Decorative, thin-layer polished concrete floor, PCC, thickness 8-15 mm
Bautech ULTIMA Baufloor® is a thin-film polymer-cement (PCC) system solution for creating exclusive, floated and polished concrete floors with a marbled texture.
When polishing you can get a depth effect (3D), discoloration and shading on the floor surface.
This is based on polymers, hard aggregates, high-performance cements, admixtures and pigments.
Thin-layer system, thickness 8-15 mm
High abrasion resistance
High impact resistance
High dusting resistance
High chemical and mechanical resistance
Mirror shine, the possibility of shading the surface
Smooth, even, hard surface
Easy to clean
Low floor maintenance and care costs
A wide range of colors
For indoor use
For making decorative, even, smooth, resistant to abrasion and wear, polished concrete floors on new and renovated concrete surfaces.
For indoor use: in apartments and public facilities with heavy pedestrian traffic: shopping malls, shops, religious buildings, restaurants, offices, car showrooms, gastronomic premises, at airports, stations, etc.
Substrate moisture - max. 4%
Air humidity - max. 75%
Substrate temperature - min. + 5 ° C.
The substrate temperature should be at least 3˚C above the dew point temperature.
The ambient temperature during work and for the next 5 days should be between + 15 ° C and + 25 ° C.
The surface should be protected against rapid moisture loss, loss of moisture due to e.g. high temperatures, drafts, solar radiation, etc.
At least 3 days before laying Bautech ULTIMA floor, the floor heating should be turned off.
All work should be carried out using appropriate tools. Installed floor should be protected against dust, dirt and contamination.
An adequate lighting should be provided.

The concrete slab must be stable, durable and should withstand expected static and dynamic loads. Concrete at least C20 class or screed with a minimum pull-off strength of 1.5 N / mm². The substrate humidity must not exceed 4%. If the substrate is uneven or non-homogeneous, first make an epoxy screed based on Bautech BAU-POX 100 ST ® resin.
The surface should be cleaned mechanically, e.g. by shot blasting or grinding. Weak or soft substrates that can be cracked and deformed under load should be removed. Cement milk, all types of dirt and old protective coatings must be removed mechanically by grinding, shot blasting or milling.
WAY OF APPLICATION
Product: Bautech BAUPOX 100 ST® -epoxy resin
Properly mixed epoxy resin should be spread on a concrete slab in one or two layers using a rubber squeegee and roller to achieve full concrete saturation. Then the quartz aggregate should be tossed onto the wet epoxy in the amount of approx. 3.0 kg / m2 - full broadcast. After the polymerization of epoxy the surface should sanded with sandpaper and vacuumed thoroughly.
Coverage: 0,30 – 0,50 kg/m2
Product: Bautech ULTIMA®
To 3.2-3.6 litres of clean, cool water add 25 kg (bag) of Bautech ULTIMA and mix for 3-4 minutes with a mixer until a homogeneous mass is obtained. Let stand for about 3 minutes and mix again briefly.
Prepare portions that will be used within approx. 15 min. Do not add more water than the instructions recommend as this will reduce strength and increase mortar shrinkage. In winter periods, the material should be kept in a heated and dry room before mixing.
The low temperature of the material may cause that some additives may not be able to dissolve when mix-ing. Too high temperature may reduce the mortar
slump and its fast curing. The mixed Bautech ULTIMA ™ mass should be applied onto to the previously prepared substrate and spread onto the right thickness with a PIN Gauge Rake. After the surface has hardened to such an extent that it can be stepped on without leav-ing too deep of trace, the surface should be power floated with a metal disc. After each power floating check the floor level. All corners should be manually trowelled with steel trowels with a particular emphasis on perfect levelling of the floor. After preliminary power floating with a disk (levelling of the floor sur-face) one should continue floating with blades.
We smooth the surface by gradually increasing the angle of inclination of the blades. The whole cycle lasts from 6 to 12 hours and is divided into a few power floating cycles (depending on the area and tempera-ture). During the last floating, so-called surface burns and discoloration of the material that give an irregular and individual pattern to the decorative floor appear.
Discoloration patterns rarely occur in the manual pro-cessing zone (wall line, corners, places inaccessible to the machine)..
NOTE: All contraction and expansion joints in the substrate should be sawn within 24-72 hours after floor installation and filled with Bautech BAUFLEX ™ expansion joint filler.
Coverage: about2 kg/m2/ 1mm of thickness
SEALING AND POLISHING
Product: Bautech NANOSEAL®
(lithium-polymer sealer for freshly power floated concrete).
Immediately after the power floating process is completed, the entire surface should be coated/sprayed with Bautech NANOSEAL ™ to prevent Ultima slab from losing moisture too quickly. Spread the sealer in to a thin layer by using a high-quality microfiber mop not to leave streaks on the floor surface, avoiding the formation of puddles.
One can additionally protect the floor against excessive evaporation of water until polishing, e.g. with a painting foil.
Coverage: 1 litre per 4-10 m2
Product: Bautech NANOCOAT® polishing agent). Final polishing effect is achieved by the application of Bautech NANOCOAT ™ and using polishing pads. For best results, spray the floor with Bautech NANOCOAT ™ and spread it out by using a high-quality microfiber mop not to leave streaks on the floor surface as they may affect the aesthetics of the final finish.
Important: The mop must be moistened with water before use. After drying (approx. 60 min.) the surface should be polished with delicate (white) pads or special diamond polishing pads that increase the polished surface temperature to approx. 30 ° C.
Coverage: 1 litre per 20-60 m2
SPEAD OF CURE
At + 20oC and 60-70% relative humidity:
foot traffic: after 24 hours
mechanical loads: after 72 hours
full wear resistance: 7 days after floor sealing
loads: light after 14 days, heavy after 28 days from the floor installation
NOTE: the floor is not resistant to metal wheel loads.

The final appearance of installed floor may show differences in shade depending on the conditions and the way of application, drying conditions, etc. This is not a product defect and does not affect the technical parameters and performance of the floor. The colour variation of the floor can also be the result of a heterogeneous substrate. Bautech colour samples should be considered as demonstrative only. The final appearance may differ from the presented Bautech samples depending on the way of application, grinding, power floating, polishing. If in doubt, make your own tests or contact the Bautech Technical Department.
