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 +5ºC during either application or drying. Relative humidity of air should be 50–90 %.
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 and let the floor dry.

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.

Cementitious levelling screed
Check compatibility with the levelling screed manufacturer.
Priming Prime using unthinned Temafloor 25 Clear. Pour the varnish onto the floor and apply evenly. If the primer is absorbed into the concrete, repeat the priming immediately using "wet-on-wet" technique.
Do not thin Temafloor 25 Clear.
Patching Patch pot-holes and cracks with a mixture of Temafloor 200 Primer epoxy varnish and dry, clean sand of grain size 0.1–0.6 mm. Prepare the filler by adding a sufficient amount of sand into the varnish. Grind the patched areas before overcoating.
