The victors dominated almost every sector of the pitch in the opening half and were 13 points clear by the interval.
They stormed into a 0-4 to 0-1 lead after five minutes through points from Nicky Kirwan, Frank Cullen and David Redmond, with Pat Doran on target for the losers.
They continued to pick off scores at will before Rory Jacob’s goal seconds before the break had them 1-13 to 0-3 clear at the change of ends.
Buffers Alley resumed with a Stephen Redmond point within 30 seconds of the restart but the expected comeback failed to materialise, as Oulart’s defence were to the fore.
They were 1-17 to 0-6 ahead when Jacob had his second goal after 38minutes.
Sub Keith Burke had a goal for the losers soon after but it counted forlittle as Oulart eased through the final quarter to advance to another county decider.
In the opening semi-final contest veteran Paul Codd inspired Rathnure to a 2-18 to 0-15 victory over Cloughbawn.
Two goals inside the opening 10 minutes laid the foundation for victory. The first came from Brendan O’Leary after two minutes, with Robbie Codd adding the second from an acute angle, seven minutes later.
Rathnure led 2-5 to 0-10 at the interval and the accuracy of Codd from placed balls kept his side ahead while Cloughbawn were overly reliant on the free-taking of Paul Foley for scores.
