Care Instructions for Neoprene Bonded Sponge Waterproof Wetsuit Fabric

Washing Tips

  • Hand wash only using cold water to maintain the fabric’s waterproof properties.
  • Use a mild detergent (preferably designed for wetsuits or delicate fabrics).
  • Do not soak for long periods—quickly rinse after submerging.
  • Avoid bleach, fabric softeners, or harsh chemicals, as they can degrade the neoprene and sponge layers.
  • After use in saltwater or chlorine, rinse thoroughly with fresh water to prevent breakdown of the material.

Drying Tips

  • Lay flat to dry in a well-ventilated area, away from direct sunlight.
  • Do not use a dryer, as heat can cause the fabric to lose elasticity and waterproofing.
  • Avoid hangers, as they may stretch the material—if hanging, use a thick, padded hanger.
  • Flip the fabric inside out halfway through drying to ensure even drying and prevent stiffness.

Temperature Tips

  • Never expose to high heat—hot water, dryers, or direct heat sources can damage the sponge layer and waterproof coating.
  • Wash in cold water only to preserve the fabric’s flexibility and durability.

Ironing Tips

  • Do not iron or steam, as heat can damage the neoprene and bonded layers.
  • If wrinkles form, hang the fabric in a steamy bathroom to let the creases relax naturally.

I don’t think I got sent the right fabric?

I have in front of me techno neoprene despite buying 3mmm foam neoprene. I can tell because it has the strings and not the foam. Are they the same in the system? I’ve already been using it in a project but beware that this is not as listed.

Inconsistent Thickness Abound

After having ordered many times from Big Z Fabric we can no longer purchase from them. The consistency in which there thicknesses varies is far too great. Anywhere from 50-75% difference in thickness is unacceptable. When ordering neoprene that is sold in thicknesses you should not receive a material that is 1.8mm when ordering 1mm. I understand tolerances and variances but almost double the thickness is unacceptable. This has happened on the thicker materials as well. We ordered 4mm neoprene and received neoprene that was 3.2mm. If they could figure out the QC as well as fulfill the orders quicker then BigZ would be a reputable supplier.
