You can seam latex using glue, not by sewing. Sewing is ineffective for latex because the stitches will ruin the fabric, and the thread used will not be stretchy enough. Making a seam on latex is not similar to creating a seam on ordinary fabrics where you sew the same side of the fabric together. With latex, your fabrics must overlap when you glue them together. It is important that you have to glue the seams on top of each other because it results in a stronger bond. If you glue the seams in the same way you sew clothing, you have a higher risk of breaking the seam. Here are a few tips you should keep in mind to seam latex successfully. The seam area has to be cleaned first with acetone or mineral spirit using a piece of cloth. It would be best to work in an area where there is good ventilation as you will encounter fumes from the solvents you are going to use to clean the seam area. If you notice curling on the seam area after cleaning it, do not panic. It is an essential part of the process. Your latex will flatten once the cleaning agent dries. With latex, seams are overlapped and not sewn with the right sides together. So, you need to apply a coat of glue on top of the wrong side of the fabric and another coat of glue underneath the right side of the latex fabric. Your adhesive must be around 1cm wide on each piece. Wait for the glue to dry up. Carefully stick the two pieces together. Then, use a roller to apply more pressure to secure the bond. A great hack to remove the extra glue bits is to sprinkle the seams with talcum powder. Clear off the powder with the hardened glue bits. You can also try if the rubber cement eraser can help remove glue residue from your latex fabric. Pull both sides to make sure that your latex fabrics are excellently bonded. For gluing curved latex seams, place the pieces together slowly first. Push your finger down in the center then, slowly push along the curve. Once you reach the end, press down on the latex some more. Let it sit for a couple of hours or a day. Then, pull on the latex pieces to make sure both sides are securely bonded.
