In some cases, you can use your anchor tape as a seam tape. This usually only works on light duty jobs. The main issue that jobsites run into while using an anchor tape to seam is durability. For example, Painter’s Grade Blue Tape isn’t designed to handle high traffic areas. A jobsite often endures workers with boots, heavy equipment being rolled in and out, building material being moved around, and the occasional dropped tool. This kind of activity can be a bit much for Painter’s Grade Blue Tape.
On the other hand, Polyethylene Tape is much more durable and features a non destructive amount of adhesion, but it isn’t exactly a cheap tape. Depending on the size of your job, you could be using more seam tape that you might expect. This tape is useful for anchoring when you expect to do a lot of work towards the edge of your surface protection area, such as wall installations and window work.
