Is the microcement suitable for use in the shower? Is microcement waterproof? Can it be used in the bathroom? How to prepare the substrate? – these are the most frequently asked questions by our customers.

The answer is yes, Festfloor microcement can be used in the shower, in the bathtub or washbasin area.

 

How to prepare the substrate for microcement in the shower?

Preparation of the substrate in wet zones is extremely important and does not differ much from the preparation of the substrate for other finishing materials, e.g. tiles. As a standard, we recommend the use of system waterproofing: waterproof tapes on walls joints and wall/floor joints as well as e.g. liquid foil on the entire surface.

When applying microcement to existing tiles, it is not necessary to reapply waterproofing. In turn, the tiles should be polished, the joints should be filled to make the surface even and a primer and a bonding bridge with fiberglass mesh should be used. After bonding bridge has cured, we can proceed to apply the microcement in two layers, grind and then protect the surface. For this purpose, we recommend using the FEST Primer undercoat. It is not a mandatory product, but it increases resistance to water and dirt, and reduces sealer consumption. Then the only thing left is to apply two layers of PU FEST 2K sealer included in the kit.

The shower can be fully used after 7 days from applying the sealer. After this time, the varnish is fully hardened and provides adequate protection against moisture and dirt.

Microcement in the shower: Can I make a microcement floor on a walk-in shower base?

Observing interior design trends, there is a clear tendency to move away from traditional shower trays and replace them with walk-in showers with a linear drain. They are often finished with microcement. After installing the drain, introducing the appropriate slope – most often with a cement screed – system waterproofing should be applied as described above. The most common are waterproofing tapes around the drain line, as well as at the wall/floor joints, and a liquid foil or other liquid waterproofing over the entire surface.

Replacing plastic shower bases with a microcement finish makes the bathroom much more hygienic and easier to maintain. This solution gives the place a uniform character and can visually enlarge a small bathroom, especially when we use a concrete total look, i.e. microcement on the floor and walls.

It is also important that the microcement is pleasant to bare feet and underfloor heating can be used underneath.

 

How to finish the wall/floor joint?

Due to the fact that the connection between walls and the floor is most often secured with a waterproofing tape, it is not necessary to transfer the dilatation joint to the microcement. The tapes will transfer the stresses resulting from building movements and  you can be sure that no cracks will appear in this area.
