Hi guys. I've just poured my first river table with some nice oak. I Maybe didn't leave enough time between pours as the temperature is 13/14 degrees. It was probably too sticky still. Anyways its shrunk and I need more resin to Complete the table. It's my first time ever working with resin. If anyone has tips about pouring onto an already cured river would be greatly appreciated. Be it sanding etc. Thanks, Daniel 

I had a similar issue a few weeks back so you should be able to find my post easy enough. Temp should be 20 degrees for glasscast 50.
Will be fine though so just scratch it up with some 240 grit paper
