Finncoatings® Color on the highest level

 

Important! Please do not add any air when stirring the paint as this is included in the paint film depending on the drying conditions. This would lead to an impairment of the surface and the load-bearing capacity of the coating.

TEMAFLOOR  PU

DESCRIPTION    
A solvent free, elastic two-component polyurethane coating.


PRODUCT FEATURES
   
For new and old concrete and asphalt floors exposed to mechanical and chemical stress in industrial and storage facilities, repair shops; e.g. air handling units, process or paper machine units and corridors.

APPLICATION DETAILS

Application conditions
   
The relative humidity of the concrete should not exceed 97%. The temperature of the ambient air, surface or coating should not fall below +15ºC during application or drying. Relative humidity of air should not exceed 70%.


Preparation     


New concrete   Finncoatings®color on the highest level

Remove laitance by power grinding, vacuum grit blasting or hydrochloric acid etching. Choose the method best suited for the premises. After grinding remove dust carefully with a vacuum cleaner. Hydrochloric acid etching is carried out with diluted hydrochloric acid (1 part concentrated hydrochloric acid, 4 parts water). Rinse with plenty of water. Dry the floor.

Old concrete
Remove all grease, oil, chemicals and other impurities by detergent washing. Remove old peeling paint layer by grinding, milling or vacuum grit blasting. Choose the method best suited for the premises. Clean out pot-holes removing all loose friable material. Open cracks with e.g. an abrasive tool. Remove loose material and dust.
Cementitious levelling screed
Check compatibility with the levelling screed manufacturer.
Priming     Prime using Temafloor 400 epoxy varnish thinned 30–50% with Thinner 1029. Pour the varnish onto the floor and apply as much as is needed to impregnate the concrete surface. If necessary, repeat priming to get a non-porous surface. Subsequent treatment can be carried out after 2 hours using "wet-on-wet" technique. A porous priming coat will result in holes and air bubbles in the finished screed. Scatter sand of grain size Ø 0,1–0,6 mm on the fresh primer coat to ensure the screed adhesion and prohibit gliding of the screed. Remove loose sand with vacuum cleaner before coating with Temafloor PU.
Asphalt floors should be primed by applying Temafloor PU with a suitable steel trowel.

Patching
    Finncoatings®color on the highest level  
Patch pot-holes and cracks with unthinned Temafloor 400 epoxy varnish and dry, clean sand. Mixing ratio e.g. 1 part by volume of epoxy mixture and 1 - 2 parts by volume of sand of grain size Ø 0.1–0.6 mm. Grind the patched areas before overcoating.

Diluting     Do not thin Temafloor PU polyurethane coating.
Coating     Overcoating may be carried out not earlier than 16 hrs and not later than 24 hrs after priming and patching. If the primed surface is not overcoated within 24 hrs, it should be abraded. Pour the coating mixture onto the floor and spread it with a serrated steel trowel or an adjustable trowel. Control that the thickness of layer is correct by observing coating consumption and by measuring the film thickness. Recommended thickness of a layer is 1.0–2.0 mm. Level the screed with a spiked roller approx. 10–20 min after application. Spiked roller helps removing air bubbles from the coating.

Note! Add the remaining mixture to the next batch of the screed, do not scrape it out of the container onto the floor.

Mixing of components
   
Mix the correct proportions of base and hardener thoroughly (approx. 2 minutes) by using a plaster mixer. The amount of mixture depends on the area to be coated and on the pot life of the mixture. Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface, weaken the properties of the coating and risk the success of the application.
