Because of all these disadvantages, the scope of operation of cement-based grout is quite narrow. That is why manufacturers are developing other types of grout, such as in composition with polymers or based on epoxy resins.
Wet rooms must be treated with waterproofing materials, after drying of which decorative materials should be applied or laid, which are also not afraid of the influence of moisture.
If the grout darkens, turns yellow, is covered with spots, fungus or other unicellular animals – the general appearance of the decorative coating will be spoiled and unpleasant when used.
In terms of composition and performance characteristics, micro-concrete is very similar to high-quality decorative plaster, since it is also applied as a facing layer on a perfectly flat surface and serves for decades without requiring special care.
The best option both in terms of price and quality is polymer cement grout. It is she who is the favorite grout material among craftsmen who prefer to implement high-quality projects.
