Kent never recovered from being bowled out for just 64 on the first day of play in this year’s cricket s.eason.
No play was possible on Friday due a waterlogged pitch, but when play started on Saturday Gloucestershire bowled the home side out for a paltry total as Zak Crawley topped scored with just 15.
Gloucester then lost eight wickets on Saturday, but managed to establish a lead by scoring 110 first innings runs.
Kiwi Matt Henry was the pick of the bowlers with 4-33 and seven in the match.
Kent then managed 153 in their second innings with Daniel Bell-Drummond top-scoring with 61.
But it meant Gloucestershire needed just 108 second innings runs and won the game just after noon at an overcast St Lawrence Ground.
The West Country team earned 19 points from their visit to Canterbury while Kent took just three.
Kent next travel to Durham for a four-day game starting on Friday.
