In my home made pizza dough making, this is definitely a problem i have. I pretty much quit making dough for my pizza oven, because everything sticks to the peel. All three of them. Store bought dough, or recipe from my local pizza guy. Only thing that doesn’t stick is pre shaped pizza.
That's unfortunate.
Worst sticking we had was once when my wife wiped the wood peels down with a damp towel without me knowing. The little residual moisture resulted in a mess in the oven. Only happened once, lol.
I have two wood peels for loading pizza into the oven. As someone else mentioned, I also use semolina. I sprinkle some on the wood peel, then rub it around with the palm of my hand, working the excess off the edges of the peel. I use a high hydration dough (48 hour poolish prep) and haven't had any sticking, even with a stretched and loaded round sitting on the peel for up to 10 minutes waiting to be loaded into the oven. Dough balls are about 280g give or take, stretched to 12"-13" rounds.
When I take the dough out of the rising box, I have some semolina on the countertop. I'll drop the dough into the semolina, flip it over a couple of times to coat (not really "coat", but...) both sides, then shape the dough on a clean counter. Dough is soft, supple, and no stick. Flavor and texture is quite good.
