Spray adhesives are contact adhesives applied in a liquid form and then quickly dried to a solid.
They are available as both aerosol cans and pump-action bottles.
Spray adhesives provide a strong, permanent bond between two surfaces. It can be used on a variety of materials, including metal, plastic, wood, and paper.
The main advantage of using spray adhesives over regular ones is that they are quick and easy to use.
They can be applied in a thin coat, so there is no need to worry about excessive mess or waste.
Spray adhesives also have a high bonding strength, making them ideal for heavy-duty applications.
Most of them are extremely easy to use and can be applied to surfaces with an aerosol can.
The cans are filled with a mixture of chemicals, propellants, and the desired adhesive, which is then sprayed into the air where it covers the surface you desire to bond together.
How To Apply Spray Adhesive?
The application of spray adhesive is very easy and can be done in a few simple steps:
Clean the surfaces to be bonded with a solvent, such as acetone or denatured alcohol.
This will remove any oils or dirt that may interfere with the adhesive bond.
Shake the aerosol can well and hold it 6 inches or more from the surface to be bonded.
Apply a thin, even coat of spray adhesive to one surface and allow it to dry for 10 minutes before applying it to another surface.
Keep in mind that you must use the proper amount of pressure on both surfaces when bonding them together.
Too much pressure will not help with adhering, and too little pressure can cause the adhesive to not bond correctly.
Apply pressure to the surfaces for 30 seconds to 1 minute and allow them to dry for 24 hours.
After this, the bond will be complete, and the surfaces will be permanently attached.
How to Remove Spray Adhesive?
If you need to remove excess spray adhesive from a surface, there are a few methods that can be used.
Some of the common ones you can use are:
1. Soak the surface in acetone or another solvent until the adhesive loosens and can be removed.
2. Use a heat gun or blowtorch to heat the adhesive until it softens and can be removed.
3. Use a scraper or chisel to chip away at the adhesive until it is removed.
4. Apply a liquid adhesive remover to the surface and allow it to soak in for 10-15 minutes. The adhesive will then loosen and can be wiped away.
5. Apply a paint and varnish remover to the adhesive and allow it to soak in for 30 minutes or more until the adhesive can be removed.
6. Use a soft cloth and mineral spirits to remove the adhesive.
7. Grate the surface of the object where the adhesive is using a cheese grater or other hard, fine-toothed grater.
8. Soak the surface in denatured alcohol until the adhesive loosens and can be removed.
Few Drawbacks of Using Spray Adhesive
Although spray adhesives work great for any surface, there are a few drawbacks to using them that you should keep in mind.
1. The fumes from the adhesive can be dangerous and should not be inhaled.
So, you need to always work in a well-ventilated area and wear a respirator when using spray adhesive.
2. The adhesive can be messy and difficult to clean up.
So, make sure to cover any surfaces before beginning work and to use a drop cloth when applying the adhesive.
3. The drying time can be long, depending on the thickness of the adhesive coat.
So make sure you give it enough time before applying another layer or using the surface.
4. When the adhesive is applied in a thick coat or if too much pressure is used during application, the surfaces to be bonded may be damaged.
It is important that the adhesive only covers the desired surface and that it does not create a thicker layer than what was intended.
Despite these few drawbacks, spray adhesive is an extremely versatile and easy-to-use adhesive that can be used for a variety of applications.
When used correctly, it creates a strong bond that will hold up under pressure.
