best glue for book spine repair

There are several types of glue that can be used for book spine repair, depending on the specific needs and materials of the book. Here are a few options:

1. Polyvinyl Acetate (PVA) Glue: PVA glue is a popular choice for book repairs because it is acid-free and flexible when dry. It is suitable for most paperbacks and hardcovers.

2. Epoxy Resin: Epoxy resin is a strong adhesive that can be used for more heavy-duty repairs, such as repairing hardcover books with thick spines. It provides a durable bond but may not be as flexible as PVA glue.

3. Bookbinding Glue: There are specialized bookbinding glues available that are designed specifically for repairing book spines. These glues are often pH neutral, flexible, and have good adhesion properties.

4. Hot Glue: Hot glue guns can be used for quick and temporary book spine repairs. However, hot glue is not recommended for valuable or antique books, as it can be difficult to remove and may cause damage.

It is important to note that the choice of glue may also depend on the specific type of book and its condition. It is always recommended to consult a professional book conservator or a knowledgeable librarian before attempting any repairs on valuable or delicate books.
