Wood glue has been around since ancient times. It may have changed a little in its composition, but it was actually used to fix wooden ships together during the Viking era.
Today, wood glue is used to bond wood together, repair furniture, and even create art.
Check out our article to find the best wood glue available at the moment.
Wood glue comes from tree sap or resin. The resin is collected after trees have fallen and decayed. This is then boiled down into a thick liquid called urea-formaldehyde (UF).
UF is mixed with water and other chemicals to create wood glue.
Wood glue lasts for years. If you apply it correctly, it should last at least one or two years before needing re-application. If you want to extend its life, you can add preservatives such as paraffin wax or shellac.
Wood glue dries quickly. You only need to wait about 30 minutes for it to dry. Once it’s dry, you can use it immediately.
Wood glue is easy to work with. You just need to mix the ingredients together. There are many types of wood glue available on the market today. Some are more expensive than others. However, all will do the same job.
Uses For Wood Glue
There are many benefits to using wood glue. It’s inexpensive and very effective. It’s also environmentally friendly because it doesn’t require any fossil fuels to produce.
There are also many ways you can use wood glue. You can use it to:
• Repair damaged furniture
• Bond wood together
• Make picture frames
• Cover up scratches on wood
Different Types Of Wood Glue
You might not have been aware of this, but there are actually five different varieties of basic wood glues:
Polyvinyl acetate (PVA)
This is the most commonly used and sold wood glue in the world. Brands like Gorilla Glue, Titebond, and Elmer’s Glue are pretty well-known for selling PVA. It’s a very safe type of glue and is only toxic if you ingest it (so make sure you don’t!). It’s best suited for small-scale projects.
This is a much stronger form of wood glue than PVA, and it takes some practice to be able to use it correctly. It has a lower level of moisture content than most other glues, meaning it won’t make joints swell as much. This also means it’s better for applying to wood that has a high moisture content.
Super Glue and Krazy Glue are two popular brands that produce this type of wood glue. It has very good holding properties but is not the strongest variety in general.
It is still stronger than PVA, and it’s more expensive. However, this glue and PVA can be used pretty much interchangeably.
Animal or hide
This is the oldest form of wood glue. It was used for constructing weapons and tools in ancient times though it isn’t quite as effective as most of the synthetic wood glues on the market today.
However, it’s actually not too difficult to make animal or hide wood glue yourself!
The final form of wood glue is epoxy, another very strong adhesive substance. It’s waterproof and can be used effectively as a filler. You can even mix it with sawdust to add some texture to your wood.
How Is Wood Glue Different From Regular Glue?
The main difference between regular glue and wood glue is that the latter contains no formaldehyde. Formaldehyde is a chemical compound found in most glues.
When making wood glue, the process involves boiling down tree sap or resin until it becomes a thick liquid. Then, this liquid is mixed with water and some other chemicals.
These chemicals include formaldehyde which makes the glue sticky and hardens the wood.
Formaldehyde has been known to cause respiratory problems. It irritates the lungs and throat. Children who spend time near their parents while they paint can be exposed to high levels of formaldehyde.
This is why it’s essential to make sure that you don’t breathe in fumes when working with wood glue. You should always wear protective gear including goggles, gloves, and a mask.
What Are The Advantages Of Using Wood Glue?
Using wood glue has several advantages :
- It’s cheap and readily available
- It’s non-toxic and safe to use
- It’s made from natural materials.
It’s also environmentally sound. Unlike traditional glues, wood glue does not contain any formaldehyde. Therefore, there are fewer health risks associated with using it.
It’s also easier to use. All you need to do is mix the ingredients together. No special tools are required.
Another advantage is that it works well. It bonds wood together effectively. It’s strong enough to hold pieces of wood together without breaking them.
Disadvantages Of Using Wood Glove
While wood glue is an excellent product, it has disadvantages too. One disadvantage is that it takes longer to dry than other glues.
Another disadvantage is that it’s not waterproof. This means that if you have a leaky joint, it could seep through over time.
You may also find that it doesn’t bond certain woods together. For example, it won’t work as well with pine.
Best Ways To Use Wood Glue
In order to get the best results, you should follow these tips:
• Mix the ingredients together thoroughly before applying. If you add too much water, the mixture will become runny. Too little water will result in weak glue.
• Apply the glue to the joint where you want it to stick. Don’t apply it directly onto the wood. Instead, start by coating the area with a thin layer of wood filler.
• Wait for at least 24 hours before putting your project together. This gives the glue time to set properly.
• Let the glue dry completely before moving the piece. Otherwise, it might fall apart.
• Keep away from children and pets. They may put things into their mouths that could harm them.
• Avoid breathing in fumes. Make sure that you wear proper safety equipment like masks, goggles, and gloves.
• Store unused wood glue in its original container. Never pour it down the drain because it can clog up pipes.
• Clean up spills immediately. Do not let them sit around. They can contaminate surfaces and soil.
• Always keep out of reach of small children and animals.
Of course, there are plenty of other things to keep in mind when using a tool like wood glue. Make sure you read the packaging carefully to find out about all the safest practices for use for the brand you have.
Wood glue is one of the most versatile products on the market today. It’s inexpensive and easy to use.
You can also expect it to last at least a year or two if you apply it correctly, or even longer if you use some special additives and processes.
