What this video covers
Sven Yrvind creates a perfectly flat mounting surface for a hatch gasket by using gravity and the self-leveling properties of epoxy.▶ 4:03 To prepare the surface, he sands the area until flat, then applies a low-viscosity epoxy resin that flows to fill remaining gaps and imperfections.▶ 0:53 He notes that the resin’s slow cure time and low viscosity allow it to settle into a level plane, effectively creating a seal that manual sanding could not achieve.▶ 2:27 He also addresses the strength of friction rings used on the boat, confirming that the 19-millimeter rings are rated for 5,500 kilograms, while smaller versions are rated for 2,000 kilograms.▶ 0:37 After identifying a small leak in the epoxy application, he seals the pinhole with melted silicone to ensure the surface remains watertight.▶ 4:53 The process relies on natural leveling to ensure the hatch gasket seats properly against the hull.▶ 4:03
