresholds, door frames, and transitions to other floor finishes.

Waterproofing. The waterproofing membrane must be compatible with the microcement system. Specify both together.

Sequencing. Microcement is applied after all wet trades are complete and before painting.
