Temafloor 400 - Solvent-free epoxy varnish

Temafloor 400
DESCRIPTION A two-component solvent-free epoxy varnish.
PRODUCT FEATURES Used as a binder for Temafloor 4000 grinding screed and epoxy concrete. Used also as a topcoat on top of Temafloor coatings and screeds.
Recommended uses Suitable for dust binding and priming of new and old concrete floors under Temafloor coatings. Filled with sand also suitable for patching of concrete floors.

Features Fire classification according to standard EN 13501 is BFL-s1.
Gloss groups Full-gloss

Coverage on concrete floors is on the average:

Primer                                 5 - 8 m2/l

Topcoat                             6 - 10 m2/l


Practical coverage depends on the porosity and evenness of the substrate and on the application method.

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 80%.

Note! There is a natural tendency of epoxy coatings to chalk and discolor on exterior exposure.
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.

Cementitious levelling screed
Check compatibility with the levelling screed manufacturer.
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.
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 20–30% thinned Temafloor 400 varnish as a topcoat. Pour the varnish mixture onto the floor, spread with a rubber or a steel trowel and level with a roller. Suitable roller is e.g. felt or nylon roller which “distributes” the varnish well. Length of the fluff is approx. 5–14 mm.
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.
