Microcement over tiles can be a great option when renovating a bathroom, kitchen, floor or other tiled areas.
One of the questions we hear regularly at House of Render is:
Can microcement go over tiles?
In many situations, microcement can be installed over existing tiles, provided the substrate is suitable and the correct preparation and application system is used.
For homeowners renovating across the Sunshine Coast and Noosa, this can be an effective way to transform an existing tiled surface into a seamless, contemporary finish without necessarily removing every tile.
Can Microcement Be Applied Over Existing Tiles?
Yes, microcement can be installed over tiles in suitable situations.
However, the tiles cannot simply be cleaned and covered with microcement.
The existing surface needs to be properly assessed and prepared before the microcement system is installed.
The condition of the tiles, movement in the substrate, grout joints, moisture exposure and the particular microcement system being used all need to be considered.
This is particularly important for bathrooms, showers and other wet areas.
What Condition Do the Existing Tiles Need to Be In?
Before installing microcement over tiles, the existing substrate should be checked carefully.
The tiles should generally be:
- Firmly bonded
- Stable
- Free from significant movement
- Clean and free from contaminants
- Suitable for the proposed microcement system
Loose, cracked or unstable tiles may need to be repaired or removed before microcement is considered.
Microcement is a decorative finish. It shouldn’t be used to hide an underlying structural or substrate problem.
How Is Microcement Installed Over Tiles?
The exact installation process depends on the substrate and product system, but preparation is one of the most important parts of the project.
1. Inspect the Existing Tiles
The existing tiled surface is assessed to identify loose tiles, movement, cracks, damaged areas and other problems.
2. Prepare the Surface
The surface needs to be thoroughly cleaned and prepared so the subsequent system can bond correctly.
Grout lines, surface irregularities and other imperfections may require additional preparation.
3. Apply the Appropriate Primer or Base System
A suitable primer and base system is selected according to the substrate and the microcement manufacturer’s requirements.
4. Reinforcement Where Required
Depending on the substrate and system specification, reinforcement may be required to help manage the transition across the existing tiled surface.
5. Apply the Microcement
The microcement is applied in multiple stages to create the desired texture, movement and finish.
6. Seal the Finished Surface
Once the microcement system has been completed and cured appropriately, the correct protective sealer is applied.
The sealer is particularly important in areas exposed to water and everyday use.
Can Microcement Go Over Bathroom Tiles?
Microcement can be used over suitable existing bathroom tiles, including walls and floors.
It can create a continuous appearance across areas such as:
- Bathroom walls
- Bathroom floors
- Shower walls
- Shower areas
- Vanity areas
- Niches
- Feature surfaces
One of the major visual advantages is the reduction of traditional grout lines, creating a cleaner and more contemporary bathroom aesthetic.
Wet areas require particularly careful preparation, detailing and waterproofing considerations.
Can Microcement Go Over Floor Tiles?
Microcement can also be installed over suitable existing floor tiles.
This can be useful when renovating an existing home where removing the entire tiled floor would create unnecessary demolition, waste and disruption.
However, the existing floor needs to be suitable for the proposed system.
Floor movement, tile adhesion, existing levels and transitions around doors and other surfaces should all be considered before installation.
Why Choose Microcement Over Removing Tiles?
One of the attractions of microcement during renovations is that it can potentially be installed over an existing surface rather than requiring complete tile removal.
Depending on the project, this may mean:
- Less demolition
- Less mess
- Less waste
- Fewer disposal requirements
- Less disruption to the property
Every project is different, so an inspection is important before determining whether existing tiles can remain.
Does Microcement Crack Over Tiles?
The performance of a microcement system depends heavily on the condition and stability of the substrate and the installation system used.
If the existing substrate moves significantly, that movement can affect the finished surface.
This is why professional preparation is so important when applying microcement over tiles.
The objective isn’t simply to cover the tiles. The entire substrate and microcement system need to work together.
Is Microcement Over Tiles Waterproof?
Microcement should be considered as part of a complete system rather than simply a waterproof coating.
In wet areas, appropriate waterproofing, substrate preparation, detailing and sealing are critical.
The specific requirements will depend on the location, existing construction and products being used.
For bathrooms and showers, these considerations should be discussed with your installer before work begins.
How Thick Is Microcement Over Tiles?
Microcement is a relatively thin decorative finish compared with many traditional renovation options.
The overall build-up will depend on the particular system and preparation required for the existing tiles.
This can be an advantage when renovating because significant changes to floor levels may be avoided compared with installing a completely new floor system.
