TEKNOFLOOR 200F
Rollable epoxy coating
- 2-component
- 2-component
TEKNOFLOOR 200F is a two component, solvent-free epoxy coating for concrete floors.
Use: Concrete floors whenever a paint coat resistant for hard abrasion is required. TEKNOFLOOR 200F is a low viscous, self-levelling, solvent-free floor coating, which is also free from benzyl alcohol. Suitable for both priming and top coating as roller application. The product has CE approval for protection of concrete structures.

Surface preparation
NEW CONCRETE SURFACES: The concrete must be at least 4 weeks old and well-hardened so that all moisture from casting is bound and the surface dry. The moisture of the concrete must not exceed 97% as relative humidity or 4% by weight (by 54 / BLY 12).
Dense laitance is to be removed from steel-trowelled concrete by shot-blasting or surface grinding. Brittle and powdery top layers are treated so that the solid concrete containing aggregate is exposed. Thereafter all cement dust is removed by vacuum cleaner or brush. The concrete surface must be clean of anything that might hinder the adhesion.
Surface grinding is a good method to remove laitance from the floor. It is usually done on new industrial floors as wet grinding in connection with casting. Shot-blasting is another excellent method for removing laitance. Etching is used if grinding or shot-blasting cannot be used. It is mainly recommended for small areas.
Etching is to be done with RENSA ETCHING etching liquid. Rinse the floor with water after etching and allow to dry. On the concrete surface must not be anything that will prevent the adhesion.
OLD CONCRETE SURFACES: Uncoated, greasy floors are cleaned by e.g. emulsion wash. Thereafter laitance is removed by surface grinding or etching. Flaking old paint, and laitance can be removed by diamond-wheel abrading, blast-cleaning, shot-blasting or wet grinding
Crevices and cavities are to be repaired before the first application with TEKNOPOX FILL Stopper or with stiff putty prepared by mixing an adequate amount of dry sand (grain size 0.1 - 0.6 mm) with solvent-free TEKNOFLOOR PRIMER 310F Epoxy Varnish.
Application
MIXING OF THE COMPONENTS: The base and hardener are thoroughly mixed together for 2 minutes. Mixing by machine is recommended, for example a slow-rotating hand-drill equipped with a mixer. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties.
PRIMING COAT is applied "wet-to-wet" with paint that is diluted by 10 - 30 % with TEKNOSOLV 9506 or TEKNOSOLV 9515. TEKNOSOLV 9515 has milder odour and can therefore be used in spaces, where strong smells are to be avoided. Apply the paint generously, so that the surface is sealed. Pour the paint on the floor and apply with short-piled roller. Recoat immediately all areas that have absorbed the paint completely. The number of priming coats depends on the quality of the concrete surface. The priming coating may have to be done several times.
TOP COAT is applied 8 - 24 hours after the priming with undiluted paint. Apply enough coating to get a uniform, thin film. The application is done the same way as for the priming coat.
It is recommended that paint of the same batch is used for painting large uniform floors and avoid mending by re-rolling already partly dried surfaces. If paint from different batches must be used, the application is to be planned so that the seams between batches are done to natural lines, i.e. sills and expansion joints.
Wear spike-soled shoes when walking on fresh paint surface.
Application conditions
During the application and drying period the temperature of the ambient air, the surface and the product shall be above +10°C and the relative air humidity below 80%. Additionally, the temperature of the surface to be treated and the product must be at least +3°C above the dew point of the ambient air.
Storage
The storage stability is shown on the label. Store in a cool place and in tightly closed containers.
