Preparation and priming
The substrate should be clean and free from dust, cement, grease or other impurities which might prevent weber.floor 4716 from adhering to the substrate.
For correct film formation the substrate temperature should not fall below +6°C. For best results the temperature of the work area should be between +10 and +15°C.
Mixing
weber.floor 4716 should be diluted with clean water according to the ratios given in the Technical Data.
To obtain the correct mixed ratio, always measure the water into a plastic container and add the concentrated primer.
Addition of water to the concentrated primer may result in foaming. The dilution of water and primer is easily mixed with a wooden stick.
Application
The primer solution should be spread evenly over the prepared floor surface using a soft brush or spray, avoiding ponding, and allow to become touch dry (3 – 5 hours under normal conditions)
After application and while the primer is still fresh, it should be lightly brushed to ensure a complete uniform film has been applied.
Drying time
3 – 5 hours (under normal conditions).
Overnight (under poor conditions).
Cleaning
Once dried, weber.floor 4716 is difficult to remove so care should be taken to clean tools quickly before the primer dries.
