Q&A: Microcement Resurfacing
One of the most innovative things about microcement is its ability to be installed over existing materials. At SEMCO, we call this Remodel Without Removal, and it means you can resurface old substrates with a beautiful new microcement finish — without needing to demolish anything. SEMCO X-Bond Microcement can adhere to a wide range of substrates, including: tiles, concrete, MDF, bricks, stone, slate and more. In this guide, we answer questions related to resurfacing old materials with microcement.
What is Microcement?
Microcement is a decorative, cement-based surface coating made from a mix of cement, adhesive polymers, and color pigments. It’s applied by hand in thin layers (X-Bond is only 1/8” thick) to create a smooth, continuous surface with no joints — achieving the durability of concrete but providing a more lightweight, versatile, and customizable option.
Most microcement products can be applied directly over existing materials like concrete, tiles, plaster, self-leveling compound, and even MDF — making it ideal for resurfacing projects.
Where Can Microcement Be Used for Resurfacing?
Microcement is incredibly versatile and can be used to resurface floors, walls, ceilings, furniture, and joinery. This goes for both internal and external surfaces. And yes, you can even apply it in the bathroom and other wet areas, from kitchens to laundries and balconies.
Can Microcement Be Applied Over Tiles or Concrete?
Yes — and this is one of its biggest advantages.
Tile resurfacing with microcement avoids the need for demolition, saving time and hassle. This makes it a popular choice for luxury renovations where a quick and convenient construction process is desired.
Concrete resurfacing with microcement allows you to refresh old, worn, or damaged concrete surfaces without removing the base slab. Ripping up old concrete is quite a task. If there was an equally durable alternative that meant you could avoid demolition, why wouldn’t you choose it?
When Shouldn’t Microcement Be Used for Resurfacing?
Microcement has to be applied on a stable, hard, and level base. Before resurfacing, check the underlying substrate against this criteria. If the base surface isn't sound, microcement shouldn’t be installed just yet.
This doesn’t mean you won’t be able to use it all — we have plenty of case studies where X-Bond was installed over damaged or uneven substrates — but these issues must first be addressed. The good news is that there’s still no need to rip the old materials out.
How Durable is Microcement?
When professionally applied and sealed, microcement is:
Highly durable
Waterproofed
Stain and mold resistant
Impact resistant
Crack resistant (when applied over a stable substrate)
Low maintenance
It’s suitable for both residential and commercial applications and stands up well to everyday wear and tear.

Does Microcement Crack With Movement?
An overlay like microcement can crack if there’s significant movement in the underlying surface, especially if the substrate is unstable or poorly prepared. However, X-Bond is specifically engineered for flexibility — so it’s far more resistant to cracking than traditional coatings — and more so than any other formula on the market. Natural building movement won’t cause cracks in your X-Bond finish, even if you’ve installed it over an older material.
How does it work? X-Bond’s advanced polymer technology allows it to move with the substrate to a certain extent, reducing the risk of surface fractures caused by shifts or expansion. While no surface finish is completely immune to structural movement, choosing a flexible system like X-Bond and ensuring proper installation over a stable base will lead to longer lasting results.
Is Microcement Waterproof?
Yes — microcement is waterproof if a waterproofing membrane is installed as part of the application process. The sealer will also provide an added layer of protection against topical water damage such as mold and stains. This makes microcement a great renovation material for:
Wet areas like bathrooms and showers
Kitchen benchtops
Laundry surfaces
External areas exposed to rain
However, correct application is critical here, so choose a professional installer or a user-friendly DIY product.
What Colors and Finishes Are Available?
There’s so much design freedom with microcement. In our X-Bond range, there’s a wide range of standard colors — but we can also create custom shades. The visual finishes vary from solidly uniform to subtle tonal variation like a plaster, or a buffed and intensely dynamic appearance.
How Much Does Microcement Resurfacing Cost?
Costs vary based on the surface area, dimensions, complexity of the job, and condition of the substrate. An installer will give you the final quote based off the project plans. Compared to the cost of demolition and full replacements, resurfacing with microcement can be a more affordable and efficient solution compared to many other materials.
How Long Does Microcement Last?
With proper care, a microcement surface can last 10–15 years or more. Key to its longevity is:
Professional installation
Correct sealing
Regular cleaning with pH-neutral products
Avoiding harsh chemicals or abrasive tools
Is Microcement Suitable for DIY?
Microcement is a technical product, so if you’re opting for a DIY kit make sure you have:
Specialist tools
Skill in application
Substrate preparation and waterproofing knowledge
Understanding of drying times
Incorrect installation leads to issues like peeling, discoloration, or cracking. Previous experience working with plaster or rendering materials is therefore recommended.
