Impossible to manage sticky dough
Unfortunately, your link does not seem to be working for me right now, but assuming you are making a leavened bread dough, here's some tips. Let me know if you've tried all these before.


Wet your hands before handling the dough. This will temporarily keep the dough from sticking to your hands but be warned: this effect will not last forever. Make sure to keep wetting your hands as you go.
If you're getting near baking time, go ahead and flour the surface and your hands. Ge generous with the flour, too little will find yourself elbow-deep in dough with no way out
With the scraper, wet the scraper a bit before using it to reduce "drag" on the dough.


If you could provide more details on the exact makeup of the dough, that could provide more insight, but that's all I have for you right now.
