When to remove old bottom paint vs recoat in South Florida

Every few years a boat owner in Miami faces the same question at haul-out: does the old bottom paint come off, or can the yard just scuff it and roll on a fresh coat? Getting bottom paint removal right in South Florida saves real money, because the wrong call either wastes a coating that still had life in it or buries a failing surface that will blister within a season. We get asked about this constantly after we clean a hull and find paint that is chalking, peeling, or so thick it is starting to crack.

Recoat When the Existing Paint Is Sound

If the antifouling is still well-bonded, has not built up to more than a few millimeters, and the hull is not blistering, recoating is the cheaper and faster path. A light sand to break the gloss, a wash to pull off chalk and slime, and a fresh coat of compatible paint will usually get you another one to three seasons depending on the product and how hard the boat works. The key word is compatible: layering an ablative over a hard paint, or mixing copper chemistries, is how owners end up with a surface that sheets off in patches the following summer.

Strip the Paint When the Layers Have Failed

Full removal becomes the right answer once the buildup is too thick to bond reliably, once you see alligatoring and flaking, or once moisture has worked under the coating and started lifting it. In Miami the warm, salty water accelerates all of this, so paint that might last a decade up north often needs to come off here much sooner. Soda blasting and chemical stripping are the two common methods; the choice depends on the substrate, because aggressive media on a gelcoat hull can do more harm than the old paint ever did.

How Our Underwater Work Affects the Decision

Most of what Aqua Pro does happens in the water, not on the hard, and that gives us a useful read on your paint long before haul-out. When our divers clean a hull, we can tell you whether the antifouling is releasing the way it should or whether it has gone hard and slick and stopped protecting the boat. We document each cleaning with before and after photos, so over a couple of visits you get an honest record of how your coating is aging instead of a surprise at the boatyard.
