What this video covers

Nika hauls out her aluminium sailboat, Karl, at Marina Chiapas in Mexico for a three-month maintenance period.Watch After three years in the water, the hull requires extensive cleaning and a new bottom paint application.0:16 Divers Ronnie and Yeo clear the heavy marine growth before the boat is lifted.0:33 Nika spends three days grinding the hull to remove barnacle remnants and prepare the surface for primer.4:46 She applies TotalBoat two-component epoxy primer to bare aluminium spots, following a specific process to manage the metal's oxidation layer.5:20 She uses an etch wash to strip oxidation, requiring the subsequent primer application within one hour to ensure proper adhesion.7:39 Due to high ambient temperatures, she adjusts her workflow to account for the short pot life of the epoxy.9:02 When a shipment of primer fails to arrive, she secures additional Total Protect epoxy from neighbours to complete the intermediate coats.10:42 The final finish includes three layers of copper-free, ablative TotalBoat anti-fouling paint, with an extra coat applied along the waterline.5:38
