Clear answers start with the system.

Microcement is a hand-applied decorative surface finish installed as a layered system. A complete build can include substrate assessment and preparation, compatible primer, reinforcement where required, base coats, finishing coats and protective sealers. The correct build depends on the surface, its condition, the environment and the intended use.

These names are often used for related thin decorative coating systems, but they are not reliable product specifications. Formulation, layer sequence, preparation and protection can differ between manufacturers. Compare the complete documented system for the intended application rather than choosing by the label alone.

Microcement is a hand-applied coating system installed over a suitable prepared substrate. Polished concrete is the concrete surface itself, mechanically processed to create the finish. Microcement can be considered for walls and built forms as well as floors, while polished concrete is primarily associated with concrete slabs and floors.

Tiles are individual units separated by grout lines. Microcement is applied by hand to form a continuous decorative surface. It may sometimes be installed over stable existing tiles, but this depends on tile adhesion, joints, movement, moisture and the preparation system. It should not be selected simply to avoid assessing the existing surface.

The decorative coat is only one part of the finished surface. Preparation, primers, repairs, reinforcement, base coats, finishing coats and sealers each perform a different role. The required sequence changes with the substrate, wet or dry exposure, expected movement, traffic and finish, so one identical build is not suitable for every surface.

Microcement can create a continuous architectural finish across varied suitable surfaces and can reduce demolition in some renovations. It also allows control over colour, texture and protective finish. Its performance still depends on the substrate, preparation, application and sealer, and it cannot correct structural movement, active moisture or every unsuitable surface condition.

Potential applications include floors, walls, bathrooms, kitchens, feature walls, benchtops, stairs, ceilings, furniture and commercial interiors. Selected exterior surfaces may also be considered. Every application needs a system suited to its substrate, exposure, movement, wear and maintenance requirements.

Yes, where the substrate and selected system are suitable. Floors usually require more attention to stability, reinforcement, wear and protection. Walls and ceilings experience different loads but still require compatible preparation, particularly across joints, sheet substrates and existing coatings.

Microcement can be used as a decorative finish within an appropriately designed wet-area system. The compliant waterproofing, substrate, falls, junctions, penetrations, preparation products and protective sealer all need to work together. Microcement should not be treated as an automatic replacement for the required waterproofing system.

Microcement can be considered for suitable kitchen walls, splashback zones and built forms. The specification should account for water, heat, staining, cleaning and impact at the proposed location. Substrate preparation and sealer selection are part of that decision rather than separate finishing details.

It can be considered for suitable benchtops and vanities when the base is stable and the complete system is specified for the expected water, staining, heat, impact and cleaning conditions. These surfaces need application-specific preparation and protection rather than a standard wall build.

Microcement can be considered for suitable stairs, furniture and joinery. Edges, joints, movement, impact and the construction of the item need to be assessed before a system is selected. A decorative coating cannot make an unstable or flexible base suitable by itself.

It may be suitable when the substrate, expected traffic, cleaning regime and protective system are considered together. A commercial floor and a low-contact feature wall do not require the same build. SurfaceLab should review the application and use conditions before materials or project work are specified.

Selected exterior applications may be possible with an appropriate system. Exterior work needs additional assessment of water, UV exposure, temperature change, substrate movement, drainage, slip requirements and sealer selection. It should not be assumed that an interior wall system can be used unchanged outside.

It should not be applied without further work over unstable, loose, contaminated, persistently damp or unsuitable movement-prone surfaces. Product and build suitability also changes with permanent water contact, exterior exposure, heavy wear and specialist performance requirements. An assessment is needed when the substrate or use is uncertain.

It can be considered over tiles that are firmly bonded and form a stable substrate. The surface needs cleaning and compatible preparation, while joints, lippage, contamination, moisture and movement must be addressed. Loose tiles or a failed wet-area build cannot be corrected simply by coating over them.

Concrete and screed can be suitable substrates, but their condition varies. Strength, curing, smoothness, contamination, moisture, cracking and movement influence preparation. Rough or damaged concrete may need repair and levelling, while very smooth concrete may need a different bonding approach.

These constructed surfaces may be suitable when they are correctly installed, stable and prepared. Sheet joints, fixings, transitions, existing coatings and wet-area requirements need attention because movement or defects below the finish can remain visible or transfer through the coating.

Timber-based substrates may be considered for suitable joinery and built forms, but their movement, joints and construction require careful assessment. Natural timber and assemblies made from separate moving pieces can be unsuitable. Confirm the proposed substrate and preparation path before selecting products.

