Applying microcement over existing tile is an excellent way to get a seamless, modern finish without the hassle of demolition. The entire process—which typically takes about 3 to 5 days—involves filling grout lines, applying a high-adhesion primer, embedding a fiberglass mesh, troweling multiple microcement coats, and sealing.
Yes, you can absolutely microcement over existing tiles. It is an excellent, modern renovation option that saves you the cost, mess, and time of demolition. Because microcement is only about 222 to 3 mm thick, it transforms the space without significantly altering floor heights or door clearances.
The main benefit of microcement is its excellent adhesion and compatibility with all types of materials, including tiles which is the topic we are dealing with today. In this way, the microcement is applied directly onto the tiles without the need to remove them.
While microcement provides a beautiful, seamless finish, its main problems stem from delamination, cracking, staining, and wear. These issues are almost always caused by improper surface preparation, moisture trapping, or DIY-level application mistakes rather than the material itself.
Yes, you can DIY microcement. It can be applied to walls, floors, countertops, and even directly over existing tile. However, it is not a forgiving or fast project. It requires significant patience, strict adherence to drying times, and multiple sanding and sealing coats.
3️⃣ Prone to Cracks Over Time – If the substrate moves or flexes, micro cement can develop hairline cracks. 4️⃣ Requires Proper Sealing – If not sealed correctly, it can absorb water, stain, and wear faster. 5️⃣ Longer Installation Time – Multiple layers and curing time mean your bathroom renovation can be lengthly.
Coca-Cola does three main things to concrete: it slows down the curing process (acts as a retarder), etches the surface to expose decorative aggregate, and removes tough stains. This happens because of the soda's high sugar content and phosphoric acid.
When professionally installed and maintained, microcement typically lasts 10 to 20 years, with some surfaces enduring even longer. Its longevity largely depends on proper sealing and avoiding abrasive wear.
Forget about the trowel for applying ready-to-use microcement! You'll only need it to smooth the layers once applied. Both the two coats of Smart Base and the two coats of Smart Liso can be applied easily using a polyamide roller.
Covering old tiles without removing them saves immense time and mess. For a quick and affordable fix, opt for peel-and-stick vinyl or tile decals. For durable, high-end upgrades, install new tile over the top, pour micro-cement, or use specialized tile paint.
Preparing Floor Tiles for Microcement
Covering floor tiles cheaply is entirely doable without the mess and expense of demolition. The most budget-friendly and durable DIY methods include painting with tile-specific floor paint, applying peel-and-stick vinyl planks or tiles, or simply covering the space with a large, stylish area rug.
Like tiles, concrete, or polished stone, microcement can become more slippery when wet — particularly if the surface is very smooth. For wet areas, slip resistance is managed by: Controlling the final surface texture. Choosing the appropriate sealer finish.
Hiding tiling mistakes depends on the type of error. Here is a quick breakdown of the most common issues and how to disguise or fix them:
You can easily change the look or function of existing tiles without the mess of demolition. Depending on your needs, you can paint over them, apply peel-and-stick covers, resurface them, or float new rigid flooring directly on top of the old tiles.
You can cover old or dated tiles without the mess of demolition by using methods like PVC wall panels, specialist tile paint, or peel-and-stick vinyl. For the best results, ensure your current tiles are structurally sound, flat, and thoroughly cleaned with a degreaser before starting.
While microcement offers a sleek, seamless finish and modern aesthetic, it comes with several notable disadvantages. The most significant drawbacks include high costs, strict reliance on highly skilled labor, the risk of cracking, and tedious maintenance requirements.
Advantages of Applying Microcement on Tiles
Unlike many other coverings, microcement can be applied directly onto existing tiles, eliminating the need for costly and time-consuming removal work. This not only saves time but also minimizes inconvenience for homeowners and neighbors.
Top Substrates for Microcement
Microcement is generally very good at resisting mould, because there's no grout lines, so there's not a lot of opportunity for it to take hold. Regular cleaning should prevent mould from appearing & keep it under control if it does.
Microconcrete contains cement, aggregates, and additives to enhance its strength and workability. Unlike microcement, which is applied as a thin layer, microconcrete is poured or sprayed at a thicker consistency, allowing it to be used in areas that require higher structural integrity.
To prolong the lifespan of your microcement, we recommend resealing every two to three years, depending on usage and foot traffic, to help maintain water resistance, stain protection, and overall durability.
Water is the most common enemy of concrete surfaces. When water penetrates the surface of concrete, it can cause it to crack and weaken. This is especially true in colder climates where water can freeze and expand, creating even more damage.
Yes, Dawn dish soap is excellent for cleaning concrete and is highly effective at breaking down grease and oil. Mix 14one-fourth14 cup of Dawn with a gallon of warm or hot water, apply it to the concrete, scrub with a stiff bristle brush, and rinse thoroughly.
The 90-minute rule is a longstanding concrete industry guideline stating that ready-mixed concrete should be completely discharged from the mixing truck within 90 minutes from the time water is first added to the cement. This limit ensures the mixture remains workable and achieves its full structural strength.
