Eamon Vize opened the scoring with a header from a Jamie Maynes corner while Jordy Toal made it two after great work by Caleb Keating, John Neill and Maynes.
Vize then hit the woodwork and Keating went close with a header before Maynes got his just desserts when he added a third at the beginning of the second half.
Toal then completed his hat-trick before Conor Magee added the sixth.
Nico McDaid and Eoin Madden were excellent in the second half with Conor O’Toole getting the man of the match plaudits and John Mulholland kept another clean sheet.
