Product Information "Holmenkol Natural Tent Proof"

Holmenkol Natural Tent Proof is a spray-on waterproofing treatment for anything exposed to the elements outdoors. It reliably makes synthetic fabrics and canvas water- and dirt-repellent without compromising breathability. The formula is 100 percent PFC-free and biodegradable. Ideal for tents, camping tarps, awnings, sunshades, and backpacks.

Product Features

  • Water-repellent spray for synthetic fabrics and canvas
  • Water- and dirt-repellent—rain rolls right off again
  • Preserves the material’s breathability
  • No heat activation required—just spray it on and let it dry
  • 100 percent PFC-free and biodegradable
  • Ideal for tents, camping tarps, awnings, sun shades, and backpacks

Application

  • Clean the fabric first—for example, with Holmenkol Natural Tent Cleaner—and let it dry.
  • Spray Tent Proof evenly from a distance of about 20 cm until the surface is visibly wet.
  • Apply a second coat to areas subject to heavy wear, such as seams, edges, and roof surfaces.
  • Let them air dry. Heat activation is not necessary.
  • Test for material compatibility in an inconspicuous area first, and do not work in direct sunlight.

FAQ

Do I need to clean the tent before waterproofing it?
Yes. Dirt, pollen, and algae prevent the waterproofing from adhering. Clean the fabric first—for example, with Natural Tent Cleaner—and let it dry completely.
Do I need to activate it with heat, like with clothing?
No. Natural Tent Proof takes effect after air-drying. That’s the practical difference compared to many waterproofing sprays for functional jackets.
Is the product really PFC-free?
Yes, the formula contains no per- or polyfluorinated chemicals and is biodegradable. The water repellency remains reliable nonetheless.
How much surface area can I treat with 500 ml?
As a general guideline, one bottle is enough for a two- to three-person tent or a medium-sized tarp. For highly absorbent fabrics, you’ll need more.
How often should I reapply the waterproofing?
As soon as water no longer beads up but soaks into the fabric. For a tent that’s only set up a few weeks a year, once per season is usually enough.

The same principle applies to jackets and shoes. You can find suitable products under “Water-Repellent Spray for Textiles.”
