How to Use a Spray Adhesive
Using a spray adhesive is a convenient way for application. It allows for faster application and a quicker drying time. It is easier to control adhesive dispensed when using the spray gun. The gun also helps achieve accuracy, which is vital in the outcome of projects. Waste is minimal due to the controlled spraying mechanism. Spray adhesives are packaged in both large cylinders and small cans. This enables portability and ability to reposition. When using these products, it is important to follow some safety precautions.
Wear a Safety Mask
You should wear a safety mask to help you avoid the fumes from the spraying can when you are using a spray adhesive. In case there is heavy wind, the need for a safety mask is higher. It also protects the sensitive skin on your face from the adhesive spray.
Wear Eye Protection
If the spray adhesive gets in your eyes, you must rinse the area with warm water thoroughly and then seek medical attention if the irritation does not subside. To avoid such situations, it is best to wear safety goggles when you are working with spray adhesives.
You should wear thick gloves when you use a spray adhesive, which can make you move the work surface freely without afraid of getting the glue on your hands. For the same reason, it is preferable to wear long sleeved clothing. If you get some spray adhesive on your clothes, remove them and wash the skin underneath. Prolonged contact with skin can cause irritation and other skin problems.
If applied properly, spray adhesives can result in a seamless and clean item without the fuss and the mess.
Step 1 – Prepare the Work Area
Before you use a spray adhesive, you need to properly set up the area you will use. Choose a well-ventilated area to allow the fumes to circulate properly.
On a table or workbench, place newspapers, cardboard or cloth enough to cover and protect the surface. You can use any kind of material as long as it is big enough to cover the surface. Place the item to be glued on top of the covered surface.
Step 2 – Prepare the Spray Adhesive
Shake the can well before you use the spray adhesive. Never tilt the can upside down. You will notice a dot on top of the can. Use this dot to straighten the nozzle arrow of the can. Check to see if the can is working properly by doing a test spray.
Always wear your nose mask or facial mask when you are using spray adhesive. The mask prevents you from inhaling the fumes while you spray. Also, do not forget to wear your latex gloves, as they ensure the adhesive doesn’t stick to your hands.
Step 3 – Use the Spray Adhesive
You should clean the surface you want to bond to make sure the work is proper. It should be clean from any grease, dirt or moisture. You should always hold the spray adhesive upright and should maintain a distance of 6 to 8 inches between the spray and the working space. If you spray too closely, the result might be too wet of a spray, which can result in puddling.
When spraying, ensure you have a uniform coat on the surface of the items to be bonded. You can add a second coat to the surface as long as you work fast to prevent the first coat from drying. To prevent the adhesive from oozing out when you press the pieces together, refrain from spraying the adhesive all the way to the ends of the items.
Step 4 – Observe a Waiting Period
Once you are done spraying the adhesive to the item, wait for 30 seconds before you secure the items to be glued together. This gives the solvent in the adhesive time to evaporate properly.
Step 5 – Secure the Pieces Together
After the allotted waiting period, carefully bond the items together. Make sure the pieces are aligned. Once you have put the pieces together, do not move them.
If the surface shows some bubbles, apply pressure to remove them. Rress from the center and move the pressure toward the end.
