Advice for preparing a new concrete floor for painting

[barlow23]

I have had a new concrete floor laid in my garage and want to paint it. I have Ronseal diamond hard garage floor paint but would like to know what I have to do beforehand to seal it. Is there a solution I can use or would I have to screed it?

use a pva solution on the floor and when its still damp lay a self level compound on the floor and trowel flat
