Hydrophobic coating – “impregnation” for the PUL material

100 ml


Have you ever leaked a diaper, despite the correct application and careful selection of absorbency? Would you like a few diapers from your beloved pile to be safe with which you can leave your little one in the care of someone else without fear of leaks? Are there any minor membrane defects in your nappies? Did your favorite diapers lose their factory impregnation? Or maybe you just like additional PUL impregnation? Are you fed up with heavy-to-wash stains on bibs or aprons? If you answered yes to any of the questions, we have the perfect solution for you!



A wicking liquid closed in a bottle that will give your favorite PUL hydrophobic properties.

What is our coating?

  • safe for humans and the environment,
  • ecological, consisting of only two substances,
  • odorless and invisible to the naked eye,
  • does not change the vapor-permeable properties of PUL,
  • durable, maintains its properties up to 13 or even 15 washes
  • and most importantly… cosmically simple in the application!

It is enough to thoroughly spray the material from the side without the membrane from a fairly close distance – 10 cm. If a ready-made diaper pocket or AIO is to be impregnated, avoid covering the absorbent material with liquid. Then let it dry overnight. And … you can enjoy the impregnation on your favorite PUL.

What does impregnation give?

  • significantly reduces the risk of leakage of the diaper,
  • extends the life of a diaper with minor diaphragm damage,
  • eliminates the problem of cleaning stubborn stains on bibs / aprons,
