| DESCRIPTION | A solvent free, two-component polyurethane coating. | ||||||||||||||||||||||||||||||||||
| PRODUCT FEATURES | For new and old concrete and asphalt floors exposed to mechanical and chemical stress. | ||||||||||||||||||||||||||||||||||
| RECOMMENDED USES | Concrete floors in industrial and storage facilities, repair shops; e.g. process or paper machine units and corridors. | ||||||||||||||||||||||||||||||||||
| TECHNICAL DATA | |||||||||||||||||||||||||||||||||||
| Features | Good resistance to abrasion. Withstands water, oils, greases, chemicals and dilute solutions of non-oxidizing acids, alkali and salt solutions. Resists only temporary splashes of oxidizing acids and bleaching chemicals. Withstands + 80 ºC dry heat and + 60 ºC in immersion. Does not resist abrupt changes of temperature. Good impact resistance. Self-levelling, to be applied with serrated or steel trowel. Fire classification: BFL-s1 according to EN 13501-1. | ||||||||||||||||||||||||||||||||||
| Colour Range | TVT 0229. Sunlight will affect on the shade and the gloss of the coating in the long run. | ||||||||||||||||||||||||||||||||||
| Gloss groups | Full-gloss | ||||||||||||||||||||||||||||||||||
| Coverage | Practical coverage depends on the porosity and evenness of the substrate and on the application method. Film thickness 0.3 mm coverage approx. 3 m2/litre Film thickness 0.5 mm coverage approx. 2 m2/litre For coating: 1 mm layer: 1 litre ready for use screed / m2 2 mm layer: 2 litres ready for use screed / m2 |

| 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 + 15 ºC during application or drying. Relative humidity of air should not exceed 70 %. | ||||||||||||||||||||||||||||||||||
| Preparation | New concrete: 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. |
||||||||||||||||||||||||||||||||||
| Priming | Prime using 30 - 50 % with Thinner 1029 thinned TEMAFLOOR 400 epoxy varnish. 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 | 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 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 low speed hand drill with a paddle. 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. | ||||||||||||||||||||||||||||||||||
