Bautop® Enduro - metallic hardener for industrial floors

BAUTOP® ENDURO WTW
Metallic hardener for industrial floors – WTW system (wet to wet),
CT-C60-F10-A3

 

Bautop Enduro metallic hardener wet-to-wet

BAUTOP® ENDURO is a metallic surface hardener (WTW) for mono‐lithic concrete floors. It contains hard aggregate, high‐performance cements and proper admixtures and pigments. Applied and troweled on freshly‐made concrete, it creates a coloured, marble‐like, abrasion and dusting resistant, smooth floor of increased resistance to the penetration with oils, grease etc.


USE
  • New surface‐hardened floors of high hardness and resistance to abrasion and dusting in heavy traffic facilities – production plants, warehouses with very intensive traffic, factories, logis‐tic centres as well as in food and pharmaceutical industry fa‐cilities etc.
  • Anti‐electrostatic floors.

For professional use only.

 

PRODUCT CHARACTERISTICS
  • Very high resistance to abrasion
  • High dusting resistance
  • Contains abrasion‐resisting metallic aggregates
  • High impact resistance
  • Easy to clean
  • Sealed and non‐dusting surface
  • Frost‐resistant
  • Wide range of colours

 

CONCRETE SLAB

BAUTECH WTW SYSTEM floors are used on surfaces of freshly‐made low‐shrinkage concrete:

  • class C20/25 or higher
  • w/c ratio ≤ 0,50
  • amount of cement ≤ 350 kg/m3
  • alkali contents in cement <0,5% li="">
  • cement CEM I, CEM II/A-S, CEM II/B-S or CEM III/A
  • aggregate ≤ 16 mm
  • contents of fraction ≤ 0.25 mm ‐ min. 4%
  • sand point about 35%
  • total amount of cement and aggregate of fraction ≤0.25 mm – max. 450 kg/m3
  • addition of steel fibres BAUMIX and polypropylene fibers BAUCON by recommendation of BAUTECH ‐ if an anti‐electrostatic floor is being made, the concrete must have an addition of BAUMIX steel fibres in the amount of no less than 20 kg/m3; also a discharge of electrical charges must be performed.
  • consistence on the construction site: S3, Abrams cone slump about 12 cm. Addition of steel fibres decreases the slump.

In case of outdoor surfaces, concrete of exposure class XF4 should be used.

CAUTION! Do not add any volatile ashes, as these tend to accumulate in the top layer of the slab, which may cause the dusting of the floor or detachments of the hardenER. It is forbidden to add water to concrete mixture in order to increase its workability. This causes a significant loss of the strength of the concrete and a clear increase of the chemical and physical shrinkage, leading to the creation of uncon‐trolled scratches and cracks.

The concrete must be properly compacted.

 

APPLICATION CONDITIONS

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.

METHOD OF USE

To make the floor with “wet on wet” method surface hardener BAUTOP® ENDURO is used. Before the mortar is spread, the con‐crete must achieve proper hardness. The setting time of concrete depends on the temperature, relative humidity of the air etc. The surface of the concrete must not get too hard, therefore its condi‐tion must be frequently checked. As a result, selection of the optimal moment to begin application of the mortar will be possi‐ble. The works may be commenced when the imprints of feet on the concrete are not deeper than 3‐4 mm. Remove excess of cement grout from the surface and refresh it with a disc. Then begin the spreading of prepared BAUTOP® ENDURO mortar.

 
Preparation of the mortar:

To 3.0‐3.5 l of clean, cold water pour 30 kg (a bag) of dry 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. Spill the prepared mortar on the foundation and spread to the desired thickness using a distance scraper or float along with a laser levelling instrument or spacer strip, while smoothing the surface with a long float until uniform, smooth structure is ob‐tained.

Prepare portions which will be used within about 15 min. Do not add more water than the instructions indicate, as this will de‐crease 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 mor‐tar and result in too quick bonding.

Perform the subsequent stages of troweling with blades set gradually at increasing angles.

CURING

Immediately after the troweling is completed, the whole surface should be treated with a selected preparation in order to prevent too quick loss of water:

BAUSEAL® EKO

A water‐diluted sealer for industrial floors applied with the spraying method, with a low‐pressure sprayer. Sealer should be applied once, with a thin layer, paying attention that no puddles are left.

Efficiency: 1 litre per 8‐12 m2

 

BAUSEAL® ENDURO

A solvent‐based sealer for industrial floors applied on freshly made concrete floor, immediately after the last mechanical troweling is done. Sealer should be applied with the spraying method, with a low‐pressure sprayer. Sealer should be applied once, with a thin layer, paying attention that no puddles are left.

Efficiency: 1 litre per 8‐10 m2

 

BAUTECH FORMULA®

Silicate and polymer based agent for the maintenance, strengthening and sealing of concrete surfaces. BAUTECH FORMULA should be applied evenly on the surface with the spraying method in the amount of 0.1 ‐ 0.2 l/m2 until complete coverage is obtained.

The surface should stay wet for 15 ‐ 20 minutes. An additional amount of the agent should be applied in places where it dries up faster – a microfiber mop helps distribute the agent evenly and maintain the surface wet for the necessary time.

Efficiency: 1 litre per 4‐10 m2

 

 

NANOSEAL®

Lithium and polymer based agent for the maintenance, strengthening and sealing of concrete surfaces. Thanks to the penetration and hard‐ening of concrete in molecular structure, it allows to obtain a highly resistant cement matrix of extreme physical and chemical properties. Additional modification with a specially selected polymer binding agent provides the maximum level of sealing the concrete by bonding those ingredients of the concrete matrix that are devoid of free cal‐cium compounds.

NANOSEAL should be applied evenly on the surface with the spraying method in the amount of 0.1 ‐ 0.2 l/m2 until complete coverage is obtained. The surface should remain wet for 15 ‐ 20 minutes. An additional amount of the agent should be applied in places where it dries up faster – a microfiber mop helps distribute the preparation evenly and maintain the surface wet for the necessary time.

Efficiency: 1 litre per 4‐10 m2

 

HEALTH AND SAFETY PRECAUTION

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