Application Instruction
Surface Preparation: The surface to be applied Teknofast must be clean , slightly humid or without water lake. The surfaces to be applied must be without cement residue ,the derbis must be repaired. If there are water pressure from negative and efflorescence ,the product should not be applied.

Application: Teknofast is applied by two had spraying machine. It have two nozzle one of them sprays Teknofast bitumen side and the second one sprays the hardener/accelarator so two of them combined out of the nozzles and seamles mebrane forms. Teknofast and hardener ratio is 10:1 by
volume. Teknofast bitumen side must be mixed at last 5 min before spraying. The hardener is solid must dissolved at the clean water. Hardener concentration water:hardener is 9:1 by weight. To obtain 4mm dry thickness approximate consumption is 6,5 kg/m2. Complete dry is depend on weather condition may vary between 5-7 days. In any confusion please contact with Tekno Construction Chemicals expert.

Priming: In the case of using primer, the accelarator part or valve should be switched off and only bitumen emulsion part should be sprayed out aproximately 200 g/m2. The suitable drying time for primer at 23⁰C is one hour.

Application Notes/Restrictions
• During the application process personel protective clothes and protective gogless should be used
• The Spraying process must be repeated via spray gun on vertical and horizontal directions until the desired final film thickness.
• Teknofast can be applied on moisty surfaces, not on the puddle water.
• Teknofast is ready for use, it should not be diluted. it should be avoided to add some metarilas extarnally
• In the case of rainly, frost weather condition the application must be postponed
• After the completion of curtain wall insulation at under ground application, the coated surface must be protected by extruded polystyrene boards,drainage sheet etc.
