I used acrylic paint on my floor. 2 coats. If you want to do a quilt block, start with a solid color floor and then use blue masking tape to outline the squares you want to paint. after each color is dry remove the tape and put down tape for the next color. Make a detailed drawing with excat dimensions so you won't have odd shaped pieces.
Good luck. definitely go for it !!!
I saw a marvelous set of stair risers with quilt blocks painted on them. really eye catching
