Cosa tratta questo video
The crew of the aluminum catamaran Delos 2.0 prepares the vessel’s interior for professional spray-foam insulation.0:17 The process requires completing all structural welding, installing AC and DC electrical conduits, and finalizing plumbing runs through bulkheads.1:00 To prevent corrosion, the team cleans the aluminum surfaces with aircraft-grade Simple Green and applies a protective coating of Nyalic, which beads water and seals the metal from oxygen.10:15 In areas where spray foam is impractical, such as around steering linkages and service runs, the crew installs 25-mil closed-cell foam sheets to maintain access for future maintenance.2:40 The team uses a wet-dry vacuum and blowers to ensure the bilge and hull surfaces are completely dry before applying the Nyalic.15:05 The project requires approximately 4.2 quarts of Nyalic to cover 1,345 square feet of interior surface area.22:58 Proper surface preparation and sealing are essential to prevent oxidation and ensure the spray foam adheres correctly to the aluminum hull.
