It comes in a spray can. You clean whatever you need to waterproof. You spray the spray on whatever needs to be waterproofed. You let dry. The item is now waterproof. The end.
Permanent Water-Guard is a solvent free, water-based fluorocarbon polymer water and stain repellent. It dries odor free and without U-V brighteners.
Guaranteed to remain effective even after 25 washings in Sport-Wash or Sensi-Clean. This is an extraordinary claim no other product is willing to make -- not even factory-applied Durable Water Repellents.
And the best news of all for us is that it re-waterproofs pocket diapers while keeping everything else the same.I love it! You don't need to throw those old diapers out (or pass them on to an unsuspecting mama over the Internet...) any longer. Simply wash your diapers, turn them inside out, stretch them (so that it all gets coated) while you spray the "wrong side" of the PUL layer (the shiny side), and then let it dry. I did all of our diapers at one time outside on a sunny day. It worked so well that I pulled all of our old diapers out of storage (waiting for the next baby) and sprayed them before packing them up again.
