Microcement on tiles – an affordable way to renovate

We are increasingly looking for modern solutions that not only ensure functionality but are also a non-invasive alternative that allows for faster renovation of spaces. In this context, microcement is becoming an increasingly popular choice, especially when considering how to renovate a bathroom without removing ceramic tiles. Microcement not only avoids tedious renovation work, but also offers a number of other benefits that make it worth considering for use on existing tiles.

MICROCEMENT ON TRADITIONAL TILES WITHOUT REMOVAL

Bathrooms often feature unusual solutions that reflect a modern approach to interior design. Instead of classic ceramic tiles, materials such as microcement, architectural concrete, and natural stone are becoming increasingly popular. These alternative finishes allow you to create a unique aesthetic that perfectly reflects the personal preferences and style of the owner. A space without traditional tiles not only provides a unique look, but also makes it easier to keep clean by eliminating the problem of dirty grout that requires frequent cleaning. In addition, the Festfloor microcement system offers exceptional moisture resistance, which is crucial in areas exposed to water, such as showers or washbasins. One of the main advantages of microcement is that it can be applied to tiles without the need to remove them.

Is it possible to renovate a bathroom without removing tiles?

Yes, bathroom renovation without removing tiles is possible thanks to the use of Festfloor microcement, or more specifically, HydroFest microcement. It can be applied to existing ceramic tiles, but the process requires careful preparation of the substrate to ensure the durability of the microcement coating. Microcement is only a decorative layer, so it is necessary to properly prepare the substrate to create a cohesive and durable surface with this type of finish, and to ensure that the joints are not visible. Another condition for the use of microcement is that the tiles must be in good condition and firmly adhered to the substrate.

How to apply HYDROFEST microcement on tiles step by step?

BATHROOM RENOVATION WITHOUT REMOVING TILES

Covering ceramic tiles with HydroFest microcement requires careful preparation of the surface to ensure the durability of the new finish. Below, we describe all the steps you need to take to properly apply microcement to tiles.
However, remember that in order to apply microcement to ceramic tiles, they must adhere firmly to the substrate, as the stability of the tiles is crucial for the durability of the entire structure. Therefore, before applying microcement, check carefully that they are well attached to the substrate.

SILICONE REMOVAL, TILE MATTING AND GROUT FILLING

If the ceramic tile substrate is stable, the first step is to remove old silicone, which can weaken the adhesion of subsequent finishing layers, leading to durability problems in the long term.

The next step is to matt the tiles using an orbital sander. This process allows for better adhesion of subsequent layers of material.

After matting the tiles, the next step is to fill the joints between the tiles. For this purpose, you can use a filling compound. This process involves applying the compound or mortar along the gaps between the tiles, which allows them to be filled solidly. Proper filling of the joints is important not only for aesthetic reasons, but also for functional reasons, as it ensures the tightness and durability of the entire surface.

PRIMING

Before strengthening the substrate and applying microcement, it is necessary to prime the surface. For this purpose, use our FestGrunt product, which evens out absorbency and improves the adhesion of subsequent layers. The surface must be perfectly hardened, dry, and clean. Apply FestGrunt with a roller or brush. On uneven or very absorbent surfaces, it is recommended to apply the product in several layers. Leave to dry for 2-4 hours. After this time, you can proceed to reinforce the substrate. Read the product data sheet before use.
Priming is a key step in preparing the surface before applying finishing materials, ensuring better adhesion and durability of the entire structure.

SUBSTRATE REINFORCEMENT

Proper reinforcement of the surface before applying microcement is crucial to prevent possible cracks (if the stability of the substrate is not guaranteed). This ensures the durability of the entire structure, which is important for the long-term effect. When applying microcement to ceramic tiles, it is essential to reinforce the substrate with the following products:
- on walls, use FEST KONTAKT bonding bridge with fiberglass mesh.
- on floors, use FESTFLOOR Base with mesh.
These products are also available in kits, here. Read the technical data sheets before use. After the primer coat has dried, sand and vacuum the surface.

MICROCEMENT APPLICATION

The next step is to apply HydroFest microcement, designed for wet areas. Spread the mixture over the entire surface using a trowel to a thickness of no more than 1 mm. Apply quickly and vigorously in different directions, adjusting to achieve the desired effect.
After about 4 hours, when the material has completely set and dried, it is recommended to sand the surface with an eccentric sander with 60-120 grit sandpaper. Then, thoroughly vacuum the surface and continue applying the second layer of microcement, following the same procedure as for the first layer.
After the second coat has dried, it is recommended to sand the surface again and vacuum the dust. Once these steps have been completed, you can proceed with the impregnation of the microcement.

MICROCEMENT IMPREGNATION

The next step is to protect the microcement. Especially in areas prone to contact with water, such as bathrooms, it is recommended to use a primer such as FESTPRIMER, which strengthens the resistance of the varnish to water and dirt.
Once FestPrimer has dried, you can proceed with applying the sealer. For shower floors and floors throughout the bathroom, we recommend using PU FEST TURBO solvent-based varnish with the addition of Nano Silver Plus SB, which contains silver nanoparticles for additional protection against microorganisms. For walls, however, it is sufficient to apply two coats of PU FEST 2K varnish with the addition of Nano Silver Plus WB, which has antibacterial and antifungal properties. 
Protecting microcement with varnish not only protects it from moisture, but also extends its durability. It is best to use a high-quality microfiber roller to apply the varnish.

How to care for microcement?

MAINTAINING THE CLEANLINESS OF MICROCEMENT SURFACES
Regular care is essential to maintain the long-lasting aesthetics and functionality of microcement surfaces in the bathroom. As with other surfaces, regular dry vacuuming is sufficient to keep microcement clean. However, given the specific nature of microcement in the bathroom, we recommend using our specialized care products:
♦ FEST CALC – an excellent product for removing soap, limescale and water deposits. Suitable for microcement surfaces as well as tiles and fittings. Restores shine and gloss to dirty surfaces.
♦ FESTCLEANER – effectively removes dirt and all stains, leaving the microcement surface clean and refreshed. Thanks to its polyurethane micro-particles, it strengthens the protective layer of microcement. In addition, it has a natural scent and is safe for health.
♦ POWER-FEST – an intensive cleaner for removing stubborn dirt, such as grease stains or deposits from cleaning products. Its powerful formula guarantees effective removal of stubborn dirt while refreshing the microcement surface.
