OK,
Whilst we're on the subject of sugar deck, candy coated, sticky toffee, confectionery board grips, the easiest method to re-grip a board is a textured deck.
Strapper and Water Cooled used the method for years and it gripped as well as anything else without the Master Chef woes!
Simply mask off the area required to be gripped, apply a medium thickness coat of resin, overlay a sheet of open-weave curtain fabric, wait until the resin is midway through gelling, then carefully peel off.....and hey presto! Great, non-sticky grip!
Reminds me of a story back in the 90's when the night before a Slalom Race, it was mid-winter and I was helping a mate finish building his new race board and it came time to grip it. We had no sugar or salt and ended up using RICE as a deck grip! Coarse? Bloody Oath! Fortunately it was winter and your feet were numb anyway!

Rice Power!
