Can Microcement Be Applied Over Tiles: The Science of Adhesion
One of the most common questions we hear as microcement installers is: “Can microcement be applied over tiles?” The answer is yes. Products like X-Bond are known as overlays; after some preparation work, overlays are installed directly over the top of your existing substrate to form a brand new surface covering. This makes it possible to refresh old materials without needing to demolish them. When it comes to X-Bond, the key to its long-lasting success in resurfacing tiles lies in the science of adhesion.
Why Microcement Is Perfect for Renovating Tiled Surfaces
Tiles are durable, but over time their grout lines, fragility (if ceramic), or dated finishes can make a space feel tired. Traditionally, replacing tiles meant ripping them up, disposing of rubble, and preparing the substrate from scratch. Microcement provides a smarter alternative.
Applied directly over existing tiles, a formula like X-Bond Microcement creates a seamless, durable new surface that works beautifully for internal and external floors, walls, or joinery — from the kitchen to bathrooms and even external areas. It’s also:
Cost-effective – no need to remove old tiles.
Time-saving & convenient – projects finish faster with less disruption.
Eco-friendly – avoids the waste of tearing out existing materials.
The Science of Adhesion: How X-Bond Sticks to Tiles
For microcement to perform well over tiles, adhesion is everything. To ensure a strong bond with tiled substrates, we need two things: correct preparation, and a formula built to last.
Surface Preparation: Tiles are first cleaned thoroughly to remove grease, dust, or sealants. This ensures the microcement layers can grip securely.
Levelling: Tiles are levelled to ensure a smooth, flat base — microcement itself is not a levelling compound (but can be built up or worked around slopes for drainage).
Waterproofing & Anti-Fracture: Often, tiles are in wet areas. We’ll apply a new liquid waterproofing membrane — with 2-in-1 anti-fracture protection — to ensure the new surface is resilient for years to come.
Molecular Bonding: The X-Bond Microcement formula involves additional polymer bonding agents which create an extremely strong bond to substrates. This is called Cross-Linking Technology — putting the ‘X’ in X-Bond!
This combination of chemical adhesion and meticulous surface preparation by trained, skilled professionals is what ensures a flawless, durable result.
Performance Benefits Of Microcement
When installed by experienced applicators like Alt. Surfaces, microcement delivers outstanding benefits, including:
Seamless Finish – a smooth, timeless surface that complements any design brief.
Durability – resistant to wear, scratches, and moisture/water.
Flexibility – microcement can be used indoors and outdoors, on floors, walls, or joinery.
Low Maintenance – easy to clean with no grout lines to trap dirt.
Can Any Tile Be Covered With Microcement?
In most cases, yes. Ceramic, porcelain, or even natural stone tiles can be resurfaced with microcement. The key factor is ensuring the tiles are solid and stable. If tiles are loose or damaged, these areas should be repaired before application.
So, can microcement be applied over tiles? Absolutely. With the right preparation and the proven science of adhesion, X-Bond transforms tiled surfaces into sleek, contemporary designs without the hassle of demolition.
