Glue and epoxy are types of adhesives I normally use when undertaking a home DIY project.
I like them as they are efficient and provide me with a strong bond, regardless of where I use them.
Their multipurpose nature is among the top reasons I recommend them for use in all kinds of home improvements.
But you are probably wondering what the differences are between glue and epoxy, their pros and cons, and which one ranks better than the other.
I will look at all these details below.
Epoxy is a shorter name for polyepoxide, a versatile and robust form of adhesive.
It’s one of those glues that can be used in commercial settings and DIY home projects
The glue is manufactured by combining two primary ingredients: a hardener and epoxy resin.
• Strong: It’s among the strongest adhesives available in the market today. Its strength level will vary depending on the ratio of epoxy resin (see how to colour epoxy resin with acrylic paint) to hardener used in its preparation.
• Waterproof: One of the reasons I like using it in my home improvements is that it’s waterproof. I don’t have to worry about the object I have glued getting wet.
• Safety Issues: solid epoxy resin is harmless, but the liquid versions can irritate your skin and eyes.
• Preparation Difficulties: It takes a bit of skill for you to prepare it at home. I recommend working with a professional to ensure you combine the ingredients properly.
I am sure you have already come across glue at one point or the other. It’s by far the most popular adhesive globally and one that comes in different varieties.
My research has shown that it’s a cyanoacrylate compound that uses exothermic reactions to attach two surfaces.
• Instant Bond: Cyanoacrylate compounds can create a bond between the surfaces being attached in an instant.
• Can Be Used with Non-Porous Items: It works best when used on items made from paper, metal, wood, glass, and even stone.
• Safety Issues: The exothermic reactions are good for the application speed, but they can result in serious accidents if one is not careful.
• Material Limitation: I have found that you can’t use glue with fibrous materials or fabrics like leather, wool, and cotton. Using it on such items can lead to severe burns.
Differences Between Epoxy and Glue
Having explained what these adhesives are and the pros and cons of each, I think it’s now time to look at their differences.
For this, I will need to use a table…
Epoxy has tremendous structural strength and is best used for filling spaces between parts.
It has very low shear strength. The items you have bonded can resist direct pulling, but they can’t do so for off-angle stress.
I have used it as an adhesive, a coating for metal, and even as insulation for some of my electronics.
Its functions are a bit limited and include small parts assembly and wood finish in home improvements
You can use white vinegar or acetone to remove it before it hardens.
It’s removable using acetone or GBL (gamma-butyrolactone)
Glue vs Epoxy, Which Is Better?
While both adhesives are efficient and easy to find, I strongly recommend glue as being better for all DIY home improvements.
It can be used with almost all materials, is instantaneous, and is easy to clean.
Epoxy adhesives are best left for commercial applications due to the work that goes into creating the perfect blend.
- Strong, permanent, fast and gap-filling; Great for multiple surface applications
- Best for tough repairs requiring a durable bond, gap-filling and solvent resistance
- Dries clear; Ideal for clean, easy finishing
- 5 minute set; Plenty of repositioning time for the perfect fit
- Easy-to-Use Syringe; Separate barrels of resin and hardener keep epoxy from hardening, plus syringe dispenses evenly and includes a cap for multiple uses
- Easy-to-use self-mixing dispenser and precision applicator
- High-strength formula bonds wood, metal, tile, ceramic, glass, plastic and more
- Waterproof, sand able and paintable
- It can be used as an adhesive for a wide range of materials or as a versatile filler for gap bonding, surface repairs and laminating.
- Loctite Epoxy Instant Mix 5 Minute does not shrink and is resistant to water and most common solvents.
- Clear epoxy adhesive liquid bonds wood, metal, glass, ceramic, concrete, and fabric
- When mixed it turns opaque initially then clear to full cure to blend in with bonded material
- Continuous service temperature range from -20 to +200 degrees F
- Provides work time of approximately 4 minutes, cure time for function of 1 hour, and full cure time of 24 hours
- Forms tough bond for durability
- J-B Weld ClearWeld: A clear, quick setting and multipurpose two part epoxy that provides a strong and lasting bond on surfaces including metal, tile, most plastics, ceramic, glass, wood and more. J-B Weld ClearWeld comes in a syringe allowing for an easy 1:1 mix ratio. The unique syringe has a re-sealable cap that prevents drying out and leaking, allowing for multiple uses
- Cure and Set Time: After mixing the two part formula with the included mixing tray and stir stick, ClearWeld takes 5 minutes to set and 1 hour to cure. J-B Weld ClearWeld set and cure color is clear.
- Strength: J-B Weld ClearWeld has tensile strength of 3900 PSI.
