What Actually Is Wood Glue?
Wood glue is an adherent used to join two pieces of wood; it seems like a simple concept, but it is the backbone of many projects, and no wooden project can be completed without this. Wood glues can be used in all projects, from small DIY projects to large construction projects. Before attaching screws or bolts, liquid adhesives are the primary substrate that acts as a holding agent.
Not only one kind of wood glues are there, but separate adhesives are for indoor and outdoor details. The level of support and binding each glue provides is also different and entirely depends on its quality. If you mistakenly choose a wrong adhesive that does not strengthen enough, most of the woods won’t work with that, and you can suffer badly. Usually, wood glues are available in the gallons; it helps to transport it safe and sound.
Types of Wood Glue:
Majorly five different types of glues are there that you must know before selecting an adhesive for your project. So let’s dive into each of these types.
1. PVA Glue:
PVA glue, also known as Polyvinyl Acetate, is non-toxic, water-soluble, and use specifically for non-structural wood to wood bonding. This inexpensive adhesive is commonly found in the homes, and it can easily clean with water. It comes in two varieties- white and yellow, white PVA is for indoor use, and yellow PVA is for outdoor use. This adhesive is water-resistant, and this feature is mainly because of the cross-linking of the glue.
The only drawback of this glue is that it will leave behind dried bits; the residue left spoils the wood’s overall finish. This problem can be solved by wiping off the excessive glue.
2. Polyurethane Wood Glue:
One of the strongest wood glue is Polyurethane glue as it of high strength and creates tight and lasting bonds. In all significant wood glues, the principal ingredient is Polyurethane, and it can use for a variety of things. It is a moisture activated, and it creates a reliable bond on a wet surface when the adhesive dries, then it is easy to paint the body that gives a finishing look. It also has waterproofing ability that makes it excellent for both indoor and outdoor projects. This glue can toxic, so you need to handle this with a lot of care.
3. Cyanoacrylate (CA) Wood Glue:
Cyanoacrylate is a glue used to join two hard pieces, and the bond is rigid and strong. The temporary bonds are usually created through this super glue as it sets and dries quickly, so you need to be very careful while working through it. CA glue best works when the wood is damp and adhesive is placed at room temperature.
4. Epoxy-Based Glue:
Epoxy is the best glue that is used for filling up the gaps and cracks. This glue is a two-part formula, mainly consisting of hardener and a resin that combine works miraculously to strengthen the bond. It takes some time to make a bond, and it only works on a dry and clean surface. Titebond III Ultimate Wood Glue is also epoxy glue used for application on both indoors and outdoors.
5. Hide Glue:
As the name suggests, the hide glue is derived from the animal hides and is entirely natural; this makes it an excellent choice. The hide glue comes in two versions- solid and liquid. Liquid glue takes some time to work while solid glue cools quickly after the application, and both of these have their functions. It has an aesthetically pleasing effect on furniture.
List of PVC Glues:
1. Polyvinyl Acetate:
You name a thing that you want to do at your home with the glue, and PVA is here. This adhesive is acid-free and is used for non-structural carpenter glue. It is described as Titebond II type adhesive and is water-resistant.
2. PVA Wood Glue:
PVA wood glue is mainly used for woodworking; another name of this is aliphatic resin. This helps to strengthen wood to wood bond and serves as an excellent wood adhesive as it ensures to prevent movements. Top examples of this are Titbond Original Wood Glue and Titebond Quick And Thick.
3. PVA Water Resistant Glue:
As the name indicates, this glue is designed to absorb moisture as it can adapt to all weather conditions. The two most important benefits of this water-resistant glue are- moisture tolerance and mildew resistance. This adhesive works great for Titebond II and III types.
4. White Glue vs. Yellow Glue:
White glue is useful in hobbies like book-binding, card making, or doing crafts indoors, as it is easy to clean and dries quickly within 30 minutes. In contrast, yellow glue is preferred for outdoor activities. It is firmer and holds tightly than water glue.
Tips for Using Wood Glue:
- Before purchasing a wood glue, make sure to carefully notice the expiry date as they lose their binding ability after the time, and usually, their shelf life is no longer than one year.
- While working with the glue, always wear gloves as it may stick to your skin that is quite irritating.
- Always keep your glue at room temperature, chill, or hot climate; both can affect the glue’s consistency and viscosity.
- After using glue, don’t forget to clean the nozzle every time; otherwise, the adhesive may clog there, and it would be challenging to take it out.
Woodworkers have used wood glues for a long time, and all of the types have their specifications with separate functions to perform. Considering all the factors, we came out with the conclusion that Polyurethane Wood Glue is the strongest glue that ensures firm and lasting bonds than others.
