HUMIDITY STORM™, one card at a time.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHUMIDITY STORM™ is the Spark \u0026amp; Polish® method that rehydrates cardstock fibers in a protected environment — without ever directly wetting the card. The card enters the Humidity Box, absorbs moisture from the air (target: 65–85% RH), the fibers relax and become malleable. The XL Plexiglass round press sets the new position in 24–48 hours.\u003c\/p\u003e\n\u003cp\u003eThis kit covers the entire cycle: humidification, manual intervention on edges and corners, final pressing. One card per session.\u003c\/p\u003e\n\u003cp\u003e🎯 \u003cstrong\u003eWho it's for:\u003c\/strong\u003e Those new to structural restoration. Those with cards that have waves (Pringles effect) or slight curvatures and want to learn the method correctly from the beginning.\u003c\/p\u003e\n\u003cp\u003e✅ \u003cstrong\u003eHow it works:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1. Humidification\u003c\/strong\u003e — The humidified pad creates a controlled microclimate in the Humidity Box. The card, placed on a clean sleeve, absorbs moisture in 30 minutes–2 hours depending on the damage. It should be flipped every 30 minutes for uniform hydration on both sides.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2. Manual intervention\u003c\/strong\u003e — While the card is still pliable, work the edges and corners with the Foil Precision Silicone Spatula and the synthetic bone Folder. The translucent protective sheets protect the surface during handling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3. Pressing 24–48 hours\u003c\/strong\u003e — Card between the discs of the XL round press, 4 clamps at the corners with uniform pressure. The fibers stabilize in their new position. At the end: sleeve + top loader immediately.\u003c\/p\u003e\n\u003cp\u003e💡 To treat multiple cards in parallel or add the HYDROPUMP™ technique, consider the Advanced HS Restoration Kit or the Complete Professional Kit.\u003c\/p\u003e","brand":"Spark \u0026 Polish®","offers":[{"title":"Default Title","offer_id":57218811035983,"sku":"SP-KIT-HS-BASE","price":54.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/3138\/1327\/files\/hero_06.jpg?v=1779978455","url":"https:\/\/checkout.sparkandpolish.com\/en\/products\/kit-restauro-base-humidity-storm","provider":"Spark \u0026 Polish","version":"1.0","type":"link"}
