What problem does it solve?
It is hard to cover a large item evenly with a spray: the shoulders get a double layer while the bottom of the sleeves stays untreated. Mountval Waterproofing Refresher 300 ml solves this with a rinse cycle, during which the product reaches the whole fabric equally. The limit: the product does not repair tears, leaking seams or a damaged membrane, and a dirty item has to be washed first.
When and on what should you use it?
- For rain and hiking clothing with membranes, when the protection has worn off after several washes.
- For tents and large textile items that are awkward to spray.
- When water no longer forms beads and starts to darken and wet the outer fabric.
- For backpacks, sports equipment and textile footwear.
- In the same cycle with Mountval Wash & Care 315 ml, when an item has to be both washed and treated.
