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 +10ºC during either application or drying. Relative humidity of air should not exceed 80%.
Preparation New concrete
Remove laitance by power grinding 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. 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 (or 1031) thinned Temafloor 200 Primer or 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 coat.
Patching Patch pot-holes and cracks with Colofill or unthinned Temafloor 200 Primer varnish mixed with clean, dry sand, grain size 0.1-0.6mm. Mixing ratio e.g. 1 part by volume of varnish mixture and 1-2 parts by volume of sand. Grind the patched areas before finishing.
Note! Concrete surface should always be primed before patching.
Finishing Pour the well stirred mixture of Temafloor 310 ESD primer onto the floor, apply with a rubber trowel and level with a roller. ESD priming should be carried within 6-24 hours afrer priming with Temafloor 200 Primer epoxy varnish. If the surface is not overcoated within 24 hrs, it should be abraded.
Installation Connection to earth:
The floor primed with Temafloor 200 Primer should be connected to earth with copper coils. The installation of copper coils is designed according to site. Glue the copper coils, the area of which should be at least 20cm2, to the surface primed with Temafloor 200 Primer. Use flexible coils at joints. The coils should be connected to earth. Connection points of walls must be treated with isolating material.
Mixing of components First stir base and hardener separately. Mix the correct proportions of base and hardener thoroughly (approx. 3-5 minutes) by using an 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 screed and risk the success of the application. Thin the mixture 20-30% with Thinner 1029.
Cleaning of tools Thinner 006 1029 (or Thinner 006 1031).
