Today’s topic is wood glue. If you are going to do simple household repairs, if you work with crafts or if you own a carpentry shop, you certainly need this tool to achieve the ideal results!
There are several types of glues that can be applied to wood. What is normally sold under the name “wood glue” is yellow PVA, but as we will see in the course of the article, it is not always the best option.
So, to get all your doubts about this matter, stay with us! We will pass on all the necessary information for you to do the best job possible.
First, the most important
- The most common glues for bonding wood to wood are white PVA, yellow PVA and crushing glue or Hide Glue (Titebond). They all have their advantages and disadvantages.
- It is not just any wood glue that can be used for all types of work. Some types have serious restrictions either because they are toxic, or because they do not support factors such as humidity or heat. Know well what use of the object you intend to paste!
- PVA type glues are very cheap: small bottles cost around R $ 5. Always know the volume of work you will have to buy the ideal amount of glue and not suffer from shortages or waste.

How to be sure about what type of wood glue is ideal for your chores? Let’s bring down all the information so you know exactly what you need!
Whether with carpentry, crafts or home repair, you will surely make the ideal choice!
What is a wood glue and what is it for?
The glue specified as “wooden” usually serves to glue wood to wood. There are other types of glue, such as epoxy, which are used to join wood with other materials such as fabrics or metals.
Still, it is important to know how to make good use of a wood glue. Various household items, furniture and arts do not use other materials, so the glues that receive this specification end up being very useful.
The important thing is to know what your needs are. How much glue will I need? Will the object come in contact with moisture? Will it be used for meals? All of this is fundamental when it comes to choosing the best option for you!
Did you know that carpentry is one of the oldest activities of mankind? There are records of it in the Bible, for example. Knowing how to work with wood has always been an art, and even today artisans who are good with this material are valued.
In the most remote times, there was not much glue option. The most frequent was animal fat (which is still used!). But can you imagine the work between its extraction, transformation and use without any industrial aid?
What are the types of wood glue in the market?
We will focus on three main types called “wood glue” in the market: white PVA, yellow and crushing PVA (or Titebond).
The white and yellow PVA glues are very similar. Their differences are in the setting time, that is, in how long they leave the wood fully glued, and in the stains produced. The white PVA glue wins in the first aspect, while the yellow PVA wins in the second.
Both yellow and white PVA are not recommended for objects that will have contact with moisture and have a certain toxicity. Therefore, avoid using them in kitchen utensils or that need to be constantly washed.
That’s exactly where Hide Glue crushing glue (popularly called Titebond because it is the only brand found) comes in. It has resistance to moisture and is not toxic at all, making many prefer it.
Check the details of each type of glue in detail in the table below:
In addition to these three types, there are others worth mentioning:
- Epoxy glue . Very efficient, but needs manual skill and makes a lot of dirt.
- Coconut glue . Made of animal protein, but sold in tablets (unlike the Hide Glue, already ready), it is excellent for those who have patience, but has very complicated use.
- Instant glue (famous as SuperBonder). It is versatile, but toxic and restricted to types of wood.
- Shoemaker’s glue . Used in certain situations that involve the use of wood in tapestry.

How much do wood glues cost?
Wood glue prices may vary according to quantity and type. PVAs are the cheapest and easiest to find. Small bottles start from R $ 5, while 50 kg barrels can be found in the R $ 450 range.
The crushing glue is more expensive, with 473 ml bottles of the Titebond brand costing around R $ 40. Each other type of glue will also have its variations: a tube of 100 g of epoxy, for example, comes out from R $ 7.
Where to buy wood glue?
Department stores or building materials may have some types of glue, others specializing in crafts as well. The ideal is to make a good search for these places, as well as carpenters and shops specializing in wood.
If your preference is to buy over the Internet, you can find a great variety of models on Amazon. The Free Market is also a great option. And, of course, don’t forget the e-commerce specialized in the types of products mentioned in the paragraph above.
Purchasing criteria: Important factors when buying a wood glue
In addition to everything we have already mentioned, there are other factors that must be taken into account before purchase. We made a list with the most important ones:
- Glue quantity
- Shelf life
- Water resistance
- Expansion resistance
- Materials to be glued
We will explain each of them below.
We have already shown that there are glues found in small 100 ml bottles up to 50 liter vats. That is, for small domestic repairs and for constant professional services. What is your need?
You need to know what you are going to do and how much glue you will use to buy the packaging with the correct amount. That way, you will avoid wasting or having to make a new purchase because you don’t have enough for the service you need.
The validity is related to the item above: if you buy a much larger amount of glue than necessary, you will have large leftovers. And from there, it may be a long time before the date when it will no longer be useful.
A good idea if you don’t know how much glue you need is to estimate upwards. Thus, you do not need to make the second purchase in the middle of work. But if you don’t deal with the material often, the ideal thing is not to have a glue that will expire quickly and still have it when you need it.
As we mentioned in the section on types of glue, in the Buying Guide above, Titebond glue is the most suitable if the intention is to glue pieces of wood that will come into contact with water. In addition to not being toxic, its resistance to water is much higher than that of yellow and white PVA glues.
In addition to the resistance to moisture, which we have already mentioned, there is another that may be important: resistance to dilation. If the object to be glued is going to come into contact with heat (especially in pots or other utensils that go on fire), it is necessary to observe this glue characteristic.
If the glue has no resistance to swelling, the object will quickly peel off. So stay tuned if that’s your case and make the right choice!
Materials to be glued
We reiterate once again that the glues mentioned in this article serve to join wood with wood. When it comes to other materials, like metals, tapestry or plastics, it is necessary to reorganize the types that do a good job.
For tapestry, we recommend shoemaker’s glue. For most uses, epoxy does an excellent job. The performance of PVAs, depending on the material, is not very satisfactory.
