How to Glue Foam Together
To create your custom-size cushion, you may need to glue two pieces of foam together. This is a relatively easy task and these steps will show you how to do it easily.
Supplies Needed to Complete This Task
You will need the sections of cut-to-size cushion foam that will be glued together and spray adhesive.
Preparation
Your work surface may get misted with adhesive residue during this process. While most surfaces should be able to be cleaned after the cushions are completed, some surfaces may be easier to clean than others. If you are concerned about damage to your work surface, cover it with newspaper, a drop cloth or tarps for protection.
Applying Glue to a Small Piece of Foam
Place the two pieces of cushion foam that need to be glued on top of each other, with the sides to be adhered facing outward, as shown to the lower left. Liberally apply adhesive, coating both pieces and allow about 10 seconds for the glue to become tacky.
Bonding the Foam Together
Carefully align the smaller foam section with the larger, as shown in the center picture. Once they are arranged, compress the two pieces together, starting at one end to ensure the sections will match up. Apply pressure firmly without squeezing the cushion so that both surfaces bond evenly to the other as shown at the lower right. Hold each compression for a few seconds to give the adhesive time to bond. Wait about five minutes for the glue to fully dry before moving on to the next step.
Bonding Larger Sections of Foam Together
Some cushions may be too large to simply squeeze together while gluing. For this reason, there is a different gluing method for larger sections.
Applying Glue to a Large Piece of Foam
Place the two pieces of cushion foam that need to be glued on top of each other, with the sides to be adhered facing outward, as shown to the lower left. Liberally apply adhesive, coating both pieces and allow about 10 seconds for the glue to become tacky.
Bonding the Foam Together
Align the smaller piece to the larger, joining them together as shown in the center picture. Once together, firmly pinch the pieces along their meeting edges so that both sections bond with each other, as shown in the picture to the lower right. Apply firm pressure along the entire section of foam, holding for a few seconds with each press. After adhering the pieces, give the glue about five minutes to dry before using the product.
