Both are typically based on polyvinyl acetate, but they’re formulated for different jobs.

• White school glue: Usually a lighter, washable PVA blend designed for paper crafts, classrooms, and slime. It tends to have lower initial tack and is easy to clean up with water.
• Wood/craft PVA: Thicker with stronger tack for porous materials like wood, paperboard, and fabric. Many dry clear or to a natural wood tone, and some are paintable, sandable, or water‑resistant.

If you need a stronger bond for woodworking, frames, or MDF, a dedicated craft or wood PVA is often a better fit. For everyday kids’ projects, a washable school glue can be more convenient. Always check the label for terms like “PVA,” “polyvinyl acetate,” and intended uses.

Look for clear cues on the label and product details.

• Ingredient callouts: Mentions of “PVA” or “polyvinyl acetate.”
• Category clues: Wood glue, bookbinding adhesive, picture frame glue, and many white school glues are commonly PVA‑based.
• Feature phrases: “Water‑based,” “cleans up with water,” “dries clear,” “paintable,” or “sandable.”
• Specialty notes: “pH neutral” or “archival” are often used for book and paper work.

If the label doesn’t explicitly say PVA, scan for these signs and the recommended materials (wood, paper, MDF, fabric). When in doubt, the product description typically lists chemistry and best uses so you can quickly confirm whether it’s a PVA adhesive.

PVA glue is versatile for many porous surfaces and craft projects.

• Woodworking: Bonding joints, assembling frames, and small repairs on interior projects. Some formulas offer water resistance for broader use.
• Paper & board: Scrapbooking, cardmaking, mounting, and collage work where clear‑drying, flexible bonds are helpful.
• Bookbinding: pH‑neutral PVA is popular for spines, covers, and repairs.
• Fabric & crafts: Light fabric projects and mixed‑media crafts.
• Multi‑surface tasks: Certain PVA blends are made for materials like ceramic, stone, or glass; always verify on the label.

Because it’s water‑based, cleanup is straightforward. For non‑porous plastics or high‑heat/wet environments, consider checking whether the specific formula is recommended for those conditions.

PVA can help reduce absorbency on MDF edges and faces before finishing.

1. Prep: Lightly sand, especially cut edges, and remove dust.
2. Thin coat: Brush on a thin, even layer of PVA; some users dilute slightly with water for better penetration on edges.
3. Dry: Allow it to dry thoroughly; avoid heavy puddles that can form a glossy film.
4. Repeat if needed: A second light coat can further reduce soak‑in.
5. Finish: Once dry, proceed with primer, paint, or your chosen adhesive.

Results can vary by formula, humidity, and surface prep, so testing on a small area first is a good idea. Follow the product’s directions for ventilation, application, and drying times.

Choose a PVA suited to paper work and apply with a light touch.

• Select the type: For books and archival projects, look for “pH neutral” or “archival” PVA that dries clear and flexible.
• Apply thinly: Use a brush to spread a smooth, even coat on spines, covers, or mounts. Thin layers help minimize wrinkling.
• Align and press: Position carefully, then press with a bone folder or stack of books to encourage contact while drying.
• Dry fully: Allow adequate drying between steps before trimming or moving to the next stage.

Different papers absorb adhesive differently, so test on a scrap first to confirm adhesion, flexibility, and finish.
