Take One Very Wrecked Boat(part 2)
Ok as I mentioned in part 2 I was going to have to go in with Nitromors to remove some paint . If you are going to do this make sure you do a small test patch or two first . I did and was ok to go ahead .
Here is the first coat of Nirtomors doing its thing , that is how much paint I have to remove from all the way around on the inside and the same on the outside
Right 3 coats , 2 L of Nitromors , lots of wire brushing and a day later got me to this ......
It is now ready for a sanding and a clean before painting BUT after removing the paint I had I can see there are still 3 different types of paint on here and also the Nitromors had a very slight reaction to some of it , but I do mean very slight . Seeing this though and seeing the 3 types of paint really is a big worry due to the fact I have no idea what they are and I am wanting to apply a 2 pack epoxy over it and there are so many things can go wrong . Sleepless nights or what !!
Here is the paint that I am going to use and the reasons why shown in the table . I had all this shipped over from England from
Shepherd Marine - Jotun Marine Paints, antifouling, boat paint, marine paint, deck paint, boat coatings they were very good putting up with the many many questions I had and all the emailing back and forth before I was finally happy and placed the order ..
Suitable for above waterline? Yes
Suitable for below waterline? Yes
Suitable over aluminium? Yes
Suitable over concrete? Yes
Suitable over GRP? Yes
Suitable over steel? Yes
Suitable over wood? No, with the exception of marine ply
Gloss level Flat
Gloss retention Good
Flexibility Good
Abrasion resistance Very Good
Chemical resistance Excellent
Solvent Resistance Excellent
Water resistance Very Good
With this choice of primer there is no need for any top coat on the inside of the boat , just 2 coats of the HB , first one in grey , second in white , the reason for the 2 colours is so I am sure I have not missed any when applying the second coat .
You will see a small pot of low temp additive , the reason I have this is because it is still getting cold at night and I still want to keep the curing process going 24 hours a day ( it would stop happening at night otherwise ) With this added the curing will keep happening down to 2c . Even with this added because of the average temps at this time of year it is still going to take around 2 weeks for the paint to fully cure ....
Take you time when thinking about all your paint options as it is a minefield !!
So before I sand the whole lot down I have decided to do a few test patches to see what reactions I get from the primer ...
The things that could go wrong include a reaction right away when applying the paint , like melting , bubbling , blistering etc , but I was lucky and that didn't happen BUT that doesn't mean it is for sure ok to go ahead and paint the lot because another thing that can happen is there might be a reaction that you can't see that actually interferes with the curing of the new paint or the adhesion of the new to the old , so now I have to wait ......
The patches have been on for about 4 days now and do seem to be curing ok but to say all this has given me sleepless nights would be a understatement
So the point being if you don't know the full history of your boat and there are any unknowns then really take ya time , do the research , prep work and test , test , test as you going along because if you don't you could find yaself in a whole pile of ****
So any questions ?? Don't ask me !!!
