Microcement
Renovation
Can microcement cover existing tiles? In some projects, yes—but the answer starts with the condition of the base. Stable, compatible surfaces may be prepared for overlay. Loose or hollow tiles, unresolved moisture, cracks or movement may require repair, partial removal or a different substrate approach.
Begin With
What Is
Underneath.
Renovation begins with a question: what can stay, and what needs to change?
Existing homes rarely begin with a blank substrate. Tiles may be stable or hollow. Cracks may be superficial or associated with movement. Previous finishes may be suitable, weak or incompatible.
Microcement therefore begins with assessment rather than appearance. The existing base informs the preparation route, detailing and final surface system.
What May
Remain?
Selected existing surfaces may sometimes remain in place. Suitability depends on condition, stability, compatibility and the preparation required for the intended application.
Stable Existing Tiles
Properly bonded tiles may sometimes form part of the renovation substrate after site assessment and suitable preparation.
Screed or Mineral Base
Existing cementitious substrates may be considered when sufficiently stable, cured and appropriate for preparation.
Existing Wall Finishes
Previous coatings require assessment for adhesion, compatibility and stability before a new decorative system is introduced.
Not Every
Surface Should
Be Covered.
Overlay is a project decision rather than an automatic rule. The condition underneath should be understood before decorative application begins.
Inspect
Review tile adhesion, cracks, movement, transitions, moisture and general surface condition.
Determine Stability
Identify whether the existing surface can form part of a suitable working substrate.
If Suitable — Prepare
Proceed through the required preparation, reinforcement and specified microcement system.
If Unsuitable — Repair or Remove
Unstable or incompatible areas may require remedial work or removal before a suitable base is established.
Change the
Surface.
Keep the Space.
Renovation does not always need to begin with total visual demolition. Where existing conditions allow, a new surface system can transform the character of an interior while retaining much of its existing architectural framework.
Different
Surfaces.
Different Decisions.
Floors, bathrooms and walls share the same renovation principle, but each environment introduces different substrate, detailing and performance considerations.
Floors
Existing tiled or mineral floors may sometimes be retained when sufficiently stable and suitable for preparation.

Existing wet areas require additional consideration of substrate condition, waterproofing, junctions and protection.

Existing walls and selected finishes may be transformed subject to adhesion, stability and suitable preparation.

Selected stairs, niches, furniture and built forms may be considered according to their construction and substrate.
Renovation
in Practice.
Completed Semiforêt projects show how the renovation approach changes according to property type, existing condition, application area and intended finish.
Microcement,
Tiles or
Screed?
These materials solve different renovation needs. The decision should consider existing conditions, desired appearance, build-up and level of intervention rather than treating one material as universally superior.
Microcement
A thin decorative surface system chosen for a continuous mineral appearance over suitable prepared substrates.
Tiles
A modular surface solution with defined joints and established installation methods.
Cement Screed
A cementitious finish with a different build-up, construction method and visual character.
Surface Design
Needs Technical
Context.
Material performance should be read together with substrate preparation and application conditions.
Selected third-party laboratory reports for Semiforêt microcement are available through the Technical Evidence library, including hardness, compressive and flexural strength, VOC and formaldehyde, fire performance and other material testing.

Before You
Decide What
to Remove.
Before deciding what to retain or remove, prepare a floor plan if available, approximate dimensions, current wide-angle photos and close-ups of visible defects. Tell us which surfaces you want to change, your preferred finish, intended timing and occupancy constraints. Include any known history of leaks, repairs or surface treatments. Describe the project through the contact page and ask which channel to use for plans and photos. This helps define the assessment; it is not a confirmed overlay decision, quotation or construction date.
