Despite a spirited performance from the visitors, Wanderers were well in command throughout with Eoin Ryan and Eric Marah controlling the run of play.
Stephen Doody impressed for Buttevant and came close on a couple of occasions while leading his line up front.
But, it was Wanderers who were soon into their stride with Dave Riordan firing straight at the Buttevant keeper in the opening minutes.
And after Mick Murphy had to make a near-post save from Mark Riordan, Eric Marah set Mark Riordan up to fire low past the advancing Murphy between the sticks for Buttevant to hand Wanderers an early advantage.
A careless clearance from the Buttevant keeper handed Marah an opportunity, but his effort to loop over the out-of-position net-minder never came off.
Buttevant’s Dylan McCarthy produced an impressive run in on goal, but a sharp tackle by Matt Anthony put a sudden halt to the threat.
Buttevant won a corner on the left and from the delivery; the ball breaks for Stephen Doody who cracked a decent effort over.
At the other end, Mark Riordan won the race over Mick Murphy to a ball over the top, but failed to lift his effort into an empty net.
Soon afterwards, a terrific ball into space from Eoin Ryan set Eric Marah up to produce a wonderful crisp finish to double Wanderers’ advantage on 18 minutes.
Dave Riordan then had a great chance to add another for Wanderers when Eric Marah’s measured through ball played him in, but he steered wide of the target with just the keeper to beat.
Play shifted to the other end with Dylan McCarthy producing a decent run that took him in towards goal, but the alert Rob Lyons got a well-timed block in – in the nick of time.
Buttevant did have a half-chance after that, but Dylan Finnegan skewed wide with a low effort from a favourable position.
Wanderers found themselves further in front though and it arrived as a result of a sweeping move with Marah playing it on for Dave Riordan who produced a slide-rule cross for Mark Riordan to help home and make it 3-0 on 33 minutes.
Wanderers continued on the front foot and shortly before the break, John McCleverty forced Mick Murphy to save with his legs from his crisp effort before Mark Riordan drilled narrowly over from 25 yards out.
With just four minutes into the second period, Wanderers extended their lead after Dave Riordan squeezes Mark Riordan’s cross home to hand the hosts a commanding 4-0 lead.
Buttevant refused to be bowed though and after Stephen Doody sees his decent effort sail narrowly wide, Victory Ufoh’s goal-bound effort was blocked by McCleverty.
A great chance fell for Buttevant after that, but Paddy Behan failed to get a touch on Diarmuid Doody’s cross.
Stephen Doody was to have another couple of near misses before Scott Chambers put the icing on the cake when he grabbed Wanderers’ fifth near the end.
