A Postsaver Pro-Sleeve is a heat-shrinkable sleeve lined with a meltable, bituminous liner.
Pro-Sleeves are heat applied to wooden fence and gate posts to create an air and watertight barrier around the vulnerable ground line section of the post. This proven dual-layer barrier locks preservatives in and moisture + fungi out, making conventional ground-line decay impossible.
Unlike liquid coatings and bitumen paint, Postsaver maintains a barrier to the causes of decay when the post cracks or splits.
