With a foam brush, there are no bristles to lose, and it will not leave brush marks in your finish and these American made foam brushes really are the best we've ever tried. There is nothing worse than applying paint, varnish or stain to a project only to find the brush has shed its loose bristles all over your smart, new finish. They are a pain to remove and more often than not, they damage and spoil your finish.
The specially formulated polyurethane foam absorbs the finish consistently and allows it to spread out uniformly across the width of the foam giving a smooth, even flow. This means that fewer strokes are needed to cover the work. A polyethylene insert gives the foam support and stiffens it to a bristle like flexibility.
