Wood has, over the years, earned a strong reputation as a unique building material due to its natural tones and grain patterns. Also, wood is relatively easy to build with because of its porous and soft surface, making it easy to screw or glue and join pieces using nails.
Usually, properly joining wood involves fasteners, which means that you will apply some wood glue between the wood pieces before you screw them together to create a perfect bond. As you search for your next repair project or woodwork, you need to focus on the type of wood glue you select closely.
Note that all wood glue is not the same, and making the right choice will give you the most vital bond while preserving the sheen and integrity of your wood's finish and giving you the strongest possible bond. In this guide, we will explore all you need to know before you buy wood glue.
Knowing what to look for while scouting for the best wood glues will save you the stress of trial and error. In this guide, we will explore some tips on choosing the best wood glues out there; keep reading!
How to select the correct wood glue
The first thing you should consider when buying this glue is its composition in terms of the bonding agents and chemical variants that make up the bonding system of the adhesive. Also, note that the bond could either be yellow or white, which can make all the difference in the appearance of the wood grain. The glue can be gotten in diverse adhesive strengths and viscosity.
While searching for the correct type of wood glue, the primary thing to consider is the chemical bonding agent that constitutes the glue's bonding system.
Type of wood glue
Knowing the different types of wood glue will help you refine your search. Here are the five major types of glue:
1. Cyanoacrylate (CA) Wood glue
This glue is used mainly for bonding two rigid pieces of materials, and it is the best choice for easy and quick repairs because it sets or cures quickly. The moment the glue becomes dry, it forms a complex plastic-like bond. But when it is applied, the adhesive may become messy and runny. Also, the fact that it has industrial-grade bonding power means you need to be careful not to get the glue on your hands or fingers because it can instantly bond your skin.
2. PVA GLUE
Polyvinyl Acetate is one of the most common glues found in the home. This glue is quite affordable and quite effective for basic indoor projects. The adhesive is non-toxic and can be easily cleaned using water. Some glues come with cross-linking polyvinyl acetate, which increases the water-resistance level of the bond. Thus, you can use it for different outdoor woodwork functions.
3. Epoxy-based glue
This type of glue uses a dual bonding system, the hardener and resin, specially designed to fill gaps in hardwood and softwoods. Also, it works appropriately for bonding two pieces of wood together. But it takes some time for them to get bonded. Also, you will need to have the wood clamped down to create a better bond. Even though some epoxy woods are explicitly made for indoor use, but some glues are water-resistant and can be used for outdoor and indoor services.
4. Hide glue
Hide glue is a product of animal hide, while some hide glues are made as a solid substance, and they need to be applied in the form of a reliable sense using a brush. Some glues come in liquid form inside an applicator bottle. This type of glue may be used in repairing antique furniture repair and can create a unique crackling effect.
5. Polyurethane Wood Glue
This glue ranks as one of the most durable and most robust glue types out there. Also, it is pretty versatile and can be used for several materials such as plastic, wood, ceramic, metal and concrete. This glue can be used for natural wood and softwoods because of its strength. However, it would help if you remembered that you need to get the surface wet while using polyurethane wood glues before you apply it.
Tips for using your wood glue
When you have bought your new wood glue product, always remember that most glues come with a shelf life of one year and may begin to lose their bonding potency upon the expiration of the time. Note that certain glues come with a longer shelf life of up to 2 years.
If you want to prevent the nozzle from clogging the glue, ensure you clean the nozzle upon each use.
In addition, ensure you constantly wear gloves when you are using polyurethane glues. It can be tricky getting the adhesives off your fingers.
Furthermore, if the glue gets stuck on your fingers, ensure you consult the instructions at the rear of the product on which way to remove the glue.
Tips to consider before buying wood glue
Here are a few things to consider before you buy wood glue:
One of the core factors to consider before you buy glue is the type of project you want to embark upon before you buy it. Knowing this will assist you in determining the strength you should aim for. If you are looking to glue heavy-duty items, you shouldn't go for glue lacking in force because it will chip away with time.
You certainly won't want to buy glue only for it to get dried up before you use it due to its short shelf life. If you need wood glue you can use in the future, you will have to buy a bond with a longer shelf life.
You will find glues that have lids on their bottles which help prevent air from gaining entrance.
If you select an adhesive for your project, you will need to consider the glue's dry time. In a case where the bond takes a long time to become dehydrated, it may damage your project and even make it hard for you to complete the project in good time.
Certain wood adhesives work pretty fast, which means they will become dry in seconds after they are applied.
While you are using glue for your carpentry, you should make sure that you use an adhesive that comes with natural wood color to blend incorrectly.
