PRODUCT DATA SHEET
Temafloor PU-UV - Polyurethane coating
|DESCRIPTION||A high-solids, elastic two-component polyurethane coating.|
Intended to be used as a UV-resistant topcoat on Temafloor PU floors in parking decks and other areas exposed to direct sunlight.
|Recommended uses||Concrete floors.|
|Features||Withstands mechanical and chemical stress. Self-levelling, to be applied with serrated or steel trowel.|
|Colour Range||TVT 0229. The shade and gloss of the coating may change during time.|
Practical coverage depends on the porosity and evenness of the substrate and on the application method.
Film thickness 0.3 mm coverage approx. 2.7 m2/litreFilm thickness 0.5 mm coverage approx. 1.8 m2/litre
|Mixing ratio||Base 2 parts by volume 473 serie
Hardener 1 part by volume 008 4001
|Application method||Serrated or steel trowel.|
|Pot-life (+23°C)||40 minutes on substrate, abt. 20 minutes in the mixing container.|
|Drying time at 23°C and 50% relative air humidity||
Dust dry after 6 hours
Light trucking after 24 hours
Fully cured after 7 days
At lower temperatures the curing process will last longer.
|Solids volume||Approx. 90 % volume|
|Density||1.4 kg / litre (mixture)|
|Product code||473 serie|
|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||Remove dust and loose particles from the floor. Remove all grease, oil and other impurities by detergent washing.|
|Diluting||Do not thin Temafloor PU-UV polyurethane coating.|
|Coating||Overcoating may be carried out not earlier than 24 hrs after coating with Temafloor PU. If the coated surface is older than 7 days, 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 0.3 -1.0 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.|
|Cleaning of tools||Thinner 006 1061.|
