The Pros And Cons Of Hot Melt Glues

- Advertisement -

Hot melt glues, also known as hot melt adhesives (HMA), are thermoplastic adhesives that can be used for bonding materials. They can be applied for home improvement projects, crafts, and quick repair jobs. They’re used across industries too. For instance, in the packaging industry, they’re applied to close the flaps of paperboard cartons and corrugated boxes. On the other hand, they’re used for spine gluing in the bookbinding industry and insulating a device’s components in the manufacturing industry.

To properly bond materials with HMA, you need to apply the adhesive in its liquid or molten state to one of the materials and then bring the second material in contact with the material that contains the HMA. Once the adhesive has cooled down, it will bond both materials securely.

With all these benefits, it’s no wonder that hot melt glues have become some of the most popular DIY tools in almost any industry. Whether for construction or creative purposes, their strong, stable bonding effect makes them quite a reliable and convenient product.

Cons Of Hot Melt Glues

Cons Of Hot Melt Glues

1. You Have To Prepare Surfaces Before Use 

HMA sticks quickly when drying, so you wouldn’t want it to fall on surfaces carelessly. Prepare the surface before use by covering it with bubble wrap or newspapers. You can also prep the surface using your own approach to protect exterior parts and furniture.

A helpful tip is to use machinery like glue guns. This will reduce the number of mistakes made during your project.

2. You Have To Work Quickly 

Hot melt glues dry fast, so you must work as quickly as you can to ensure the materials get bonded. To address this issue, you can use a glue gun and activate it when you’re ready to use it.

Hot Melt Glue Guns

When applying hot melt glues, take advantage of hot melt glue guns since they prevent you from leaving a mess on the surface you’re working on. Hot melt glue guns also help you work at your own pace, whether it’s for a home improvement project or a new jewelry line. If you don’t have the budget to get a hot melt glue gun, you should go for products that come with their application, like a small brush or an industrial tincture.

Materials That Don’t Work Well With Hot Melt Glues

Some materials won’t work well with hot melt glues. For example, materials with smooth surfaces, such as vinyl, metal, or wet and greasy places, are harder to bond. So, when working with hot melt glue, check all your equipment. There should be no cracks in your hot melt glue gun. If there are cracks you fail to notice, your task will only turn out messier than it should be.

As an extra precaution, make sure you wear some protective gear, like goggles or gloves. It’s important to protect your eyes always during any construction or creative project. Remember to follow all the directions that come with your hot melt glue product for the best results.


Hot melt glues are convenient for home improvement or other hands-on projects and are widely used in various industries. But they can destroy your furniture and cause injuries if you don’t take the necessary steps to protect surfaces and wear safety gear.