It may be applied over a suitable compliant membrane when the membrane and coating system are compatible. The membrane must be correctly installed and the surface needs the preparation required by the specified microcement system. Compatibility should be confirmed before the decorative work begins.

Not always. A stable and compatible existing surface may be retained after assessment and preparation, which can reduce demolition. Loose, weak, contaminated, moisture-affected or movement-prone finishes may need removal or corrective work before microcement can be considered.

A suitable substrate is generally sound, stable, dry, clean and appropriately level for the intended finish. Its porosity, existing coatings, joints, cracking, moisture and likely movement also matter. Assessment comes before selecting primers, reinforcement, base coats or finishing products.

Active dampness or an unresolved moisture source should be investigated before microcement is applied. Coating over the visible surface does not repair a failed membrane, leak or moisture problem below it. The cause must be resolved and the substrate assessed before the decorative system is specified.

Existing cracking needs assessment before coating. Repairs, compatible primers, reinforcement and base coats may form part of the preparation, depending on the cause and condition. If the substrate continues to move, that movement can transfer through a decorative finish despite careful preparation.

The approach depends on the substrate and the purpose of each joint. Structural or movement joints should not be hidden without assessment. Reinforcement mesh, repairs, primers and base coats may reduce risk in appropriate situations, but they do not remove structural movement or justify a no-cracking guarantee.

A decorative microcement finish should not automatically be described as a waterproofing membrane. The complete system and selected sealers can provide water resistance suited to particular uses, but wet-area compliance depends on the required waterproofing system beneath the decorative finish. Product-specific waterproof claims need supporting certification.

Yes. Where waterproofing is required, the wet-area build must meet the applicable National Construction Code requirements and use an appropriate compliant waterproofing system. Microcement is the decorative finish and should not be used to bypass waterproofing, drainage, junction or penetration requirements.

Microcement is not appropriately described as crack-proof. Cracks or movement in the substrate can transfer through a decorative finish. Assessment, repairs, reinforcement, compatible primers and the correct build may reduce risk, but broad no-cracking guarantees are not appropriate.

Durability depends on the complete system, substrate, application quality, expected wear, sealer and maintenance. A floor, benchtop and feature wall experience different conditions and should be specified accordingly. SurfaceLab does not apply one unsupported performance claim to every system or application.

Microcement should not be described as scratch-proof or stain-proof. The protective system can improve wear, stain resistance and cleanability, but performance varies with the sealer, use and maintenance. Spills, dragging objects, abrasive cleaning and concentrated wear can still affect a finished surface.

Colour, texture and sheen are shaped by pigments, hand application, sanding and the selected protective finish. The appropriate options also depend on the surface and expected use. Review current SurfaceLab samples and finish guidance rather than relying on screen colour alone.

An exact match should not be assumed. Microcement is mixed and applied by hand, so batch, technique, texture, scale, lighting and sealer can influence the final appearance. Samples are useful for agreeing on direction, but the completed surface will retain natural variation.

The applicator develops the surface through trowel movement, layer thickness, sanding and finishing technique. Light, scale and surrounding materials also affect how tone and movement are perceived. This variation is part of the material character rather than a printed repeat.

Use a soft cloth or mop and a cleaner compatible with the installed protective system. Remove spills promptly and avoid abrasive tools. Because care requirements can vary by sealer and application, follow the current care information supplied for the completed SurfaceLab system.

Advanced DIY customers and experienced trades may be able to apply suitable systems with the correct guidance, tools and preparation. Difficult substrates, floors, wet areas, exterior work and high-consequence applications require more technical judgement. DIY suitability should be assessed for the actual surface rather than assumed from the project size.

A typical process begins with substrate assessment and preparation, followed by compatible primer, repairs or reinforcement where required, base coats, sanding, finishing coats and the specified protective system. The exact sequence and number of layers depend on the substrate, environment and intended use.

Timing varies with area, substrate condition, repairs, wet-area coordination, layer sequence, drying conditions and project complexity. SurfaceLab reviews those details before giving a programme rather than publishing one standard duration for every project.

Material quantity depends on more than square metres. The application, environment, substrate, condition, preparation path, layer build and allowance for wastage all matter. Use the SurfaceLab Material Calculator for an initial plan, then confirm current product information and compatibility before purchase.

Cost is influenced by area, substrate condition, repairs, access, application type, wet or exterior exposure, detailing, finish and the required protective system. A square-metre rate without those details can be misleading. Share the project location, approximate area, substrate and current condition for a more useful assessment.
