How long does microcement take to install?

How long does microcement take? For most projects, the application process typically takes 5 to 7 days, depending on the size and complexity of the work. That covers surface preparation, the microcement layers themselves and final sealing.

It can seem a long time for a finish only 2–3 mm thick, but the time is not spent building thickness. It is spent preparing the surface, letting each layer dry and applying the next one in the right order. This guide sets out the sequence, what can extend it and how to plan the rest of your project around it.

Why microcement takes days, not hours

Microcement is applied by hand in thin layers, and every layer has to dry before the next one goes on. Between coats, surfaces are sanded to remove irregularities, and the sealer may need several coats of its own. Each pause is part of what gives the finish its bond and durability.

Rushing any of these steps is a false economy. A layer applied over one that is still damp, or over a surface that has not been properly prepared, can compromise adhesion and the quality of the finish. Our process page explains each phase in more depth.

An indicative microcement timeline

The table below maps the application steps to an indicative sequence. It is a guide, not a guaranteed schedule: the actual timing for your project is confirmed after the substrate has been assessed and depends on the surfaces, the conditions on site and how the work is staged.

Drying versus curing

Drying and curing are easy to confuse. A layer is dry when it is ready for the next step of the process, while curing is the longer period in which the whole system continues to harden and gain full strength. Microcement keeps hardening for several weeks after application, even though the work itself is finished.

For planning, it helps to treat the first week after completion as part of the program rather than time after it.

• Book furniture deliveries and move-in dates with the first week in mind, so heavy pieces are not rushed in.
• Where possible, avoid scheduling other trades to work on or across new surfaces during that week.
• Allow for light use only in the finished rooms, with felt pads on anything that does return.
• On heated floors, plan when the heating comes back on using the advice given at handover.

What can extend a microcement project

The 5 to 7 day range covers most projects, but several factors can lengthen the program.

• Size. Larger areas take longer at every stage, and very large floors may need to be completed in sections.
• Complexity. Stairs, curved walls, niches, benchtops and furniture involve more edges and detailing than open walls and floors. Our page on microcement stairs shows one example.
• Substrate repairs. Loose tiles, cracks, uneven surfaces or excess moisture need to be addressed before application, since the substrate must be stable, level and below 5% humidity.
• Temperature and humidity. Cold, damp or very humid conditions can slow drying between layers.
• Multiple rooms. Several rooms, or walls and floors in the same space, may need to be sequenced so each area can be reached and left to dry in turn.
• Access. Tight access, other trades on site or rooms that must stay in use can all add time.
• Underfloor heating. New heated floors follow a specific protocol, including turning the heating on at least four weeks after laying the base layer and switching it off at least 48 hours before installation. Our underfloor heating guide has the details.

How to plan around microcement

Sequencing other trades

Microcement generally goes on once demolition, dusty work and services rough-in are complete. Fixtures that need to be removed or reinstalled, such as toilets, vanities, tapware and skirting, should be coordinated with your builder or plumber so they come off before the work starts and go back once the surface is ready.

Access and protection

The areas being worked on need to be clear and closed off until application is complete. If the project includes your only bathroom, main entry or a thoroughfare, plan an alternative route or facility before the start date, and keep pets out of the work zone. If you are living in the home during the works, ask where materials and equipment will be staged and how sanding dust will be contained.

Furniture and belongings

Clear the rooms completely before the start date, including anything stored in built-in cupboards that open onto the work area. Decide in advance where furniture will go and when it will come back, allowing for the first week of care.

Microcement compared with a full renovation

Microcement can be applied directly to many suitable existing surfaces, including tiles that are firmly adhered and stable, so it can avoid the demolition, rubble and waiting that come with a strip-out. Application is generally quicker and less disruptive than many traditional renovations. Our guides to microcement over tiles and microcement vs tiles compare the options.

Remember that the 5 to 7 days refers to the microcement application. If your project also includes plumbing changes, waterproofing, joinery or electrical work, those trades add their own time on either side.
