LINECO Neutral pH Adhesive, 4 Oz, Acid-Free, All-purpose Glue, Dries Clear and Remains Flexible, Used for Bookbinding and Book Repair, Framing, Collages, Paper Art and Crafts

I first discovered this product in the process of repairing some of my old books. When I ordered certain volumes, they would arrive with the spine partially unhinged or the dust jacket possessed tears that threatened to grow with time. In search of a fix, I repeatedly read online the value in using acid-free paper and glue for any repairs. As a result, I bought some durable Japanese mulberry paper.With paper ready, I had to find the right glue. Most websites, aside from preventing acidity, also emphasized the need for flexibility and durability. Wheat paste was the best option. Some people prefer to make their own paste, and while Lineco does sell a wheat starch, I ultimately went with this PVA alternative because I was afraid of bungling the process. While it is a synthetic polymer, it seems just as effective as the natural alternative.Some of the other reviewers express disappointment that their glue came out chunky, but I had no such issues. I can only assume the damage came about during the shipping process. My glue exits the tube with an even, smooth consistency. You do need to apply slightly more pressure than normal to get it to first emerge.The only additional work beyond opening the packaging was piercing the top of the container. The glue comes with a nipple, however, to ensure a longer shelf life. Once I applied it to the books and jackets for repairs, I was thrilled at how it turned out. It is a relatively quick drying glue, but I recommend leaving it alone for at least three or four hours in a stable position. My book jackets now stay in place, but with enough flexibility to allow for normal, cautious handling. With it being PH-neutral, my repairs should last for decades to come.My only complaint, if you can call it one, is cost. I felt that the product is reasonably priced and the bottle is relatively large, but if someone is unaware of what type of projects it is typically used for, they might think it is overpriced for normal school assignments or children’s crafts. For professional purposes, it is a great, affordable item. I highly recommend it and will purchase again in the future.
