The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. Pull-off strength must be not less than
1.5 N/mm². If in doubt, apply a test area first. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.
Prior to application confirm relative air humidity and dew point. Divide the area to be coated into parts for the number of A + B units, to have consumption under control and to know how far to paint with each A + B mixture. The rollers should be wetted in the first area, which should be taken into account by pouring out some more material. The roller will absorb approx 0.3-0.5 kg coating a. With a small quantity mixed product, pre-coat the edge areas with brush and small roller. But never go further ahead then 10 minutes to the regular rolling, to obtain minimal visibility. Within the pot-life (as soon as possible) depending on the temperature 20 min (30°C) – 40 min (10°C) the produ ct is poured and spread out on the substrate under observation of the coverage rate (+/- 130 g/m2). Attention: the end of the pot-life is not noticeable!
After pouring out, the material has to be spread in the pouring direction with theroller and with the same roller cross to pouring direction, covering approx. 1.35 m
wide not overlapping the former lane, and backwards covering approx 1.45 m with a overlap of less than 5 cm. Porous spots where the skin of sub layer is “opened” by sanding such as after repairs, have to be pre-coated a few minutes before arriving there with the regular roll-out to minimise visibility. Then change to a short piled
roller and extend the overlap, in a calm way to approx 10 -20 cm. See to it that no glittering shiny spots will be left in the finished paint layer caused by paint pick-up
from the surface by the roller. A seamless finish can be achieved if a “wet” edge is maintained during application
