Foam Adhesive vs Spray Adhesive
Foam adhesive is useful for various construction projects. The powerful polyurethane based adhesive enables quick and lasting bonding of all sorts of materials. Also useful to the consumer is spray adhesive. This type of adhesive is dispensed in droplets. It gives both temporary, and permanent, bonding to items. Both adhesives come in handy for home decorating and household fixes. Below are the pros and cons of each.
Foam Adhesive Advantages
Foam adhesive is typically used for heavier construction jobs because it is stronger than spray adhesive. For example, installing floor boards and wall panels is better with foam adhesive. It has a long lasting efficacy which makes bonded items more durable. Foam adhesive is easy to apply. You do not need to struggle with holding the can at the correct angle as you would with spray adhesive.
Simply dispense the adhesive from the tube onto the work surface. You can generally have a cleaner work environment with this adhesive. Also, foam range adhesives are less of a threat than spray adhesives. This also makes the foam type of adhesive more convenient for those who suffer allergies.
Foam Adhesive Disadvantages
Foam adhesive disadvantages are that it is difficult to achieve even coverage. You will need to be careful to ensure the adhesive is dispensed uniformly, about 3 inches apart from top to bottom of the work surface. It becomes tricky when surfaces being worked on are very small. Dispensing a minimal, yet uniform amount, may prove difficult.
Spray Adhesive Advantages
The spraying technique is a convenient method of 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.
Spray Adhesive Disadvantages
You are required to have some degree of accuracy to evenly spray. When held horizontally, especially as the contents reduce, it results in uneven coverage. Should overspray occur while working, you’ll end up with a messy working site. If not well controlled, the spray can land on items and surfaces beyond the work area. This creates more work because of cleaning up. You need to protect the work surface and adjacent areas from overspray. Old newspapers, or some other disposable material, can be used. However, it adds to the work involved.
Trapped bubbles may rise if you don’t apply pressure correctly on the work surface. You’ll end up with a less than satisfactory job. The risk of inhalation is higher with spray adhesive than foam types. This is because of the solvent propellant involved in spray adhesives. For this reason, more caution must be exercised while using these adhesives. It is important to put on safety glasses, chemical resistant gloves and a respirator while working.
