Application Procedure
Preparation of the Substrate
The surfaces to be applied should be cleaned in situations that adversely affect rust, mold, oil, loose particles, dust and plaster adhesion, and cracks and holes on the surface should be repaired with BYK 4014 REPAIR mortars. In hot weather conditions, surfaces should definitely be moistened with water. Concrete surfaces should be applied with BYK 1101 PRIMER primer roller before applying to concrete ceilings and walls.
Mixing
The appropriate amount of water described on the package is poured into a clean mixing container. BYK 1011 BOARDFLEX bag is opened and added slowly into the water. It is mixed for about 3 minutes until it is homogenous with 400 - 600 rpm mixing drill. There should be no lumps in the material. After the material is rested for about 3 minutes, it is mixed again for 1 minute and made ready for application.
Mixing Ratio
For 25 kg/1 bag of BYK 1011 BOARDFLEX Gray approximately 6,00-7,50 lt of water should be used. For 25 kg/1 bag of BYK 1011 BOARDFLEX White approximately 7,00-8,50 lt of water should be used.

Watch Points
• In BYK 1011 BOARDFLEX application, suitable temperatures should be expected if ambient and surface temperature are
below + 5 ° C or above + 35 ° C. It should not be applied in extremely hot, rainy or very windy weather.
• In outdoor applications, for the first 24 hours should be protected from sun, rain, wind and freezing.
• Working and reaction times in adhesive mortars are affected by air temperature, humidity and floor temperatures.
• High temperatures accelerate hydration and the working time is shortened accordingly. Low temperatures slow down hydration and thus extend the working time. For the material to be completed, the floor temperature and ambient temperature to be applied must not fall below the minimum permissible temperature.
Shelf Life
Shelf life is 12 months from the date of production when stored properly at +5 oC to +30 oC at room temperature, away from direct sunlight. Opened packages should be consumed within 1 week by closing the mouths.
