Floetrol is a water-based paint conditioner which makes interior and exterior emulsion and acrylic paints including coloured wood stains work more like oil-based paints. It helps to improve paint flow and workability and allows the paint to adjust to more difficult conditions such as hot, cold and windy environments. Arguably most importantly, it helps to eliminate brush and roller marks by improving the flow of the paint giving a much more professional finish and helping you to make progress more quickly.
