Comparison

Flexible fabric adhesive vs Contact adhesive: which should you use?

Both bond soft materials. One stays soft through washing, the other goes hard and stays put.

The short answer

Fabric adhesive on anything that will be worn, washed or needs to drape. Contact adhesive on leather, rubber and heavy materials where stiffness is acceptable.

Choose Contact adhesive when

Clothing, upholstery fabric, anything laundered. The bond must flex and stretch with the material. A hard glue line would be felt or would crack.

Choose Flexible fabric adhesive when

Leather, rubber sheet, heavy canvas, foam to board. The bond must carry real load. Stiffness is fine or even helpful.

What actually separates them

Fabric adhesives are formulated to stay elastic and survive washing, at the cost of strength. Contact adhesive is much stronger and dries firm, which is fine on a shoe sole and wrong on a shirt. The deciding question is whether the finished item has to move.
