Tikkurila Temafloor PU UV is a solvent-free polyurethane paint, that has excellent UV-resistance and withstands mechanical and chemical stresses. It's also a high-solids, flexible and weather resistant two-component polyurethane coating.

Temafloor PU-UV is a self-leveling paint and creates seamless smooth surface. The coating is mostly used for e.g. parking decks, footpaths and other areas exposed to abrasion and direct sunlight.

Features & Benefits

• Excellent resistance to UV
• Silent, does not shrink or crack
• Withstands mechanical and chemical stress
• Self-levelling, to be applied with serrated or steel trowel
• Intended to be used as a UV-resistant topcoat on Temafloor PU floors in parking decks and other areas exposed to direct sunlight

Technical Data

Surface 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 surface.

Old Concrete

• Remove all grease, oil, chemicals and other impurities by Maalipesu detergent.
• Remove old peeling paint layer by grinding.
• 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.

If cementitious screed is used, check compatibility with the levelling screed manufacturer.

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%

Mixing Components

• First stir base and hardener separately.
• Mix the correct proportions of base and hardener thoroughly (approx. 2 minutes to get homogenous mixture) by using a low speed industrial hand drill with a paddle.
• 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.

Application

Priming:

• Prime using Temafloor 400 epoxy varnish thinned 30–50% with Thinner 1029 or Fontefloor EP Primer epoxy varnish thinned about 20-50% with water.
• Pour the primer 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.
• A porous priming coat will result in holes and air bubbles in the finished coating.
• Subsequent treatment can be carried out after 2 hours using "wet-on-wet" technique.
• Asphalt floors should be primed by applying unthinned Temafloor PU with a suitable steel or rubber trowel.
• 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 UV.

Patching:

• Patch pot-holes and cracks with a mixture of unthinned Temafloor 400 epoxy varnish and dry, clean sand.
• Mixing ratio e.g. 1 part by volume of varnish mixture and 1–2 parts by volume of sand of grain size 0.1–0.6 mm.
• Sand the patched areas before overcoating, if necessary.
• Note! Concrete surface should always be primed before patching.

Topcoating:

• Overcoating may be carried out not earlier than 24 hours after coating with Temafloor PU.
• If the primed surface is not overcoated within 24 hrs, it should be abraded.
• Pour the mixture onto the floor and apply it with a trowel and level with a roller.
• Control that the thickness of layer is correct by observing coating consumption and by measuring the film thickness.
• Recommended layer thickness is 1.0–2.0 mm.
• Use spiked roller to finish the surface approx. 10–20 min after application. Spiked roller helps removing air bubbles from the coating.

Thinner/Cleaning

Thinner:

• Do not thin Temafloor PU UV polyurethane coating.

Cleaning of equipment:

• Thinner 1061

VOC

• VOC 2004/42/EC (cat A/j)500 g/l (2010)
• Temafloor PU UV: max. VOC < 500 g/l
