Placed above and below the paper with the translucent protective sheets, they create a sandwich that keeps the paper flat while moisture transfers by capillarity—the same principle as professional paper restoration in museums.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe fundamental difference with HUMIDITY STORM™:\u003c\/strong\u003e\u003cbr\u003e\nWith HYDROPUMP™, humidification and pressing occur simultaneously. The paper receives moisture while already under pressure. The active cycle lasts 30–60 minutes. Final dry pressing (24–48 hours, without foam) is always mandatory to make the result permanent.\u003c\/p\u003e\n\n\u003cp\u003eThe panels are reusable: after each session, let them dry completely on a flat surface before re-storing them.\u003c\/p\u003e\n\n\u003cp\u003e⚠️ The foams should be just damp—never saturated. Check the paper every 15 minutes during the active cycle.\u003c\/p\u003e","brand":"Spark \u0026 Polish®","offers":[{"title":"Default Title","offer_id":57116540764495,"sku":"SP-ACC-EVA","price":10.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/3138\/1327\/files\/hero_04.jpg?v=1779999452","url":"https:\/\/checkout.sparkandpolish.com\/en\/products\/pannelli-eva-foam","provider":"Spark \u0026 Polish","version":"1.0","type":"link"}
