Ireland played with the wind in the opening half and young Lansdowne centre Mark Roche thought he was in for a try in the opening minute but knocked on over the line after he hacked on a loose ball inside the Scottish half.
Both sides were finding it difficult to hold onto the greasy ball and the Tom Tierney-coached hosts opened the scoring on 13 minutes.
A move involving Gerry Hurley, David Joyce and Stuart Morrow sent full-back Daniel Riordan in for a try in the corner, bursting through from outside the 22.
Joyce added a penalty from a scrum minutes later and the tricky Riordan - Old Belvedere's captain this season - was in for his second try in the 27th minute following good work from Joyce and Michael McGrath. Joyce converted for a 15-0 lead.
Riordan's elusive running from deep and out wide was too much for the Scottish defence to handle and the two-try back was a deserving Ulster Bank man-of-the-match award winner.
Peter Jericevich kicked a penalty for Scotland eight minutes before the interval, but that was cancelled out immediately by a Joyce three-pointer to leave the score 18-3 at half-time.
Ireland enjoyed the better of the exchanges in the second half despite playing into the wind and with the rain lashing down.
Cork Constitution scrum half and captain Hurley - playing at his own club ground - extended the Irish advantage with a fine try in the 49th minute, gathering the ball on the 10-metre line and finding a gap to score.
Ten minutes from time, replacement prop Declan Lavery scored Ireland's fourth try in the corner after they had disrupted a Scottish lineout inside their 22.
The result completed a clean sweep of victories for Ireland against Scottish opposition, following on from last week's triumphs by the men's, women's and Under-20 teams.
