Evidence
The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:
.
Design requirements
Cemher Microne Microcement is suited to seamless interior and exterior applications across walls, floors, ceilings, wet areas, and benchtops in residential and commercial settings.
Available in a curated colour range; all top coats are pre-tinted by Cemher New Zealand. Custom colour matching is available.
System total thickness is 3–4mm - allow for this height allowance in floor build-ups.
Suitable for use with underfloor heating and over existing tiles using the Microdur Hybrid system. Wheeled furniture is suitable.
Do not use as a crack filler or to fill significant holes, gaps, or joins.
Expansion joints must be respected and not filled completely.
Sample boards are recommended prior to final colour selection, as tonal variation is natural to the system.

Installation requirements
Cemher Microne must be installed by a Cemher Certified Applicator in accordance with the Cemher Microne Technical Data Sheet.
Substrate must be clean, dry, stable, and free from contaminants, with moisture content below 5% and a minimum compressive strength of 25N/mm².
Minimum application temperature 10°C.
Substrates include plasterboard (Level 4 finish required), Hardies, fibre cement board, render, painted surfaces, MDF, concrete, tiles (Microdur Hybrid system), and celcrete.
In wet areas, a compliant waterproofing membrane must be applied prior to microcement and must meet NZ standards. Cemher is compatible with Ardex WPM002 system.
System components: Primer 100, Microne Base (two base coats), Microne Medium/Fine (two top coats), and Aquamax Pro sealer (walls) or Aquapur70 sealer (floors).
Sand between all coats using white/undyed sandpaper.
Allow minimum 7 days cure before use, water exposure, or foot traffic. Full hardness achieved at 30 days.
Maintenance requirements
Do not wet or clean the surface for 7 days post-installation.
Avoid cleaning products for the first 14 days. Clean routinely with water and a pH-neutral product using a damp cloth. A
void acid-based, ammonia, chlorine, bleach, or abrasive cleaners. Do not allow water, food, or chemicals to sit on the surface for more than one hour.
Do not place hot objects directly on microcement - use heat-resistant mats. Lift rather than drag furniture; use protective pads under furniture legs. Prevent exposure to grit and abrasive particles.
The protective sealer is subject to normal wear and requires periodic reapplication - estimated every 2–4 years depending on use. Resealing must be carried out by a Cemher Certified Applicator using only Cemher-branded sealers; use of other products will void the warranty.
Regularly inspect the surface to assess sealer condition.
Compliance with these requirements is necessary to maintain the Cemher 10-year manufacturer's warranty.
