How to Choose the Right Wood Glue?

Picking the right type of wood glue suited for your task depends on the material that you want to work. Indoor and outdoor applications also play a critical role. There are different kinds of wood glue, and each type is not for the same purpose. It is also beneficial in understanding how to store the wood glue properly because of its components. Aside from the classes, here are the features to help you choose the right wood glue.

Bond StrengthIt refers to the strength and tension that the wood glue can handle measured by pounds per square inch (psi). Moreover, it also includes the flexure, compression, and capacity to hold any impact.
Clamp TimeIt refers to the period of gluing two pieces of material needs in clamping.
Closed Assembly TimeIt is the period that allows the pieces to stick to their final position.
Chalk TemperatureIt is the critical temperature in “chalking,” wherein it occurs when the glued joint loses strength failing to bond. It is because of the loss of water during evaporation that pulls the adhesive particles together for drying.
Freeze-thaw StabilityThe wood glue can sustain after its freezing point. Low Freeze-thaw Stability will make it hard to get back to its original form.
Open Assembly TimeIt is the amount of time required between the initial wood glue application and putting the substrates.
Speed of SetIt refers to the rate wherein the wood glue builds strength.
Storage LifeIt refers to the period until when you can store the wood glue under specified temperature conditions.

Tips for Using Wood Glue

  • For newly purchased wood glue, remember that the average shelf life is 12 to 24 months. After that, it may start losing its binding potency. There are ways to prolong its shelf life, but you have to be accurate.
  • Always clean the nozzle of the wood glue bottle to avoid any clogging issues.
  • Use gloves when using polyurethane. Most woodworkers call them the “super-glue” because it can stick on your fingers, which may be hard to remove.
  • Read the instructions on the back of the wood glue if you get your hands glued. Consult a medical expert if the wood glue went directly into your eyes.
  • Apply thin coatings with two to three layers. Spread the Glue evenly to make sure that it dries the fastest time possible.

How to Use Wood Glue?

Use your wood glue properly to speed up your woodworking projects and improve the quality of your workpiece. Make your project look better whenever you use wood glue with these steps in using it and some helpful tips. Regardless of the kind of Wood Glue, here’s a general guideline in using most of them.

  • STEP 1: Choose Your Wood Glue Wisely. Use of Plain Old Wood Glue is Still the Best. There are various kinds of wood glue out there from multiple manufacturers claiming to work well on wood. If you are unsure of your options, you will never go wrong with old wood glue. It has formulated components that can penetrate wood fibers that make the joints stronger than wood.
  • STEP 2: Waterproof Glue. It is better to look for waterproof wood glue for versatility. Waterproof Glue comes from both PVA and polyurethane formulas, which makes it sturdy and can withstand any weather.
  • STEP 3: Mask Glue Joints. For healthy quality joints, you have to glue them before finishing. It is because wood glue doesn’t stick well to varnished or stained wood. You can apply good-quality masking tape to the surfaces that you have to glue if you want to finish the other parts. Or you can do the finishing touches after pasting the pieces together.
  • STEP 4: Apply the Wood Glue. Using a flux brush, apply and spread the right amount of wood glue. Flux brushes are excellent, especially for sticking intricate joints. Moreover, you can also use it to cover the wood glue on some slots. You can also rub the edges of the joints with Glue before clamping. Put just the right amount of it.
  • STEP 5: Join Two Joints. You can use steel bar clamps or pipe clamps to hold the joints. However, you may want to cover the jaw pads with wax paper in case the wood glue comes in contact with the brace. The moisture of the Wood Glue can also leave dark marks on your wood, watch out for that.
  • STEP 6: Let the Wood Glue Set. Depending on the amount of Wood Glue, let it sit for at least an hour or two. Some would even require to cure for 24 hours. It takes longer, but it is the most effective way to ensure that the joints don’t move and that the Wood Glue dries completely.
  • STEP 7: Shave off the Excess Wood Glue. Once the Wood Glue has completely dry or turned into a darker gel appearance, you can shave off the excess parts using a sharp chisel. It will clean the joints than removing it when it’s in super hard condition. You can use an abrasive pad to remove dried Glue in the most intricate surface of the joint.




Does Wood Glue Dry Faster in Hot or Cold?

A warm environment helps in drying the Glue faster because its air can absorb more water from the surroundings of the Wood Glue. However, too much heat may cause abnormal consistencies to the adhesive. So, be careful in using warm air. If you want to dry fast, you can use a hairdryer on a low setting.

Tips for Making Wood Glue Dry Faster

Drying the wood glue may take more than an hour or more. This process takes longer than expected sometimes. However, it is something that you can’t avoid. The good news is that you can, at least, dry the wood glue faster with these tips.

