Keep in mind that the instructions for any wood glue were developed in an ideal setting, and your mileage may vary depending on your environment. The biggest factor to consider is humidity. In environments with low humidity, you can expect your project to dry faster. Meanwhile, in high humidity environments, it can take considerably longer for the glue to dry. The ambient temperature of your workspace also can affect drying time and proper curing. It can be helpful to take a look at the bottle and see the temperature range the glue operates best under.
Wood glue dries by dehydration. Some of the moisture from the glue is lost to evaporation, and the rest of the moisture is sucked up by the wood itself. One of the most important things to remember when gluing up a project is the difference between when the glue is dried vs. Curing takes significantly longer to occur than drying. Wood glue typically takes a day or so to fully cure. So do heed any on-pack instructions with regard to acceptable temperature ranges or you could end up with a piece that isn't bonded together properly even after the temperature has subsequently risen.
That assumes dry wood and that the joint is well-fitted and not particularly stressed. Sign up to join this community. The best answers are voted up and rise to the top.

Aliphatic resins, therefore, generally need to be clamped in minutes , with slower-drying varieties extending this to around minutes. Most aliphatic resin wood glues need hours to reach full strength. Often referred to as CA glues or instant glues by woodworkers and crazy glue or super glue by DIYers and hobbyists, cyanoacrylate adhesives are well-known for their fast drying times.
CA wood glues are usually the fastest drying. Polyurethane glues are usually multi-purpose, sticking everything from wood to metal. One of the biggest benefits of polyurethane glues is that most varieties are waterproof, making them ideal for outdoor projects. Most polyurethane wood glues need to be clamped for at least 2-hours and require hours to reach full strength. Several different types of epoxies are available, but the most popular types are two-part, consisting of a hardener and a resin mix.
Epoxies can be used to bond various materials, not just wood, and they have excellent chemical and water resistance that makes them a good option for outdoor applications. Rapid setting epoxy wood glues can start to dry in as little as one minute and reaching handling strength in minutes.
Most epoxy glues require hours to reach full strength. Unlike most glues on the market, which are chemical-based, hide glue is a natural type of wood glue typically made from the bones or hide of cattle. Because of this, hide glues are non-toxic while still providing a reasonable degree of water and chemical resistance. Hide glues start to set relatively quickly, and the majority of hide glues should be clamped in less than 20 minutes.
It takes around hours for a hide glue to reach full strength. Hot glues, or hot melt adhesives, come in a stick that melts when pushed through the nozzle of a hot glue gun.
A significant disadvantage of hot glue is its poor heat resistance, which causes it to return to liquid form when reheated. Hot glue typically remains workable for less than 60 seconds , depending on how much adhesive is applied. There are plenty of other factors to look at when it comes to how quickly a glue dries. It is possible to dilute water-based glues for example, PVA glues to make them last longer or less viscous in other words, runnier , with Titebond recommending adding a maximum of five percent water , for example.
It is possible to apply wood glue to wet wood, and in some cases, it is the recommended approach. Polyurethane wood glues, for example, are moisture activated, meaning a degree of surface moisture is needed, or else the adhesive will not start bonding.
