Seamless surfaces, done properly

Microcement installation in Auckland costs between $280 and $550 per square metre depending on application type and project size. Floor installations range from $280/m² for large projects (100m²+) to $420/m² for small areas under 25m². Wet area walls and showers cost $350-$550/m². Prices include all materials, labour, and sealing. Minimum project charge is $3,500. All prices exclude GST.

Yes, microcement can be applied directly over existing tiles without demolition, provided the tiles are well-adhered and stable. The tile surface is prepared with a bonding primer, and the microcement system is applied over top. This makes microcement ideal for bathroom renovations where removing tiles would be disruptive and expensive. Loose, cracked, or hollow-sounding tiles must be repaired or removed before application.

Microcement is waterproof when installed with the correct system. A full wet-area installation includes a waterproof primer, fibreglass mesh reinforcement, a waterproof base coat, decorative topcoats, and dual sealers. This system is suitable for showers, wet rooms, and bathrooms. Basic wall systems without the full build-up are water-resistant but not fully waterproof.

Microcement floor installation takes 6-7 days minimum regardless of project size because each layer must dry before the next is applied. Wall installations take 4-7 days depending on the system. After installation, microcement requires a 7-14 day curing period before normal use. Light foot traffic is possible after 48 hours.

Microcement and polished concrete are different products. Polished concrete is existing concrete mechanically ground and polished to expose aggregate. It requires an existing concrete slab. Microcement is a thin 2-3mm coating applied over existing surfaces including concrete, tiles, plywood, and fibre-cement board without demolition. Microcement offers more colour options and can be applied anywhere.

Properly installed microcement with fibreglass mesh reinforcement is highly crack-resistant. The mesh distributes stress and prevents hairline cracks from substrate movement. However, if the substrate cracks significantly due to foundation settling or structural movement, the microcement may crack with it. Microcement follows the substrate—it is not structural.

Microcement floors require minimal maintenance. Sweep or vacuum to remove grit, then mop with pH-neutral cleaner and water. Avoid acidic cleaners, abrasive scrubbers, and bleach. High-traffic areas may need re-sealing every 2-5 years. Use furniture pads and entrance mats. With proper care, microcement floors last 15-25 years.
