Board repair question

Hi guys,
I having bit of trouble fixing up my board.
I have bumped my board on the street and it cracked little.
I thought it was water-tight but when i put the board under the sun, water was coming out from the crack (with little bubling sound).
My question is, how do you know when the board is fully dry so i can put resin on to seal it?? i have been putting the board out under the sun to dry for 2 days and it's still damp when i touch it.
Also, is there anyway to make it dry faster other than just drying under the sun?? e.g use a lighter?
Cheers
