As in the name, an adhesive spray is a type of typical glue that comes in an aerosol canister and is sprayed onto surfaces to bond them together.
Sprayable adhesives are different from traditional white glue because they are mostly water-based and will soak deeply into the material being glued to create a stronger bond that lasts for a long.
The adhesive spray is typically used for bonding wood, paper, vinyl, and fabric for numerous projects such as:
- School projects
- Patching up old clothes
- Mending leather bags and upholstery
- Repairing wooden or plastic furniture at home
Spray adhesives will generally work well for everyday DIY fixes around the home decorations, along with arts and crafts projects. Some of them can also work for construction applications like gluing drywall and ceiling inserts.
But for more demanding and heavy-duty jobs that require bonding of heavier materials, attaching load-bearing items, bonds exposed to extreme temperatures, etc., spray adhesives might not be the best solution.
How to Use an Adhesive Spray?
An adhesive spray is straightforward – simply point and spray onto the desired surface.
- It’s important to start by ensuring that both surfaces are clean and free of any dirt or debris before spraying. Otherwise, the glue will not adhere properly.
- Once cleaned, spray the adhesive, evenly covering the entire surface area you want to be bonded together.
- After the adhesive spray is applied, press the two surfaces together and hold for a few seconds until dry.
For best results, it’s recommended to let the bond cure for 24 hours before using or moving the glued item.
Spray adhesive usually takes about 15-20 seconds to become tacky, but check the canister’s label for specific drying times, which may alter depending on the brand or type of glue.
Pros and Cons of Using an Adhesive Spray
Huge benefits are offered by using adhesive sprays over other types of traditional glues, which is why it has become such a popular choice among DIYers and crafters.
Some advantages of using spray adhesives include the following:
1- Bonds Quickly and Easily
Spray adhesives (no matter what surface you use) will dry quickly, making them ideal for promptly bonding two surfaces together.
If you are on a tight timeline or working with materials that cannot be left wet for too long, an adhesive spray is a way to go.
2- Dries Clear and Mess-Free
Another great thing about spray adhesives is that they will usually dry clear, so you don’t have to worry about any ugly residue left behind.
They are also mess-free since the glue comes out in a fine mist, making it easy to control and avoiding any unwanted adhesive buildup.
3- Provides a Strong and Lasting Bond
An adhesive spray can create a powerful, long-lasting bond between two surfaces when used correctly. This is especially beneficial when working with heavier materials, such as wood or metal, that need to be firmly attached.
But mind it, as I said before, avoid using sprayable adhesives for heavy-duty projects like the ones under force or shear stress.
4- Flexible and Can be Repositioned
Another advantage of using an adhesive spray is that it is usually quite flexible, meaning that you can gently move or adjust items after they’ve been glued together.
This comes in handy for projects if you need to make any last-minute changes or corrections, and it can also help bond two irregularly shaped surfaces together.
5- Easy to Use and Store
Another big selling point of adhesive spray is that it is effortless to use – simply point and spray onto the desired surface. And you are ready to attach two objects.
The adhesive is also easy to store since it comes in a canister that can be kept in a cupboard or drawer until needed.
6- Waterproof and Heat Resistant
I appreciate the waterproof and heat-resistant properties of adhesive aerosol sprays, which makes them suitable for bonding materials that will encounter moisture or heat.
However, it’s crucial to avoid using them on surfaces exposed to high heat continuously. These sprays cannot endure extreme temperatures for an extended period and may deteriorate.
7- Can be Found at Most Craft Stores
Last and not least, if you are on a strict deadline and need to get an adhesive spray for a DIY project that requires quick finishing, you can easily find them at most craft stores or online, like Amazon and Home Depot, where they allow you to compare different brands and options before making a choice.
On the downside, there are a few disadvantages to be aware of before using an adhesive spray.
- Sprayable adhesives can be flammable and more expensive than other types of glue .
- The fumes can be toxic and cause respiratory problems if not used in a well-ventilated area.
- If not applied correctly, the glue can cause warping or staining after it’s dried.
- Also, the spray adhesives are not designed for industrial applications like attaching heavy loads or surfaces under pressure.
- Above all, it’s not an eco-friendly product and can be difficult to remove if you plan to recycle or reuse materials.
What is the Strongest Spray Adhesive on the Market?
Well, there is no best or strongest adhesive spray on the market since it really depends on what you’ll be using it for.
If you need an adhesive spray for something like crafting, then any general-purpose glue will do just fine. But if you need a stronger bond for heavier materials like wood or metal, you’ll want to look for an industrial-strength glue.
Some of the most popular brands of adhesive sprays I have worked with include 3M Super 77 and GORILLA Heavy Duty Spray Glue. I have used them for a variety of projects, and they have never failed me yet.
I have also heard good things about Loctite’s adhesive spray products, but I have not personally used them before.
All these spray adhesives offer high-strength bonding, but in my opinion, the 3M Super 77 can be considered to be the strongest on the market. It is a versatile, all-purpose adhesive that can bond together a wide range of materials like paper, cardboard, fabric, and plastics.
If you need a substitute – 3M, Rubber And Vinyl 80 Spray Adhesive is a good one. It’s specially formulated for bonding rubber and vinyl to metal, glass, wood, and plastic.
Choosing the Right Spray Adhesive for Your Specific Project
Since there are tons of different spray adhesive brands on the market, each with its unique benefits and drawbacks, it’s essential to select the best one for the job at hand.
Here are some crucial factors for you to keep in mind when making your selection:
a) Intended use – First and foremost, you need to think about what you will be using the adhesive spray for.
Are you bonding two pieces of fabric together? Attaching a poster to a wall? Applying a decal to a car?
The intended use and type of surfaces you’re working with will help you narrow down your options and choose the best spray adhesive for the job.
b) Drying time – There are many adhesives that dry very quickly, while others take a bit longer.
Think about how long you have to work with the adhesive and choose one that will give you enough time to position the surfaces before it dries. longer.
c) Strength – Spray adhesives’ bond can vary significantly based on the brand you pick.
Some spray adhesives are stronger than others, so if you’re working with heavier materials or need a very strong bond, be sure to choose an adhesive that can provide it.
d) Price – Of course, price is always a consideration when choosing any product, but it should not compromise your project.
Adhesive spray ranges in price from around $5 to $20 per can, so choose one that fits your budget and needs.
Can you spray paint over the adhesive?
It is not advised to spray paint over any kind of surface which has adhesive. The coat would not stick to such a surface and might peel off quickly.
If you still need to, you can use a solvent like acetone or alcohol to remove the adhesive first and then add a coating of primer to enhance paint adhesion.
Will using adhesive spray on walls damage them?
When used properly, adhesive sprays typically won’t harm walls. They can be especially handy for hanging light items like posters without causing any damage or leaving residue.
However, it’s important to carefully read and follow the can’s instructions, and be sure to remove any unused adhesive before it dries.
What is the difference between an adhesive and a sealant?
To clarify, adhesives are substances that join two surfaces, while sealants are substances that fill gaps and seal areas.
When selecting which to use for a project, their specific purposes should be considered. While a spray adhesive can be used in place of a sealant in an emergency, it is not recommended as it is less resilient compared to an actual sealant.
