The Secret Weapon – Why Epoxy Beats Wood Glue Every Time Guide to Epoxy vs Wood Glue
Updated: 17 Jul 2023
In the world of woodworking, it is always overwhelming choosing the right adhesive for the success of your DIY project or a carpenter’s work. Because, when it comes to binding two pieces of wood together, you need to pick one from epoxy vs wood glue. Both adhesives are commonly used for DIY and professional projects and have their unique properties and application.
Imagine spending hours meticulously crafting a wooden masterpiece, only to have it fall apart due to a subpar adhesive. Choosing adhesive is not taken lightly, because it had a direct effect on the structure and the durability of your unique and artistic design.
In this blog, we should review and explore wood glue vs epoxy, their characteristic, strength, weaknesses, and ideal uses. This guide will increase your knowledge to make an informed decision to choose adhesive wisely.
What is epoxy?
Epoxy gained immense popularity due to it being widely used in various industries like DIY projects, woodworking, construction, manufacturing, and automotive. It is mostly known due to its durability, strength, and versatility of its uses for every material.
One main characteristic of epoxy is its bond strength. It makes a strong bond and secures a long-lasting connection between the two materials on which it uses. Woodworking chooses this if maximum strength requires. Heavy and Bigger wood pieces are also combined with the epoxy adhesive that lasts for a long and dries quickly.
Another epoxy advantage it fills the gaps while jointing the pieces with others. It has low viscosity and easily fill the gaps where no other adhesive reach. Resin verse wood glue fills the gaps in irregular shapes and structures.
Strength and Weakness:
Epoxy offers various strengths verse wood that makes it easy to use in various applications:
- Durability and longevity
- Superior bonding strength
- Sealing Gaps
- Stronger Bond
- Use for Resin Flooring as well
With its numerous strength, resin has some drawbacks:
- Curing time
- Toxicity and safety precautions
- Bubbles while curing
What is Wood Glue?
Wood glue, also known as carpenter’s glue or woodworking adhesive, is a specially formulated adhesive designed for bonding wood surfaces together. It is also called hot glue or hide glue. It is a popular choice among woodworkers due to its ease of use, affordability, and reliable bonding properties.
Wood glue vs epoxy is made with polymers, resin, and some additives it is typically a water-based glue. These glue are commonly used for small woodworking areas and their composition vary according to the brand and type of glue we use.
Wood glues have low viscosity and are used for easy application and spreading. It comes in liquid form and is spread with a roller or brush or any soft spreader by direct application.
Epoxy vs Wood glue penetrates the wood fiber and makes a bond with them for durability and strong ability.
Strength and Weakness:
Wood glue has several strengths that make it a popular choice for woodworkers:
- Easy to use
- Non-toxic and easy to use
- Alternative wood bounding
- Easy to remove from all surface
With its strength it also offers some laminations:
- Limited ability to fill the gaps
- Slow curing time
- Less ability to water resistant
Difference between Epoxy vs Wood Glue:
Although resin vs wood glue are used to make bonds with different things some differences are:
Epoxy is stronger than glue and another adhesive. Epoxy adhesive uses wood pieces to stay longer and made a strong bond. Because it fills the gaps between the woods and makes a strong chemical bond.
On the other hand, wood glue does not make a strong durable bond with heavy and large wood because it is a water solvent glue. It makes strong bonds for weaker or small pieces of wood.
Resin composition and strong bounding with any metal, glass, fabric, and steel make them famous. On the other hand wood glue just bond some wood and plastic-type products.
Epoxies are more durable they stay with heat, water, moisture, and chemical than wood glue. These are resistant to slip and stain as well, but wood glue is not resistant to stain and slip.
The wood glues are more durable than softwood and plastic because the water surface holds them tightly. But with metal and glass epoxy are more durable and commonly use.
Wood glues are polymers called hide glue but it less resistant to water. The glue easily solves in water and makes the surface again ready to break. Even a small amount of water damage the glue surface.
Resins are more water and solvent resistant. It does not allow any water or solvent to disturb epoxies surface. Epoxy is resistant to water and moisture and makes the surface durable for a long.
Epoxy is made with the chemical formula of resin and hardeners which make it more expensive than glue. In epoxies, more components are used to make them durable and long-lasting surfaces.
Wood glues are made with polymer and some additives make them less expensive. But some of its applications are more expensive than epoxy that are quick-dryer.
Epoxy cure quickly while uses. You need to pure the exact amount of epoxy to use because it starts curing once it is ready to use on the surface.
Wood glue is water-type glue and takes much more time to cure than epoxy or adhesive. The curing time also depends upon its durability and the surface on which we use it.
Frequently Asked Questions:
Is epoxy stronger than wood glue?
Yes, epoxies are stronger than glue and other adhesive. The chemical bond with other surfaces like wood, plastic, and flooring makes them stronger than other adhesives.
Can epoxy be used as wood glue?
Wood glue epoxy is used by professional and DIY workers for the durability of projects. The best epoxy glue for wood also gives a long-lasting surface for use. It creates a water-resistant surface for every surface you use.
Why use epoxy resin instead of glue?
Epoxy makes a strong chemical bond with any material we use it on. It also fills the gaps even on unregular surfaces. Epoxy gives thickness and strong ability to surfaces. We also use epoxy if wood and surface have more interaction with water.
Does resin stick wood to wood?
Yes, the resin is sticky on all surfaces. The epoxy stick from wood to wood and make a strong durable bond for longer use.
How long do epoxies on wood last?
Epoxies are known for their durability and long-lasting life span. It typically lasts on any wood for 15 to 20 years with proper maintenance and care.
Does resin make wood waterproof?
Yes, epoxy makes wood waterproof if it uses properly and on the entire wood. It also makes other surfaces water-resistant like floors, and countertops.
Does resin bleed into wood?
Yes, epoxy bleeds into woods. But if you apply a sealer and base coat on the wood then it does not bleed to the wood.
Choosing between epoxy and wood glue can greatly impact the success and longevity of your woodworking projects. Both adhesives have their unique properties, strengths, and weaknesses that make them suitable for different applications.
Epoxy with two components system makes a durable, long-lasting chemical bond to make surface water-proof. Its chemical bond makes every surface slip and stain resistant. Epoxy easily fills the gaps in the wood and allows it to stay longer with other parts.
Wood glue vs resin is a polymer and also called hot glue makes a temporary bond with other surfaces except for wood or plastic. Some softwood or plastic do not make a well bond with epoxy because they are less durable with it.
In the end, Epoxy and wood adhesive are used according to the material we are working on it and the curing time we need to complete the projects. Some project needs more curing time and the use of epoxy on it makes them less durable.
