What is microcement?

What this means for your home project

1. CimentArt says "It is also not recommended to apply the microcement system with strong direct sunlight or strong air currents, as this will accelerate its drying time too much and hinder its application." (read 2026-11-04). (source)
2. Topciment says "We must avoid leaving wet rugs and towels on the floor or pots that lose liquid." (read 2026-11-04). (source)
3. Topciment says "To move furniture: better to lift and support, never drag." (read 2026-11-04). (source)
4. Topciment says "It will be necessary to protect the pavement from furniture (metal legs, sharp surfaces), and from objects with abrasive or considerably heavy contact surfaces, with caps or felts." (read 2026-11-04). (source)

What is the resistance and hardness of the microcement?

Topciment says (read 2026-11-04): “Thus, products with coarser granulometries, such as Sttandard Microbase (L, XL, XXL), are recommended for floors.” (source) “For walls, on the other hand, products with finer granulometries, such as Sttandard Microfino (S, M), are suitable.” (source) “Impact resistance is studied under the standard UNE-EN ISO 6272-1:2012: Falling mass test with a large-surface striker.” (source) “This test analyzes in a standardized way how microcement deforms when it receives a blow.” (source)

On what supports can microcement be applied?

Topciment says (read 2026-11-04): “Microcement can be applied on almost any type of support: cement mortar, self-leveling, terrazzo, marble, tile, plasterboard or plaster.” (source) “Indeed, microcement cannot be applied on natural wood or supports made up of pieces that may dilate differently.” (source)

Is microcement waterproof?

Topciment says (read 2026-11-04): “Other types of microcement, while not waterproof on their own, can attain this quality through the application of a dedicated sealing varnish.” (source)

What are the differences between microcement and polished concrete?

Topciment says (read 2026-11-04): “This is a coating that is worked with a prior conditioning of the surface, an application of the material in different layers, and a final protection with sealer.” (source) “Polished concrete: On the other hand, polished concrete involves applying a surface treatment to achieve the final finish but on fully cured concrete.” (source)

How long should we let the first coat of microcement sealer dry before applying the second one?

Topciment says (read 2026-11-04): “The drying time between layers of the sealer or varnish will depend on several factors.” (source) “In any case, we will always try under any circumstances to leave the maximum drying time possible between layers to avoid the formation of white spots due to the surface still being wet.” (source) “The minimum drying time between layers is 4 hours for the Presealer and 24 hours for the Topsealer.” (source)

How should you clean the microcement?

Topciment says (read 2026-11-04): “Although microcement offers high resistance to chemical products, the cleaning of microcement should be done with neutral soaps, never with aggressive products or descalers.” (source)

Is it mandatory to apply the mesh for microcement?

Topciment says (read 2026-11-04): “We always recommend applying fiber mesh, especially on tile floors and walls, just like in the joints between plasterboard plates, it is used to arm the base microcement and prevent cracks due to the tensions of the microcement support.” (source) “The final decision to put it or not is up to the applicator, of course, but if they do not add it, warn them of the problems that may arise.” (source)
