Once again I'm looking for sound advice on quality workmanship;
Our yacht is manufactured with epoxy
which was spray painted after fairing. We then had anti slip sprayed on all the high traffic areas. I'm not sure which paint
was used but normal car Duco paint
rings a bell. It is now time to redo the anti slip areas again. We are looking to do a quality job and we thus cannot just spray paint over the old anti slip as it will most likely not bond well. But sanding
the old anti slip is only touching the pinnacles of the old anti slip sand granule and not the actual surface area.
How do we properly prepare the old anti slip surface for the new and ensure a good bond?
