We use Alexseal and Awlgrip marine coatings for our topcoats. Typically, a refinish project starts with any necessary repairs and fairing to the surfaces. Once the hull is ready, we prepare all surfaces with an 80 grit sanding and then apply the primer. Afterwards, we will prepare the primer with up to 320 grit abrasion and then spray the topcoats. Decks are usually coated with Ameron / Devoe epoxy 229. Below the waterline we prefer Ameron / Devoe 235 as a base for the anti-foulant coating.
