blasting ferro/epoxy tar/flo coat

[lilianroyle]

Has anyone experience of grit blasting a ferro hull? The hull 25 years old so presumably very hard. Will blasting damage it?

My plan is then to paint with epoxy tar (replacing the current coating of bitumous paint) The paint distributors say there is always a risk of moisture with ferro hulls. Anyone with experience of this?

I also want to blast the fibre glass decks (years of accumulated deck paint) and resurface with flocoat + an antislip additive is this a viable idea and what additive would be best.
many thanks to all respondents

No problem at all blasting the hull, you may reveal any voids or soft areas which may need to be filled

DO NOT GRIT BLAST A FERRO HULL IT WILL DAMAGE IT

If you wist to blast use soda blasting.

I started to grit blast by ferro hull and it started to remove the ferro surface its self so I stopped.

I stripped all the paint off my ferro hull using head guns to limit the temperature which if too high causes the ferro to break off.

Following removal of paint with head guns I sanded with large angle grinders with 28 grit sanding pads.

When I get to start repainting I will use epoxy thinned with methylated sprit so it sokes in and keep painting it wet on tack on until it stops soaking in . The final finishing is then as conventional paint finish. I will be using epoxy tax below the waterline . You can use it above if you don't mind a all black hull. You will not be able to paint any other colour over the epoxy tax as it will bleed through in time.
