Wherever they are used, at whatever time, it is very important to let the glue dry properly. When it doesn’t cure and dry properly, the glue will come off and the fix will be of no use. Most of the time, a clamp will also be needed for the joint while drying. Though a length of paper tape can be used on the joint while the glue dries, it is only so much effective for minor repairs. For repairs a little larger, it is better to use woodworking clamps.

The clamps as well as the wood glue are not expensive, yet very effective.

Why Does It Take That Long For Wood Glue To Dry?

Drying and curing are very different, as drying is referred to as the time taken for the glue to dry well enough to be touched. Curing time is longer than that, and it lasts as long as the chemical reaction between the wood and glue lasts. After the glue dries well, the clamp can be removed as the joint will be secure enough. The drying time can differ based on multiple reasons like the type of glue, how well it is preserved while it is drying, and much more.

The common type of glue includes polyvinyl acetate, otherwise commonly known as PVA or white glue. Though the glue can be clamped for about 30 minutes, it can take about a day for the glue to cure fully. Polyurethane can be used to fill the gaps and cracks between many other different materials, not only wood and the time of clamping is about 2 hours, while the curing time is around a day.

Conclusion

The epoxy contains both the resin and the harder and it is thicker than the other wood glues. They are used for minor repairs and since they are thick, they are waterproof and can be screwed or drilled into. While rapid-set epoxy takes about 6 hours to cure, the normal types take around a day almost. Cyanoacrylate, otherwise known as superglue dries every quickly and fixes small repairs in minutes and the curing time is about 8 hours to a day.

Other reasons why wood glue takes time to dry can be based on the temperature of the air, humidity, and moisture content in the wood, and the environment. Some wood glue is water activated, while some can lose its power when they are exposed to water. It is necessary to look after the drying area and maintaining the right conditions.