  1. Newer Wood Glue the Better. Use something that hasn’t reached its expiration, yet. It is because age positively affects the performance of the wood glue, which includes its average dry time.
  2. Don’t Dilute the Wood Glue. Never water down because it won’t work. The diluted wood glue will only saturate the wood joints, which can make everything hard rather than sticky. What’s worse? It can ruin your adhesive bond.
  3. Get Proper Air Flow. Work in an area where it has excellent ventilation. It helps in drying the wood glue faster. On the other hand, use a dehumidifier if you live in a more humid climate. A warm environment also helps in absorbing more water from its surroundings.
  4. Correct Way of Application. The best way to apply wood glue is through thin and even coatings. Otherwise, thick layers won’t give you any good results.
  5. Use Clamps. It helps in setting the wood glue properly and makes sure that the wood joints are in the right position. Holding the wood pieces by your hand for a few hours may result in inaccuracy with the workpiece.
  6. Mix Glue Plus Resin. Resin works like epoxy, which adds more hardener to the mixture of your wood glue. It accelerates the drying time while making sure of active support. However, you have to work quickly because the solution hardens instantly.
  7. Use of Polyurethane Wood Glue. It is a popular option for wood joining because it is waterproof. Polyurethane Wood Glue absorbs water from the glued objects causing the adhesive to expand and fill the space.




Is Wood Glue Stronger Than Epoxy?

Epoxy is stronger than other kinds of wood glue, while others have just the same strength. Epoxy is excellent in filling the gaps in the wood. However, it takes more time to cure but guaranteed stronger the longer you wait. Choosing between Wood Glue and Epoxy depends on your preference.

How Can You Tell If Wood Glue Is Bad?

First of all, the Glue is terrible if it doesn’t do an excellent job of sticking the wood joints. Also, the too vicious or too watery texture is a sign of lousy kind of Wood Glue. You have to make sure that it has the right sticky consistency. It should flow nice and smooth, and it is not clumpy nor stringy. Otherwise, the Wood Glue may want to stick to itself than gluing the wood joints.




What Are the Kinds of Wood Glue?

Every type of wood glue that you can see on hardware stores has various chemical makeups, which allows them to work on particular surfaces. We have discussed the different kinds of Wood Glue in our article entitled Why Does Wood Glue Turn Black? At a glimpse, here are the different types of Wood Glue.

Carpenter’s GlueIt came from a chemical called aliphatic resin, which holds two workpieces stronger. You can sand it over safely once the wood glue gets dry, but it has a low resistance to wood stains.
Urea-formaldehyde GlueIt is another plastic resin glue that features water-resistant properties, but it is only ideal for indoor furniture. 
Resorcinol GlueIt is the most durable type of wood glue, which is 100% waterproof suitable for both indoor and outdoor purposes. 
PVA GlueIt means Polyvinyl acetate, which is colorless and odorless. It is widely available almost everywhere. 
EpoxyIt consists of two parts, which includes a resin and a hardener. Epoxy is that they are 100% waterproof, and it is excellent in filling the gaps to match joints perfectly.
Polyurethane GlueIt dries quickly and very hard, which makes it ideal for both indoors and outdoors.
Hide GlueIt comes from animal hides, which hardens well, and the excess adhesive does not affect the finish of your project.
Cyanoacrylate GlueIt is the best Glue for joining thick pieces the fastest time as possible. 

How to Store Your Wood Glue for it to have a Longer Life?

Manufacturers provide the official shelf life of their wood glue on its bottle to protect themselves, in case of poor storage conditions causing product failures. As mentioned, most Wood Glues last for approximately one to two years. You have the advantage to exceed the expected shelf life of most Wood Glue – here’s how.

  • For both white or yellow Wood Glue like polyvinyl acetate and PVA glue, you have to store it in a sealed bottle in optimum conditions.
  • A dry and cool environment is the most excellent place to store and keep Wood Glues. It is enough to maintain the right temperature that Wood Glues requires to keep its consistency.
  • Putting the Wood Glue in a refrigerator with the right temperature helps in extending its shelf life. However, you have to avoid freezing, thawing, and extreme heat conditions.
  • Wood Glues can only withstand a minimum of five cycles of freezing or thawing. Each period, Wood Glue forms a gel structure. However, each cycle makes it harder to disperse and return to its original form.
  • It may be more challenging to break up the gels, and the wood will remain solid after five cycles of freezing or thawing point of Wood Glue.
  • Shake the Wood Glue vigorously if it gets thick. Tap the bottle on a hard surface, until you restore the original form of the adhesive. You can also add five percent water to water-based glues like PVA to make the consistency thinner.
  • If the Wood Glue becomes stingy or pasty, it’s already due. There’s nothing you can do to save it but to buy a new bottle.
