Microcement and concrete-effect surfaces have become one of the most sought-after interior finishes — applied to walls, floors, worktops and bathroom surfaces to create a seamless, industrial-aesthetic finish. But these surfaces, despite their robust appearance, can crack, chip and develop damage that requires specialist repair. This guide covers professional repair for microcement and concrete-effect surface damage.
What Is Microcement?
Microcement (also sold as micro-screed, micro-concrete or mineral coating) is a thin coating — typically 2–3mm thick — applied over existing surfaces and sealed to create a seamless, contemporary look. It can be applied over tiles, concrete, wood and other substrates. The result is beautiful but requires proper application, sealing and ongoing care.
Common Microcement Damage
- Hairline cracking — common in areas of substrate movement, thermal expansion or inadequate preparation; fine cracks appear through the surface
- Impact chips — a hard impact creates a chip that penetrates through the coating
- Delamination — sections of the coating lifting from the substrate, usually indicating adhesion failure or moisture ingress
- Staining — microcement must be properly sealed; unsealed or inadequately sealed surfaces absorb oils and liquids easily
- Surface wearing in high traffic areas — the sealer layer wears, leading to dull patches or vulnerability to staining
Microcement Repair Challenges
Microcement repair is more challenging than standard surface repair because of the seamless, hand-applied nature of the material. Patches can be visible in a way that isn’t the case with standard surfaces. Successful repair requires matching the texture and colour of the surrounding material — both the base colour and the natural tonal variation that characterises microcement.
For delamination or widespread cracking, re-application of the affected section is often the correct approach rather than spot patching.
Get an Assessment
Microcement repair benefits from an in-person or thorough photo assessment before quoting. Send detailed photographs of the damage and the overall surface for an honest evaluation of what’s achievable.
