  • Easy implementation
  • High mechanical and chemical resistance
  • For indoor and outdoor applications
  • Wide range of colours

The temperature of the ambient and foundation during the works and for the next 5 days should be between +5°C and +30°C. The surface made should be protected from losing water too quickly as a result of, for example, high temperatures, draught, sunlight operation etc. In order to ensure high quality and uniform colour, all works should be performed with suitable tools in an area protected from dust, EPS balls and similar impurities.



The foundation must be of carrying capacity, hard, stable, dry, compact, with no cracks and free from impurities. The compressive strength of the concrete foundation should be no less than 25 N/mm2 and the peel strength - no less than 1.5 N/mm2. The foundation should be cleaned mechanically, e.g.: by shot blasting or milling. Weak or soft foundations (such as asphalt), which might crack or deform under loads, should be removed.

In order to level the surface, universal polymer-cement floor base UNIFLOOR can be used, according to the technical sheet of the product.

Ground the foundation with BAUGRUNT, according to its technical sheet (grounding under MICROTERRATOP) and leave to dry. On the founda-tion prepared in this way apply bonding layer of BAUBOND and spread with a hard brush (detailed information on the bonding layer is included in the technical sheet of BAUBOND). Then start applying prepared MICROTERRATOP mortar.


MICROTERRATOP mortar can be applied on the surface of freshly-made floor concrete, of low contraction properties, class no less than C20/25, made in accordance with design assumptions, or on univer-sal polymer-cement floor base UNIFLOOR in accordance with the technical sheet of the product.

Before mortar MICROTERRATOP is spread, the concrete/base must achieve proper hardness. The setting time of concrete/base depends on the temperature, relative humidity of the air etc. The surface of the concrete base must not get too hard, therefore its condition must be frequently checked. As a result, selection of the optimal moment to begin application of MICROTERRATOP mortar will be possible. The works may be commenced when the imprints of feet on the concrete/base are not deeper than 3-4 mm. Remove excess of cement grout from the surface of the concrete/base and refresh it with a disc. Then start applying prepared MICROTERRATOP mortar.



To 3.0-3.3 l of clean, cold water pour 30 kg (a bag) of dry MICROTERRATOP mixture and mix for 3-4 minutes in a concrete mixer or with a slow-running drill with a mixer until a homogenous mass is obtained. Prepare portions which will be used within about 15 min. Do not add more water than the instructions indicate, as this will decrease the strength and increase the contraction of the mortar. In the wintertime the material should be kept in a heated room prior to mixing. Low temperature of the material may cause that some additions will not be able to dissolve during mixing. Too high temperature of the material will decrease the spread of the mortar and result in too quick bonding.



Spill prepared MICROTERRATOP mortar on the foundation and spread to the desired thickness using a distance scraper or a long float along with a laser levelling instrument or spacer strips, while smoothing the surface with a long float until uniform, smooth structure is obtained. During application workers should walk on BAUBOND bonding layer and on the fresh floor in spiked boots.

When the surface hardens to a degree that it can be stepped on without leaving too deep traces, troweling with power trowel should be com-menced.

The initial troweling should be made with a disc and subsequent ones with blades set at gradually larger angles, until a smooth, even surface is obtained. Immediately after the troweling process is completed, but not earlier than when shoe imprints may be left on the floor, maintenance preparation TERRASEAL should be applied in the amount of about 0.15–0.20 l/m2. Apply the sealer on the dry surface with spraying method and spread it with a microfibre mop, until the entire surface is covered, so that the floor remains wet for 15 minutes. Repeat the application in faster drying places.

When the maintenance preparation has completely dried up, cover the surface with polyethylene sheet to provide additional protection from external factors. The sheet should be left on the floor throughout the maturation period until the grinding works begin. Expansion joints should be cut when the saw blade does not tear the aggregate off MICROTERRAFLOOR. The sheet should be removed from the floor for the time of these works. When the contraction joints are cut, the whole surface should be covered with sheet again. Filling of joints with BAUFLEX sealant should be per-formed during or immediately after the grinding works on the top surface of MICROTERRAFLOOR are completed.

Operating conditions of maturing MICROTERRATOP

Pedestrian traffic is permitted 7 days after the building in, complete load of the floor may be used after the grinding process, but not earlier than 28 days from the moment of building in. 7 days after building in, if the temperature does not drop below 20ºC, the grinding process may be commenced. Lower temperature will slow the maturation process down and extend the period after which grinding may be started.

The surface of the floor must be homogenous and free from impurities. Before commencing the grinding process, all impurities (dirt, dust, oil spills, impregnations, care products) should be removed mechanically and all defects and damages repaired.

Necessary tools:

Levighetor Max (concrete up to 500m2) or Expander 750 (concrete over 500m2)

SuperVak KY 80 vacuum cleaner

Metal diamonds: DT0,DT1,DT2 (240mm)

Polishing diamonds: MCK 3, MCK 4, MCK 5, MCK 6, MCK 7 (75mm)


The grinding process is started with metal diamond discs Klindex DT 0 placed on the planetario. Grind the floor until perfectly even level is achieved. Repeat the process using metal disks Klindex DT 1, DT 2. The walls must not be approached, as this may cause breaches; the recommended safe distance is 5 cm. Also, working crosswise is recom-mended (first grind the surface from up down and from down up, then from right to left and from left to right.) While working with diamond and metal disks DT diamonds should be sharpened with Aktivator. The next stage is work with polishing disks. This will finally eliminate shallow scratches. Commence works with diamonds Klindex MCK 3. Grind also crosswise, but this time the walls can be approached. When the works with disc MCK 3 is completed, the floor must be vacuum-cleaned and washed.

The next stage is the application of TERRASEAL. Apply the preparation on the dry surface with spraying method and spread it with a microfiber mop, until the entire surface is covered, so that the floor remains wet for 15 minutes. Repeat the application in faster drying places. Then wait 3-6 hours depending on the ventilation of the room.

The next stage is grinding using diamonds MCK 4, manner of work like in case of MCK 3.

The final stage is polishing of the floor using diamonds MCK 5, MCK 6 and MCK 7 and brightening with natural hair pads and TERRACOAT preparation. When the grinding process is finished, apply TERRACOAT preparation on dry, clean and vacuum-cleaned surface. TERRACOAT should be applied using a high-quality microfiber mop, so that no streaks are left on the surface, as these will remain visible and will negatively influence the appearance of the floor.

When the surface has dried up (after about 60 minutes), it should be polished with a delicate, white pad or special diamond polishing pads which increase the temperature of the polished floor to about 30°C. Depending on the required gloss, the activity may be repeated 2-3 times.


Before commencing polishing works, it is recommended to perform a trial fragment of the floor measuring about 5m2 in order to establish the wear and consumption of the tools, chemical agents and to establish the final effect that will be achieved.

Losses in the floor, which happened due to mechanical works, should be completed with TERRAFILL, in accordance with the technical sheet of the product.

All contraction and expansion joints as well as working cracks in the foundation should be reconstructed in the applied layer of MICROTERRATOP mortar and filled with BAUFLEX sealant or BAUFIX filling insert.


The equipment and tools should be cleaned with water immediately after use. Hardened material can only be removed mechanically.


The mixture contains cement - mixed with water gives an alkaline reac-tion. Avoid breathing, protect eyes and skin. In case of contaminations: clean eyes with plenty of water, wash skin with soap and water. Working areas should be ventilated. Keep away from the children.
