Glue is one of the most important — and sometimes most frustrating — parts of bookbinding.
If you’ve ever dealt with wrinkled paper, lifting corners, warped covers, or stiff brushes, chances are the issue wasn’t the materials themselves, but how the glue was applied.
PVA glue is widely used in bookbinding because it dries clear, creates a strong flexible bond, and works well with many materials. But like any tool, it works best when you understand how to handle it properly.
Below are a few common mistakes beginners make when working with PVA glue, along with some practical tips that will help your projects come together more smoothly.
5 Common Mistakes When Using PVA Glue
1. Using too much glue
It’s easy to assume that more glue will create a stronger bond, but the opposite is often true.
Too much glue can cause problems such as:
- wrinkling
- seepage through the paper
- warped covers
Instead of applying a thick layer, aim for a thin, even coat of glue. This creates a strong bond while helping the paper and boards stay flat.
2. Uneven glue coverage
If glue doesn’t reach the edges of your paper or book cloth, it can cause lifting later on.
Common signs of uneven glue coverage include:
- weak adhesion
- bubbling
- corners that lift over time
To prevent this, spread glue evenly from edge to edge using a brush or spreader.
3. Working too slowly
PVA dries fairly quickly, especially in warm rooms. If you move too slowly while positioning materials, the glue can begin setting before everything is in place.
This can lead to:
- poor adhesion
- uneven bonding
- lifting edges
A helpful habit is to prepare everything before applying glue. Have your boards, paper, and tools ready so you can work efficiently once glue is applied.
4. Not cleaning brushes
PVA dries quickly and can harden in your brush if it isn’t cleaned right away.
Once the glue dries, the bristles become stiff and difficult to use, which can lead to uneven glue application.
To keep brushes in good condition:
- rinse them immediately after use
- or leave them in a jar of water while you finish your project
5. Letting PVA freeze
PVA glue can be damaged if it freezes. Freezing may cause the glue to separate or become lumpy, which weakens its bonding ability.
If glue has separated or developed a chunky texture after freezing, it’s best to replace it.
To avoid this issue, store PVA at room temperature.
General Glue Tips for Bookbinding
Beyond avoiding common mistakes, a few simple habits can make working with glue much easier.
Store glue in a stable container.
A heavy-bottomed jar helps prevent spills. Placing a piece of wax paper between the lid and the jar can also keep the lid from sticking.
Choose the right brush for the job.
A brush that’s too small for a large project can slow you down and allow the glue to dry too quickly. A brush that’s too large can apply too much glue.
Smooth glued surfaces carefully.
Placing parchment paper over the glued surface and smoothing it with a bone folder helps remove air bubbles and ensures good contact between layers.
Check if the glue is fully dry.
If a recently glued book cover feels cool to the touch, it likely still contains moisture and needs more time to dry.
Tips for Gluing Book Covers
When gluing paper or book cloth to book board, a few additional considerations can help prevent warping and other issues.
Match the grain direction.
Make sure the grain of the cover paper and endpaper runs in the same direction as the spine of the book.
Apply glue to the thinner material.
Spread glue on the paper or book cloth rather than directly on the book board. This allows the paper to expand slightly and helps prevent the boards from warping.
Use balanced materials.
When covering book boards with machine-made papers, using papers of a similar weight on both sides of the board helps keep the board flat as it dries.
Apply glue from the center outward.
Applying glue in a star pattern from the center outward and brushing in one direction helps distribute the glue evenly and prevents it from spreading onto the front of the paper.
A Small Skill That Makes a Big Difference
Glue work may seem like a small part of bookbinding, but good glue habits can dramatically improve the quality of your finished books.
A thin, even layer of glue, good preparation, and careful smoothing go a long way toward creating covers and structures that stay flat, strong, and beautiful over time.
If you’re new to bookbinding, don’t worry if glue work feels a bit tricky at first. Like many parts of the craft, it becomes much easier with practice.
Hi! I’m Ali Manning
Years ago, I learned about handmade books, and ever since then, I’ve been hooked. I love creating new designs, learning about different techniques, and expanding my collection of paper. But what I love most about bookmaking is the community.
Through Vintage Page Designs and the Handmade Book Club, I’ve met thousands of other passionate bookmakers, mixed-media artists, and crafters. We all share a love of book arts and crafting, just for the joy of it.
I believe that bookbinding and book arts are for everyone, regardless of skill level or equipment. All you need is a little creativity and, of course, paper!
Very helpful. Thank you.
Thank you, I learned some great techniques, especially gluing from center out. ❤️
Can you tell us which glues generally available online and in the crafts stores are PVA glues, such as Alene’s Tacky glue, Art, Glitter Glu, Bearly Arts Glue, others? Thank you.
These are so helpful! It took some practice to get this right when I first began binding books. It seems like such a simple thing, but as you pointed out, it has a lot of variables and can affect your books in the end. Thank you, Ali!
