Thanks for your question.
Tefcite can be removed from the hull by a variety of methods, however, it will be more laborious than marine paint
i.e. it cannot be hydroblasted off.
Tefcite can be removed via hand sanding
or hydroblasted with blasting media
like glass beads or sand slurry. We are working on a protocol using dry ice to "freeze" make the plastic coating making it more brittle and easier to remove without damaging the fiberglass
hull. Obviously, metal hulls can be sandblasted down to bare metal and re-coated with paint
It's important to mention that Tefcite need not be removed at all. It can simply be painted over, and offers an excellent substrate to adhere epoxy
paints to. In this case, we'd recommend that the outer surface again be surface prepped to provide a 1-3 mil depth
profile to help the paint anchor
to the surface.
Tefcite effectively seals
in the fiberglass
hull to prevent hull blistering. A non-anti-foulant sealant
can be applied to the hull at about 1/2 the cost of Tefcite.
For older hulls with pitting and damage to the gel coat, we recommend applying this non-antifoulant sealant
to the hull prior to Tefcite. The sealant is a water
impermeable barrier, that the Tefcite topcoat can be readily "melted" into. In this case, the sealant/Tefcite combination offers a partial restoration
of a fiberglass hull (below the water line).
While expensive, the entire vessel could be powder coated in the sealant, and painted applied above the waterline, and Tefcite applied below the water line resulting in a complete restoration
of the entire vessel. For special projects this may be a option for serious boat maker enthusiast's.
Again, the process of spray on powder coating using a proprietary plasma spray system is totally new to the boating
world. The method to spray molten plastics infused with copper metal as an anti-foulant which is both highly impermeable to sea water corrosion
, highly abrasion resistant, and durable to repeated cleaning
without damaging the coating's performance - maybe the next evolution of high performance marine coatings.
Keep the questions coming, it's important that I provide accurate information on the technology so boaters can make an informed decision on whether a Tefcite hull coating is the right application for their investment.
