Microcement flooring is increasingly specified for residential and commercial interiors, offering an alternative to traditional flooring materials such as tiles, timber, stone slabs, and polished concrete.
But while the aesthetic appeal is easy to understand, there are plenty of practical considerations when choosing microcement for floors. How does it perform under heavy foot traffic? Can it be applied over existing flooring? Does it scratch, stain, or become slippery when wet?
At SEMCO, we receive questions about these applications regularly. In this guide, we're answering some of the most common questions about X-Bond Microcement flooring, from substrate preparation and durability to maintenance and long-term performance.

1. Is Microcement Durable Enough for High-Traffic Flooring?
Yes. When correctly installed and maintained, X-Bond Microcement is suitable for a range of high-traffic residential and commercial flooring applications — including both interior and exterior floor applications.
Unlike a conventional decorative wall coating, for a microcement system to be suitable for flooring it needs to withstand repeated foot traffic, furniture movement, cleaning, and general wear.
X-Bond is a polymer-modified cementitious overlay designed to create a durable surface at approximately 1/8 inch thick. Despite its thinness, its advanced molecular formulation provides the strength, flexibility, and adhesion required to withstand high levels of use.

2. Can Microcement Be Applied Over Existing Flooring?
One of the advantages of X-Bond is the ability to remodel without removal, with compatibility over a wide range of existing substrates. This allows flooring renovations to be completed without demolishing the original surface.
Depending on the condition of the substrate, X-Bond can be applied over materials including:
Concrete
Existing ceramic and porcelain tiles
Stone slabs
Suitable cementitious flooring
Some existing coatings e.g. epoxy — provided compatibility and adhesion requirements are met
However, substrate compatibility doesn't mean every existing floor is immediately suitable for resurfacing. The existing surface needs to provide a hard, level and stable base for the new microcement system.
Loose tiles, deteriorating coatings, and underlying moisture issues must be addressed before application. Floorboards, timber, and vinyl flooring are also generally unsuitable for direct application, as they can flex, shift, or expand significantly underneath the microcement.
3. Will Grout Lines Show Through Microcement Flooring?
Grout joints create variations in the substrate’s surface level. If this isn’t properly addressed, it can affect the consistency of the finished microcement application, as it needs to be applied in uniform layers.
Before microcement is applied over existing tiles, grout lines need to be properly filled and levelled first to create an even base. Preparation generally involves filling grout joints and levelling the uneven areas with base coats and/or mesh coats.
The condition of the tiles themselves is equally important. Any loose, hollow, or poorly bonded tiles should be repaired or removed rather than simply covered.

4. Does Microcement Flooring Scratch Easily?
Like most flooring materials, microcement can be scratched under certain conditions.
X-Bond is designed to provide a durable surface, but it isn't completely scratch-proof. Abrasive particles, dragging heavy furniture, and repeated contact with sharp objects can damage the protective finish.
Simple precautions such as using furniture pads, removing abrasive dirt, and avoiding dragging heavy objects can help preserve the finish.
5. Does Microcement Flooring Stain?
Properly sealed microcement offers resistance to everyday spills, but no flooring surface should be considered completely stain-proof.
Because microcement is a cementitious material, the protective sealer is particularly important in limiting the absorption of liquids and contaminants. X-Bond flooring is finished with a suitable SEMCO sealer selected according to the intended application.
For areas such as kitchens, hospitality venues, and commercial interiors where spills are more likely, selecting the appropriate sealer and maintaining it correctly are essential. Spills should still be cleaned promptly, particularly substances such as oils, wine, coffee, and acidic liquids.
On exterior applications, X-Bond flooring is resistant to both UV degradation and weather, so it won’t fade or stain when exposed to sunlight, rain, and other environmental conditions.

6. Is Microcement Flooring Slippery When Wet?
X-Bond is suitable for slip resistant microcement flooring throughout wet areas including bathrooms and pool surrounds. However, the slip resistance of microcement flooring depends on the surface texture and overall finishing system specified.
SEMCO also offers ADA Safety Floor, a slip-resistant treatment designed to improve traction on suitable flooring surfaces.
7. Can Microcement Be Installed Over Heated Floors?
Yes. X-Bond can be used over underfloor heating systems. Its cementitious composition makes it compatible with the temperatures typically associated with underfloor heating, while X-Bond's polymer-modified formulation provides flexibility to help accommodate minor thermal movement.
8. Can Microcement Be Applied Over Cracked Concrete Floors?
This depends on the cause, severity, and activity of the cracking. Concrete floors can develop cracks for several reasons, including shrinkage during curing, settlement, structural movement, and changes in temperature.
Some non-moving cracks may be suitable for repair and resurfacing with our X-Bond system, while active cracks require further assessment.
Microcement should not be relied upon to stabilise a moving concrete slab or prevent ongoing structural cracks from transferring through the finished surface.
Before applying X-Bond, contractors should establish whether cracks are dormant or active, determine the appropriate repair method, and assess whether crack-isolation measures are required.
Existing control and expansion joints must also be considered. These joints serve an important function in accommodating movement and should not simply be concealed beneath a continuous overlay.

9. How Thick Is Microcement Flooring?
X-Bond Microcement is typically installed at approximately 1/8 inch thick. This makes it considerably thinner than many conventional flooring systems, which can be particularly advantageous during renovations.
For example, resurfacing existing floors with a thin overlay may reduce the need for extensive changes to door clearances, thresholds, and adjoining floor levels.
However, X-Bond is not a self-levelling product. If an existing floor has significant variations in height, uneven areas, or drainage issues, these need to be addressed using appropriate preparation methods before applying the microcement system.

10. Is Microcement Flooring Waterproof?
X-Bond can form part of a waterproof flooring system when installed in conjunction with SEMCO Liquid Membrane. In wet areas such as bathrooms and showers, SEMCO Liquid Membrane is incorporated beneath X-Bond as the specified waterproofing assembly.
It's important to distinguish between the decorative microcement finish, its protective sealer, and the waterproofing membrane beneath it.
A sealer helps protect the surface against everyday moisture exposure and staining, but it should not be treated as a replacement for a dedicated waterproofing system where one is required.

11. How Do You Clean and Maintain Microcement Floors?
Microcement flooring is relatively straightforward to maintain. Regular maintenance generally involves:
Sweeping to remove dirt and grit
Cleaning with a soft mop and a suitable pH-neutral cleaner
Hosing external floors
Avoiding harsh chemicals and abrasive cleaning products
Wiping up spills promptly
Using protective pads beneath furniture
Commercial floors generally experience greater wear than residential interiors, so maintenance requirements should be considered during the specification stage.

Specifying X-Bond for Flooring Applications
X-Bond Microcement offers a combination of design flexibility and practical performance that makes it suitable for a wide range of flooring projects.
Its thin application profile, compatibility with many existing substrates, and seamless finish make it particularly useful where traditional flooring materials may introduce additional height, visible joints, or more extensive renovation work.
However, the performance of any microcement floor depends on the complete installation system. Things like substrate preparation, waterproofing where required, and sealer selection all play important roles in achieving a durable result.
For contractors and designers considering X-Bond for an upcoming flooring project, contact SEMCO Surfaces for product information and guidance on the appropriate installation system.
