Temafloor 401 - Solvent-free epoxy varnish

Temafloor 401
DESCRIPTION A two-component solvent-free epoxy varnish.
PRODUCT FEATURES A low viscosity varnish used as a binder for Temafloor 4000 grinding screed.
Recommended uses Concrete floors.

Features Fire classification according to standard EN 13501-1 is BFL-s1.
Colour Range Sunlight will affect on the shade and the gloss of the varnish in the long run.
Gloss groups Full-gloss

For a flat substrate:

1 mm layer: 1 litre ready for use screed / m2

5 mm layer: 5 litres ready for use screed / m2


Practical coverage depends on the evenness of the substrate.

1 part by volume TEMAFLOOR 401 mixture
6 - 8 parts by volume of filler sand, e.g. grain size of 1.0 - 1.8 mm

Note! The amount of the filler and the grain size depends on the object.
Application method Pour the varnish mixture onto the floor, spread with a rubber trowel and level with a roller.
Pot-life (+23°C) 20 - 30 minutes on substrate, 10 - 15 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

Recoatable after 16 - 24 hours

Fully cured 7 days
Solids volume approx. 100 volume %
Density 1.1 kg / litre (mixture)
Product code 008 4002

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 +1ºC during application or drying. Relative humidity of air should not exceed 80%.
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 MAALIPESU detergent. Remove old peeling paint layer by grinding 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 about 30% 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 the priming to get a non-porous surface. Subsequent treatment can be carried out after 2 hours using "wet-on-wet" technique.
Scatter sand of grain size 0.5 - 1.2 mm on the fresh primer coat to ensure the screed adhesion and prohibit gliding of the screed.
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 epoxy mixture and 1 - 2 parts by volume of sand of grain size 0.5 - 1.2 mm.
Overcoating Overcoating should be done within 16 - 24 hrs after priming. If the primed surface is not overcoated within 24 hrs, it should be abraded. Use unthinned Temafloor 400 varnish for the topcoat. Pour the varnish mixture onto the floor, spread with a rubber trowel and level with a roller.
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.
