Flooring Porter began his career in the summer of 2019 when he was initially campaigned in Novice hurdle races. On his debut he started at odds of 25/1 at Cork Racecourse on 12 July and came home seventh, beaten more than forty lengths by the winner. He subsequently finished eighth at Ballinrobe Racecourse on 23 June, thirteenth at Galway Racecourse on 3 August and seventh at Ballinrobe on 12 August. As in all of his starts that year Flooring Porter was ridden by Jonathan Moore when he started at odds of 7/1 for a hurdle at Bellewstown on 29 August and recorded his first success as he came from the rear of the field to take the lead at the third-last hurdle and won "comfortably" by seven lengths from Ashton Court.
